iRiver SlimX iMP-400 CD / MP3 Player (Silver)


Compras Nikon
Bluetooth
The iMP-400's chrome-style design and incredible features redefine expectations for what's possible in a portable CD player. From its circuit design to its final manufacturing spec, iRiver has channeled all its efforts into delivering the best CD and MP3 sound quality. The player supports WMA and ASF formats as well as discs burned with Winamp playlists. Additional formats, such as AAC and MP3 Pro, will be supported in the future through simple firmware upgrades, by which iRiver can add and modify player features.

The iMP-400 comes with quality iRiver wrap-around headphones, offering far superior quality to standard CD player headphones. The player offers eight preset equalization curves and one user-defined curve (choose from normal, pop, rock, jazz, dance, classic, metal, U-Bass, and user EQ). Auto EQ changes automatically according to ID3 tag information, and a battery indicator lets you know when you're low. The player also performs perfectly in the face of external shocks because of iRiver's unique anti-shock algorithm, iRiverShockFree. This feature maintains supreme control over the server, so it can accurately read data even in the face of extreme vibrations, letting you listen to continuous music.

An easy-to-read, four-line LCD shows every bit of information needed, and an FM tuner comes in handy when you're traveling by tracking the frequencies to maintain reception as you move. The iMP-400 uses 16 MB Flash memory to support the display of Chinese characters (traditional/simplified)--37 languages are supported. The player also recognizes discs in Packet Write format, which enables you to use CD-RW discs like PC hard disks, offering the ease of using discs and of saving and deleting songs. Finally, the player prevents its rechargeable batteries from overcharging, and a discharge function fully discharges batteries before recharging, thereby preventing the diminishing of rechargeable battery capacity.


1 one of a kind!
although we dont have this specific product! my Mother owns a Slim X product mp3/cd player! we go on lots of vacations in the car and so we need LOTS of music!hee hee hee!!! we spend weeks and weeks making music mixes! and take off, on the trip listening to cds!
the quality of the frame is wonderful it has yet to be "rusting" the remote has broken once but that was my fault when i closed the car door on it! it was an easy fix! the batteries were rechargable and theres a car adapter so if the batteries died on a road trip we could still listen to music and recharge the batteries at night when were not on the road! mom also runs a few miles in the mornings and takes the player with her she said it doesnt skip, so i was sold... (i even "borrowed" it for a while when running, myself!...^_^) and since mom doesnt listen to the raidio she doesnt have extra buttons to gripe about!^_^ well i love moms slim X and my friends have similar slim X products also so i highly suggest slim X products.
enjoy!!!!

2 Overall i-river quality
This is a warning about i-riverI do not have this specific i-river product, but I have purchased two of their products in the past, and the quality of both began to deteriorate within months. Both of them damaged numerous sets of headphones, wearing the connectors to the point that only one earpiece would work. On one of my players, the backlight on the LCD stopped working, and on the other the connection between the player and the USB chord no longer holds properly, preventing me from changing any of the MP3's on a 64 MB player. When I contacted the company about these problems they gave me the good ole runaround, basically vouching for the poor qaulity of their products. I will not being buy any of their products again.
3 Well Designed
After much searching online for a good mp3 CD player, I decided that the iMP-400 looked like the right CD player for myself (unfortunately this was just a little before the release of the iMP-550). It had many features that appealed to me, and I have remained happy with it over the last 9 or so months.

On the upside, I have loved all the features about this player, with the ability to play mp3's, audio CD's, AND have the radio function to be the most prominent features. The svelte styling of the player has impressed many people, along with the slim size of it. I also have defiantly put it through its paces by taking it camping/hiking along with my everyday use. The layout of the remote control, although somewhat tough to learn at first, provides instant access to all of the important functions. Also impressive is the inclusion of many minor features such as the inclusion of an audio-out port to connect the player to a sound system (I have also used it to connect a second set of headphones to share music with a friend). Another is the ability to select the next track to be played with out interrupting the current song; this ability is still available during random mode. The fact that the player uses firmware has allowed updates to include new modes and features, and even a snake-style game!

On to the bashing section of my review:
One of the faults previously touched on by other reviewers is the time that this system takes to power up. When I want music, I want it NOW, not 30 seconds from now.
Recently, the remote control's center button stopped responding. By taking apart the control (and probably voiding its warranty) I determined that the cause of the problem was that the pin attached to the backside of the button to depress the capacitor had inadvertently snapped. Although annoying, the problem was easily solved with the use of some gel-like super glue.
The player turns off when it is connected to, or detached from, the AC adaptor, which means that I have to go through the long boot process again.
My final grudge (although not too much the companies fault) is that only non-protected WMA's can be played (something I only found out after I had encoded most of my music library with the protection on)

All in all, if you want a mp3 player that also plays your CDs, the iRiver series is as good as they come. But if you don't plan to use its ability to play standard CD's too often, you may be better off with a hard drive player.


4 solid player
I've had the imp 400 for 3 months now, and it has performed very well. I like
sound
volume
controls
solid feel
accessories
anti skip
car adapter
pouch

I don't care for the fit of the headphones. I had to sand down sharp edges over the ears before I could comfortably wear them. The imp 400 is slightly expensive but if you need all the accessories coming with it, which I do, it is actually a great deal. I've dropped it with no consequences. I would recommend it.


5 Perfect for the "spouse"
My wife isn't interesting in ripping CDs, creating mixes, MP3s, etc. Her goal was a unit that would play her large CD collection and would accept the crazy disks that her crazy husband generates.

Given that sort of anecdotal background: this is the perfect player. Interface is easy to use (passes the "spouse" test once again), music quality is good and it is very tolerant of shake, rattle and rolls.

I only rate it as 4 out of 5 because I personally don't like the disk form factor. If that's your thing, though, this is the player for you.


6 EXCELENT RADIO!!!
Once upon a time in my life I bought the big brother of iMP-400, iMP-550.

But the radio was worthless!!! It was only possible to listen to the strongest radiostations, standing still and holding up the earphone cable. Tried it at the absolute center of Stockholm (the capital of Sweden), and could bearly hear anything.

...so I returned the player to the store and, with some hesitation, bought the iRiver SlimX 400 in stead. I became very positively surprised! The radio in iMP 400 is very good, I can use it almost anywhere, maybe not in the subway but rather far down the stairs to the subway. However, the batteries only last for 5-10 hours (but charging is easy), and putting the mp3 on takes about 45 seconds and a usual audio-cd takes about 20-30 seconds (iMP 550 had the same delays), but I can anyway strongly recommend SlimX 400.


7 A question please
Can anyone please tell me about how many songs u can upload on to this mp3 cd player?
Thank u!! my e-mail is boa4-ever@hanmail.net
8 I use it Every day
I did lots of research before choosing this. I wanted an MP3 player that would allow me to recharge the included batteries with the adaptor, was little and sleek looking, and had lots of cool features. The player has exceeded my expectations.
1. The remote is small, and sometimes my finger accidentally slides off when I'm in the middle of fast forwarding or rewinding the track, so I accidentally move to the next track. But, I just go back and start over. (I listen to a lot of audio books, so tracks can be an hour long, so I'm holding my finger on the button for a while to get to my place.)
2. The screen is tiny, but it's not that difficult to read. (My vision is far from 20 20.)
3. It has many cool features that are not in the features list, such as fading in right where you left off (it saves several CDs), ability to change the ff/rw speed, interval repeat, auto shut-off, autopause, visualization, time, beep tomes to aid the visually impaired, and contrary to what the features list says, it does have a sleep timer.
4. I've had mine for almost four months, and it's definitely worth every penny. (I am a graduate student, and money is hard to come by.)
5. There are many other features that I have not listed. Almost everything can be set or adjusted.
6. There are many features that I haven't even used yet.
7. When hurricane Isabel came through, we listened to the radio. It was clear and the batteries lasted nearly two days.
8. I accidentally spilled a cup of water over it this morning. I thought I was going to have to take advantage of the one year warranty, but after a couple of hours, the remote dried out. Now it works just fine. No water went into the CD part.
9. If you don't mind extensive menus, this is an excellent player.
10. Plugging the headphones into the jack on the remote provides a much better sound than plugging them into the jack on the player. Headphones can be plugged into both jacks at the same time, but it cuts the volume almost in half.
11. I bought some Panasonic T70 Travel Speakers for about 20 or 30 dollars at my local Circuit City. They are the perfect compliment. When I move from room to room, I can carry the player and the speakers in the same hand.
9 Let's clarify a couple points
I've read these other reviews and found a few errors or misconceptions I'd like to clarify. First of all this is an excellent unit and have my reasons to prefer an mp3 cd player over a jukebox but won't get into that here.

One reviewer complained about all the wires with the remote and odd battery pack attached. I find that when I use the case provided and attach it to my belt, with the remote, there it stays. You can manipulate as much as you desire and only have to handle the remote. If for some reason the 7~12 hour battery life isn't enough, just attach the AA battery pack and slip it into your pocket. You don't even know it's there. As for the remote clip being opposite the buttons causing you to inadvertently change the controls as this same reviewer complained, use the hold switch and this will not be a problem. I'ts right on top of the remote and very convenient to unlock/lock before and after fiddling. Then when you press the clip to retrieve or tuck it away nothing is changed. This is way better than smudging the display and was well thought out.

At times when exercising or bike riding, I prefer not to use the remote so I just plug the headphones directly into the unit. In the event I should need to change something, the multifunction jog wheel on the side lets you play, pause, next track, previous track, switch modes between cd and fm, change FM presets when in preset mode or search next/previous station when not in preset mode and finally adjust the volume. A lot for one little jog wheel to do!! The volume is adjusted using next track (volume up) or previous track(volume down) and holding the wheel until the desired volume is reached. The one quirk is that you cannot adjust the volume this way when in FM mode. For the few times I've needed to do this, I switched to CD mode, set the volume and switched back to FM. Switching modes is done by holding in the play/pause (pushing in the wheel) until the mode switches. The only thing I couldn't figure out is how to turn it off from the wheel. No sweat though, just open the lid and the unit shuts off but only does this when in CD mode, another quirk. With all these controls available, although you cannot do everything, the unit is very usable without the remote. Unfortunately the manual doesn't tell you any of this.


10 Top of the CD MP3 player market.
CD MP3 players are quickly becoming obsolete, why go to the trouble of burning CD's when you can just upload songs 20 times faster. Memory wise CD players are super cheap, 1 CD costs about a 20 cents compared to the big bucks for spare memory cards, that to me is the only advantage of CD MP3 players. CD players are big and bulky and not easy to fit in ones pocket. The no skip feature is touchy at best, sometimes it great sometimes it isn't. Battery wise, its inevitable that CD players will use more batteries then rigid MP3 players.

Overall if your in the market for a CD MP3 player buy this, its top of the market, but if your just wanting a portable MP3 player, go look at MP3 players that don't use CD's.


11 Fantastic, will be close totop of line for at least 2 years!
This player is the best one can ever own for at least the next 2 to 3 years. It has possibly everything one could want in a mp3 cd player, including firmware upgrades! I admit it is a bit overpriced at 150 odd dollars, but hey I bought mine at 190 and was very happy with what i got. (I still am happy with it) If you look at all the stuff youre getting for the bucks, you might look at the price tag a bit differently.

Like everyone before me has said, you should research all the players available before you take the plunge. i would recommend checking out sony, which some pretty hardy ones that have the minimum necessary features. If youre looking for a player that can play mp3 cds and regular cds and don't want to spend too much, then a sony is your best bet. But if you want to take control of what youre listening to, you must check out the iriver stable.

in terms of what is available from iriver, the 400 seems to be the best of the lot, compared to its siblings, the 550 and the 350.
the 550 comes with digital optical output, which apparently helps you if youre wanting to pass this output onto another system. They also claim that it looks better, but i guess that might vary from person to person. i for one am very happy with the looks of the 400 and i think it wont look dated even after 4 or 5 years! Besides i dont notice too much of an improvement in the 550. It seems like you pay an extra 30 - 50 bucks for a different look and an optical output capability.
as for the 350, for starters, I don't like the look of the player. It looks like its dying to get dated. Its too sleek, possible great looking for 2002, but I don't think I like it. I definitely prefer a cleaner look on my player! As for the features it doesnt have as many preset equalizer modes, and it has 16 mins of buffering as opposed to the 32 mins on the 400. honestly im not sure if that makes a big difference in performance! but where the 400 scores is in the sheer value of the entire package. you get a headphone for starters, which most of us prefer over earphones, it also comes with a complete car kit and i guess these would cost about 35 to 40 bucks if you wanted to buy them separately! of course on top of this, you get a much better and easier-to-use remote. the 350's remote has fewer lines and it doesnt have the clean button interface like the 400. Id say, if your next meal doesn't depend on the 40 odd bucks you might save (if you went for the 350) youre better off with a 400, considering what an awesome deal it is!

if you read all of this, and are still interested in the 400, lets get to the good and the bad.
The 400 has "VERY" good battery life. i dont think it goes for 12 hrs like the company claims. but it does about 7 to 8 hours (with all that constant fiddling i do!) which is fantastic!
the other thing thats great about this player is that it has a discharge and charge mechanism and an auto-cutoff mechanism which means you could leave the player plugged in(to recharge) and walk away someplace. if youre wondering how that helps, thats because most rechargeables last longer, if you dont leave them plugged on after theyre fully charged and also if you can run them to a complete discharge once in a while. this was a total opinion swinger, when i was looking for a player! I was looking for a player that had a builtin FM receiver, and yes this has it, and whats better it comes with 20 presets! (and the reception is decent for a portable player) Finally, Its got firmware upgradability which is a HUGE plus!

as for the cons, the one thing i dont totally admire is the lack of a stop button and a volume control on the main unit. there have been times when i dont want to have the remote - like when im jogging or something. It would have been great if the main unit had this basic functionality, so I could play audio cds. But I guess that's only noticeable, if you sorely need that ability. i knew about this when i bought the player, and willingly decided to put up with it. so if you think this isnt a big deal, hey thats great!
Theres one thing that no one seems to have pointed out. this player has a "SUCKY" battery indicator. basically the battery indicator on the remote has 4 bars (4 for full and 0 for almost out) For some reason, the indicator cant seem to make up its mind between displaying 3 bars and 1 bar. at times you boot up, to see a single bar (which can be worrisome if youre going out for a long trip someplace). but then hey crank up the volume up a bit and let the player play for sometime, and chances are youll see three bars?? what on earth is that? I guess its some stupid bug in the design or probably something with the way batteries work (because ive also seen this happening in other battery operated devices) But this thing in no way affects your battery life.

in summary, this is a fantastic package and you must go for this, if you think you need a very smart player (with FM capability) at a very good price. i am sure you will love it as much as i did. In fact I worship my player these days!!

Pros:
Battery life
Discharge and Charge option + auto cutoff during recharge (great for rechargeable batteries)
FM player
Firmware Upgradability
Worshippable!!

Cons:
No stop or volume control buttons on main unit, for standalone operation
Sucky battery indicator (cant make up its mind at times)


12 Don't buy it!!
DON't BUY this item. It's not available at Amazon's warehouse!! I ordered the item 3 weeks ago...and still haven't received it yet...no...i should say it hasn't been even shipped yet. Now they extend another 3 weeks for the estimated shippment date (note: shippment date, not even delivery date). It's awfully pathetic...why didn't Amazon honestly tell me that the item is out of stock?? Then i wouldn't have bought this item in the first place. Extremely disappointed with the integrity of service!!!
13 Good Overall
It's a great addition to any mp3 fanatic, not to mention the options this has and other mp3 players don't. If you have music with id tags in other languages, the iriver is great for viewing those info, since imp-350 and newer versions all have multi-language codecs. There are some other nifty stuff, like customizing your own intro screen...However, this model does make some loud noisy sounds when trying to start up, shut down, & spinning the cds. I heard the IMP-350 is a little better in that respect. And sometimes, it would play the wrong song (when I specifically said I want a song to be played). That doesn't happen often, however. Be aware, there are no earbud headphones included...it's those around-the-neck types. The internal batteries are great, but they only last 5 hours at the most, and less with each wear. But, it's pretty good in the trauma department; shaking it while playing a cd or dropping it doesn't do much damage...the silver casing makes marks virtually undetectable. Ah...every good product comes with some flaws, what can I say? Nothing is perfect.
14 Almost perfect for this picky consumer...
Before venturing into the costly world of MP3 players, I wanted to be well informed and researched almost every MP3 player available on Amazon. Flash memory is the most convenient type but as a good one (in terms of memory) can be [$+], I decided a MP3 readable CD player would be an excellent solution. I am very happy with it--although it has a few design issues, the iRiver iMP-400 certainly lives up to its hype.
The Good Stuff:
1. Tons of features to customize to your liking (languages too)
2. Beautiful slim design
3. Good sound (has an customizable EQ)
4. Back-lit remote which definately increases its readibility
5. Easy to sort through folders and lists
6. Has a radio (reception is okay)
7. Comes with rechargable batteries and has AC adapter
The Bad Stuff:
1. Awful headphones (I replaced them with the Sennheiser MX500)
2. Unless the hold button is on, the remote buttons are easy to push accidently as the remote itself is only about the width of two fingers
3. Remote control cord is too long (~30 inches)! With my headphones plugged in, I feel like an octopus dragging so many cords around. They tangle at every opportunity!
4. Most of the necessary options are on the remote, the main console offers no text
5. My player has only given me about half the battery life it advertises
6. Weaker bass (even with the tweaked EQ) so beware if you like rap, R & B, soul, etc.
7. Price ... is hard to swallow
8. Console can get warm if you play it for a while (I generally listen up to three hours at one sitting)
Still, a product worth recommending if you are looking for customizable features and slimness! If you just want something that will simply play the songs, I recommend the Sony D-NE710 ATRAC3/MP3 CD Walkman. It has better bass, plays Sony's ATRAC3 but has little else in comparison.
15 my god
when i bought it, it was 174.99. ^.^ i can't believe it~~
16 Technical data displayed is confusing
I have a question: the technical data list for the iRiver SlimX iMP-400 CD/MP3 Player said that it didn't include the remote control in the box. Is this true? I read a review where was mentioned that without the remote control the CD player was really difficult to use, yet other reviews talk about the remote. Please tell me if the remote control is included with the CD player, and if not tell me if you sell it and at what price. Thanks for your assistance.
17 Great, especially now with the %25 rebate
I bought my cd player at J&R and it came with the cd player, earphones, AC adapter, cassette adapter, car adapter, and cd case. The cd case and earphones (meh plastic wrap around T-T) arnt exactly the best and as far as I'm seeing, amazon doesnt offer the car adapter and cassette adapter (which isnt very important to me). Anyway, so far there were there were no skips even when i bring them into the NYC Subway--which i can promise, is far from a smooth ride. The only complaint I might have is that the sound is not very loud even when i approach the maximum (note: this is when im on the subway, when I am in a quiet enviroment it is loud enough). This might be due to the earphones so I wont complain yet till I buy better ear phones. Also a unique feature that I havent seen in other reviews is the fact that it includes the game snake after you upgrade the firmware (sorry you need a cd burner to do this.)

Summery:

Good:
1) There are actually firmware upgrades
2) Snake :D Even though the screen is small, if you are not blind it should be ok. It is simply something to do while there is nothing to do.
3) I dont know where the short lived batteries came from but I played with the snake game (which causes the leaves the back light on) for ~40 minutes--while i listed to music--and I listened to the player for about 2 hours total today when I brought it out. Unless the battery indicator was lieing, It had not decreased by 1 box out of 4 which is good considering some reviews claim that the cd player only lasted 2 hours.
2) There is a line out in addition to the normal one used for the remote+head phones. I believe line out and the headphone line are exactly identical and interchangable. I was able to plug two headphones in and they both work except the sound was a little softer which--to me--is acceptable.

Bad:
1) As said before, the without the remotes the cd player is almost useless
2) The cd player makes sounds resembling ones of remote control toy vehicles. This is ok for me but to other people this might be a problem
3) Not enough bad problems to deal with j/k(joking) ;D (had to put this here)


18 I love it
I read one review by an engineer that said he couldn't figure out how to use it. Well I say he wasn't schooled very well. I figured out how to use it pretty well without even looking at the manual. I have no complaints about it at all. I love it!!
19 awesome mp3 player
great sound quality, superb design, easy to use remote.
20 I forgot to mention this really bad things...
It occasionally can't play a track properly and freezes. The only way to sort try it is to flick around tracks or even turn it on and off, which is a pain because...

Depending on what CD it is playing it can take 20 seconds to turn on! Criminal really. My £15 walkman never did that.


21 The Good... And The Bad
I did a lot of research and decided that this would be the best MP3 player for me. It was against my existing cassette walkman and NetMD.

Pros
----
The sound quality is pretty good, a lot better and louder than my walkman and plays at the right speed too.
I can play all my exsiting CD's + new MP3 ones.
Sexy looking.

Cons
----
Battery life is terrible, I get about 3 hours for CD's on batteries, so I have to charge it every other day. I expect the battery life playing MP3's will be close to 10 hours. Don't believe their site.
Bulky, too big to fit in my pocket, I had to buy a bag for it.
They've just realesed the iMP 550 and it looks sexier.
Skips like on most damaged CD's.

All in all, seriously consider you options, it's ...a bit of a pain to transport if you are travelling because you can't fit it in you pocket.


22 An excellent portable mp3/fm player
This is a great portable cd/mp3/fm player. Overloaded with many features. I only use this in my car, so im not sure about the battery life. The iRiver website says the upgrade to ver 1.2 should increase the battery life by an hour.

The package comes with a car adaptor setup which I was not aware of until I got it, which was very nice. Two rechargable batteries, an ac adaptor an external battery pack for AA's. Also comes with a handy pouch/carrying case. Headsets sound great not top of the line but very durable.

The remote is very, very cool looking with the blue backlight. I always keep it lit. You cant operate the player without the remote. I hope iRiver comes out with a wireless, that would be sweet!

The firmware upgrade from the iRiver website works but got a bit tricky. Its not very well explained and I found by trial and error you have to unzip the .exe files to your HD then burn the .hex files to your blank CDR. Do not burn the .exe files to your CDR. Only one .hex file per CDR disk. The unit comes with version 1.00, You can't upgrade from ver 1.00 straight to 1.20 you have to upgrade in steps from 1.0 to 1.01 to 1.02 to 1.2. On some tries to install the firmware I got a "no disk" msg meaning the player is not reading the disk. Just retry a few times, the player will eventually catch on. When the upgrade is completed I did not loose any presets which was very nice.

I had this in my car for a few months and never skipped once. The unit itself looks delicate, I dont believe this would be the unit to buy if you want to go jogging everyday. I would buy this for you car or as an attactment to a audio component you already own.

The sound quality is outstanding. Has very nice equilizer adjustments and about 8 default equilizer presets. Has a multitude of other settings to keep you busy. Once you get used to the iRiver format it becomes simple to understand and navigate through. Compared to another portable mp3 player I used in my car before using this one, it does seem to take a bit longer to queue up music, even on a disk without folders. Its not a complaint just something I noticed.

The FM stero works great and picks up all the stations in the Los Angelos area. 20 presets help make navigation very easy.
I highly recommend the iRiver-imp 400 (in red!) and gave it 5 stars!!!


23 Very disappointed
This is a physically beautiful unit, which should win awards for design. You can't judge a book by its cover, though, and I find myself a very disappointed user of the iMP-400.

First, the unit recognizes none of the mp3 CD-R's I recorded on my G4 Mac's SuperDrive (under MacOS 9.2), even those these are easily read by my Kenwood CD player in my car. Second, often, while playing an audio CD under non-jolting conditions, the player just stops and does nothing. I have to select another track on the CD to get it going again, and then select back to the track the player had originally stopped on. Third, the remote unit is very difficult to 1) see, because of the microscopic size of the characters on the LCD, and 2) operate, because it is almost impossible to not inadvertently push a button while clipping the remote onto or off of your clothing.

On the positive side, the iMP-400's FM tuner is the only digital unit I have encountered that will tune to a frequency that ends in an even number (e.g., 90.2 megahertz). This is important for those who watch TV in health clubs that have wireless audio transmitters, which are usually tuned to even-numbered frequencies so as to not interfere with broadcast FM stations, which always have odd-numbered frequencies.

The sound quality of the unit is very good, but to get it you have to spring for some nice occlusive ear buds (...). The headphones that come with the iMP-400 don't sound good at all.

I found the manual to be very well illustrated, but the text is way too sketchy and obscure. To figure out how to do something simple, I have to read the page over several times. The battery charging function is very weird. Instead of just plugging in the unit to charge the battery, like every other device I have ever owned, you have to 1) turn on the unit, 2) push the Stop button to put it in charge mode, and 3) select whether you want to just charge the battery, or charge it after completely discharging it.


24 On the Road Again...
For those who, like myself, have become addicted to storing and playing their music in mp3 format, this player is just about the best thing on the market. No other player except iRiver's own 350 model seems to be able to handle the combination of mp3 format and CD-RW media without problems. This model is an improvement on the 350 model in this area, as it does not seem to be subject to the sensitivity to temperature that occasionally plagued the 350.

The remote has been re-designed from the 350. While I find the new arrangement of buttons and switches to be better looking, the controls are not as easy to handle in 'sightless' mode, as when I'm using it in my car. Their positioning versus the spring attachment clip is also a problem, making it difficult to attach the remote without inadvertently hitting one of the switches. But when trying to go through multiple directories of songs, navigation is much easier than with the 350, and you don't really need to refer to the manual to figure out how to do this or to get to any of the other option settings.

Skip control has also been improved (not that the 350 was a slouch in this area), so it is now almost impossible to make the player skip, even when jogging with the player in a vertical position. And while jogging, the included wrap-around headphones are just fine, remaining on the neck and ears without bouncing all over the place, although their audio quality is only fair.

As my main usage for this is in my car (car manufacturers, take note - cd players need to know how to read mp3s!), the included car kit is nice, and helps justify the extra cost of this player. The small size and slim outline of the main unit means that I can keep the player inside the central armrest storage area, out of sight and not subject to slipping all over the place on sharp curves. Running on the car accessories power adapter also means I don't have to worry about battery consumption, though that seems to be just fine at about 8-10 hours per charge.

When running this player through either my car or my home stereo, the best feature of this player becomes obvious, its absolute clarity of music reproduction, absolutely perfect for classical music while also doing just as good a job on everything from Pink Floyd to Blink182. Some may find this clarity annoying, as every imperfection in the original recording becomes obvious - given the production quality of some modern day songs, this may show up more than you might think. The provided equalizer modes seem to be more than adequate, but you can create your own if feel the need.

In short, this is the player for those whose life just wouldn't be complete without having their music with them, regardless of where they are or what they are doing. And for this type of person, the relatively high price of this player is small compared to its net benefit.

25 great if u really want an mp3 cd player
first of all i would like to say this is a great product for anyone completely set on an mp3 cd player. If you are a first time digital audio buyer like i was plaease give a flash or hard drive player much more consideration. I thought this would probably be a better player than most because it could play cds. to get cds you just have to go thru the simple process of ripping. i bought an archos 10 gb mp3 player recorder and am so much more satisfied with it than my iriver. it has the useful feature of recording and more battery life. If you are worried about price or portability then please get a flash based player. you will be much more satisfied, but if you want an mp3 cd player this is the one to go with
26 Nice product
I'm very happy with my iMP-400, I was worried about some bad reviews about the battery life, but it has been working very good for me. In my first trip, the battery lasted 12 hours. In my second travel of 7 hours, the MP400 continued working well. I Only use it in my car, so, the headsets are not a problem for me. I don't know if the others are having problems reading discs with MP3 in directories. To the MP400 tooks like 1 minute to read a CD with 139 songs stored in different subfolders before beginning to play the music. For me, it's too much time. So I had to burn again my MP3s but without folders, and after pressing play, the MP400 immediately began to play the songs. That is the only "but".
27 Why this is the CD/MP3 player for you.
Heres the skinny. The Cdplayer is skinny, the LCD controller can play game(s), excellent radio frequency and sound compared to other CD/radio players,-10/+10 track skip to shorten time to switch ahead.

Basically its a very state of the art CD/MP3 player. To the people that complains about short battery life, did you know that the battery included are only about 1/3 charged? I used it all, charged it overnight, and it lasted the promising hours it said it will. As for damaged headphone included or any other broken part are impossible. The SlimX come in a BOX, unlike other CD players which usually come in some hard-plastic covering. You probably bought it used if you have damaged parts.

The SlimX delivers what it promise's. Great sound, great radio, great battery life, and great protection with antiskip. And for the people that say there players cannot work on the first try, or skips alot, try turning on the ROOT fucntion, if you dont know what that is or dont know how, then you probably dont even own this product.


28 Watch the headphones
I just opened up the iRiver package today, and was quite unhappy to see conventional headphones instead of the earbud headphones iRiver and Amazon both promise on their respective websites. Unclear whether I will be able to get these replaced free of charge or not, so buyer beware on this item. 1 star until this issue is resolved.
29 The good, the bad, but definitely never ugly
I just got my IMP-400 yesterday and was very pleasantly surprised by some things, sorely disappointed by others.

Good stuff:

-Remote was easy to use
-Came with nicer, upgraded, padded case instead of "a" velvet pouch I thought I'd be getting
-Pretty, thin, and light
-EXCELLENT shock protection--I used the ... thing as a drumstick against my desk for like a whole minute to test it and it literally did not skip at all
-one VERY notable thing is that the sound quality is very clear. For example, I understood every word in every song....some are songs that I've been listening to for years, and now I can finally understand what all the words are! I wasn't used to that kind of quality; I also heard new melodies and instruments in the background and they startled me! I wondered where those new sounds were coming from and they have always been there! I was just never able to hear them with any of my ...stereo equipment....yay iriver!
-you can program it to say your name every time you turn it on :)
-radio reception is great but....

Bad Stuff:

-..........you can't adjust equalizers while listening to the radio
-No Sennheiser earbuds in sight; just behind-the-head generics (but it turned out ok after all because I didn't really want earbuds anyway) though the bass on them is not very good
-lots of restrictive wires
-can't use the car kit cuz my car doesn't have a tape player :(

Overall I'm pretty happy with it and can't wait to burn a whole bunch of mp3 cds to play on it


30 Special fonts support is the best
For me, the special fonts support is the best feature of this player. In fact, this is the only MP3 player that you can purchase in North America to display 37 fonts, including Chinese characters. I am originally from Hong Kong and I have 10 GB collection of Chinese MP3 songs with Chinese titles and artists and this player will show them all. It will also show the other 36 languages as well.

A word of caution regarding the playback of recordable CD: use the slowest speed (1x or 2x) to record the CD. At higher speed, the player will start to skip and play at the middle of a song.


31 WARNING FALSE ADVERTISING!
My Imp 400 just arrived (I was the owner if the 350 before it broke) and after excitedly unwrapping the package I was shocked to find a pair of clunky generic "IRiver" wrap around headphones and NO SENHEISSER EAR BUDS. They practically advertise the ear buds more than the player and now they aren't including them? I feel so ripped off, I know the player is fantastic but I'm wrapping it up and sending it back simply due to the principle of the matter. Don't lie to the customer...
32 A Great CD/MP3 Player, but why pay $80.00 extra right now?
Before I give my review, why are people paying $80.00 for this product insead of getting the just as great SlimX iMP 350. There is actually no difference, except for the remote. On the 350, it uses 75 degree rotating dials on the top and bottom for navigation. It's no hassle to change music. On the 400, it uses a d-pad and center enter button. Both have there pros and cons, but each in it is equal. Now for my review. SlimX makes excellent products (minus any CD player less than the 350). This one is no exception. It has excellent sound quality, excellent battery life (around 12 hours on a charge), and has great skip protection. Also, how can you go wrong with being able to carry 6 hours of 128kbps music with you? If you want to spend a little more, go with a Nomad Zen (excellent bang for the buck). Other wise, if CD's are your thang, go with the SlimX 350 or 400.
33 What they don't tell you.
I'm not one to bash but I have a few things to say about the IMP-400 that others seem to be missing. First off I was very disappointed at the boot time. Why does a CD player have to boot? When you put a disk in you should be able to hit play and listen to your music. With this unit you put the disk in and hit play and the thing has to literally boot up. It has a little iriver splash screen which shows the iriver url then it gets to the play screen and finally is starts to play. Sure, call me impatient but I don't like the the 5-10 second wait time. I haven't actually timed it but it's too long for me. Let's talk about the most important thing when it comes to a player of music. That thing would be sound. The sound on the IMP-is great. Not perfect though. I'm your basic rocker but I listen to rap as well. I love a good bass hit. I like a bass hit that smashes you in the face and knocks the teeth down your throat. This thing hits like a little girl. I won't even listen to rap on it because the bass kick is just not there. Okay, the last thing I'm going to gripe over is the size. Sure it's a sweet little tiny unit but why? Cause they take everything and put it somewhere else that you have to attach to the thing by wires. You can't to squat without the remote. So that's one wire. The recharable batts will last you about 2 and a half regular audio CDs so what happens when you want to listen to longer sets of music and you don't have access to your AC adapter? (another wire) you need to hook up the external Batt. pack (another wire). Really the thing looks like a freak octopus when it's all attached. Speaking of things hanging by wires...the remote has a cool clip so you can clip it on to you so that you're attached as well. Only problem is the end you need to put pressure on to open the clip is on the other side of the buttons for the remote. So when you put pressure on it to open it you start hitting buttons with your finger/thumb. Pretty stupid move if you ask me. Put the thing so it's oppiste the screen. I'd rather have a thumbprint that I should wipe off than hit buttons and mess up my songs. As you can tell I'm pretty disappointed with this unit. I started to doubt it when I kept going to the website which said it was out in the US but nobody in the US seemed to have it until a month and a half later and it's still relatively hard to find if not a special order item so you have to wait anyway. I'm sending mine back. I picked up the Sony player. It has better bass and it plays quicker from the get go. It's not perfect either but it's better than the IMP-400 in my view.
34 It's a good player but design has drawbacks
I just purchased this player and while I think it is pretty good overall, I will share my thoughts as to the main pros of cons of it.

Pro
1. Nice styling, slim, light, doesn't feel cheap.
2. Good sound.
3. Upgradeable Firmware = Flexible, future proof machine.
4. Iriver Customer Service is good.

Cons
1. I do not like having all the readout on the remote. The remote gets tangled with the headphone cord and it becomes difficult to manage. While playing CD's from the unit without remote is possible, it is very limiting, you have no ability to control volume for one thing.
2. Remote design is flawed somewhat. While everyone has been been giving iriver kudos about the 4 line LCD and the new directional buttons, they have not mentioned which becomes immediately obvious once you buy this player. Whenever you go to clip remote on your belt or wherever, you inevitably end up hitting the song skip button. In order to avoid this you have to put player in "hold" mode each time you clip and unclip remote. This is kind of annoying and could have been solved by placing clip release or buttons on different sides of remote.
3. Price is a little high compared to other units (I know it will come down eventually). They could have left out car kit, and brought down msrp a little. Car kit is nice, but: a) not everyone has a car, and b) chances are, most people probably have a car kit from an older/other player.

I believe the carrying case has been redesigned for US release as it has a belt clip unlike the one in some early release pictures.


35 IRiver does it again
I have an IMP350 and now a 400 (yes, I admit it, I'm a gadget freak). The 350 was and is outstanding, but my biggest complaint with it was the remote, whose design is counterintuitive at best. IRiver has redesigned the remote for the 400 and now it's nearly perfect, easy to use without needing to check the manual every few minutes. I love both players but I recommend the 400 for the sake of the easy to use remote. The sound is outstanding on both players, and the upgradeable firmware is great. IRiver has really done it right...again...
36 best thing ever
I'ved waited about 5 months to get this baby.. and finally i got it.. at first i wanted the imp-350 but decided i could wait 1-2 months to get the imp-400. and it is just great. everything on it is spectacular.. I couldnt have asked for anything else.. it was kinda pricey but for something like this.. its a must BUY!!!
37 Another wonderful product from iRiver
I have just bought this mp3 player last month and I found it very wonderful with cool design. Going with its slim thickness, the smooth surface will attract you as the first look. Not like the 350 of iRiver, all of the control buttons are now on the remote control and you will feel a little nervous if you lost or make it broken. However, don't panic, you can have the replacement easily. iRiver has made it easier for you to replace the broken equipment.
The sound of its is wonderful, too. Not like in 350, now you have 9 presets of sound (one is your own define), and the volume is suitable for all of the people who like to listen to music in loud sound or soft sound.
The remote control is also the new jump of iRiver. You won't find anything easier to learn than with iRiver's. Everything, just need 1 hour to find out in the remote control.
You can listen to FM with the quality you can't imagine.
I suggest you buy this and this is the player you will not forget. The player you need for you active lifestyle.
38 Review of Iriver Imp 400 Slimx
Pros:
Iriver has come out with another amazing cd player. The Imp 400 has great features such as a 8 minute ESP, a wide 4 line backlit LCD remote, and much more. The slim design and the cover is wonderful. The color options are nice also. It also comes with Sennheiser MX300 earphones, which are much better than stock earphones. The rechargable NiMH are an added bonus, no more buying expensive batteries. The discharge and the overcharge features are good also.

Cons:
But the Imp 400 needs to work on the price. ... the price of the player is a bit expensive. For [a little] less you can get the Imp 350, It has the same features as the Imp 400 but the style is a bit worse. The weird rectangular battery shape is a downside. Not many stores in the USA sell these types of batteries.

Summary:
You should buy the Imp 400 if you want the latest style and features and dont care how much it costs. But if u want more bang for the buck buy the imp 350


39 A Great Alternative To the iPod!
I bought this mp3 player while in Canada. I have heard much about the slimX line of mp3 players and I am very pleased with their newest one. I have a pair of Sony MDRV700DJ headphones that run really well in addition to the supplied Sennheiser earbuds, the preamp on the player was able to do a moderately good job in powering my Sonys. The sound quality is excellent, with so many EQ options. However, I must warn that the remote is pretty confusing to use and requires a steep learning curve. I also think that it is pretty scary if you should lose the remote since the majority of the options are located on it. The CD player itself only has the basic play/forward/reverse/stop buttons and does not reveal the complexity of the SlimX. It's wonderful to know that when you buy this, you have the added benefit of playing new file formats as it comes along since the SlimX is firmware upgradeable, unlike many of the mp3 players out there. That was one of the main reasons I bought this player. Iriver did a really good job in recognizing the fact that what you listen with is just as important as what plays your music, the Sennheisers that come equipped are excellent and provide good bass response and clear treble. This is one of those mp3 players that you can simply buy and use forever and still get the most bang for the buck even after a year or two.
Definitely buy this!
40 It's the same old song....
I bought this player while I was in Korea on a trip to see a friend.

I had heard much about the qualities of Iriver and their mp3 players, and with their new IMP-400, I expected an even better product. Bear in mind that this machine definitely deserves 5 stars, IF AND ONLY IF the IMP-350 never existed. As a mp3 player that is over 70 dollars more than the 350 model, I don't think the player itself is any better in functionality and quality. What does separate it from the IMP-350 is the fact that the headphones are much more better and that the design of the lid is different. However, would I spend 70 dollars more? No, I would rather get the IMP-350 and a pair of nicer headphones such as a Sennheiser 570 or Grado SR60 that are far superior than the supplied Sennheiser earbud phones. I do have to give credit to Iriver for the battery-overcharge feature, however I have heard that the 350s do the same.

You might be asking why I didn't get the 350. Well, I got the 400 in Korea with American currency, which pretty much means i got the 400 for about the same price as the 350, so why not? =)

All in all, if you want the nicer-looking CD player, get the IMP-400. Bear in mind, it's only the looks. As far as functionality, it's the same as the IMP-350, which I think is the better value.
All of this is my opinion of course.
