Enjoy rich, accurate sound through your portable CD or MP3 player using the Koss KSC75 on-the-go headphones. Designed for people who want a lightweight listening solution without sacrificing audio quality, the phones employ a pair of sport clips to fit neatly around each ear, thus eliminating the constraints of conventional headbands. As a result, listeners can wear the phones--which weigh a mere 1.5 ounces--without disturbing their carefully coifed hairdos. When not in use, the headphones store compactly in a backpack or purse without taking up unnecessary space. Meanwhile, the phones produce terrific sound through their titanium-coated high-polymer drivers, which are built for maximum precision, as are the bass-boosting neodymium iron boron magnets. Their combined efforts generate a noteworthy 15 Hz to 25 kHz frequency response. Additional features include oxygen-free copper voice coils within the cord that protect the signal clarity; a straight, dual-entry 4-foot cable; and a 3.5 mm plug.

1 Great headphones that don't break the bank
I bought these to replace my Koss KSC-35. The first thing I noticed about the KSC-75 is that the earclips are much more durable than the KSC-35. The KSC-35 earclips were made of plastic which would eeventually break off. The KSC-75's earclips are made with both metal and plastic which is more sturdy. The sound on the KSC-75 may not be as good as the KSC-35, but they are better than the cheap earbuds that uses comes with a digital audio player. The earclips feel comfortable even after several hours of use. The cord is long so you don't have to worry about it not reaching your mp3 player in your pocket.
2 The best headphones under $50
Looking for a replacement for iPod's earbuds and after extensive research I found the KSC-75s. With the same titanium coated drivers as the KSC-35, KSC-50 and KSC-55 they deliver a detailed and balanced sound. The earclips are very comfortable and IMO they look great. For less than $15 these headphones are a steal. Forget much-hyped brands such as Sony and replace your awful earbuds too.
3 another solid Koss phone
The KSC-75 is the latest edition of the popular and good-performing Koss KSC series. All of these models, the 35, 50, 55 and now 75 are based on the same 60-ohm drivers (also used in the Porta-Pro and KTX-Pro phones). The original model, the 35, is regarded as the standard by which all cheap, portable headphones are compared. The original 35 was a black, clip-on model, built to be very shallow and to fit closely on the ears. It was a fairly nasty-looking, uncomfortable piece, and frequently had problems with its thin foam padding tearing. It was updated to the 50 and 55 models, more "modern" looking silver clip-ons and behind-the-head models. The problem with these was they were significantly heavier, and didn't fit so snugly to the ears. Thus, even though the drivers were the same, the sound suffered a bit because of the loose fit.
The 75 moves a bit closer to the original 35. It is a shallower phone, although still not quite as much so as the 35. It does tend to fit snugly to the ear, which helps make the sound a bit fuller. They are nice and light and are very comfortable. The clip is a different design, it doesn't snap into place like the orignal 35 or hinge like the 50. It simply bends around the ear, leading to two problems with this design. The durability of the thin guage wire could be a problem. Secondly, the headphone cup tends to snap off of the clip when fitting the headphone to the ear. It simply snaps back into place again, but its a nuisance. Once properly placed, which takes a little practice, the sound is typical Koss KSC. The sound is pleasant and full, reasonably detailed and transparent. There is roll-off at both frequency extremes, although this can easily be corrected if your player has an equalizer. Even without equalization, though, the sound is quite good. Despite the 60-ohm rating, the 75's are reasonably easy for low power portables to drive. On an absolute scale or compared to the better $50 phones, such as the Sennheiser HD-497, the Koss KSC-75's don't stand out, but for a price of less than $15, these are outstanding. They easily trump any of the included phones or buds with portable players and are easy to transport, due to their light weight and small size. Another excellent, cheap Koss phone.
Update: With more use, I've become more favorably impressed with this phone. Its sound seems to have opened up with more break in. It now is very transparent with a rich, deailed sound - unbelievable for this price range. After a few uses, one gets the earclips adjusted properly to where they go on almost instantly and stay put and are very comforatble. This should minimize the amount of adjustment needed and prolong the life of the clip. Still, the headphone cups occasionally snap off of the clips even during normal handling. But in all, these are an incredible bargain. I would now rate these a five star phone.
4 Lives up to the hype!
I researched headphones a lot before buying these. The line of Koss phones with the portapro driver's (including the KSC35/50/75) consistantly get excellent reviews. So I was glad to find them here for an great price. I've heard that these phones sounds as good or better than anything under fifty-bucks. I don't have enough experience with a range of phones to say this for sure, but from my limited experience I believe it.
SOUND: excellent, straight out of the box. Best sounding pair of phones I own and only fifteen-bucks!? Nice range, clear tones, and great (but not overly bloated) bass.
My one complaint about sound is that it leaks a lot! Because these are open design they will let outside noise in, and they will share your music with your neighbors. So maybe not as appropriate for noisy buses, subway, airplane, or in close crowds who don't share your music taste.
COMFORT: surprisingly nice! They were easy to put on the very first time and I can hardly tell I'm wearing anything. One nice improvement over previous Koss clip-on models is that the clip is adjustable. It's a metal wire covered in comfy rubber. You can easily bend the wire to adjust the clip to fit perfectly on your ear. You can make them hang loosely, or tighten them up for punchier bass, and so they stay snug when exercising.
LOOKS: not the best, but better than previous Koss clip-on designs. They look like an updated KSC35--silver and more curvy.
OVERALL: Excellent set of headphones that are UNDERPRICED for their value!
5 Misleading title
These aren't really foldable headphones...just over-the-ear types. I will say that the sound quality from these is pretty nice for running, the gym, etc., but not if you want to drown out noise on an airplane or subway. Also, they fit very well over the ear, but some people may have a little trouble the first time they put them on, as the new clips are like eyeglass arms, but tighter.
Overall, Koss has delivered yet another quality product. I've purchased nothing but Koss headphones (except for those free buds that come with most everything nowadays), and will continue with their products in the future.
