1 They break
Great sound. Fantastic sound. Then one day, you'll try to adjust them, and they'll just shear off at the post. Not worth the money.
2 Nice Sound, Questionable Construction
I am not a headphone expert, but these headphones sound great when listening to my rock and classical mp3's. They are crisp, with tight bass. Ear fatigue is minimal for me when I have them on at low levels all day at work.
I question the "Collapsible" claim in the headphone title. The ear pieces swivel 90 degrees, but that's about it. The headband part does not fold, bend, or move otherwise. These may be too bulky if you need to stuff them in a laptop bag.
One of the ear pieces on my set just broke off after owning them for about 2 months. I was quite frustrated by this, but Koss offers a lifetime warranty, so I'll be sending them in for an exchange.
3 Very Poor Craftsmanship
I bought my KOSS PRO3AA headphones at an electronics store. They last about 2 months, then the right headphone attachment broke while I was putting them on. They were not abused, and after much closer inspection I could see that the swivel is a very thin part, made of plastic, and had broken under normal usage.
While the sound in these are great, they only lasted 2 months. That isn't very long for $50 headphones. Koss wants me to ship them to their repair center at my expense, and pay for the return shipping costs as well. I am just going to spend that $10+ on something else more durable.
