Yet despite all this, I am proud to say that they still sound as good as the day I bought them. These things last forever - It never ceases to amaze me. Well done, Koss. Well done.
I used it between my computer and my stereo system the whole time on a near daily basis of changing between the two. The plug withstood it all. I've yanked the cord (which is about 8-feet long), dropped the headset, tossed the headset while plugged in, crushed the headset under everything from books to a computer (long story on that one), and on more occasions than I can count, fallen asleep and rolled on top of them. They took all the punishment and kept going.
The worst damage that occured was that a piece of the plastic over the Logo oval and below the slider stop on the earpiece (you can see it in the picture) on the inside of the headband broke off after 2 years of me overstretching the headset, and that was easily resolved by replacing the plastic piece that broke off back in place and wrapping the area with some black electrical tape.
The sound quality is exceptional. You can hear the highs and lows of every note in a song and clearly understand every part of a conversation in a game or video. And once they are on your head, outside sounds are gone. Someone could crash their car into your house and you wouldn't hear it.
It finally broke after the wiring in the right earpiece couldn't take my abuse anymore, and even then I was able to get it to work on-and-off for a month after that before it finally said no more.
It survived all that and I only paid $25 for it. All in all this headphone is tank-like in the long run. I'm planning to buy two more. It's a great headset and worth every cent considering how long it lasts.
