Incredible!
I have problems with headphones.

Either, they break very very quickly, or (in the case of ear-bud type headphones) fall out of my 'differently designed' ears as soon as I put them in. These Koss ones however are a different matter: - they fit and grip into my ears fantastically well and are actually indestructible (so far at least). The sound quality is great too.

If I do manage to finally destroy them, I will definitely be replacing like for like.

Great stuff!

=/
As soon as i recieved these headphones i noticed they were huge, although that has so far been the only problem. They have superb sound quality and a very comfortable fit and i would definatly recommend them. Only downside is i feel like they stick way to far out from ear.

Dire
After reading the reviews here, I opted for these to replace a pair of "gym in ears" (JVC marshmallows) that had seen the inside of a washing machine.
A poor choice.
The housing is rather uncomfortable, if you find the iPod ones uncomfortable these will also not suit. The sound is poor, flabby bass overwhelms the muted washed out mids and the highs are non-existent.
I tried running them in for 48 hours, they were still no better.
Replaced them with the Sennheiser CX300's, which are rather more expensive, but infinitely better.
