Lightweight, well-made with excellent sound response. I love these for running: they block outside noise quite well so the volume from my mp3 can stay low, and the sound they produce is full and balanced. Depending on my mood I listen to punk or classical, and both sound great. Recommended.

These headphones are awesome, lots of bass. I like the kind that seal in your ear, these do that. I like these because they don't get as dirty as the other foam ones Koss sells. Lifetime warranty, which I've executed many times with another set. $6 check for shipping and you get a new or refurbished pair.

These earbuds sound really good with my sony mp3 walkman. The sound is very clear and they have good bass. They are also quite comfortable in my ears and they fit nice. The best of all is that the cable, which is not the typical plastic one that breaks after a while, this one is cloth-covered, so it is made to last long time!
I was looking for this particular feature since all my previous earbuds always have problems with the cable that got broken. Not a problem anymore!!!
I would definitely recomend these earbuds if you want something of good quality and that is going to last. In addition Koss has the lifetime warranty no-question asked. great!
