Summary: Use them a lot. My comport is next to the living room and my wife has the TV on and I listen to my jazz music with headphones on for hours and they do not hurt my ears at all with very good stereo. And I am ordering a new set for my TV in the den.
Summary: Picked these up to use at the gym. WOW!! Could not believe the full range of sound that comes out of them. Great high and low end. Light weight to wear. All plastic but seem pretty sturdy. For the price, absolutely cannot beat the sound quality.
Summary: I love these headphones. They work well and the price is great. These replaced another pair I bought 8 years ago and used extensively. The sound quality is good and they stand up to hard wear (they routinely get stuck in the bottom of the bag under my computer and still keep right on going).
Summary: I've always loved Koss headphones! These are no exception. I wear a hearing aid, and these fit nicely over that and do not cause any feed back. They are comfortable, and have a great sound. Great value as well, if they need replaced, it's not going to set you back much.
