Summary: Umm well, I wouldn't recommend buying this for anything more than $20. Your paying for the frame because the sound is equal to toughs cheap delta airline headphones that they give passengers for free. So wait for them to be on sale.
Pros: Nice sturdy frame, not heavy at all to me. Alittle tight around the head but not a con in my book someone might like it alittle tight around the head.
Cons: Sound, usually the big reason why someone gets a pair of headphones. The quality of that sound matters, I am betting KOSS went with a dirt cheep speakers in the headphones. (sound being as bad sound quality is a instant loss of 3 eggs, since what makes headphones great is quality of sound.)
Summary: I bought these headphones on a few recommendations and the fact that I could get them for 30% off. They sound as I expected them to sound. Koss headphones usually have great sound. I wasn't expecting too much, since these were priced in the lower range.
Summary: We use these headphones in the computer labs at my school district. (so my experience is based on over 200 of these headphones) They hold up very well to the day to day use (and sometimes, abuse) that elementary age children throw at them.
Summary: They are definitely worth the price that they cost. They aren't DJ quality, but hey these are pretty close. When I practice my vocal parts (Metal singer) for my band these are what I wear.
Pros: I have had these since November of 2010 These are amazing. I wear them all the time especially at school. I find them comfortable, and the sound Quality is fantastic. The Cord is a nicely coiled and the fact that it can stretch is helpful. I love these so much.
Cons: They weren't heavy to me like other customers complain but they were tight at first However they loosened up. They don't have the best sound cancelling, I know they weren't meant to sound cancel but it was a nice thought. They do cancel out some noise. Also due to my excessive wearing, which was ...
Summary: Wore them for about 4 hours playing Portal 2.
Pros: Seem to be very sturdy. Good sound quality. Strong cord.
Cons: The ear pieces are too small for my ears, the headband is very stiff and has no padding despite it being huge and looking like it is padded in the pictures. Probably the least comfortable headphones I've ever owned, but still wearable.
Summary: If you're getting these for JUST listening, GREAT GET THEM! But if you're going to be recording or DJ'ing where you need to have one ear listening to headphones and one ear listening to a monitor, you might want to select a collapsable pair.
Pros: Great construction. Excellent sound. Does not hurt my head or ears. Comes with 1/4" stereo adapter. Muffles outside sound great and cannot be heard by others in the room. Wonderful wonderful wonderful
Cons: design... They do not collapse like you'd think they would. You cannot choose to listen to only 1 earpiece without bending the head band unit.
