Summary: They are so comfortable, sometimes I walk off with the head set still on my head, and it yanks the 3.5mm cable out of the audio jack. But when you think about it, that is really more of a pro than a con.
Pros: These things have amazing base, I have had these for 5 months now, and they are still going strong! I often forget they are on my head because they are so comfortable, and the cable is plenty long. For the price, you absolutely cannot beat these headphones!
Summary: I got these when they were on sale for about 12 bucks, but they'd be a good deal even at 25. One thing that threw me off was it came pre-equipped with an amp jack adapter, took me a minute to figure out that it came off to expose its actual PC jack.
Pros: it fits nicely, pretty comfortable, even if you wear glasses. I use these at my work PC and I can wear them all day.
