Sony MDR-G74SL

Pros: Sound is Perfect

Cons: large which may make you sweatew

Summary: These have to be the best sounding headphones I've ever had (and I've had many). The bass is awesome and the highs are just perfect. The 20" cord is just perfect to connect to my Ipod strapped to my arm. It's like they designed it for running. The only thing I can say which might be considered a negative is that they fit over the ear quite a bit so you may sweat alot while exercising. that's the only thing I can think of though. People say they're fragile but I fold them every day and have not had a problem in about two months. I would have loved it if they had an inline volume control but I picked one up at Radio Shack for $5 anyway. Buy these, you'll love them.
