I've used a pair the Sennheiser HD280 headphones for DJing for the past 7 years or so. They've been fantastic. Very comfortable and rather durable. I see a lot of folding headphones break at their hinges and these have never even cracked. The padding has begun to pull out and the sound quality is beginning to deteriorate, but I do beat the hell out of them and use them for hours nearly every day. I swear by Sennheiser. I have a pair of the HD439s at work and earbuds for the gym. All are very comfortable, sound fantastic, and are relatively cheap for their quality.
