Had them about 8 years, and they are still good as new and sound incredible. Sennheiser HD-580 headphones. They are super comfy, have open ear design to allow you to still hear conversation/sounds assuming you are listening at moderate levels. They will get loud and have great bass response. They've been replaced with the HD 600 model, in which really only introduced a metal outside grill taht gave better sound resonnance according to them. I acctually got the metal ones off ebay and replaced the plastic ones on my 580's and I can't really tell a difference, but they look better
Well worth the money IMO. Use em for music, gaming, tuning out co-workers before i worked from home, whatever you want to listen to.
