Sennheiser PXC 310 or the Audio technica ATH m50's
I am deciding between what headphones to get, the Sennheiser PXC 310's or the Audio Technica ATH m50's, or possibly the Denon AH-NC732 's. I do some mixing on my computer and own a synthesizer and yamaha p80 that are both attached to my PA system so i'll probably be using them for that also, but probably 60 percent of what ill be using it for is listening to music. So with that in mind i was wondering which one has the best sound and would be best for what i would use it for? Also how long is the ATH m50's coiled cord coiled up?
