Out of the headphones you have used / own, If you could keep 3 headphones that you would have to keep forever and never buy any more headphones, Which would you keep?
Mine would be (out of headphones I have owned) :
Shure SRH 1540 - Very good all rounders, comfortable, sound good with everything.
Denon D2000 - Good bass, very good for electronic music.
Sennheiser HD650 - The midrange and smooth sound is a good combination with the other...
