I recently needed to resolve the problem of not being able to hear music while playing drums. I play along to the music so I need to have the right balance of the music and the drums. A drummer in the US recommended Sony MDR-7506 headphones which I bought from http://www.totalaudio.co.uk/Phones/phones.htm. I'm very happy with them. My MP3 walkman playing at full volume is clear and undistorted and the quality insulation allows some volume of drums through but not enough to overwhelm the in-ear music. Recommended.
