Your recommendations for cost-effective and musical sounding headphones?


This is an honest attempt to restart what was a good conversation earlier that for some reason was dismantled.

My votes are, of course, for headphones I own and enjoy, those being (in no particular order):

Sennheiser HD600
Sennheiser Momentum on ear
Grado SR225e
AKG K240

I've used Grado RS 2, AKG 702's, 240's and Senn 600, as well as many others. IMO, Hifiman 400's kills all of them and have been the biggest and most significant upgrade in sound that I have experienced in a long time.
Great comments here. I need to hear HiFi Man and Audeze to get a sense of what alternate designs contribute to headphone listening. Recently bought a JDS O2 amp for my Senn Momentums and had no idea they could sound this good. Clearly amplification also makes a difference in perceived headphone quality.
