I bought these to replace Shure E2c's. Fair enough, they cost more than double but the sound is so much more revealing. I no longer need to use any equalizer settings on my iRiver mp3 player, the bass is tight and the high end sounds are still there in abundance. I listen to all kinds from classical chill out to dance at the gym and they've not failed to impress. They are very comforatable to wear over extended times, so much that I forget I'm wearing them sometimes!
