These are so easy to listen to for a long time.   Comfortable, not harsh.   Superb mids.   I can hear things on these headphones that I never could on my Sony MDRs.     They need amping though (and playing loud) ..or they are a bit too mild mannered.

I really like these... but I like good clear high frequencies.   Lots of detail in the music.   The pads rot off over time (faux leather) but you can replace them with pads meant for an alternate brand (mine are now velvet).   I would not be without them.   They have stood the test of time.
