"Although I'm usually a fan of Sony headphones, I have to say that these are not some of their best.
There are quite a few headphones that emphasise bass notes. The good ones have a powerful bass that doesn't drown out other parts of the sound spectrum. The bass emphasis here really is overdone.
If you love bass, then these have some of the most powerful drivers around. If you're interested in vocals or subtle harmonics of higher notes, then forget these headphones."
