I read the specs, view reviews before I chose this headphone because I'm picky and I listen to music a lot; music is life, my girlfriend also said that. So I'm happy to pay more than a hundred bucks for a headphone. Overall, I think this one is ok. It's great if you listen to vocal, R&B, jazz, ... but for heavy bass music like dance, rock, or even classical, I don’t think its bass is good enough. Someone said its bass is concentrated not “blur”, I agree, but somehow it’s weak to me. I think I need an amplifier. I think about it.
