Recieved these just now and hooked them up to my computers amplified speakers (Altec Lansing} And I was thoroughlly impressed.. These phones have so much bass in them, I can feel them shaking on my head when hitting low notes.. I'm unsure of how much they "color the music", but for $13.00+change they are outstanding!!! They can be played rather loudly before distorting, which is what you need when you buy a set of phones for a DJ application.....One of the best buys I have ever seen...You can buy a set at Wally-world, and pay twice to three times more and they'll not be this good..
