Hi, just wanted some advice. I listen to hip hop music and I'm looking for a good quality pair of headphones. Searching in web, I came across 3 headphones: AKG K242 HD; AKG K272 HD; AKG K240 MKII. I've understood that K272 are "closed", while the other two are semi-open, but in terms of quality of sound which is the best?!? Specifications about impedence,etc.. seem similar in the three models. Can you help me?? If you know some model of headphones to suggest to me, please tell me!! thank you so much
