I found the sound quality of these headphones to be very disappointing (Matador). I'm surprised that they get such good reviews. The quality LOOKs good but all I got was muddy and indistinct mid-frequencies and almost no highs. If you want bass, these might be okay but they offer very little else. Having paid 50 Euros plus postage for them, I ended up giving mine away. Possible the worst headphones I've ever owned.
