I'm not an audio fanatics, have no references in this price range, so I can just claim - so awesome and personally I've never heard my music :) Super shield outside world, powerful bass, no unpleasant heights, still sounds very good even at low volumes. Cables are nice and thick, give the impression that they are not so easily go wrong, as in many other - even entangled not so easy. I'll use the supplied foam pads, sound exactly the same as the silicone parts for me, just stay much better in the ear. Can I strongly recommend!
