Superb sound balance. Far from Bose or Monsters who are interested only in low at the expense of everything else. Here the bass is very dynamic, neat (I often listen electro) with a nice sound spectrum (for more instrumental compositions). Really I am very, very happy with this product. Be careful, the jack is fragile. By intensive use (jogging, metro, computer, travel), she abyss in six months. But I guess this is the hard reality for all listeners. Anyway it's high-end hardware at a great price.
