Upon first listen to these headphones is assured slap: the sound is excellent, neither too round nor too aggressive, just perfectly balanced. You are good to regret all your badly encoded MP3s. The sound is really excellent precision. In addition, insulation is very good and the box that contains earphones offers a wide selection tips that adapt well to the ears (in doubles, just to complete the table). These headphones are a bit heavier than the competition, but nothing problematic. All that exudes high quality manufacturing in addition to the excellent sound quality ... I do not see what's missing in this luxury box. It is simply excellent! The price is perfectly justified, for sure ...
