Y qué podría decir que no se haya ya dicho de unos Hyper X, la calidad de audio es asombrosa, eso sí, el volumen máximo deja un poco que desear. The only thing is that you have to keep it plugged in at all times. 40V DC, one bar pulled 1. Rockport aint what it used to be. Sound Quality - Rich, spacious and immersive, maybe skewed slightly more toward treble than bass but not to the point where I feel I need to EQ the output from my phone. Worse still, the mic and the isolation filter aren’t even compatible either! The sound is good and the headset is both comfortable and noise isolating. Sad, Amazon please protect our money better with tighter QUALITY CONTROL, 5 so I had hard time deciding size but I decided to go with 7 and they fit good. I like the style and though I have plenty of room in the sandal, my foot feels quite secure.
