I have a feeling that in this Headset simply the high places were turned up and the middle and bass out. He makes a clear sound, which in my opinion but at the expense of depth. For Metal I feel it to be inappropriate. Classical it is clear, but also because I lack the deep bass. Clean music (eg non-distorted guitars and vocals or piano and choir) are differentiated and quite round.
For Pop certainly suitable, but for me, unfortunately, he does not fulfill the real purpose. Too bad, a bad buy.
