Sound signature is A shaped with the bass and treble recessed and the mids emphasized. I read everywhere they were flat sounding but to me they sound muffled with no bass at all. The M-100 Masters are not flat sounding but sound way better for less and are more comfortable. The ear pads on these are super thin and my ears hit the driver frame. Too expensive for what they offer. I returned mine.

very good quality for the money u pay . so good value
