Very good headphones to correct price. Recognized as a helmet beats on my htc sensation xe. By cons like all good level of bass beats headphones to drop the amp via the drive if you are not a fan, the midrange and treble are decent égaement. The son are light and fine cuisine which is rare. Big plus, should not eat much because the average volume level are super efficient while with other headphones I put in 4/5 for the same volume.
