The sound and wireless noise because I was looking for, to the extent that I often travel are relatively good (I'm not a music lover), although less effective (6/10) that the bose quiet comfort 15 (9 / 10) (I tried 2 during a transatlantic voyage AA)
For cons, the mechanics are designed deplorably since a shoulder of less than a millimeter plastic keeps the joint which is used to put the helmet dish or finely orient parallel to the helmet ears .. after the coup qques months of daily use, this one dropped making it unusable helmet ... shame for a product has more than 150 euros ...
software, impossible question to activate the high sound quality headset + microphone, making the use painful (crachotis, half duplex cut) in this mode ... pure headset is very good, even if the difference its power between the wire mode and Bluetooth mode is annoying (bluetooth mode, the sound has to be continually background ...)
short I am really disappointed by a product that satisfied me despite some imperfections which unfortunately wears out very quickly and breaks because of a major design flaw.
