Very good product, which perfectly fits the description made. Works great with iPhone 4S. Connection in seconds, without the fuss. Lightweight, comfortable and with great autonomy. The information (battery level, connection to devices, O / I) said in oreillete are all in English. In terms of the multipoint connection, it works well too, no problem. On appeal, my interlocutors did not report anything to me, they heard clear to me (I have not yet tried out with the wind) and me too. Several diponibles orders directly on oreillete (volume, answer / hang up a call, last number redial, voice control). With the iPhone 4S, Siri voice control triggers but only downside I found is that Siri can not leave by the same button (on the remote control as original headphones), you must leave the phone. Battery level indicator directly on the iPhone. No support music (regardless of the phone). Overall so this is a very good product quality assured (good brand in this area) and without excessive price. Good investment.
