Lightweight and comfortable headset. Very good placement of the ear. Hold perfectly. ON / OFF handy Clear sound quality and without reproach. Association with very simple phone. Charger Micro USB / USB with USB Port Replicator + USB adapter / 12V cigarette lighter. It's all good except the greeting at power which is in English. Not easy for francophones and shame as the remaining range is announced which is very convenient to use. Especially that autonomy is average (max 6 hours from a full charge). Loaded in 1h30.
