The headset is charged using a micro USB B connector, standard cables easy to replace (ç BIG advantage over other brands like Jabra which use proprietary cables virtually irreplaceable if lost). The battery has a phenomenal life. A switch allows you to completely disconnect the device, preventing an unintentional discharge standby.
The device can store pairing with two GSM (and / or PC).
This headset offers different levels of pre-set volume, the volume button cycle through presets in one direction only (ascending) and returns to the minimum after reaching the maximum. The main button is used to reconnect the device to the last active source when the Bluetooth connection is lost (too large distance from the source connected, for example), minimizing the time to reconnect. The range is large enough to provide various uses without fear of disconnection.
Voice announcements (in English, female voice) allow to know among others when the device connects / disconnects to a device, the charge level of the battery (ad level during power up alerts when the battery becomes weak), which device is connected (from the two stored), very convenient!
The sound quality in the headset is very acceptable and the recording quality is impeccable.
Tip: In Windows 7 and do not use BlueSoleil, I had all the misery in the world to operate the device properly through this system, while the Windows native support for Bluetooth devices work A WONDER with this headset.
