Good sound already just with the headset and stereo already very satisfactory when we add the earpiece provides (it connects directly to the headset). Good quality reception and transmission of calls even if the wind means yet (but there are few bluetooth headsets that support the sound of wind burst). Good ergonomics, not too heavy, very proper communication autonomy (tested more than 2 hours in places where it goes badly). Possibility to get vocally or by pressing the switch on the headset. Redial last dialed number (two presses of the headset button) and listening to music (1 support only). Indicator light payload when connected and when charging is complete the light turns blue. Flashing red and beep when the load becomes too low. Everything ok after more than 2 months of use. Short to 16.99 Euros (50% discount), who says better? A small flat perhaps with the resistance of the ear at the attachment to the headset itself, it has cracked after 2 months (but hey, let's be honest, I'm not an example of delicacy with 'Bluetooth', they have a hard life because I'm using really all the time: I do not even support it, since I discovered the bluetooth, holding a phone in his hand). I'll just have to resupply me in the ear.
