Send Lightning !!!

Commissioned in the early afternoon; received at noon next day delivery at incredible speed !!!
Very good product, excellent, very easy to operate, this is still the same principle as all Bluetooth devices (long press on the button "Power" up to alternating red lights / blue) because the instructions are only in English but extrement simple to understand.
Several tips offered with and Mini USB cable for charging on pc.
Autonomy is very good (about 7 hours), the load fast enough (big time when the red light remains on while charging), sound like I have told impeccable with good bass, volume + button and - that it is not used in general, since the increases from his phone or tablet.

Works great as a Bluetooth headset during a call, the microphone does its job, the conversation is clear, we mean very well.

The thread that makes connection between the atria allows to press s something solid without s crush the skull against this part, as a neckband, especially when one takes this helmet for sports, such as where the muscu the one is regularly lying on a bench.

I fully recommend this product!
