A great mobile headset with microphone.

The materials used are of good quality and gives a classy and solid appearance. It is not too heavy and leatherette earpieces are comfortable.
Many features torque when the headset with a phone. The buttons are well placed and the use is simple. The scope of the connection is very good in my apartment of 55 sqm, no decline in quality even when I'm away from the Bluetooth transmitter.
It is possible to pair the headset with two devices.
Sound quality aside, as it is inside, I do not use anti-noise. When on the sound quality is less pleasant to my ears.
Without noise the bass is deep. Acute go well. No breath when the volume is low or there is no sound. No interference with other waves (wireless, microwave ...).
Update firmeware and language customization possible messages via the computer and the supplied USB cable.
The battery life is impressive

Conclusion: I do not regret my purchase, it is a very good mobile helmet which replaces my old HiFi headset without wire whp562 Thomson.
The delivery was very quick.
