With this very simple device (1 connector to charge the headset via USB to the computer, 1 headset, spare ear, and that's all), my comfort has increased considerably.
Installation is very simple: you press the "on" button, and you can pair the device with the phone (I tried it with a Samsung Galaxy 5 with no problem). The helmet is put (the arch starts at the back of the head, not on the head), and it works. I understand perfectly well my interlocutors and they did not notice any change in the quality of sound when I switched from my landline to my paired headset on my cell phone. Side stability as I spend my sitting motionless calls, the headset remains stalled, I have nothing to regret. It is even extremely comfortable thanks to its lightness.
I put only 4 stars and not 5 because I regret, once again, there is no device with the charger operating on an electrical outlet.
