A Bluetooth headset of good quality that is comfortable to wear and warm listening. The Bluetooth connection with my mobile phone or my Iphone Android tablet took place without any problems and very simply. The sound quality of the headphones is undeniable and musical pieces are faithfully rendered. We like listening without the constraint of the wire. The controls on the headphones are easily accessible and reactive. The helmet is nice and long one can listen without any fatigue or gene. The headset is supplied with a jack cable you also have the opportunity to connect to devices that do not have Bluetooth, but I find the cable a little too short. Charging the headset is very simple USB cable connected to your computer or smartphone charger. I regret that the helmet does not come with a pouch for transport.
PS: after several months of use I provides additional information on this helmet. I take it one star because the daily use it has a very annoying spot. When I'm not wearing the helmet I put in my bag protected by a pocket, but it regularly turns one and so I found it where discharged with very low charge remaining. The principle of switching on and off by long presses on the headset is not very relevant to the use, a physical button on-off with blocking would be preferable.
