The sound is pure, perfectly respecting the bass and treble whatever the style of music. In testing, I tried the Folk, classical and hard rock: the tones are returned. It is given for a battery life of 20 hours, which allows time to recharge the night quietly This load on any charger with a USB port, be it a PC or a Smartphone charger 5 volts. For my part, I lai loaded on the USB HUB 10 ports that team my computer. It works by Bluetooth 3.0, but is backward compatible with versions 2.0 and 1.1 earlier.
In addition BE a finely crafted stereo headphones: it can also serve as a telephone answering machine. Indeed, I does not like in helmets is that I nentends not ring my mobile! With it, you have a small beep announcing an incoming call. Because you thought lappairé with your smartphone, press the on / off button and answer the caller without further formalities. During the time of the call the music is muted and will resume automatically once you hang up.
In summary, a great product with a dual purpose for joining lutile to the pleasant. His doreilles pads are a treat to have the helmet that allows for a long time without feeling pressurized. Headphones are also adjustable, allowing easy storage unlike conventional helmets. If you do not have Bluetooth you in the package accompanying the headset audio Jack 3.5mm wire to connect it to your device.
