Product order on amazon and recently received very quickly. The big snag for this helmet is the damn instructions in English which, for people like me, are dipping almost nothing in English, has left me perplexed when the bluetooth startup headset. Moults after research on the net, I finally fell on a leaflet in french. So for the headset switched on, it is necessary to ensure that already 3eres for use, the battery is fully charged, then press the big main button, the LED turns blue, leave your finger on the button (not the lacher above) until the light turns red and eventually flash. And here you will just have to find your helmet ds your iphone, ipad, ... Honestly, I almost bring the amazon was because I thought that my helmet was defective but thanks to these explanations, it works perfectly, rendering sound is very good.
