    funcionamiento correcto, trae muchas piezas para adaptar sujeción al casco. lo mejor sonido increíble sin ruidos de fondo incluso a más de 130km en casco integral. Usado para comunicar con mi pareja en la misma moto por lo que no se ha probado en distancia. recomiendo si quieres viajar acompañado .

    From the moment of order and until receipt-12 days (respect for speed). Norms headset. With his task copes. Direct visibility on the track-up to 200 meters, further interference appears. On the helmet Nolan became without problems. On the BLD helmet I had to make a self-made presser plate from stainless steel 1,5mm (in the photo it is visible). Respect to the seller-5 stars.

    After a month of testing I am very satisfied with this
    Intercom. I tested it on 1200 km with my wife and
    We’re delighted. We took the rain and at first glance it did not alter the intercom.
    When installing a headphone was failing certainly a welding problem. After two exchanges via mail we were sent for free a new earphone that works very well. The merchant is super responsive and accommodating. I recommend this product sold by a super Walker. Only positive. Thank you

    Article conforms to the description and arrived quickly. Little trouble with one of the microphone but lexin sends it back to me, so I am satisfied with the contact with the seller and eager to receive it to use the device without restriction. First intercoms so no point of comparison nevertheless I recommend this purchase and this seller.

    It’s a big surprise! <2en> received in record time and at a broken price compared to Am… the editing was not tedious. It’s simple. <2en> I tried it in open or closed headset configuration at different speeds… from 40 km/h to 130 km/h same observation for my interlocutor to whom I phoned: great sound! <2en> at the level of music there is enough power. <2en> I have not used the Intercom functions yet. <2en> one regret I did not manage to activate Siri! <2en> the device must be in standby says the instructions. Is that to say? <2en> good in conclusion an excellent value for money. I recommend

But do they already so tested and the quality is super and go also super far. Also have also now for my 2 small children ordered. Is super for Our Vespa rides.

  25. J***v

    Everything is perfect. The package, the unit, the quality of sound is perfect for the price range and not only. They are loud enough. Soon I will test the connection with other make communicator. For now for me there is one issue and that is the clip with which you mount the device to the helmet it is not designed very well. I mean that it is strong but the contact area is so small and the communicator can be fixed very strong.

    Soon will write another feedback with pictures.
