500M BIM Motorcycle Helmet with bluetooth Function Headset Intercom Interphone
Bought 2 of these for skiing, they are really great and clear, however max range is 150M which is fine for on the piste and chairlifts.(not 500m claimed) At longer range there is a noticeable buzzing sound, but overall really make skiing very enjoyable as its so easy to keep in touch, hands free, no call charges either.
Не плохая альтернатива блютуз.Звук на уровне,правда липучки держат не очень.Подумываю заказать ещё!
Well... 500m its optimistic, but for that prise its a very good offer
