it's great! i don't know why i bought this so late! it works, easy connect bluetooth. Sound is ok, not that loud, louder would be perfect.over 100km/pu with hearing protection in my ears and speakers in loudest, i don't hear good. around 50kmpu it's ok. haven't made phone calls. there is a control on the microphone, but with gloves on you can't feel them.
works ok until now... the only issue is that the manual is in Chinese!
