For the money, it is very good both in terms of fitting inside the helmet and battery life. I charge it twice a week, working a 6-day, 7-hour delivery schedule.

Very good. Sound is good in the machine and with an open helmet. I just got it of course, time will tell how long it will last.

The music plays quite satisfactorily, but during calls, the sound in the earpiece is reduced and you can hardly hear anything, and the microphone is disappointing. You can't communicate with anything. ONLY FOR MUSIC

It does not answer calls from Viber, it does not fit in the helmet, it requires sockets or to make them, it requires earplugs because it is loud
