Review on Bone Conduction Motorcycle Helmet Bluetooth Headset with Super Bass, IP68 Waterproof Speakers for Helmet, 10hrs Play Time, Ski Helmet Speakers with Separate Microphone by David Turner

This is not bone conduction. The body just vibrates. I was a little disappointed. Call quality is good, although the music (the main reason I bought it) is just ok. 3/10 mononucleosis. Muted. If you're looking for Bluetooth speakers for your helmet to play great-sounding stereo music while you ride, this isn't for you. If you use a full face shield, hide the microphone in the helmet. Otherwise you will lose it. I haven't tried it while driving. So I don't know what kind of sound is on the track at speed.
