Review on HJC Helmets Smart 20B Unit Street Motorcycle Helmet Accessories - Black/One Size by Luis Green

Mainly needed for music, GPS and phone calls, not a real bike communicator. Installing it on my module was pretty easy. Setting up Bluetooth on your phone is easy. Sound quality and volume are better than I expected. Setting up the FM radio was easy. The phone test went very well. The boom mic is a bit finicky in position once the front panel is closed, but that's not surprising. The side controls are easy to use with gloved hands.
