Review on HJC Smart 10B Unit Motorcycle Helmet Accessories - Black, One Size by Jason Clemons

These devices easily integrate with HJC helmets. Bought 2 to be able to hear the GPS and communicate with my wife while we drive. The instructions aren't very detailed, but a couple of YouTube videos answered all the questions I had about the installation. Overall I would say it took me 20 minutes to install both devices in our helmets. Fits i90 HJC helmets. The intercom sound quality is good. The volume can be very high. The amount of wind noise your helmet lets through affects the sound quality. The music quality is good for speakers, it's by no means AirPods or Beats quality, but it's good for the price paid.
