HJC 50B Smart Intercom

This system is the perfect fit for a compatible HJC helmet. Fitting is straightforward, if a little bit fiddly; take your time and read the instructions and it should be easy enough. Being integrated to the helmet cuts down on extra drag that an external intercom might add, but I doubt it would be that much anyway.

Sound quality is excellent and microphone is clear. Google/Siri integration is a great feature; helps reduce the amount of times you need look at your phone and/or touch the buttons. Not tested mesh yet, but this system has a lot of features to make group riding easier. Highly recommended if you have a HJC helmet and your group use Sena Intercom.

Obviously get this over the 21b if you want mesh, but the real main reason for me was siri integration, really nice being able to issue voice commands to your phone, means a lot of the time I don't even have the phone on the mount so it doesn't distract me.

It takes a minute to get your head around all the combinations of button presses for different commands, but once you do, it's a great bit of kit. Can't fault it.

Paring order can be a bit of a faff, but again, once you get your head around the logic, it's ok, app helps a lot rather that just trying to do it through the buttons on the helmet.
