There are all kinds of motorcycle helmet intercoms.
Once you've tried it you'll never want to plug in another wire
I have the cardo scala on the cycle helmets as well as the headsets for the rzr
Sena is also popular.
even used some inexpensive ones off ebay that worked good
Are there any wireless solutions (like Sena) that would allow us to listen to the same music (from Ride Command) across 4 sets? Looks like Sena only shares music between two devices. Not sure about the others?
I have a 2019 7 button ride command if it matters.
Bluetooth headsets (I use sena) are great in the car, but as soon as you want to connect to someone in another car they are limited to line of sight. Go around a corner or over a dune and they drop. I'm going to try a radio to radio interface for the headsets, but this is a band-aid. In hindsight I'd go with a wired radio set up.
