Review on 🎧 TCOM VB Helmet Communication Systems 2Riders Snowmobile Bluetooth Intercom – Waterproof Motorcycle Headset for 3 Riders – 800M Range (2Pack) by Justin Ott

If you have an older car with mechanical ignition points, this [or any other] Bluetooth intercom may not work. After installing both sets in our helmets in the test, the intercom worked even without the motorcycle running. The sound has some echo, but can be understood. After starting the motorcycle engine, the intercom stopped working. The Bluetooth interference warning should be taken seriously.
