I love motorcycle comms systems. I’ve had a Cardo PackTalk Edge for a while now, and a PackTalk Black before that — for as long as I’ve seriously ridden bikes, I’ve had a comm unit.
Universal intercoms can be fitted to almost any motorcycle helmet you choose ... won’t want to go for a Shoei helmet with integrated comms, for example, because their units are made by Sena.
Motorcycle makers have only slowly introduced ... The system also allows for audio alerts if riders are using in-helmet comms systems (below), which are becoming more popular.
