What it does
- Rider-to-passenger or rider-to-rider conversation, usually over Bluetooth or a mesh network.
- Voice directions from a navigation app.
- Phone calls and, if you choose, music.
Choosing one
- Check that it is compatible with your helmet shape and that the speakers sit comfortably by your ears.
- Look for good wind noise reduction and a clear microphone.
- Consider battery life for your longest rides, and water resistance.
- If you ride in a group, check how many riders it supports and that the group members use compatible systems.
Fitting it safely
Install the unit on the helmet as the manufacturer instructs. Do not drill or glue the shell in a way the helmet maker does not allow, since it could weaken it. Keep wires clear of the visor and chin strap.
Using it without losing awareness
- Keep the volume low enough to still hear traffic, sirens and your own bike.
- Set up everything before you set off, and use voice commands or handlebar controls rather than the phone.
- Avoid long calls. Your attention belongs on the road.
- Consider leaving music off in traffic, and in places where you need to listen.
Check the rules in your country. Some places restrict headphones or phone use while riding.
