Shark Sena Bluetooth Duo BTD

If you are fitting comms to two compatible Shark helmets, this is the twin version of the Sena-developed Bluetooth system. It gives a rider and pillion, or two riding friends, a matching pair of units.

 

You get 40mm speakers, music sharing and Bluetooth conversations for up to four users. Settings can be adjusted through the Shark app. For many people, that will cover the conversation they want to have on the bike.

 

If joining a Mesh group is part of the plan, look instead at the Shark Mesh duo. Check that both helmets appear on the compatibility list before ordering.
