Domio Sport Bluetooth helmet system is claimed to provide music without internal speakers and messy wires. However, we have our concerns about this product and issue a warning to riders to be cautious. The Canadian company launched a Kickstarter crowd-funding campaign to raise the funds to start production of their Domio Pro unit that now comes with a microphone system that has no internal or boom mic. Their Facebook page says they are shipping in June 2019 and they contacted us to say they would send one for review. Social media has been rife with complaints about product not arriving and there is a complaint about the quality from a reader at the end of this article. We warn riders of “Buyer Beware” with this product, as with any product. UPDATE: The review unit has now turned up. Please click here for our review.

It’s not a Bluetooth intercom unit, so if you want to talk with another rider or your pillion, you will have to call them on your phone. You can pre-order Domio Pro now for a 35% discount on the retail price of $US199 (about $A270).
