Smart Duo (Bluetooth 4.0)


We’re letting go of our previous generation devices containing Bluetooth 4.0 at a discounted price. Note that our current 5.0 devices are 15% louder and offer a 20% longer battery life. All sale items are final sale and cannot be combined with any other offers or discounts.


What’s better than one hands-free device?

Two hands-free devices—because sometimes you need a pal to come along for the ride. Meet our Smart Duo: a cost-saving solution that bundles the HF3.0 and the HF2.0 together.

Smart Duo is perfect for all motorcycle riders and their passengers. With a click of a button, the HF3.0’s Intercom pairs easily with the HF2.0, ensuring easy communication and the ability for riders and passengers to connect to the world around them. Maybe it’s a scenic first date along the ocean. Maybe it’s a Sunday drive through the hills with your spouse of twenty years. Or maybe you’re just best buds crusin’ around on your new bike. Regardless of who’s riding with you, each HF device can connect to individual phones, allowing your co-pilot to listen to their music while you take a call.

The reason for the ride doesn’t need to be the same, but the way you connect should be. With Smart Duo, you don’t need to go it alone.

I haven't received it yet I don't know. Would have been nice to have it. I called on the 24th they said it might be here by the 30th so hold your next one till I get the product I paid for on the 13th

Smart Duo

Sound could use a lot more base, to much treble and sounds like a transistor radio

Thomas Lindsay

Was easy to setup but have noticed a lot of wind noise on the intercom

Uriel Basurto
Great product

Easy to setup and install, can move from one helmet to other in minutes and good sound I do recommend it to anyone

Really like the duo connection

I like how you can seamlessly switch from intercom (passenger) and cell phone connection. It’s really nice driving with your copilot and you get a phone call. My only complaint is the audio isn’t quit loud enough. I know that depends on your helmet quality and motorcycle pipes. All in all I’m really impressed
