Duo does good.

These are great little units, perfect for rides around town. Battery life is questionable. Really depends on how talkative your companion is.

Great price they work great

They work great.

One in each helmet

You have to have the right style of half helmet, but i have one in each helmet so that I'm not swapping one unit over and over. for your music pleasure, it's like listening to your stereo's tweeter, but two way coms volume is great. Loud enough for straight pipes, and controllable for the quiet bikes!

Sebastian Medina
Great price

As a musician, I was concerned about the sound quality, and it sounds about the same as a $10 head set from Walmart. But!!!!! It does the job way better. I get hands free feedback, I can take calls and activate Siri. I can hear it over my bike which reaches 100dB.
And I also got a headset for my wife. This is a deal that really cannot be passed up.
I wish I could change out the speakers, but they’re still great.

Easy install!

Love the device as I placed both units in my and my wife’s helmet easily. I am running into trouble with blue tooth interface because I have an Apple Watch, hearing aids, and my Twins headset competing. I am working on what to do.
