Best Bang for the Buck

I switched to Twiins from Cardo. While Twiins may not be as loud for speakers, it's more than enough.

I was able to listen to music and take calls on my cross country trip. I charged each night at camp/hotel. My bike has 2 Leo Vince pipes that are loud and I have zero complaints. Will be installing on wifes helmet soon as well I have talked many friends into switching over and they all love it.

Save 100s and you walk away happy!

I couldnt hear the speakers over the loudness of my bike:((

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!
