Would highly recommend, long battery life, excellent volume level, waterproof, perfect for riders looking for good Bluetooths.

Sound is better than expected. Instructions on use not so good. Plenty of youtube vids though.

Great connection between the 2 units. No drop out. Speakers in them are as expected. Remind me of old Walkman headphones and sound quality. But wasn't expecting awesome speaker quality. The phone and music features are awesome. Music while in the mesh communication and phone is seamless. Siri even works.

These were pretty easy to add to our modular helmets. My review is based only on utilizing these as an intercom between my husband and myself on 2 bikes. We haven't really used them for anything else. The sound quality is good and the noise cancelation is surprisingly good until you hit the higher speeds (like 60 mph +). Then it is like the noise cancelation is trying too hard and distorts the voices. Range is pretty good, although especially when coupled with the higher speeds it becomes almost impossible to hear the other speaker with any clarity. We've been able to communicate when we were separated by signal lights in town to a distance of several blocks. So that was surprisingly good. We dont have experience with any other system so can't compare but for the price, we are very happy with these! Great value.

I've been using this headset for a few months now, and I think it was worth making a review about it because it makes my riding experience so much better than before.
To start, just for safety improvements this headset is a MUST, now when I or my friends see any imminent danger, we can help each other out.
This headset looks and feels expensive, rubberized finish and rubber caps to prevent water from getting inside in case you get some rain.
Going for a long trip and want to say something? Now you can do it any anytime, and if you want you can also mute the headset and switch to music on the fly, simply by pressing the button on the top.
Battery really lasts me for weeks, average for me is 2 weeks before needs to recharge again, of course, it depends on how long you ride for, but battery shouldn't be an issue.
I hear my friends talking loud and clear, microphone will block some wind but this will also depend on how much air gets on your helmet, with my visor open, I found that up to 50mph I can listen and talk to someone else with no problem, more than 50 starts getting harder, but like I said, depends on which helmet you are using.
The transmission range on this thing is amazing, it gets to the point where I can't even see my partner anymore and I can still hear him, no interference whatsoever!
Like other reviews mention, the volume wheel is awesome, very easy to increase or decrease volume without having to look for specific buttons and while having your hands off the grip.
I don't listen much to FM radio, but it works just fine, music sounds amazing, sounds very clear and loud.
You must install the speakers right in front of your years, the pre-cuts on the helmets are usually miss places behind or on top of your ears, so it won't sound good if you don't install the speakers correctly.
When I receive calls on this thing, it will let you set up picks up the call automatically or or manually by touching the button in the middle of the volume wheel, if you paired with your friends headset, when you pick up the call it will mute your friend, so he won't be able to listen to you or conversation, but as soon as you hang up it will reconnect to your friend automatically.
So would highly suggest you to buy this headset, just for the safety it provides alone is already a must. You will not regret, money well spent.
