The motorcycle blog mymotorcycletravels.com (great name by the way) recently reviewed the iMC Camos BTS 300 Bluetooth Helmet Headset and intercom. It is probably the most well written review in terms of descriptive writing. Whereas the webBikeWorld review focused more on the application and capabilities. Also check out the link to the blog below as the author provides other great posts about riding in the great state of Ohio. Quotes are below.

The speakers need to be right over your ear canals, which I took great care in doing when we installed the units. I cannot listen to my music with the volume all of the way up (unless using Pandora, which seems to provide a very low audio level for some reason). When I receive a phone call, my music automatically pauses, and i take the phone call, then my music resumes when I hang up the call.

I placed the windshield all of the way down on the BMW R1200 RT and she could hear me just fine at 65 MPH. I am not a scofflaw that would go speeding down the freeway, but I am an amateur scientist, so in the name of science, I took the liberty of testing my Camos BTS-300 intercom on a phone call at 80 MPH and still was asked by a friend “Are you really on the motorcycle?” I have no problems hearing the people that call me. The sound is probably as good as my cell phone can deliver.
