1) Bluetooth -- I wanted a unit I could interface with my phone
2) Bike to Bike Intercom -- I wanted at least a few hundred feet for chatting while I ride, preferably full-duplex
3) Not too expensive -- I was buying a pair (the second as a gift for a friend) so the cheaper the better
After reading a few reviews, I decided on the Interphone, it met my criteria (Bluetooth, 500ft range for b2b, about $115.00 each on Amazon)
The Interphone mounts on the side of the helmet, either via a clamp-on bracket, or a permanent adhesive plate. Using either method, the actual device clips on and off of the mount with a simple press of a button.
I held a couple of bluetooth conversations and a couple of hours of chatting with my buddy. My wife (on the other end of the phone conversation) said it sounded like I was in the car with the window down, but that she could understand me and I could hear her (although I did end up adjusting the volume a bit). I have a modular helmet, and was traveling 45-55 mph during our conversation, my buddy has a similar helmet. We tested the intercom on some twisty roads and on the interstate, up to about 70 mph and a range of about 250' without any problems. Using the intercom, there would sometimes be some wind noise. The noise would happen not while we were talking, but during quiet points in the conversation.
Pros/Cons:
Pros -- Good noise rejection, easy to attach, good volume, good value.
Cons -- Initial pairing for Bike to Bike intercom is kind of like voodoo, but only needs to be done once, no 3-way conversations via intercom (some more expensive units allow 3 riders to talk at the same time), only one speaker (not stereo)
For my purposes, I couldn't have been more pleased with these units.
