I just read a test of all the main communicators. The new Scala won by a long shot. The Sena came 2nd last. The only one that was rated worse was the Chatterbox, which incedentally was the priciest one as well.I have a Scala G4. Using the curly cord to run IPOD music into my helmet, I got 22 hrs of music into my helmet without stopping to charge the Scala, and the red low battery warning light still wasn't on. Middle of nowhere West Virginia, I decided to charge it in a restaurant at that point anyways. Using Bluetooth for music streaming will reuce battery life to a mere 6 hrs or so. I never use the Bluetooth on mine, nor do I pair it to my phone. Mostly because I don't ride locally, and I don't use my cell when in the USA unless emergencies warrant it. I voted for the Scala, becasue the chances of your riding buddies having compatible communicators are higher if you have a Scala. The range on open freeway can be almost out of sight, and in the mountains I can get as much as 30-60 seconds ahead of fellow Scala riders and still maintain contact. Very handy for "gravel midcorner in right side of lane", or "State Trooper in restaurant parking lot" etc.
