I bought a chatterbox Xbi2 about 2 months ago.
I have been an earbud guy for a long time but got tired of having one side fall out all the time. I heard scala wasn't very good and had heard nothing but good about C-box.
It took some getting used to but it's not to bad. Not as much bass as I'm used to but I can hear my music even over my exhaust. Phone call quality isn't the best but at least now I can hear when people call me and have a short
Comvo. Battery life is like 4-5 hours. I rode to Miami and back a few weeks ago and it didn't die until I was about an hour from home.
It's taken some getting used to but it really isn't that bad. One thing I hate though is that sometimes the Bluetooth signal is interrupted and the music skips and is very broken. It only does it every once in a while but when it does it's aggravating.
