Hi Methos, I own a Droid Razr Maxx and am evaluating a Bose Soundlink and a Jawbone Big Jambox bluetooth speaker. I've been streaming music from Motorola's My Music and from TuneIn radio a lot over the last few days. I have not noticed any BT dropouts.
However, the Bose Soundlink has the same volume issue you've been experiencing. It works find with the Jambox though. This is really disappointing because I like the sound of the Bose quite a bit more, but that volume problem is a deal breaker.
