A few weeks ago I borrowed my brother’s bluetooth speaker for my daughter’s birthday party. It was awesome except that with all that bluetooth radiation in the room it seemed to interfere with the audio quality. Since then I have played with a few of my friends devices and one is much better than the next. The big jawbone device is looking very nice to me although the mini looks much more practical. Frankly I’d like to have both. One feature that makes the mini compelling is the built-in micriphone and multi-play.
