Your experience with the MBS-200 bluetooth speaker

I'm looking to pick one of these up, but I would like to get some feedback if possible.

According to youtube vids and other reviews that i've read, they are much better than the MBS-100's which were apparantly terrible and no better than the output of your phone's speaker.

How is the 200 for volume and more specifically bass. Also, battery power. Would 'it' and the phone last a good 6 hrs. I want them for work.

At the moment i'm using a nice little USB pair called "Head Rush Mercury Wave".

Similar to the X-mini-II's. Great sound and extensive battery life, but a wireless connection would be much more convenient.
