I searched on forum but it didn't hit much result, and I thought this is perfect companionship with Z1, I decided to ask my question here.

First, do anyone own this?

Sony SBH52-screenshot2014-01-30at20327pm_zps7d5010bf.png

I recently purchased in amazon to go with my new Z1S phone, and it works well most of the part, however, It won't let me connect to 2nd device at the same time so i can just switch between my phone and PS vita.

Under the SBH52 setting, the "multipoint/singlepoint" is gray-out.
I'm hoping someone here own it and can tell me how to fix it?
