Ive just had a software/firmware update for my Sony XMS4 buds so you can connect 2 devices at the same time. And it does this, with 2nd device going though your phone first and then to the buds. So even though the 2nd device thinks its connected to the buds,, its reallly not, its connected to the phone and then the phone sends the sound to the buds. The volume even automatically changes on the phone when I increase/decrease the sound on the 2nd device...... Clever hey?
