bluetooth problems after update to 7.0 - not connect correctly / no remote control via Headphones

[rosco05]

Hi, 

I have a pair of Sony MDR-XB50BS buetooth headphones that work fine with my old Z1 compact but with my X compact the play/pause/skip buttons don't work. I can receive calls with these buttons on the headphones but can't control my music.

Can anyone help me?

Many thanks
