Airfun Pro 3 working on mobile not on laptop

I have a pair of Airfun Pro3's they work perfectly on my mobile phone. However on my laptop although they are paired and connected the sound doesn't work. All volumes on laptop are up to maximum. I have tried everything I can think of. Has anyone else experienced this? If not, any ideas? Also they were working perfectly on my laptop 2 days ago. I have no clue.
