Can I use my android phone to enable my computer to access bluetooth devices?
So, actually making your phone into a bluetooth dongle is a lil' bit nasty due to permission issues. BUT, there is another way. As you are willing to use this "measure" to stream your PC's audio to your bluetooth headset, you can download an audio streaming app from the appstore (such as SoundWire for Android), set up the connection between your PC and your smartphone, and THEN you share your phone's media through the phone's bluetooth service to the headset. Maybe there can be a loss of syncronization for games and videos, but music will be just fine! Hope it helps
