Diamond as a bluetooth stereo headset

[Fortinbras]

Is there a way to use Diamond as a bluetooth stereo headset? When I watch movies using a projector I’d like to transfer the audio stream from my laptop via bluetooth to Diamond and listen to it using its headset. But I can’t make it work. It works perfectly in the opposite direction so I can transfer music stream from Diamond to the laptop and able to hear it through its speakers. So both devices support A2DP profile.
Is there any solution?
