zoA2DP lets you pair bluetooth headphones and play music from Windows Media Player on your phone wirelessly. Advanced Audio Distribution Profile (A2DP) basically allows your phone to send
audio over
bluetooth at a normal frequency.
Just
install zoA2DP and after a restart you should be able to pair your bluetooth stereo headphones and listen away in wireless bliss.
Take note, that when you pair your headphones, be sure to check Wireless Stereo. This is the new capability that is added with A2DP.

Notice the music note icon in the titlebar indicating that A2DP is enabled. This will only come on if a wireless stereo device has been paired.
