chillgreg. yup i used the headphones with my iphone and droid phone all the time to listen to music.

Are the Sony's disconnected from all other bt devices before you connect with your pc?
Have you upgraded to the latest bt drivers both through Windows Update and the Asus website?
Do the Sony's have any additional configuration options?
Also suggest checking the Sony forums.
