BOSE Headphones, bluetooth.

I feel that I have exhausted all netly remedies to my problems.  I cannot get my Windows 7   computer to pair with my BOSE QCll wireless bluetooth headphones.  Computer lists said headphones in devices and printer but does not indicate that is paired.  These headphones are new, work well in several of my other devices. I am using a CSR 4.0 bluetooth USB adapter.
