I have a desktop PC with Windows 7 installed and I just purchased a
pair of Bose Quietcomfort 35 II Noise Canceling headphones.

The headphones do not come with a USB adapter for Bluetooth pairing,
and my desktop PC motherboard does not have Bluetooth capability.

I think that I need to purchase some sort of USB Bluetooth adapter from
a place like Best Buy etc.

Which one do you recommend?  Or maybe is there something else that I
need to purchase?

And what kind of software will I need to do the pairing?

I definitely do not want to use my Bose headphones with a 3.5 mm audio
cable plugged into the desktop PC!!
