Had the same issue. After messing around with it for about 3 days, I finally got the QC35's to connect and play music coming from the computer.
- Purchased targus bluetooth 4.0 dual mode micro usb adapter at office supply.
- Uninstalled bluetooth drivers that my computer came with.
- Download the targus drivers and software - It comes with a disc, but I don't have a disk drive on my computer so I had to go to https://www.broadcom.com/support/bluetooth and download the software/drivers for the bluetooth device.
- Once bluetooth device is setup, you should be able to connect your headphones and it will install the drivers needed automatically.
- Restart computer and turn your headphones on while booting up. - Not sure if they have to be on or not when the system is starting up because I haven't tried it any other way yet.
- Open up your devices/printers and they should show up in there. Double click the headphones icon to open your bluetooth device control and click connect. I have speech recognition disabled because I don't need it at the moment so not sure if it works or not.
- Open Audio devices and make sure there is a green check mark next to:
Headphones
Bluetooth hands free audio
Defualt Device
Should be good to go after that!
I can't skip songs from the QC35 when listening on my pc, but it's better than having no music at all to listen to while at the desk. I haven't tried to connect to my phone while being connected to my pc so you can try that at your own risk lol.
Oh btw.... I am running a Dell Latitude E5450 Windows 7 Enterprise 64-Bit
Hope this helps...
