Serious issues with bluetooth headphones

[Ghaeng]

I have some problems with my bluetooth headphones..

1) My headphones almost never connects automatically when I power them on. I have to go to control panel, click sound and right click on the headphones and connect them manually everytime I boot my pc.

2) Connecting my headphones while Im playing a game causes windows to crash completely (windows basically freezes) and I have to log out or reboot my computer.

My PC is a Lenovo K450.
My bluetooth usb adapter is a belkin usb bluetooth 4.0 adapter.
My headphones are a pair of harman kardon soho wireless.
System specs are in my profile.

I had a similiar issue with the "telephony" setting with my bluetooth headphones. It would cause my games to crash when enabled. Go to Control Panel --- Hardware and Sound --- Devices and Printers --- Select your Bluetooth dongle / headphones, right click on it, click properties. then click services. Then DISABLE HANDSFREE TELEPHONY. This fixed my issue.
