Razor Kitty Kraken BT not syncing as audio to computer

HI, i bought a Razor Kitty Kraken BT and a Targus bluetooth 4.0 micro usb adapter together. The headset connects to the computer with bluetooth, but it does not reigster it as audio. If i went to audio settings in my computer, the headset is not an option.
Some specs on the Bluetooth adapter,
Class 2 adapter
supports BLE and v1.1/1.2/2.0/2.1+edr compliant devices
Distance 10 m
I am not sure if it is the bluetooth adapter nor a headset issue
