My headphone connects to my laptop but doesn't output any sound. (Wireless)(Bluetooth)

I have a boat rockers 550 headphone. I have RPM fusion installed. When I connect my headphones to my laptop via bluetooth, it neither take any input audio nor recieves any output audio. I kept the codec to a2dp sbc. I tried other codecs and mSBC works but audio quality is much worse. How do I fix this?
