Hello Adithyan - and welcome to the Forum.

It would be helpful if you could tell us details about: your computer, operating system (e.g. Kali version) and headset, as suggested here: http://linuxforums.org.uk/index.php?board=209.0

Try this:

apt install libspa-0.2-bluetooth && apt purge pulseaudio-module-bluetooth

Then reboot and try Bluetooth again.
