When I activate bluetooth on my notebook I can see and pair with every bluetooth device near me but there is no A2DP or HFP/HSP headphones in there. Typing service bluetooth status in terminal gives me back

Full restart of bluetooth service and typing service bluetooth status again just removed last line from the feedback. I'm new to Linux systems so I can't get what to do next, can you lead me?

killing org.bluez process through sudo kill <org.bluez PID>,

then I wrote

rfkill block bluetooth
sudo service bluetooth stop
sudo rfkill unblock bluetooth

Bluetooth have been swithed off and then on after typing these commands, and my headphones appeared in devices list. Thanks to that answer
