[Bug 1654782] [NEW] Can not pair with bluetooth headphones

Public bug reported:

I can not pair computer and Bluetooth headset (sennheiser momentum 2.0 wireless aebt).
(If it matters, I *CAN* pair and use it on another laptop with Linux and with my android smartphone. So headset itself is working well.)

Here is how I try to pair:
$ bluetoothctl
[NEW] Controller 54:27:1E:33:4B:85 impedance [default]
[bluetooth]# power on
Changing power on succeeded
[bluetooth]# agent on
Agent registered
[bluetooth]# default-agent
Default agent request successful
[bluetooth]# scan on
Discovery started
[CHG] Controller 54:27:1E:33:4B:85 Discovering: yes
[bluetooth]# scan on

I tried to put my headset in pairing mode just before and after issuing
"scan on" command. It ends up with nothing - I waited for 3-5 minutes.
For example, my smartphone pairs with the headset in 5-15 seconds, my
laptop pairs with the headset in about 30 seconds.
