My Qilive bluetooth headphones, which worked fine in 17.04, won't pair with my PC following a clean install on 17.10. Sometimes they show up very briefly in the list of detected devices before disappearing. I've had no problem pairing a smartphone, however.
The solution offered here didn't work as I can't pair the headphones if the computer can't see them.
Output from ls /var/lib/bluetooth is 00:C2:C6:14:A4:5A

Had a similar problem, but actually the solution you identified is indeed working. In order for Ubuntu to detect your device you have to make sure that this latter is in pairing mode with your pc's bluetooth off. Once the device enters in pairing mode you activate your bluetooh and the device will appear in the list.
