The only other Bluetooth headphones I've had access to recently were a pair of Bose QC35 (1st generation). They showed up in the list of visible BT devices, but my laptop couldn't connect to them at all, despite numerous attempts. As a result, I bought the Sonys and got rid of the Bose.
If you take a look at bug 1724919, you'll see that other people have the same problem with other models of headphones. Attached is a copy of /var/log/syslog since last boot, with minor cleaning. Note that just after booting I wanted to use the headphones for real, so I manually ran the attached 'headphones' script to disconnect the headphones, reconnect them, and force A2DP mode. Then at 18:09:17, I deliberately recreated the bug by connecting the headphones, and unsuccessfully trying to set A2DP in the sound settings. ** Attachment added: "syslog_cleaned.txt" https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1854392/+attachment/5308567/+files/syslog_cleaned.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1854392 Title: Bluetooth headphones won't use A2DP on reconnect Status in bluez package in Ubuntu: Confirmed Bug description: *** This bug is the same as bug 1724919, but is NOT A DUPLICATE because that bug was closed because it was reported for Ubuntu 17.10, which is out of support. This bug is for newer versions, such as 19.10. PLEASE DO NOT MARK THIS BUG AS A DUPLICATE. *** On Ubuntu 19.10 on my Thinkpad T470s, my Sony WH-1000XM3 headphones pair using Bluetooth with no problems, and use A2DP by default. If I then power off the headphones and power them back on, they reconnect but use HSP/HFP and sound terrible. If I manually go into the sound settings, A2DP is offered as an option, but selecting it doesn't take effect. The headphones remain stuck in HSP/HFP mode. Unpairing the headphones and re-pairing them again selects A2DP by default, until the next time I switch the headphones off. Then they're back to stuck in HSP/HFP until I unpair them once again. I therefore need to unpair and re-pair them every time I want to use them, which is a nuisance.
