My Sony MDR-XB80BS bluetooth headphones get paired/detected but only work under a 'Headset Head Unit (HSP/HFP)' profile. Which means I only get a 'mono' audio mode, unlike nice stereo audio quality I used to get until (about) a month ago or so, when I could select 'AD2P' and audio quality was great.
Already asked about it on the forums:
@sunnyflunk was really helpful and helped me cover the basics, but sadly issue is still there.
Any info about my system that I can provide to you that could help please let me know.
In case it's useful, this is my inxi -F output:

Wasn't aware of the lsusb command used by @swoop. In case it's useful, here's also my output:
lsusb | grep Bluetooth Bus 001 Device 009: ID 413c:8160 Dell Computer Corp. Wireless 365 Bluetooth Bus 001 Device 003: ID 0a5c:4500 Broadcom Corp. BCM2046B1 USB 2.0 Hub (part of BCM2046 Bluetooth)
Hope it helps.
