Bug description:
Bluetooth HSP/HFP audio quality is poor on Ubuntu comparative to all
other major platforms (Windows, MacOS, ChromeOS, Android, iOS).
Modern Bluetooth headsets (such as the Bose QC series headphones, many
others) are capable of using HFP 1.6 with mSBC 16kHz audio encoding.
As it currently stands, Ubuntu defaults to only supporting HSP
headsets using 8kHz CVSD, and is incapable of supporting HFP 1.6 at
this time.
The ChromiumOS team recently tackled this issue -
https://bugs.chromium.org/p/chromium/issues/detail?id=843048
Their efforts may assist in bringing this to Ubuntu, however it
appears that there are quite a lot of differences considering they
have developed their own audio server solution etc.
The Bluetooth Telephony Working Group published the HFP 1.6 spec in
May 2011 -

Patches have been proposed in the past for this issue to the kernel
and PulseAudio:
PulseAudio: https://patchwork.freedesktop.org/patch/245272/
Kernel: https://www.spinics.net/lists/linux-bluetooth/msg76982.html
It appears that the Chromium OS team applied the same kernel patch:
