BT audio quality HSP/HFP vs A2DP

I have a Jabra Elite 75t headset connected to a laptop and desktop with arch. A2DP audio quality is good, HSP/HFP works, but awful quality. I need some bcm firmware for the dongle on my desktop, but all is set up. Both connect fine/automatically and I can switch between the 2 profiles. The HSP/HFP is just so bad, everybody on a call with me points it out. And I can hear the difference as well.

Is this normal, anything to fix this? It's really like a 1990s cell phone. Headset works just fine on Android and ChromeOS.

This is indeed normal, that's the standard HSP protocol for you. Anything that works "better" is usually implemented with proprietary codecs that don't have free implementations readily available, see the following prevoius discussion for some background information: https://bbs.archlinux.org/viewtopic.php?id=255178

Thanks a lot for your pointer! I swear, I searched, before posting :-)

Not high hopes, but one more thing to play around with.

If you're looking to play around with it satchmosgroove, you're not alone -- there's a lot of people interested in this topic lately (due to the global issues), myself included.
Here's a great jump-off point: https://gitlab.freedesktop.org/pulseaud … issues/776

At the bottom there's another jump post linking together disparate forums, as well.

Re: BT audio quality HSP/HFP vs A2DP

so, update: I installed libpulse-hsphfpd. HSP/HFP profile still has poor quality to listen to, but feedback from my colleague was better. Not as good as other mics, but good enough to have a conversation.

This is not really based on the links above, but was more the result of some trial and error. I am a little hesitant to get too distracted and diving deeper into this topic for now.
