Issues with Earfun Air Bluetooth earphones

[guybu]

Since updating to Ubuntu 24.04 a few weeks ago, I've been having problems with my Earfun earphones (https://www.amazon.co.uk/EarFun-Wire.../dp/B088H7GMHZ).

They worked fine before, but now they cut in and out, and the sound distorts intermittently, which makes them impossible to use for meetings.

Please let me know what further info you'd need in order to diagnose the problem, I'll do my best to find it!

I've had a search for Bluetooth logs on the forums, and I've used the terminal to run a few commands, but I don't know what I'm looking for.

What command should I try? Should I run commands with the earphones connected?

Just let me know and I'll copy/paste outputs here.

Thank you for your reply, sorry for the delay in my own response.

Here's what happens when I run the first command in a terminal:

I don't know how much you need, there's a lot to copy and paste, so that's the last part.


Here's what I got when I ran the second command:
