Can anyone recommend a bluetooth headset (i.e. speakers and mic) which does not have this issue, as mentioned in the article:

"Low quality. Related to the codec issue, many bluetooth devices will play high-quality audio when the microphone is turned off, but degrade to much lower-quality audio when it’s turned on. You can test this for yourself if you have a bluetooth headset: play music on it, then open your microphone settings to the page where it shows the mic input volume. You’ll probably hear the audio cut out for a second, then return at lower quality. (This happens even with devices you might expect to be high-end, like my Airpods Pro + 2018 Macbook Air.)"

I have need trying to find any, but have failed till now, and do not have unlimited budget to buy and try many options.
