I'm finally catching up w/ the 21st century and bought my first pair of truly wireless earbuds: the Sony WF-1000XM3.

My issue is that audio quality degrades significantly when I connect them to my computer and enable the microphone. To do this, I have to switch from High Fidelity Playback (A2DP Sink) to Headset Unit (HSP/HFP), which forces the output to go from Stereo to Mono.

For ~$200+, I was hoping to have better audio quality than my cheap wired earbuds+mic. I already bought 2 other earbuds at different price points and noticed similar or worse issues. Tried with Airpods Pro as well, but since I'm not on a Mac, I could never get the mic working.

In short, I'm wondering if things change significantly with something like the Sennheiser Momentum 2 (or higher price point), or if I should consider non-truly wireless earphones, if I want quality audio and mic?

Each A2DP "service" is Mono-Directional.

A typical device using the A2DP profile for music will not support more than one service (i.e. audio stream), but it's possible. This would need a more complicated chipset so it may not be suitable for the size constraints of "truly wireless" earbuds.

Unfortunately I can't recommend any headphones that do this because I haven't found a pair myself. It is often cheaper/simpler for the headset to switch to HSP for bi-directional audio.

    Thanks, Romen. I think I'll have to go the gaming headset route, which use USB+wireless adapter to support high quality audio and mic simultaneously. – Khashir Sep 17 at 20:25

The solution seems to be to buy earbuds that support a USB Bluetooth adapter, like the ones a wireless gaming headset would use (search for "Lag-Free Wireless Audio" to read about the included adapter).

According to this reddit thread (2020-07), the Jabra Elite 75t can be hooked up to the Jabra Link 370, which increase range and:

"Sound quality features such as HD voice, HiFi Audio and A2DP for crystal-clear sound for calls and music."

However, I haven't tried this myself, and Jabra Link devices are not officially supported by Jabra to work with earbuds (only headsets and speakers), so YMMV.
