For real quality improvement which is 48kHz stereo + mic, you'll also need GMAP(Gaming Audio Profile) support both on BLE adapter and headset.
I've tried multiple combinations with my WH-1000XM6 and WF-1000XM5, but nothing works stable on Windows. Linux requires hand-patching bluez and friends which also failed for me. Android does not support GMAP and just when using LE, a lot of messengers unable to detect it properly(Google Meet works, Telegram and Viber does not).
I've finally gave up on that idea. Just thinking about fact we cannot use duplex wireless audio in 2025 pisses me off so much tbh.
Worse yet, I got a new Bose headset with USB C audio support - and the microphone doesn't work at all on either the USB or Bluetooth while USB C is playing audio!
My WH-1000XM5 set broke, and it was going to cost more to repair it than buy than simply buying a new pair. So I decided to check out the cheaper end of the market, and bought a pair of Edifier W830NB.
They are pretty decent (notable downgrade in most aspects, you do get what you pay for, but good enough for my daily needs). But I was very happy to discover that when plugged in via USB-C, the microphone works over usb with full quality, that's one thing my WH-1000XM5s couldn't do, nor the newer XM6s
