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
