This is actually really useful to know. I have some Bose QuietComfort 35s that I use for work calls. I'll need to replace at some point and I've read a lot of positive things about the Sony equivalents. But it's a common use case that I realise my battery is low in the middle of the day (or in the middle of a call!) and I need to plug them in. Even the Bose isn't great here because plugging it in causes a Bluetooth disconnect and reconnect which sometimes confuses Windows. So I have to power off, plug in, power on. But I can at least use it as a wired headset then.
