Gregory's Server@fraggle Haha I kind of do this on purpose:
My newest mouse can do USB, fast RF, and Bluetooth. Initially, when I thought I should charge it, I would unplug the 2.4 GHz receiver from the mouse cable so I could plug the mouse cable into the mouse, and it would switch automatically to USB.
However, given that radio performs identically to cabled, I found out it's much simpler to leave the receiver connected to the computer and plug a simple charging cable into the mouse.
OTOH, I'd never try that with my keyboard, which can only do USB or Bluetooth. BT has become very good, but for an input device, it's not quite as good as cabled.
For head-/earphones, the difference is night and day. My fondleslabs have headphone jacks, but if I had to use an adapter (lightning, USB-C, whatever) to get that jack, it would be even more clear: I'm using the cable for a reason; Bluetooth will never ever suffice in that situation.
