Connect wireless headphones to a cell phone, which in turn is connected to the PC because my laptop has no Bluetooth.
I'm not aware of any such possibility.
However, you can get a Bluetooth USB stick, the costs do not exceed 15 euro.
Do not think, since your cell phone does not get the audio from the pc
You can use the cell phone with all functions, make calls, use it on the PC. The main thing is that the cell phone is connected to the PC with a USB C cable
Haha learned something again, top👌
