I have a pair of Bluetooth headphones (Lindy BNX-60s, fact fans!) which I want to use with my (Windows 10) PC.
I can connect it all up to Bluetooth fine, and the PC detects both the headphones and the headset, setting them up as output and input devices accordingly.
However, if I have my current input device set to the microphone on the headphones, then I get no audio at all through the headphones themselves - i.e. people can hear me talk (just) but I can't hear anything back.
If I set the input device to be my webcam's microphone, I can hear audio again.
Is this likely to be a weird incompatibility with my headphones, or is there a setting I can change in Windows that will fix this?
