Sony a6300 hack – How to connect headphones
The basic idea is to get a sound cable that splits the mic input to the Sony a6300 audio.
Connect one side (the output) of the sound splitter to the Sony a6300 and the other side of the splitter (input) to the headphone and the microphone.
(!) You have to make sure that your microphone has its own power source otherwise, this hack will not work.
