My soundcard (Sennheiser HDVD800) has a 6.35mm jack output that I'd like to adapt to listen on my earphones (3.5mm connector). However, I'd like to retrieve only the first channel (L or R) outputted from the soundcard in both earphones (I am not interested in the other output on this specific output).
Will it work if I use a mono jack adapter (6.35 to 3.5mm) on the stereo output? Will the dropped signal not interfere with the other channel? If no, do you have any suggestions on how to achieve this?
