Short video - Headset, in-ear and earbuds headphone left and right stereo sound channel test. Full video: https://youtu.be/Tqrj0CiZ8pQ This channel audio test is necessary when you repair your headphones to make sure the sound is correctly divided between the channels. I always use left & right sound test when install or replace old, broken 3.5mm stereo or 3.5mm 4 pole jack/plug or when repair/fix and replace broken headphone cable. I hope that this stereo channel test useful.
