Any idea why some headphones have 2 and other 3 stripes on their connectors?

Do you want to know its usefulness? Here we are going to explain all the details.

1. If you have three lines

If the connector of your headphones has three stripes, that means they are stereo headphones with a microphone. The lines divide the connector into four electrical plates: Right Out, Left Out, Microphone In, and Ground.

3. If you have a streak

They are not stereo headphones, but mono. The line divides the connector into two electrical plates: audio and ground.
