– How does a single 3.5 mm jack provide stereo sound?

782 views

So on my way back home I was listening to music on my bike and I got fascinated by a sound panning from left to right in my earphones. (I was listening Ready or Not by the Fugees). How does a single contact like a 3.5 mm jack provide a stereo sounding effect? How is it able to split the sound between both earphones?

You will notice black bands on the jack. Stereo will have 2 bands, making 3 connections; L, R, and common. Some new headphones with buttons will have extra bands.
