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

785 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?

After the insulating ring you have the ring which is for the right speaker. then another insulating ring. after that you have the sleeve which is the ground
