Do you know how to quickly distinguish 3.5mm headphone mono or stereo?

Today I will show you how to do this.

1. If there are two rings, the connector is divided into three parts. It is stereo.

2. If there is only one ring, the connector is divided into two parts. It is mono.


  1 is for g rounded connection 
1 and 3 compose the left channel
