Those rings on your earphone plug, what do they mean?
Ever wondered why there are rings on your earphone plug? Well, here’s what they do:
The number of rings on an earphone plug, also known as a headphone jack, indicates the type of audio signal and functionality it supports. We have earphones with single, two, and three rings.
Single ring:
An earphone with one ring means that there are two sections, so the plug is mono audio.
In simpler terms, it means your earphones play exactly the same sound.
In essence, when you see an earphone plug with only one ring, it’s telling you that it’s a mono audio connection, meaning both the left and right earbuds will play the same audio, creating a single, unified sound experience.
2 rings:
An earphone with two rings means that there are three sections, so the plug is stereo audio.
In simpler terms, it means the earphone has dual audio channels, one for the left earbud and the other for the right earbud.
So, when you plug in earphones with two rings, you can expect to hear separate left and right audio channels, creating a stereo audio experience. This is the most common type of earphone plug for listening to music and other audio content in stereo.
3 rings:
An earphone with three rings means that there are four sections, so the plug is stereo audio plus microphone/volume control or both.
In simpler terms, it means the earphone has the same functionalities as the 2-ring earphone, but with a plus, a microphone/volume control, or both.
Earphones with three rings are versatile and commonly found on headsets designed for smartphones and other mobile devices. They support stereo audio playback, microphone input for making calls or recording audio, and sometimes additional functions like volume control or playback controls.
