The circles (or rings) on an earphone plug are made of non-conductive material (usually plastic) and serve a crucial purpose: they separate the different electrical contacts on the plug. Each of these metal sections (separated by the rings) carries a different part of the audio signal or other functions.
See lessHere’s a breakdown of what the number of rings typically indicates:
* One Ring (TRS – Tip, Ring, Sleeve): This configuration has three sections.
* Tip: Carries the left audio channel.
* Ring: Carries the right audio channel.
* Sleeve: Acts as a common ground for both channels.
* This is the most common type for standard stereo headphones without a microphone.
* Two Rings (TRRS – Tip, Ring, Ring, Sleeve): This configuration has four sections.
* Tip: Carries the left audio channel.
* First Ring: Carries the right audio channel.
* Second Ring: Typically carries the microphone input, or sometimes a remote control signal (for volume, play/pause, etc.).
* Sleeve: Acts as a common ground.
* This is commonly found on headsets designed for smartphones, tablets, and other devices that support both stereo audio and a microphone.
* No Rings (TS – Tip, Sleeve): This configuration has only two sections.
* Tip: Carries a mono audio signal.
* Sleeve: Acts as a common ground.
* This is used for mono audio signals, such as in electric guitars or some older audio equipment.
In essence, the rings allow the single plug to carry multiple distinct electrical signals, enabling features like stereo sound and integrated microphones.
