## Description

One truth about working with audio is you always need the cable or adapter you *don't* have in your toolbox. That's why Adafruit love these terminal-block audio connectors so much. **No soldering required!** Use stranded or solid core wire and a small screw driver to create custom wiring jigs.

This is the **3.5mm (1/8") 4-Pole (TRRS) Audio Jack Terminal Block**. TRRS stands for Tip, Ring, Ring, Sleeve. It has four total pins - three signal and a ground as opposed to [a more common stereo jack's three](https://core-electronics.com.au/3-5mm-1-8-stereo-audio-jack-terminal-block.html). This type of connector is most often used in smartphones & cellphones to provide stereo audio and one mic channel.

Note that the green block labels it as GND-blank-Right-Left which is the most commonly used order. However, it would be more technically correct to just label it Sleeve-Ring-Ring-Tip: goes in the same order as the four contacts on the plug.

[We also have a (matching) 4-Pole Audio Plug Terminal Block.](https://core-electronics.com.au/3-5mm-1-8-4-pole-trrs-audio-plug-terminal-block.html)
