2.5mm (3/32") 4-Pole (TRRS) Audio Plug Terminal Block

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

This is the 2.5mm (3/32") 4-Pole (TRRS) Audio Plug 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. This type of connector is most often used in smartphones & cellphones to provide stereo audio and one mic channel. Note it's smaller than your classic 3.5mm (1/8"), this is when you think "wow that looks like a 1/8" jack, but it's a bit smaller!"

Note that the green block labels it as GND-V-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.
