Here is my solution, first you need to open the “control” plastic (the dial-up button,etc). But, when plug it all the way in, you can’t get the mic works, and the sound is horrible. Okay, so when I plug the headphone half-way on my laptop, i can hear the normal sounds, and the mic is work as well.

To make sure that you have Nokia headphone, just plug your headphone to an android device or Nokia device and make sure its work. This method is only tested on (let say) Nokia headphone. First i want to say that TRRS pins are not always the same, i mean, the pins you mentioned above is an iPhone pins (Left, Right, Ground, Mic), and Nokia (and most headphone out there) pins are Left, Right, Mic, Ground.

Here is how to convert TRRS to TRS without anything. Once you’ve done that, the wires can be soldered directly to the inputs on your PCB, or connected to jumper wire pins so they can be inserted into a breadboard.

Before soldering or connecting them to anything conductive, run a flame over the wires quickly to burn off the insulation, then wipe clean. There’s a very thin coating of insulating material on each wire, which is how they can be bundled together without any plastic insulation. If you only need a mono audio input with the TRRS connector, you can combine the combine the red and green wires to make a single mono audio wire, then combine the ground wires to make a single ground wire. If you can get to the pins inside the plug’s housing, the pins of the TRRS plug connect like this: The TRRS plug connects to the wires like this: You’ll also find a plastic cord that’s used to strengthen the headphone cable:

Red and green sheath with a copper wire inside: Inner copper wire is the microphone signal, outer sheath is the microphone ground.

Green and copper twisted wire: ground for the left audio channel.

Solid green wire: left audio channel signal.

Red and copper twisted wire: ground for the right audio channel.

Solid red wire: right audio channel signal.

After you cut open the plastic insulating sheath you’ll find 5 separate wires: The TRRS audio plug is found on iPhone headphones and other headphones that have a microphone. Once you’ve identified the wires, simply solder them to the correct input channels in your circuit, or attach pin connectors so they can be used in a breadboard. If you only need a mono input, the left and right audio channel wires can be connected together. The wires are connected to the pins of the plug like this (image courtesy of Rob Robinette): The wires are connected to the TRS plug like this:ĭepending on the type of plug, you may have access to the pins inside the connector’s housing. Check the image below to see which wires are audio signal wires and which are ground wires in the most common TRS wiring schemes (image courtesy of DIY Perks on YouTube). Usually red wires are the right audio channel and blue wires are the left audio channel.

Separate insulated wires for the ground, right audio, and left audio inside a single cable.

Two separate insulated wires, each with its own signal wire and a ground wire inside.

Copper wire ground sheath wrapped around two insulated audio signal wires.

After you cut into the cable, you’ll probably find one of three common ways these can be wired: TRS audio plugs are found on standard stereo headphones that don’t have a microphone. The T stands for “tip” the R stands for “ring” and the S stands for “sleeve”: In this tutorial, I’ll show you how to wire the two most common types of audio jacks – TRS and TRRS.
