Headphone plug pinout

Despite the fact that manufacturers try to produce the highest quality products, sometimes you can notice the occurrence of various defects. Most often, due to constant bending, the user experiences sound distortion. Thus, it is recommended to resolder the connector. How to do this will be discussed in this article. In addition, we will look at the question of how desoldering is done, depending on the equipment model.

Plug types and applications

There are several classifications and they are all distinguished according to different criteria. As for the surface diameter, the following types can be distinguished:

• Mini-Jack has a parameter of 3.5 millimeters. Often they are used directly to connect a personal computer or TV.
• Micro - Jack has 2.5 mm. With its help you can connect both a cell phone and a player - that is, small devices.
• Big Jack with a value of 6.35 is considered most suitable for professional equipment. These can be various amplifiers, electric musical instruments, and even ordinary microphones.

If we talk about the number of outputs, then it is worth mentioning the products presented below:

• TS assumes the transmission of a single-ended type signal.
• TS S can already transmit symmetrical signals.
• TRRS present both video and audio information at once.They are most often used in modern inventions.
• TRRRS is not as widespread as its previous representatives. It can be used to make two microphones from Sony and Xperia work.

IMPORTANT. Don't forget about the typology of nests. There are ordinary and devices with switches.

Pinout of headphone plug with microphone

It is important not to confuse a regular design with a headset. The second of these options differs from the first in the presence of a headset. Thus, the scheme will be different accordingly. The difference lies solely in the location of certain contacts. So it will be enough to just swap the two parts with each other. There are two standards:

1. TRRS CTIA is a popular category that is used in most all smartphones. If we consider the plug from top to bottom, the contacts will go in the following sequence: left channel, right, common and microphone.
2. The next representative - TRRS OMPT - is considered not as new as the previous one, but is also subject to operation. Often used in Nokia phone models. The combination is almost the same, however, it is worth swapping the last two aspects: instead of a microphone there is a common channel.

Pinout diagrams by manufacturer

First, you should understand what shades certain wires have, so as not to get confused in the future. Of course, this depends on the device model, however, the most popular cases have been identified. So, the left channel is often represented in white, green or blue. The right one is all red. If a light color was previously used, then the overall product is labeled copper.

REFERENCE. But some developers differ from others not only in color coding, but also in providing the order of the signal type.Therefore, let’s look at the most common implementation options.

Apple audio pinout

So, for such constructions the following sequence is suitable:

1. Left.
2. Right.
3. Earth.
4. Audio.

However, it is important to understand that it is not intended for all Apple representatives. Only for devices such as iPod Nano, handsfree.

Lenovo audio pinouts

For the named manufacturer, a basically similar procedure is inherent:

1. Left.
2. Right.
3. General.
4. Microphone.

Suitable for Notebook audio versions: Thinkpad Edge.

Samsung headphone jack pinouts

As for this model, this is:

1. Left channel for audio playback.
2. The right one has the same functionality.
3. General.
4. Video signal.

This includes a sufficient number of cell phone versions.

ATTENTION! Some designs may vary: mass contact varies with other locations.

Therefore, having special knowledge, it is quite possible to independently deal with this or that problem by unsoldering the connector. Thus, without turning to specialists.
