Headphone pinout

Despite the fact that manufacturers are trying to produce the highest quality products, sometimes you can notice the occurrence of various defects. Most often, due to constant bends, the user is faced with distortion of sound. Thus, it is recommended to solder the connector. And how to do this will be described in this article. In addition, we will analyze the question of how to solder, depending on the model of equipment.

Types of plugs and scope

There are several classifications and all of them are distinguished by different criteria. As for the surface diameter, the following types can be distinguished:

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

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

• TS assumes the transmission of a single-ended signal.
• TS S may already transmit balanced signals.
• TRRS immediately presents both video and audio information. They are used most often in modern inventions.
• TRRRS is not as common as previous representatives. It can be used to implement the performance of two microphones manufacturers Sony and Xperia.

IMPORTANT. Do not forget about the typology of nests. There are ordinary and devices with switches.

Headphone pinout with microphone

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

1. TRRS CTIA is a popular category that is used in most smartphones. If we look at the plug from top to bottom, then the contacts will go in the following sequence: left channel, right, common and microphone.
2. The next representative - TRRS OMPT - is not considered as new as the previous one, but is also put into 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 manufacturers

To begin with, you should understand what shades these or those wires have in order not to get confused later on. Of course, this depends on the model of the device, however, the most popular cases have been identified. So, the left channel is often presented in white, green or blue. Right just red. If the light color was previously used, then the general product is marked copper.

REFERENCE. But some developers differ from others not only in color coding, but also in providing order of signal type. Therefore, we will analyze the most common options for execution.

Apple Audio Pinout

So, for such constructions, the following sequence is suitable:

1. Left.
2. Right.
3. Land.
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 similar procedure is inherent in principle:

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

Intended for Notebook audio versions of the notebook: Thinkpad Edge.

Samsung headphone jack pinouts

As for this model, it is:

1. Left channel for audio playback.
2. Right with the same functionality.
3. Common.
4. Video signal.

This includes a sufficient number of cell phone versions.

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

Therefore, having special knowledge, it is quite possible to independently deal with a particular problem by soldering the connector. Thus, not referring to specialists.
