TS, TRS and TRRS connectors - what's the difference and when to use them?
These connectors look similar, but their purpose is different. If you choose the wrong one, you may encounter audio problems, such as a broken microphone or noise. Here is a brief guide to their differences and usage:
- TS connector : For mono signal, usually used for guitars and short cables. Sensitive to noise.
- TRS connector : For stereo or balanced mono signal. Perfect for professional audio equipment .
- TRRS connector : For stereo sound and microphone signal. Used in smartphones, headsets with microphone.
Why is this important?
Properly selected connectors ensure better sound quality and reduce interference. Later in the article you will find a more detailed description of each connector and tips on how to avoid compatibility issues.
TS vs TRS vs TRRS AUDIO CABLES: What's the Difference?
TS connector: what is it and how to use it
A TS connector is a simple audio cable with a signal-carrying end and a grounding end. The two are separated by a single black ring [1] [2] .
TS cables carry a mono signal and are quite susceptible to noise, especially over long lengths. [2] [7] They are most commonly manufactured in 6.35 mm (¼ inch) and 3.5 mm (1/4 inch) sizes , but ¼ inch is the standard size for instrument cables. [3] Due to their simple design, TS connectors are inexpensive to manufacture, making them popular among musicians.
Electric guitars and basses are prime examples of where TS cables are used. These instruments transmit a mono, unbalanced signal, which is well suited to the TS cable design. [2] [6] In addition, the short distance between the instrument and the amplifier reduces the risk of noise.
When to use TS connectors
Once you understand the characteristics of TS connectors, it is important to know when they are best used. TS connectors are ideal for short cable runs , ranging from 3 to 6 meters in length. Longer cables can lead to signal degradation and increased noise levels [2] [3] . AUTOGARSAS.LT offers high-quality TS cables suitable for electric and bass guitars and mono audio equipment.
Where TS connectors are most commonly used:
- Connecting electric guitars to amplifiers
- Bass guitar cables
- Connecting effects pedals
- Connecting mono microphones
- Mono audio outputs from older equipment
However, TS cables are not recommended for stereo or balanced signals. In such cases, one audio channel may be lost or noise may increase. Also, avoid using TS cables in environments with strong electromagnetic fields [7] .
In Lithuania, using the metric measurement system, when choosing cables, it is worth paying attention to their length in meters and making sure that they are compatible with your audio equipment . In the next section, we will discuss TRS connectors, which are designed for different signal transmission.
TRS connector: what it is and how to use it
A TRS connector is the end of an audio cable that has three conductors: a tip , a ring, and a sleeve. This connector is easily recognized by the two black insulating rings that separate the three metal parts. TRS connectors usually come in two sizes: 3.5 mm (mini-jack) and 6.35 mm (¼ inch).
The TRS connector can carry either a balanced mono signal (where the tip is positive, the ring is negative, and the sleeve is ground) or an unbalanced stereo signal (where the tip is responsible for the left channel, the ring is responsible for the right channel, and the sleeve is ground). The balanced signal reduces noise levels, making this connector ideal for professional audio solutions.
By using balanced TRS cables, the signal can be transmitted over longer distances with lower levels of interference, which is essential in professional audio systems. TRS connectors are also often used in insert cables, which are designed for effects loops in mixers. In this case, a single cable splits the signal into send and return channels.
In studio headphones and audio interfaces, TRS connectors allow for clear stereo sound and balanced line-level connections. AUTOGARSAS.LT offers high-quality TRS solutions and professional consulting. Below, we will look at when and how best to use TRS connectors according to different signal types.
When to use TRS connectors
TRS connectors are indispensable in situations where high-quality stereo audio transmission is required. For example, they are perfect for connecting studio headphones to audio interfaces or mixers. Using balanced TRS cables, you can connect professional audio monitors, achieving extremely low noise levels while maintaining sound quality.
TRS connectors are also widely used at mixer insert points for effects processing. A single cable carries both send and return signals, making studio setups much easier.
However, it is important to pay attention to compatibility: if a TRS connector is inserted into a TRRS socket, stereo sound will be reproduced, but the microphone function will not work. AUTOGARSAS.LT specialists will be happy to help you select the right connectors to ensure that your equipment works smoothly.
Next, we will discuss TRRS connectors, which have an additional contact and are designed for different audio transmission needs.

TRRS connector: what is it and how to use it
A TRRS connector is the end of an audio cable that has four conductors: a tip , two rings , and a sleeve . These conductors are easily identified by their three black insulating rings. A TRRS connector allows for stereo audio and microphone signals— the tip is for the left channel, the first ring is for the right channel, the second ring is for the microphone signal, and the sleeve is for ground [1] [2] . Let’s take a look at some of the ways this connector can be useful for your audio equipment.
TRRS connectors are typically 3.5mm in size and carry an unbalanced signal. This means that longer cables can be more susceptible to noise, but for short cables, such as those used in smartphone headsets, this is not a problem [4] .
It is important to know that there are two main standards for TRRS connectors – CTIA and OMTP. Most modern devices support the CTIA standard, but compatibility issues may arise if your headphones and device use different standards [3] . If you are unsure, AUTOGARSAS.LT specialists can help you choose the right connector and check its compatibility with your equipment.
When to use TRRS connectors
TRRS connectors are ideal for use with smartphones, tablets, and laptops where both stereo sound and microphone functionality are required. [1] These connectors are widely used in headsets with integrated microphones, gaming headsets, and other communication devices, as a single connector eliminates the need for separate cables.
They are also indispensable for video conferencing, audio recording, and gaming, where two-way audio communication is required. In some audiovisual systems, TRRS connectors can be used to transmit not only audio, but also composite video signals [1] .
However, it is worth noting that if a TRRS connector is connected to a TRS jack, the microphone function may not work or audio problems may occur [6] . In such cases, a special adapter may be required that separates the audio and microphone signals.
AUTOGARSAS.LT offers high-quality TRRS solutions and professional consultations that will help you avoid compatibility issues. In the next part, we will discuss how to choose the most suitable connector for your needs.
How to choose the right connector: a step-by-step guide
When choosing the right connector, it’s important to consider the type of signal, the devices you’re using, and the environment. Start by checking the output jacks on your source and the input jacks on your destination device. For example, if your guitar has a standard jack and your amp has a matching input, you’ll likely need a TS connector. Meanwhile, professional studio equipment often requires balanced TRS connectors, which provide better sound quality, especially when using longer cables.
Cable length and environmental conditions are also important factors. For short cables, such as connecting headphones to a telephone, TRRS connectors are commonly used. However, for professional situations where it is important to reduce the effects of electromagnetic interference, balanced TRS connectors are better suited [2] .
If you encounter compatibility issues, you can use adapters such as TRRS to TRS converters [6] . The table below lists the main differences between the different connectors.
TS vs TRS vs TRRS: A Quick Comparison
| Connector type | Signal type | Typical devices | Usage environment | Compatibility notes |
|---|---|---|---|---|
| TS | Mono, unbalanced | Electric guitars, basic audio equipment | Instruments, short cables | Not suitable for stereo or microphone signals |
| TRS | Stereo (unbalanced) or mono (balanced) | Headphones, mixers, studio equipment | Professional sound , headphones | Can be used for balanced mono or stereo |
| TRRS | Stereo + microphone | Smartphones, tablets, headphones | Mobile devices, games, calls | Microphone may not work on TRS jacks |
To distinguish the connectors, you can count the black insulating rings: TS connector has one ring, TRS has two, and TRRS has three [1] [5] .
Following these guidelines can help you choose the most suitable connector. AUTOGARSAS.LT offers a wide range of TS, TRS and TRRS cables and adapters and provides expert advice to help you find the best solution for your home, car and professional audio needs.
Ensuring the best audio connection
Choosing the right type of connector is one of the most important steps in achieving high-quality audio transmission. An improper connection can cause various problems - for example, if a TRS cable is connected to a TRRS jack, the microphone may not work. And when using a TRRS cable in a TRS jack, only one headphone can work. In such cases, special adapters or hubs help, which solve compatibility problems. Professional sound systems often use these solutions to ensure smooth operation in different situations.
Given the characteristics of the connectors, the right choice is essential for both home theaters and car audio systems . For home theaters, TRS connectors are recommended, which ensure balanced sound transmission and reduce noise. For car audio systems, the choice of connector depends on the functions - if the system supports hands-free equipment, both TRS and TRRS connectors may be required. Meanwhile, for DJ equipment and studios, TRS connectors are the standard due to their ability to reduce noise and ensure a stable audio signal.
