What is a TRS connection?

A TRS connection is an audio connection. This stands for: T: Tip, R: Ring, S: Sleeve. TRS is used for stereo sound. The Tip is used for the left audio channel, the ring for the right audio channel and the sleeve serves as ground. TRS connections come in two common sizes: 3.5 mm (also called mini-jack) and 6.35 mm. The 3.5 mm variant is often used for consumer electronics. Think of a directional microphone or pin microphone for a camera. 6.35 mm is more often used in the professional audio or music world. For example, for electric guitars or keyboards. You cannot record audio and listen to audio via the same cable with a TRS connection.

Which devices can use TRS?

It is difficult to indicate which products use TRS. Therefore, always check carefully what kind of connection your device has. It varies a lot between products. Many cameras use TRS, although there are also video cameras that have a TRRS connection. Older laptops and computers often also have a TRS connection. In addition, TRS is very popular in the professional audio world, for example in sound systems, mixing consoles or audio interfaces.

Why can't I connect a microphone with a TRS connector to my phone?

Modern phones are equipped with a TRRS connection, but this does not mean that you cannot connect devices with a TRS connection to your phone.

This is because the first two rings on a TRS connection are in the same place as on a TRRS connection. These ensure that you can listen to audio. With a TRRS, the ring for recording sound is at the very bottom, which means that a phone can only use a microphone with a TRRS connection.

With TRRS this is possible, for example, you can send and listen to audio via 1 cable from earphones at the same time. This is very useful for smartphones, because otherwise you would need 2 connections for this.

How do I recognize a TRS or TRRS connection?
