In electrical and mechanical trades and manufacturing, each half of a pair of mating connectors or fasteners is conventionally assigned the designation male or female. It is an insulating band. The band separates the parts of the plug from being shorted together. TRS still cannot carry a balanced stereo signal. However, they work the same way. Do you like this article? Did we miss anything?

By Eric D. This is the least common type of jack and plug of all. Although it can still be found in some products today. The 2. While this is by far their most common and recognized use, hence earning the name, they can be found in many other applications.

With a larger variety of uses now becoming more recognized, you might hear the newer, more accurate term is used. Here are some other places you can commonly see these jacks and sockets used. Each type has different connection capabilities and is wired slightly differently. This allows them to send and receive different types of signals. So, next, I will cover in detail all the different connection capabilities currently available. Each jack and socket could be wired differently, changing the types of signals they are capable of carrying.

They will have multiple conductors and internal wires, which can be identified using tips, rings, and sleeves. The tip, as you would expect, is the very point of the jack. For jacks with rings, they are located in the middle section, usually separated by a rubber ring.

The sleeve can be found at the very base of the jack. At the very least, a jack will contain a tip and a sleeve. Depending on how many signals are required, a ring can be added. Each ring introduces an extra wire, therefore increasing the number of signals being sent along the cable. Sockets follow the same process, however, in reverse. Any jacks or sockets with rings can be used universally; however, all the functions might not operate.

With TS connections, there are two wires found within the cable. One wire is attached to the sleeve, providing both ground and return channel for the audio. The second wire, which is attached to the tip, provides a mono audio channel.

TRS connections are much more common as they provide a stereo audio signal. This introduces an extra wire within the cable, making three in total. There are two different types of TRS wiring, with the most common being unbalanced.

The sleeve wire once again provides both ground and return channel. This time, however, the tip wire provides the left channel, and the ring wire provides the right channel. With an unbalanced connection, which is most commonly found in headphones, there is only a single signal being sent. It is then diverted to the left and right sides of your headphones or speakers. The wiring is slightly different. The sleeve is still the ground and return channel.

However, the tip is the positive signal, and the ring is the negative signal. If you plug a set of headphones or speakers into a balanced socket, the sound will be terrible. This is due to equal signals being sent to the opposite polarities of each driver. With most headphones now offering a microphone function for use with smartphones, computers, and tablets, an extra channel is required. Adding an extra ring provides an extra wire and channel.

The wiring for TRRS connections follows two different standards. Before the OMTP standard was followed, using the following connections.
