Cell Phones with audio jack plug

The audio jack plug, sometimes also called a latch, is a type of plug used for headphones. It is available in 2.5mm and 3.5mm but the 3.5mm version is by far the most popular for electronic devices such as mobile phones, tablets and laptops. In recent years, however, it has become increasingly common for manufacturers to omit the port. Due to lack of space or economic reasons.

History audio jack

The audio jack, also called headphone jack or TRS jack, is an invention that dates back to 1878. The plug has always been used to transfer audio, in the beginning mainly on switchboards. The plug consists of multiple parts so that in addition to 2 sound channels also data can be transmitted with it. The latter is often used for a microphone or a control button. The 3.5 millimeter version of the audio jackplug that we all know by now dates back to 1960. This variant is also called TRRS; Tip, Ring, Ring and Sleeve.

Disappearing headphone port

In 2016, Apple shocked friend and foe with the iPhone 7 and 7 Plus without releasing this port. Apple found the port superfluous because you could also connect headphones to the Lighting port via an adapter. Moreover, leaving it out would create space for more important components, such as a larger battery. It would also improve sound quality and make the device more waterproof. Apple got a lot of criticism on this decision, it would like to drive the sales of the wireless AirPods

Many other phone manufacturers now saw it as an advantage that their phones did have the port. Many even advertised with it. Yet in the years that followed many others also said goodbye to the beloved gate. Apparently consumers didn't think the gate was as important as they thought. Possibly helped by the enormous success of the AirPods. Samsung, Google, HTC; all got rid of them. Others like LG and Sony see it as a distinguishing feature by equipping their phones with it.
