a typical connection used to plug in headphones, such as those used by computers, music players, and the majority of other electronics having audio outputs.
Depending on how many distinct connection rings are present on the jack, it can accommodate either stereo or microphone.
Some phones only have a 2.5 mm jack, which is a more limited use of the same idea.
Mobile phone headphones typically come with a microphone located along the cord and a remote button that lets you answer and end conversations without using the phone.
Some manufacturers choose to place this remote control’s 3.5mm audio jack on it rather than the phone itself. This is because 3.5mm connectors occupy a significant amount of internal space. Additionally, the user retains the ability to utilise the remote control and microphone while utilising headphones from third parties.
