Complete guidance on a best jack to jack cable

Learning how headphone jacks and plugs work electrically will help tremendously in our comprehension of signal flow and device compatibility while improving our troubleshooting skills.

This is easy to plug the headphones into the appropriate jacks/ ports & have them perform until this is not. They are learning how these headphone jacks establish the electrical connection that allows the audio signals to flow. Although the specific purpose is similar, specific wiring, size, the inclusion of the microphone, connection quality & compatibility differ from the best jack to jack cable & plug to plug & the plug to jack.

In this blog, you can look at the inner workings of these multiple sizes, qualities & wirings of the headphone jacks to better understand how they perform in general and in tandem with the headphone plugs.

Difference between headphone jack & headphone plug

While most people discuss the headphone jacks, they mean both the male connectors & the female connectors at the end of a headphone cable.

But, technically speaking, a headphone jack is a female port, & a headphone plug is a male connector. It is the case with any kind of phone-style connector.

  • These are the headphone plugs.
  • It is the headphone jack

How do these headphone jacks & plugs connect?

Let’s start by stating that not every headphone jacks & plugs are also compatible.

For the headphone jack & plug to connect appropriately & have the optimal sign flow, they have to match in the following methods:

  • Be the similar size
  • Have the same wiring schematic

Necessarily, headphone plugs & jacks are single connectors with various conductors within their design. For the headphone plug to perform with the headphone jack, conductors have to be properly aligned in a correct format for transferring the appropriate audio signs.

This is essential to note that the headphones are also transducers & are inherently analog tools. The analog audio signs are simply AC voltages. These signs are also carried via electrically conductive wires.

The actual idea is to make contact between these jack & plug conductors to permit these analog audio signals to flow the actual signs from a source through this cable & to an appropriate headphone driver according to an airing scheme.

Plug sizes or headphone jack

Let’s start by discussing the multiple headphone jacks & plug sizes. Those are:

  • 2.5 mm
  • 3.5 mm

2.5mm (3\32 in)

This 2.5 mm headphone plug or jack is not very common but is also worth mentioning here for the thoroughness. This headphone jack or plug still gets utilized daily in 2 method radios & some video cameras. 2.5 mm headphone connections are typically unbalanced mono TS or unbalanced stereo TRS connectors.

3.5mm (1/8 in)

The 3.5mm best jack to jack cable is the most common for wired headphones.

This is the specific jack discovered on the older smartphones, laptops & tablets, & some audio mixing consoles & the field recorders.

3.5mm headphone connections are sometimes either unbalanced stereo TRS \ or unbalanced stereo plus a microphone TRRS.


This 4.4mm is also a relatively new headphone jack or plug.


Wires within the headphone cable are internally matched to an individual conductor of the cable plug. The audio source jack also has individual conductors that are wired to carry the particular signs.
