Now, Let’s Start with a 3.5mm Jack

3.5mm Headphone Jack:

3.5 mm jack

The 3.5mm headphone jack is by far the most common type of headphone jack. It can be found on almost all types of headphones, from cheap earbuds to high-end over-ear headphones. The 3.5mm jack is also the standard audio jack for all portable music players, smartphones, laptops, and computers.

The 3.5mm jack is also known as the “mini” jack. This is because it’s smaller than 6.25mm headphone jacks. It was first introduced in the 1950s and has been the standard ever since. It’s popular because it’s small and easy to use. Plus, it doesn’t require a lot of power to operate, so it’s perfect for portable devices.

One thing to keep in mind is that not all 3.5mm jacks are created equal. There are two different types of 3.5mm jacks:

  • TRRS (Tip, Ring, Ring, Sleeve)
  • TRS (Tip, Ring, Sleeve)

TRRS and TRS Configuration

The difference between these two types of 3.5mm jacks is the number of metal contacts.

TRRS jacks have four contacts: two for the left channel, and two for the right channel.

TRS jacks have three contacts: one for the left channel, one for the right channel, and one for the ground.

TRRS jacks are typically used for headsets that have a microphone built-in.

TRS jacks are typically used for headphones that don’t have a microphone built-in.

2.5mm Headphone Jack:

2.5 mm plug

The 2.5mm headphone jack is not as common as the 3.5mm jack, but it can be found on some headphones, particularly older ones. The 2.5mm jack was introduced in the early 1960s and was commonly used on portable cassette players and radios. It’s smaller than the 3.5mm jack and requires less power to operate.

That is why it is called “Sub Mini” jack. It’s not as popular as the 3.5mm jack but they both are almost functionally the same, and the drawback is it’s not compatible with as many devices.

2.5mm jacks also come with two different Configurations:

  • TRRS (Tip, Ring, Ring, Sleeve)
  • TRS (Tip, Ring, Sleeve)

6.35mm Headphone Jack:

6.35mm jack
6.35mm (1/4″) Plug

The 6.35mm headphone jack is the largest of the three main types of headphone jacks. It’s also known as the “quarter-inch” jack because it’s about a quarter-inch in diameter. The 6.35mm jack was introduced in the late 19th century and was commonly used on phonograph players.

It is still used today on some professional headphones and audio equipment.

While it’s not as common as the 3.5mm jack, it offers superior sound quality because it can carry more power. The 6.35mm jack is also compatible with 3.5mm and 2.5mm jacks using an adapter.

There you have it! These are the three main and most used types of headphone jacks. Be sure to check what type of jack your headphones have before you buy them.

The Lightning jack is a proprietary connector that is used on some Apple devices. It was introduced in 2012 with the iPhone 5 and has been used on all subsequent iPhone models. The Lightning jack is also used on the iPad, iPod Touch, and some Beats headphones.

The Lightning jack is small and easy to use. It’s also less likely to break than the 3.5mm jack because it uses a sturdier design. However, the Lightning jack is not as universal as the 3.5mm jack and is not compatible with most other devices.

The Lightning connector has eight Conductor pins that are used for data and power transfer. For listening audio, it converts the digital audio signal into an analog signal and then sends it to the headphones. The connector is also used for charging the device.

Magnetic Jack:


The magnetic jack is a newer type of connector that is used on some headphones and charging cables. The magnetic jack is similar to the Lightning jack in that it is small and easy to use. However, the magnetic jack has a stronger connection and is less likely to come loose.

The magnetic jack uses two small magnets to create a strong connection between the headphone and the device. The magnets keep the connection secure, even if the headphone is jostled or pulled.

USB Jack (A and C)

When we talk about USB headphone jacks, we are referring to two different types of USB connectors: USB Type-A and USB Type-C. Many Headphones and other audio listening device manufacturers have now started using USB Type-C instead of 3.5 mm audio jacks.

USB Type-A Jack:

USB Type-A is the standard rectangular connector that is used on most USB devices. It is compatible with all USB standards and can be found on everything from printers to flash drives.

When it comes to audio, USB Type-A can be used to connect headphones and speakers to a computer or other device. The audio quality is typically very good because the USB connection can carry more power than a 3.5mm audio jack.

USB Type-C is the newer, smaller connector that is slowly replacing USB Type-A. It can be found on newer smartphones, laptops, and other devices.


USB Type-C is also becoming more common on audio devices, including headphones and speakers. It consists of 24 pins and can carry more data than USB Type-A. It is also reversible, so you can plug it in without having to worry about the orientation.
