I always recommend researching the thing you want before buying it. That’s how I’ll be helping you today, I’ll tell you everything that you need to know about the headphone jack size.

The usual headphone jack size is 3.5 mm, this is the model that most smartphones and PCs use. Older phones and amplifiers use a different size, we’ll cover that in a minute.

The 3.5 mm headphone jack

I’m sure most of you have seen what this headphone jack looks like. If you’ve ever used a smartphone with headphones, you know what it looks like.

Now, the 3.5 mm isn’t the length of the jack but the size of the diameter of the jack. This is the size that the standard headphones use, regardless of what you connect the headphones with.

The standard headphone jack can differ only in the number of connectors it has, by that I mean, black rings around the jack. 2 rings around the jack means that you can only listen to audio, 3 rings means that you can use the microphone too.

Older headphone jack size

Before smartphones came into existence, many phones used a 2.5 mm headphone jack. Today, it’s hard to find a device that uses the 2.5 mm jack.

However, if you have a device made 10-15 years ago, the chance is, you need a 2.5 mm jack. You can see that the port is smaller than the one on your smartphone.

If you want to pair that device with new headphones you can buy an adapter that changes your 3.5 mm jack into a 2.5 mm jack. I did this with my old Sony Walkman, had fun with it.

Stick around if you want to use your headphones with amplifiers.
