Types of Headphones by Size

Types of Headphones by Size

There are different types of headphones by size and quality. Each of them differs from another.

1. Circum-aural or Over-Ear Headphones

Over-ear headphones typically have larger circular or ellipsoid earpads that cover the ears than on-ear headphones. They can provide better sound quality than on-ear headphones and block out more noise from your surroundings.

Many prefer these headphones because they offer a better overall bass response and sound quality. However, over-ear headphones are bulkier and may not be as comfortable when playing games or working on a computer. So, an ergonomic headband and earpad design are important to eliminate discomfort.

While earbuds are not as effective at blocking external noise as headphones, they can still produce high-quality sound.

Earbuds come in different shapes and sizes. In-ear earbuds are the most popular as they offer a discreet and secure listening experience.

1. Noise-Cancelling Headphones

There are 2 variants of noise-canceling headphones. Both cancel unwanted sounds from the environment, but the main difference lies in the cancellation quantity.

a) Active Noise-Cancelling Headphone

Active noise-canceling headphones are the perfect option to help you mute the noise and distractions. With ANC headphones, you can achieve silence because the opposing frequencies they create cancel out the frequencies of the background noise.

This is accomplished by using a microphone to pick up sound waves reflecting off the user’s ear and then using electronic circuitry to generate a wave with the same amplitude but an inverted phase, which cancels the unwanted sound.

These headphones can reduce external noise by 20 dB or more. Most also have Bluetooth technology, so you can wirelessly listen to music from your mobile phone or other devices.


  • Comfortable to wear for long periods, and many models come with wireless connectivity.

  • They are great for travel, as they can help minimize the effects of background noise on planes, trains, and buses.

b) Passive Noise-Cancelling Headphones

It is the most common type of technology that most headphones use. Active noise-canceling headphones use the opposite frequency of the surroundings to block out the noise, but passive noise-canceling headphones are more of hardware technology.

It uses particular types of ear cups that create an airtight seal to the user’s ear to prevent outside noise from coming to the ear. It is best for blocking a short time high frequency around you like sirens, crying of a baby, honking cars, etc.

  • Help to improve communication as they can provide more transparent sound quality than a standard phone.
  • Very comfortable to wear for long periods and can also help to reduce background noise.

3. Bone Conduction Headphones

These headphones use technology that transmits sound directly to your inner ear, bypassing the ear canal entirely. When wearing bone conduction headphones, the jaw and skull bones are penetrated by sound vibrations. The cochlea receives them there and transmits the sounds to the brain.

This type of headphones will give you a more immersive listening experience when you are struggling to hear music in noisy environments, and this might be the perfect choice for you.

They are usually less expensive than other headphones and don’t require batteries – making them ideal for on-the-go listening.

5. Jack

The headphone jack is a 3.5mm audio input/output port that connects headphones or earbuds to a device, such as a smartphone, tablet, or laptop. The jack is typically located on the side or bottom of the device.

How Do Headphones Work?

When you put on a pair of headphones, what you hear is transmitted through small speakers inside your ears directly into your brain stem, where it’s processed.

That means if you’re listening to music on headphones while working out, the sound will be transmitted directly to your brain without filtering through other noises.
