Why is one headphone louder than the other?

Chances are that this issue is caused by a few different factors. 

It can be a real nuisance, forcing you to constantly adjust the balance of your headphones. 

In this article, we take a look at why one headphone may be louder than the other and we’ll look at the causes of imbalanced headphones and how to fix them on a PC. Read on to find out more! 

Why is One Earbud Louder Than the Other? (5 reasons revealed!)

If you’ve ever noticed that one of your earbuds is always louder than the other, you’re not alone. 

This is a common issue that can be caused by a number of factors. The most likely reason for this discrepancy is that our ears are not the same size. 

Why is one headphone louder than the other?

This means that the earbuds are not always symmetrical, which can cause one to be louder than the other. The human ear is not perfectly round, so when you insert an earbud, it may not fit as snugly in one ear as it does in the other.

This can allow more sound to escape from the looser-fitting earbud, making it appear louder. Here take a look at how to measure headphones’ decibels.

1. The Headphones JackMight Need Some Cleaning

If you’ve ever noticed that one of your headphones is significantly quieter than the other, it might be because of a buildup of dirt and grime present in the headphone jack. As time passes, the headphone jack collects dust, and other debris, which can interfere with the sound.

To clean your headphone jack, start by using a can of compressed air to blow out any dust or lint. 

If that doesn’t work, you can try using a cotton swab dipped in rubbing alcohol to remove any build-up. Just be sure not to use too much rubbing alcohol, as it can damage the coating on the headphone jack.

2. Earbud Audio Signal Loss

If you’re using earbuds and one side is quieter than the other, it’s likely because of a signal loss. This can be caused by a bad connection, damaged wires, or loose hardware.

To fix this issue, first check the connection between your earbuds and your device. Make sure the jack is fully inserted and that there are no loose wires.

If the connection seems fine, try gently wiggling the earbuds to see if the sound quality improves.

3. Earbud Bluetooth Connectivity Issues

If you’re having issues with your earbud Bluetooth connectivity, there are a few things you can try. 

First, make sure that your Bluetooth device is compatible with your earbuds. 

Second, check to see if the Bluetooth connection is set up properly. 

Finally, make sure that your earbuds are charged and that the charging port is free of debris and turned on.

4. Varying Sound Levels

One common reason for this issue is that the audio source itself is unbalanced. This means that one channel is outputting more sound than the other, resulting in one headphone being louder.

To fix this, you can try adjusting the balance settings on your audio source. If your audio source doesn’t have balance settings, or adjusting them doesn’t help, another possible explanation is that the left and right channels are reversed.

This is an easy fix- simply swap the positions of the headphones in your ears

5. Earbuds are not firmly seated in the ears.

If your earbuds are not firmly seated in your ears, they may not be playing at the same volume. This is because the sound from the earbuds can leak out if they’re not snug enough.

Make sure to push them in until you feel a secure fit but not a hard push that can damage your ear canal, and that should help fix the issue.

What causes headphones to be unbalanced?

There are a few different reasons that headphones can become unbalanced. 

The most common reason is simply that the left and right channels of the audio signal are not equal. This can be caused by a number of different factors, including mismatched levels between the two channels, or an imbalance in the way that the signal is encoded.

Why is one headphone louder than the other?

Other potential causes include hardware problems within the headphones themselves or damage to the audio cable.

Or it could be the audio imbalance, have a look at it. 

The problem usually lies with one of your audio channels. When the signal is transported from the audio source to the speakers, it is split between the left and right channels of your headphones, resulting in the same amount of sound.

This signal, however, is unbalanced when there is a deficit in its flow.

Headphones typically use either mono or stereo audio channels. Mono means ‘one’, using one channel to send the signal, while stereo uses two channels to send the sound to the left and right channels.

Sound is split between channels when one channel is over- or under-utilized, creating the impression that your music is unbalanced.

There are several reasons why audio channels are unbalanced:

  1. When more current is directed to one speaker over another, frequencies are compromised, resulting in a seemingly unbalanced audio experience.
  2. There are specialized sound effects that can be found in the Control Panel that alter the perception of music coming from the sound card.
  3. The wrong output can cause unbalanced channels and sound. Nowadays, most commercial audio devices are adaptive and can detect the input device.

Use this left/right stereo test to check whether your headphones are in sync with your device.

  1. Go to the ‘Control Panel’.
  2. Select ‘Sound’ from the search results.
  3. Select ‘Properties’ from the right-click menu of your headphones.
  4. Go to the ‘Enhancements’ tab.
  5. Disable all sound effects by clicking the ‘checkbox’.

Check that your headphones aren’t plugged into a ‘mono’ jack

The wrong jack could be a problem when it comes to unbalanced headphones. it might b e possible that you are using a mono output audio device. you can also call it mono jack.

To fix this, follow these steps:

Ensure that the headphones are plugged into a headphone port.

The device will have a headphone port labelled ‘headphones’ or a sign of a headphone icon, which means your headphones will sound equally and their channel will be stereo.

Make sure not to plug your headphones into an ‘earphone’ jack.

Don’t plug your headphones into an ‘earphone’ jack.

Plugging headphones into an earphone jack will only create sound in the left earphone. You Should always make sure that your headphones are plugged in the headphone jack instead of earphone jack.

How to balance sound in headphones on an Android device

Accessibility settings might be to blame for a louder earphone on your Android device. These are similar to the sound settings on Windows devices, which enhance the listening experience by assigning the audio to mono or stereo channels.

Try these steps to see if these settings have been enabled:

Adjust headphone balance or enable ‘Mono Audio’

  1. Go to ‘Settings’.
  2. Choose ‘Accessibility’.
  3. The slider should allow you to shift speaker balance left or right.
  4. Alternatively, you can try the ‘Mono Audio’ feature. This will reproduce sound equally via both channels, will allow equal playback from both earphones but removing the stereo effect.

By adjusting the left-right volume balance or enabling mono audio in the accessibility settings on your Android phone, you can balance the audio of your headphones.

Changing these settings won’t increase the volume of your Android headphones. If they have a volume limiter, you’re better off buying a new pair.


How do you fix headphones with one side louder than the other?

To fix headphones with one side louder than the other, open the ‘Accessibility’ app on your phone and navigate to ‘Settings’. Under ‘Accessibility’, you will find a slider to shift speaker balance either left or right. If this doesn’t work, you can also check the ‘Mono Audio’ feature.

One of the two AirPods might be turned up louder than the other. To fix it, first unlock your iphone then go to Settings and then Accessibility > Audio/Visual. There you will see a slider that lets you adjust the sound balance between the left and right AirPods.

Why is my headphones so loud at 1%?

Headphones work by amplifying the audio signals they receive. When you play music through your headphones at a low volume, the speakers in the headphone are turned up to a higher volume than usual. This causes them to be 1% louder than they would be at 100% volume.

Why are my earbuds unbalanced?

Earbuds are not meant to be worn in one specific way. They should be rotated so that the ear canal is facing the speaker. Try it this way: Pick up the earbud by the wire and hold it so that the earpiece is facing down. Then rotate it so that the earpiece is pointing towards your ears and let go.

If your earbuds are not inserted properly, they will feel unbalanced.
