How to fix earphones one side is quieter? Don’t throw away those earphones just yet! We came up with a list of the possible reasons why one headphone is louder than the other and of course, tips on how to make your headphone louder. Try the tips out before considering buying a new pair.

Don't immediately discard your earbuds or headphones as these may not be the one at fault. If you look at professional DJ, sound engineers, and music producers' headphones, you'll notice that one side is louder than the other. This is so because sound specialists need to listen to all the aspects of sound. Usually, one side is louder and may produce the beats while the other side is quieter and may produce the vocals.

But if you think that this is not a mixing issue and you’re just using regular earbuds, use another device to play the audio file you were listening to before. If you find that the issue has remained then you may be listening to audio at 8D. But if the issue is resolved, then the problem is with the device or audio source.

If the sound is fine but there is obvious audio signal loss then you can end up having good audio from one ear and poor audio from the other. Usually, this happens if you have a very long audio cable. The longer your cables are, the farther audio has to travel. There is also higher signal resistance and thus, you’ll end up getting very weak audio in one of your earbuds.

Another possible scenario is that you’re playing music from a portable music player that has a line remote. The line remote must be disconnected from the music player to improve the volume on your headphones or earbuds.

If you’re using wireless or Bluetooth earbuds and you’re wondering why is one earbud louder than the other then you might be facing connectivity issues. Sometimes, wireless earbuds or headphones may disconnect from the audio source or device through Bluetooth and this can lead to one earbud being quieter or louder than the other. In some cases, pairing issues may also lead to imbalanced audio. This holds for all wireless audio listening devices such as wireless or Bluetooth headphones, earbuds, Airpods, and headsets.

Another reason why problems like headphones louder in one ear happen is a computer or smartphone settings problem. Sometimes, one of the earbuds is quieter or there is too sound or there is a very loud sound in both ears and this could be due to the settings on the media player of your computer or smartphone.

But before anything, you must first check if the problem is from the headset or earbud. Do this by connecting your device to another computer or smartphone. Check if it is working okay and if it does, the problem comes from your device media player.

If you’re using an Apple or an iPhone, any similar issue may be due to incorrect left and right balance. You can check this by going to the device’s Settings under the General tab > Accessibility > Hearing. The channel balance must be in the middle.

If you’re on an Android smartphone, go to Home > Headphone Settings to check the headphone volume settings. You may also access this from the Google Assistant app. From the app, click More > Settings > Headphones. Now you can tweak your headphone volume settings.

To check this setting on your PC or Mac computer, go to the audio settings. But if you have an external sound card made by a third party, bypass this sound card by disconnecting the audio connection and connect this to the motherboard sound card. If the issue is resolved, you may have a faulty third-party sound card.

If you are using a Windows PC, here are some ways to access volume settings.

• Locate the sound icon from the lower right corner of the screen. Right-click and choose the Open Volume Mixer and check the volume level and the headphone settings.
• Locate the Start Menu and type Sound Settings. You may now check the sound volume from here. Go to Device Properties to manage devices like audio devices connected to the PC. 
• From the same page, go to App Volume and Device Preferences. You may now check the headphone volume here.

If you are a MAC user, here are ways to check your device settings.

• Go to Apple Menu, go to System Preferences and click Sound
• Go to the Output tab and select Headphones. If you can’t find the Headphones option, then your headset/headphone is not connected to your computer.
• Adjust the volume and select the balance; this must be in the middle of the Left and Right slider.

If the issue continues, restart your Sound Controller by going to the Applications > Utilities > Activity Monitor. Choose coreaudiod to access the Core Audio controller. When you click the coreaudiod and exit this by clicking X, this application will exit and the sound controller will immediately restart.

The audio file refers to the type of file that you’re trying to listen to. If the file you’re trying to listen to has been recorded or possibly transcoded then the audio may sound lower. Usually, if the audio file is the culprit, the sound will remain low or very low no matter how you increase the volume.

Devices have different outputs; mono and stereo outputs. Mono uses only one channel to produce sound while stereo uses two or more. If you are using stereo earbuds or headphones and you are playing a stereo source you can hear different sounds from various channels from the left and right speakers.

If your device is mono, the audio will only be heard from the left speaker or the left side of the headphone as this is the single sound output. To prevent this, ensure that the audio source is capable of playing stereo outputs.

Check the label on the jack to find out if you can use it for mono or stereo. If the jack is made for earphones, the label will say mono, meanwhile, a jack with stereo outputs is made for headphones.

Wired headphones may start to produce problems when the wires start to bend, open, and fray. Damage to the wires near the jack, plugs, in-line controls can also lead to skipping, loud noises, and low audio from the earbuds.

Somehow, no matter how you prevent bending, warping, and fraying, these will ultimately happen. But to preserve the life of your earbuds, until you can find a better quality pair, take good care of it by not pulling and grabbing the wires. If you must remove the earbud or headphone from your device, pull the wire from the jack. Keep these securely in a separate bag or pocket and never with your keys, spare change, or pens.

If you checked everything and you still have one headphone louder than the other then the headphone you’re using may have some kind of defect. A headphone with a factory defect won’t sound good and may even show all kinds of symptoms too. If this is a newly-purchased headphone, then check the manufacturer’s warranty or store warranty. You may still qualify for a return if the earbuds are still under warranty.

Sometimes, the problem might show up after a few weeks or months of use therefore, it's always best to buy products that are covered with a longer warranty. If you're unsure about the warranty of your earbuds, earphones, or headphones, contact the manufacturer or the store where you purchased it. 

Now that you know why is one earbud louder than the other and how to remedy this problem, you don’t need to throw away a problematic pair plus, you’ll save money in the long run.
