If the single side of headphones is functioning, numerous possible causes. This guide will help you troubleshoot the problem and fix it quickly!


The most common reasons for one side of headphones not working are:

  1. Ensure the headphone socket is completely injected into the audio port on your device.
  2. The headphone jack is dirty or damaged. Use a cotton swab to clean any dirt or debris from the jack, and try plugging the headphones into another device to see if they work.
  3. The audio port on your device is damaged. If the headphones work on other devices but not your current one, the audio port may be damaged and need to be replaced.
  4. The speakers in your headphones are defective. If none of the above solutions work, the speakers in your headphones may be defective and need to be replaced.

Easy Fixes

If you’re having problems with one side of your headphones, there are a few easy fixes you can try before taking more drastic measures:

  1. Make sure the headphone plug is fully inserted into the audio port.
  2. Clean any dirt or debris from the headphone jack using a cotton swab.
  3. If headphones work on another device, the problem is likely with your current device.
  4. Some devices have a separate setting for headphones and speakers. Make sure the headphones are set as the default audio output.

If none of these solutions work, the problem may be with the headphones themselves, and they may need to be replaced.

The headphones are plugged in, but the sound only comes from one ear.

This happens when either the headphones or 3.5mm audio jack is broken. Firstly check that your software is up-to-date, and then test another pair of headphones to verify that it’s not just your own set that has an issue. If other headphones work, the problem is with your original “broken” pair and two different solutions depending on how much work you want to put into repairing them. The easier way is to switch the left and proper channels by following this guide (this method should work for most phones). Another solution requires soldering, which will be explained below.

Only one headphone of a set plays sound.

Solution 1:

Switch the audio channels on the broken pair. Test with another working pair of headphones to verify.

Tools needed:

Small Phillips #0 screwdriver, soldering iron, and solder

Repair time:

10-15 minutes

Special notes:

You can choose to switch the left and proper channels completely or invert them (so that what was in the left ear is now moved to the right). The latter method only costs slightly less work but will be harder for other people who might use your headphones after you fix them. Solder connections should be made on both sides of the 3.5mm jack to prevent short-circuiting (look for pictures on Google if you are unsure).

Solution 2:

Open the broken pair, solders wires to the speaker itself, and reassemble. Only attempt this method if Solution 1 does not work, or you want to switch channels.

Tools needed:

Small Phillips #0 screwdriver soldering iron and solder, Dremel with cutting disk  or small metal saw, hot glue gun (optional).

Repair time:

Twenty minutes minimum, up to an hour depending on experience with electronics.

Special notes:

Be extremely careful when working inside devices as certain parts can be susceptible. If this is your first time repairing headphones, I’d recommend practicing with an old pair that you don’t mind destroying before trying it on the “broken” set. Ensure the wires are soldered to the correct points on the speaker and do not allow any solder to flow onto the jack’s contacts. Also, use a little hot glue around the housing edges to keep everything in place and prevent short-circuiting once it is reassembled.


  • Why are my headphones not working on one side?

There are a few potential reasons why your headphones may be malfunctioning on one side. It could be that the wire has been damaged, the speaker in the headphone is not functioning correctly, or something is blocking the sound from coming out of the headphone. If you have checked all of these potential causes and found that none of them is the problem, the issue is likely with the headphone jack on your device. Try using headphones with a different jack to see if that fixes the problem. If it does, it is likely that your device’s headphone jack is damaged and needs to be repaired or replaced.

  • What can I do to fix my headphone jack?

If you have tried using headphones with a different jack and the problem persists, it is likely that the headphone jack on your device is damaged and needs to be repaired or replaced.
