It can be quite frustrating when one side of your headphones stops producing sound. Hearing only from one ear can leave you feeling off-balance, and sometimes you'll miss audio effects or instruments that should be moving between the left and right sides. The good news is that there are several ways to fix this issue. Today, Mytour will guide you through the steps to repair headphones with no sound in one ear.
Steps

Check to ensure the headphones are properly connected. If you're using wired headphones and notice one side isn't working, the first thing to do is make sure the connection is secure. Unplug the headphones from the jack, reconnect them, and test again.

Verify the stereo balance. If you're using a smartphone or computer, go to the audio settings in the menu and check that the stereo balance is centered. It should be evenly distributed between the left and right sides, without being skewed to one side. For external audio devices like a sound receiver, check the settings on the device itself to make sure the stereo balance is in the center.

Check if you're in mono mode. Mono audio mode sends the same sound to all speakers, whereas stereo audio transmits different sounds from the left to the right speakers. When checking your device's audio settings, make sure that it has the option to toggle between stereo and mono modes. If it does, ensure that stereo mode is selected, not mono.

Unpair and pair again for Bluetooth headphones. If you're using Bluetooth headphones, try unpairing them by turning off Bluetooth on your device. Then, reconnect the headphones and check if the issue is resolved.

Restart your device. If you're using a computer, smartphone, or tablet, try powering off the device and then turning it back on. This action can help resolve temporary software issues.

Try different headphones. If the same problem occurs with multiple headphones, the issue might be with the headphone jack. In this case, clean the jack. If cleaning doesn't help, it may be time to get your device checked.
- To clean the headphone jack, power off the device. Dip a cotton swab in warm water, wring out excess water, and twist it so the cotton fits tightly around the stick. Gently insert the swab into the jack and twist to remove any dirt. Repeat this with a dry swab. Wait for a few hours and check if the issue is fixed.
- If the headphone jack issue occurs on a computer, smartphone, or tablet, it could be due to a virus. Run a virus scan. If necessary, back up the device and perform a factory reset.

Dirty headphones can also affect performance. Inspect the side of the headphones that isn't working to check for earwax or dirt buildup. If the headphones are dirty, clean them using a small brush or a vacuum cleaner with a specialized nozzle. You can also dampen a cotton swab with warm water or alcohol-based cleaning solution to clean the headphones. Make sure to wring out the swab before using it. Then, dry the headphones with a clean swab before using them again.

Check for water damage. Headphones are often exposed to sweat, rain, and spilled liquids, which can lead to malfunctions. If you suspect water damage, place the headphones on a windowsill or in front of a fan to dry. If possible, remove the ear tips or any other removable parts to help the internal components dry faster. Let the headphones dry for about 72 hours, then reassemble them and check if the issue is resolved.

Inspect the cable for damage. If your headphone cable is tangled, carefully untangle it and straighten it out. Plug the headphones into your device and play audio. While the audio is playing, feel along the cable, twisting it to check for any breaks or exposed wires. Pay special attention to the area where the cable connects to the headphone jack. If you notice sound when testing a specific section of the cable, here’s what you can do:
- If you locate the damaged part of the cable, unplug the headphones from the device. Then, using wire cutters, carefully remove the outer insulation to reveal the inner wires. Be cautious not to cut into the wires themselves. If the internal wires are tangled, untangle them. In case the wire is severed, reconnect the wires by twisting or soldering them back together. After the repair, test to see if the issue is fixed. If the headphones work fine, wrap any exposed wiring with electrical tape.
- If the cable is damaged near the connection to the headphone jack, you may need technical support. A broken wire at this point might require soldering. Alternatively, if you have a spare 3mm jack cable, you can try cutting the cable and splicing it with the new jack.

Take the headphones to a professional repair shop or buy new ones. If you've tried everything and your expensive headphones still aren't working, it may be time to consult a professional technician. For budget headphones, however, replacing them with a new pair might be a more practical solution.
