Ruling Out Phone or PC Settings
Just like other audio problems like headphone static, when headsets are only playing in one ear, many quickly assume that their earphones are broken. So they start shopping around for a replacement or looking for spare headphones at home.
But before discarding your earphones or attempting a repair, make sure that the issue doesn’t lie with your audio source.
Rule out the possibility that you’re hearing out of one headphone due to your audio settings or a temporary device malfunction that can be easily resolved. Follow the steps below to check whether the problem is being caused by your phone, laptop, or PC.
1. Try another pair of earphones
The first step is to get a pair of perfectly working earphones and connect them to your device. If they are working fine, then you know that the problem truly lies with your headset. In this case, follow the tips below for fixing wired and Bluetooth headphones. But if the functioning headset also starts playing only in one ear, you need to check your device’s audio settings.
2. Restart the device
Another simple fix you may want to try is restarting your device. This may prove especially helpful if the issue occurs right after a software update.
After restarting your phone or PC, check if you can hear out of both earbuds. But if the headset is still playing in only one ear, start checking your device’s audio settings.
3. Check the settings
Headsets may play only in one ear depending on your audio settings. So check your audio properties and make sure that the mono option is turned off.
In addition, make sure that voice levels are balanced on both earbuds. You can check this by clicking on the Sounds icon on your computer, going to Levels, and then selecting Balance. The voice levels must be equal on both sides of your headset.
4. Clean the headphone jack
People bring their phones everywhere–from their bedrooms to the rugged outdoors. Eventually, lint and dirt can get trapped in the headphone jack and affect the audio output. This causes a loose connection between your headphone port and the jack.
If your headset plays only in one ear when plugged to your device but works just fine in other gadgets, consider cleaning your phone or PC’s headphone jack. Carefully loosen the dirt with the pointed tip of a brush toothpick, then use the brush side to scoop these out.

Diagnosis: Damaged or disconnected wire near the jack
When in a hurry, some users yank out their headset’s jack from their mobile phones and laptops. Others disconnect their headsets from devices by tugging at the cord instead of pulling from the plastic base. This can also result in a bent headphone plug.
These habits can damage the wires near the headset’s jack. Over time, your headphones may start working only in one ear whenever the cords are twisted or bent. To resolve this, follow the steps below.
How to fix damaged wires
- Use a knife or cutter to slice through the plastic protective base around the earphone jack as well as the cord near it.
- Locate the section with the broken wires and cut it off.
- Remove the plastic cord around one end of your headset cord.
- Use a match or lighter to briefly burn off the wire’s insulation.
- Solder the wires to the earphone jack following the illustration below.
- Cover the newly joined section.
Diagnosis: Shorted wire
Another reason for headsets only playing in one ear is a shorted wire. This issue usually happens when earphone cords are always tangled or wrapped improperly. Follow the steps below on how to locate and fix shorted earphone wires.
How to fix shorted wires
- Plug your headphones to your device and play an audio or video file.
- Locate the short by bending the earphone cord every half inch. Continue doing this until you start hearing sound coming off both earbuds.
- Remove the damaged portion of the wire.
- Get the remaining sections of the earphone cord. Slice through both tips of the plastic cord to expose the wires.
- Separate the copper wires (ground wires), insulation (white wires), and the colored wire. (The colored wire will be red if you are repairing the headset’s right portion, or green or blue if you’re working on the left section.)
- Cut the insulation wires. Meanwhile, twist the copper wires to keep them together.
- Use a match or lighter to briefly burn off the enamel at the tip of the colored wires.
- Join the colored wires by twisting them together. Secure these with an electrical tape.
- Link the ground wires in the same way and wrap an electrical tape around these as well. Ensure that the ground wires do not touch the colored wires.
- Put an electrical tape around this newly linked section.
Diagnosis: Faulty wiring within defective earbud
Sometimes, a loose or broken wire can cause your earbuds to play only in one ear. Once you’ve determined that the issue isn’t caused by a broken or shorted wire along the cord, follow the steps below to open and fix the earbud.
How to fix faulty wires inside earbuds
- Open the earbud casing using a small flat-blade screwdriver. You can also detach your nail clipper’s lever and use it to pop the earbud’s front case or ear tip open.
- Do not pull the case to further open the earbud–doing so can further rip the wires if attached to the front case. Instead, push the cord up through the earbud’s upper housing. This will shove the front case and expose the internal components.
- Resolder the loose wire and let it cool before testing the headphones.
