Let’s figure out what is happening and how to fix it!

Why Does Only One Side of Headphones Work on a Computer?


It can be a complete headache when your headphones work only on one side when connected to your computer, and some users even change their computers to fix the issue.

But what are the problems and how to solve them?

Simple solutions to this problem!

Let’s discover why only one side of headphones works on a computer and some most effective tips to resolve this issue.

1. Damaged or disconnected wire near the jack

            If you’re getting a crackling noise in the left or right speaker, it might be because of a damaged wire near your headphone plug.

This type of damage is usually caused when the cord is detached from the device or twisted and repeatedly bent over time. 

Here are seven easy steps you can take to fix it:

1. Cut off the damaged section of the wire using a knife or cutter.

2. Remove the plastic cord around one end of your headset cord.

3. Burn off the wire’s insulation using a match or lighter.

4. Solder the wires to the earphone jack following the illustration below.

5. Make sure to connect the correct wires to their corresponding section on the earphone jack.

6. Make sure there is no exposed metal on the wires, and then secure them with electrical tape.

7. Test your headphones to see if they are working.

2. Earbuds with Faulty Wiring

            These are the steps you will need to take if your earbud only works in one ear.

First, check to see any damage to either wire inside your headphone’s cord. If you find damage, the issue may be with the wiring of your cable instead of faulty wires within your headphones.

If both wires seem okay, but only one side works, try opening up your defective earbuds and fixing what’s broken inside.

You can do this by using a small flat blade, screwdriver, or the nail clipper lever as an opener.

Once you have opened up the casing of your headphone, use tweezers to remove any loose pieces of wire found around the speakers.

3. Shorted wires

            Using headphones is a great way to listen to music and watch videos on your device, but only when they’re working correctly.

But another common issue with headphones is a shorted wire, which is usually caused by the wire being tangled or wrapped improperly and fixed by following a few simple steps.

To locate a shorted wire, bend the headphone cord every half inch and listen for sound coming from both earbuds.

If you can hear sound coming from both sides, you know the problem lies somewhere in the cord. It is necessary to remove the damaged section of the cable and replace it with a new cable.

You should now be good to go!

If you are still not completely pleased with your headphones and need to buy other headphones, you can choose one for yourself among these ten best headphones that don’t leak sound.

4. Needs Reset

If your Bluetooth headphones are not working, even though they are fully charged, the problem may be with the internal wires.

You can try repairing them yourself using a soldering iron. If that doesn’t work, you may need to reset the headphones.

To reset the headphones, hold down the power button for 10 secs. Release it and then press it again for 10 secs. 

Let go and wait until the LED light starts flashing blue and red before connecting them to your device. If the headphones still don’t work, try repairing them again or contact customer service.

Bluetooth headphones offer a great way to listen to music and take calls without having to worry about getting tangled up in wires. 

However, if something goes wrong with the internal wires, you can fix the issue by following the above steps.

5. Halfway Point – a Problem

            You may have a halfway point issue if you’re having issues when you’re using wireless mode but the headphones work when the aux cable jack is plugged in.

Typically, these issues occur when one of your headphone speakers becomes dysfunctional due to a mechanical trigger stuck halfway. 

Here are the tips through which you can solve such a problem.

  • Plug the aux cable into the jack port, then remove it.
  • Repeat step one under multiple angles until the mechanical trigger is firmly positioned again. 
  • You can check if the problem is resolved by testing your Bluetooth headphones. 


As you understand why you face the problem with your headphones that work on only one side while using it on your personal computer, you also learned how to fix those issues. Make sure to apply these tips to solve the issue before taking it back to the shop or getting worried for any reason.
