Proper Diagnosis of the Situation With Tests

Before we teach you how to fix your defective earbud with DIY solutions, you need to first examine the overall situation with a proper diagnosis.

Test 1: Change Device

Yes, you need to decide – are your earbuds really the main culprit here or your source device?

By “source device,” we mean the device that is actually delivering the audio. It could be your smartphone, computer, or tablet.

First things first, put another source device to the test. Connect your earbuds to a different smartphone or a laptop and then play some music.

If your earbuds sound great and are functioning properly when connected to another device, the earbuds aren’t defective.

However, if the earbuds still only work on one side no matter which device you connect them to, that means your earbuds need some serious troubleshooting.

Test 2: Change Music Channel

There’s another test you could try. If you listen to music on Spotify with earbuds, change the application and play music from another app.

Although this isn’t a legit cause of earbud problems, it may certainly occur on occasions.

One Earbud Not Working: Possible Reasons With Solutions

After you’re confirmed that it’s the earbuds that are malfunctioning not the source device, here’s what to do. You should diagnose your earbuds to check whether it has any of the problems below and then fix it with our tips.

Only one bluetooth earbud works at a time - Possible Reason

Reason #1: Connection Interference

Interference from other wireless devices or obstacles between the earbuds and the source device can disrupt the Bluetooth connection, leading to audio playback in only one earbud.

How To Fix: Ensure Clear Line of Sight. Make sure there are no obstructions between your earbuds and the device they’re paired with.

Also, stay away from other electronic devices that could be causing interference, such as microwave ovens, cordless phones, or Wi-Fi routers.

Reason #2: Bluetooth Pairing Issues

Incomplete or improper pairing can result in audio playing in only one earbud. This can happen especially when you’re in a rush when pairing your Bluetooth earbuds and mess it up.

How to Fix: Simply reset your earbuds. You need to click on ‘Forget’ then ‘Re-Pair’ to delete the earbuds from your device’s Bluetooth settings and then re-pair them.

Here’s how you can reset any Bluetooth earbuds:

Step 1: Put them out of the case and turn them on.

Step 2: Connect the case to a power source.

Step 3: Put the earbuds back into their case.

Step 4: Press and hold the control panels for 6 seconds at the same time.

Step 5: They should be reset to factory default now. You will be able to connect them to your device again.

Reason #3: Battery and Charging Problems

Uneven battery levels or inadequate charging can lead to one earbud not working properly.

How to Fix: Charge both the earbuds if the battery level is low. Always ensure that your earbuds are properly charged before using them. Place them in the charging case and ensure the case itself is adequately charged.

You should also be mindful of their battery life. If one earbud’s battery constantly drains faster, there might be a hardware issue. Contact your manufacturer’s customer support for assistance or get it checked by a professional.

Reason #4: Audio Balance Settings

The audio balance settings on your device might be configured incorrectly.

How to Fix: You need to check audio balance. Go to your device’s audio settings and make sure the audio balance is set to the center.

Reason #5: Physical Damage or Debris:

Did one of your earbuds recently fall from your hands while going down the stairs? Note that physical damage to the earbuds or dirt and debris in the audio output can affect audio playback.

How to Fix: You should carefully examine both earbuds for physical damage. See if any part looks discolored or broken. Also, check for clogs in the audio output area.

Lastly, if you dust particles or debris in the audio output area, gently clean it using a soft, dry brush or compressed air. Don’t try to use soap and water or involve any sort of liquids. That may do more harm than good.

Reason #6: Software Updates:

Often, outdated firmware or software can cause connectivity and audio playback issues. Again, this is not very common but a possible reason.

How to Fix: Check for Updates. Check the manufacturer’s website or app for any available firmware or software updates for your earbuds. If updates are available, follow the manufacturer’s instructions to update your earbuds.
