Why is only one earbud working? If you’ve ever put on your wireless earbuds only to realize that sound is coming from just one side, you’re not alone. This is a common issue with AirPods, Galaxy Buds, JBL, Sony, and other brands. The problem could be due to a low battery, a Bluetooth glitch, dirt blocking the speaker, or even incorrect audio settings.
The good news? In most cases, this can be fixed with simple troubleshooting steps. In this guide, we’ll cover the most common reasons why only one earbud is working and provide easy solutions to restore sound to both earbuds.
Common Reasons Why Only One Earbud is Working
Many users face issues with one-sided audio in their wireless earbuds. The problem can stem from something as simple as a low battery or as complicated as a hardware malfunction. Here’s a summary of the most frequent causes:
- Low Battery – If one earbud runs out of charge faster than the other, it might not work properly.
- Bluetooth Connection Issues – A weak or unstable connection can cause one earbud to disconnect.
- Dirt & Debris Blocking Sensors – Earwax, dust, or dirt can block charging connectors or audio sensors.
- Mono Mode Activated – Some earbuds have a setting where only one earbud plays audio.
- Software Glitch or Firmware Issue – Outdated firmware or system bugs can lead to connectivity problems.
- Hardware Damage – If an earbud has been dropped or exposed to water, it may have internal damage.
How to Fix the One-Sided Earbud Issue
1. Check the Battery Level

- Place both earbuds in the charging case and ensure they’re properly seated.
- Let them charge for at least 10-15 minutes before testing.
- If one earbud doesn’t charge, clean the charging connectors with a dry cotton swab.
2. Reset Your Bluetooth Connection

- Turn off Bluetooth on your device.
- Forget the earbuds from the Bluetooth settings and pair them again as a new device.
- If using an iPhone or Android, restart your phone before reconnecting.
For AirPods Users:
Go to: Settings > Bluetooth > Tap “Forget This Device” > Reconnect AirPods.
3. Clean Your Earbuds and Charging Case

- Gently wipe the earbud mesh and charging pins with a soft, dry cloth or a small brush to eliminate dust.
- Utilize compressed air to dislodge any tiny particles from the speaker grill.
- For tougher grime, apply isopropyl alcohol to a cotton swab for effective cleaning.

4. Turn Off Mono Mode (If Active)

Some earbuds feature a Mono Mode that restricts sound to just one earbud. Here’s how to verify:
- Access your device settings (look under Bluetooth or audio settings).
- Find the option labeled “Mono Audio” or “Single Ear Mode” and turn it off.
- Test both earbuds to ensure they function together once more.
5. Update Firmware and Software

- Many earbuds come with a companion app (like AirPods, Galaxy Buds, JBL) for firmware updates.
- Look for updates and install the latest software to resolve any issues.
- Restart the earbuds after completing the update.
6. Reset Your Earbuds to Factory Settings

If all else fails, reset your earbuds to default settings. This will erase any bugs or incorrect settings.
How to Reset Most Wireless Earbuds:
- Place both earbuds in the charging case.
- Hold the reset button on the case for 10-15 seconds until the LED flashes.
- Remove from Bluetooth settings and reconnect as a new device.
Note: Each brand has a different reset method. Check your manufacturer’s manual if needed.
7. Check for Hardware Damage or Contact Support

If one earbud is still not working, it may be due to hardware damage. Here’s what to do:
- Check for physical damage (water exposure, cracks, loose connections).
- Try using the earbuds on a different device to rule out device-specific issues.
- If under warranty, contact customer support for a replacement or repair.
Final Thoughts
If you’re experiencing sound from just one earbud, there’s no need to worry! Often, a quick reset, a bit of cleaning, or re-pairing via Bluetooth can resolve the problem. However, if these steps don’t help, it might be time to think about getting a replacement or seeking professional repair services.
