  • Reset & Charge: Perform a reset on your earbuds if necessary and ensure each earbud has enough charge to function properly.
  • Clean Contacts: Address charging issues by cleaning the charging contacts and pins for a better connection.

How To Fix: JBL Earbuds One Side Not Working

If you’re facing the all-too-common plight where your JBL earbuds are only working on one side, fear not! Many people have encountered this issue, and there are several fixes that have worked.

  • The first solution is to restart your earbuds. This might seem too simple, but it often solves the problem.

  • Disconnect the earbuds from your electronic device, turn off the earbuds completely, and put them back in their case, making sure to close the lid. This process resets the connection.

If this doesn’t work, consult the user manual for your specific JBL model. It provides detailed instructions on how to manually reconnect your earbuds.

  • In some cases, the left and right earbuds are not synced with each other. TWS JBL earbuds operate with a master-slave principle—usually, the right is the master, and the left is the slave.

To sync them, follow the quick instructions in the user manual.

The procedure for re-syncing varies across models, but generally, you need to disable Bluetooth on your phone, forget the earbuds from your list of paired devices, and then reconnect them.

  • This is achieved by pressing the button on each earbud three times. For some models, you might need to do this simultaneously.
  • Start with the left earbud, pressing its button for 2 seconds until the LED flashes blue and white, then repeat with the right earbud.
  • When they start flashing slowly, it indicates they are paired.

How To Sync Left And Right Jbl Earbuds

Syncing JBL earbuds can be a bit tricky, especially when they are not working in harmony. Many JBL models follow the same resync procedure, although some might be different.

Let me share a specific sequence that worked for me.

  • First, take the LEFT earbud (usually the slave) and turn it on by pressing the button for 2 seconds. You’ll know it’s turned on when the LED flashes blue and white.
  • Then, repeat this with the right earbud. Once both start flashing slowly, they’re paired and synced.

For certain models like the Live Free NC+ TWS, Reflect Mini NC, and Reflect Flow Pro,:

The process involves putting them back in their charging case and closing the lid.

Then, disable Bluetooth on your phone, take the earbuds out of the case, and press the button located at the back of the case.

For the JBL Live 300TWS and JBL Club Pro+ TWS, you’ll find the button at the bottom.

A double press (2x) should start the process, and you’ll see a series of LEDs flashing in orange, pink, or another color for a few seconds, indicating they are synced together.

If you receive a notification to update your earbuds, it’s recommended to follow the instructions.

Typically, you’ll need to put them back in the case with the lid open to allow the update process to happen quicker.

Reset The Earbuds

If syncing doesn’t resolve the issue, a reset might be necessary. Resetting is more invasive than syncing but definitely worth a try before anything else.

Resetting brings the earbuds back to factory defaults, erasing all saved pairing information and custom settings within the app.

Resetting Jbl Earbuds Manually

Different JBL earbud models follow different reset procedures. It’s essential to consult the manual or support website for your specific model to find the exact instructions.

For JBL, Tune, 115TWS, 125TWS, 225TWS, Ghost, Free, II, 215TWS, 120TWS, 220TWS, X. , you may follow these steps:

Preparing for Reset

Begin by forgetting the earbuds from your phone. It’s crucial to disable Bluetooth on any devices they were previously paired with.

  • This helps ensure a clean slate for reconnection.

Now, place your earbuds back in the charging case. It’s important to make sure the case has enough juice to charge your earbuds; otherwise, the reset might not be effective.

Open the lid before taking them out, then connect the case to a power source.

Many people make the mistake of doing this without connecting the USB cable, but ensuring a stable power supply is crucial.

Executing the Reset

  • Now, press and hold the button on the RIGHT earbud for 5 seconds. You’ll know the reset is successful when the LED lights turn off and then back on.

Congrats, you’ve just completed the reset.

Through this process, we’re not just hitting a virtual “refresh” button; we’re recalibrating the earbuds’ internal settings, often resolving the issue of one side not working.

It’s a simple yet effective way to breathe new life into your JBL Earbuds.

After the Reset
  • Once you’ve completed the reset, it’s essential to pair your earbuds again with your device.

This fresh start often resolves the issue of one side not working, bringing back the balanced sound that JBL earbuds are known for.

Reset JBL Earbuds Through The JBL Headphones App

If your JBL earbuds are not working on one side, resetting them through the JBL Headphones app can be a quick fix.

  • First, ensure your earbuds are recognized by the app.
  • Open the app, scroll down, and tap on ‘Support,’
  • then select ‘Reset to Factory Settings’.
  • You’ll need to confirm your choice to reset.
  • Typically, the earbuds should go into pairing mode automatically after resetting.
  • If this doesn’t happen, you might have to initiate it manually. For specific instructions, you can refer to the list of user manuals for popular models available in the app.

Clean The Earbuds

  • Regular cleaning should be part of your routine, as over time, ear wax, gunk, and dirt can build up on the ear tips and the mesh that protects the speaker drivers.

If not cleaned, this build-up can penetrate through, clogging the mesh and making the sound much quieter than it should be, leading you to think one side is not working.

  • To clean your JBL earbuds, gently remove any dirt or accumulated ear wax from the mesh and ear tips.
  • You can use a cotton swab, tweezers, or a paper clip for this task, being careful not to penetrate too deeply into the earbud’s space.
  • If you find dirt stuck behind the mesh or on the charging pins, a soft brush or a slightly damp cloth can be used.
  • In extreme cases where the mesh is fully clogged, you may need to gently remove it for thorough cleaning, but be cautious as this is a delicate task.

Important Reminder: After using WD40, avoid placing the earbuds back immediately. Allow the case to air out completely, then gently clean the pins and slots for the earbuds with a dry cloth before reinserting them.

Stay Within The Bluetooth Range

One common issue with JBL earbuds not working on one side could be a Bluetooth range problem.

  • Bluetooth is a wireless technology with a limited range. Depending on the model and version, this range might extend from 50ft to 100ft.
  • To ensure a stable connection, keep your earbuds close to the audio source, such as your phone.
  • This can prevent pairing and connection issues that occur when they’re too far from each other.

Check Audio Balance On Your iPhone

Sometimes, the issue might be with the audio balance setting on your phone.

This feature allows users to shift sound between the left and right channels, giving the impression that one earbud is not working.

To adjust this on iPhones, go to Settings > Accessibility > Audio/Visual. Make sure the toggle for Mono Audio is disabled and the balance is centered.

Check Audio Balance On Android Devices

For Android devices, the process to check and adjust the audio balance is slightly different.

Navigate to Settings, then Accessibility and look for Hearing Enhancements or similar options. Here, you’ll find settings for Left/Right Sound Balance.

Max Volume Limiter

If the volume on your JBL earbuds seems unusually low, the Max Volume Limiter feature in the JBL Headphones app might be active.

This feature is designed to protect your hearing by limiting the volume to 85dB on both earbuds.

Sometimes, a firmware glitch might cause this setting to reduce the volume significantly. Disabling it can help.

Contact JBL Support

In cases where one earbud seems damaged or dead, perhaps due to battery failure, a loose wire inside, or issues with the PCB, it becomes a tricky business to fix. In such situations,

I recommend utilizing your warranty and contacting JBL support. Their agents can provide troubleshooting steps or might offer a replacement unit if your earbuds are within the warranty period.

Opening them up for repairs, especially for locating parts on platforms like eBay, should be a last resort.
