3. JBL App Reconnection Fix:

This suggested fix involving the JBL app aims to address potential connectivity or synchronization issues between the earbuds and the app, which could impact the functionality of the noise cancelling feature on the JBL Tune 230NC.

Here’s a breakdown of the steps and how they may help:

Opening the JBL App:

Initiates communication between the earbuds and the app, allowing for a real-time connection status check.

Placing Earbuds Back in the Case:

This action triggers a disconnection, essentially resetting the connection between the earbuds and the device.


When the earbuds are taken out of the case again, device usually connect JBL Tune 230NC TWS and the app. This re-establishment of the connection may resolve any glitches or communication issues that were hindering the noise cancelling activation.

4. Proximity Sensor Cleaning:

The proximity sensor in the JBL Tune 230NC, situated near the “L” and “R” engravings, plays a crucial role in detecting whether the earbuds are properly placed in the ears. 

If this sensor is obstructed or dirty, it may misinterpret the earbud’s placement, potentially causing JBL Tune 230NC noise cancelling not working issue.

Here’s how to address this:

Gently Cleaning the Proximity Sensor:

Use caution and a needle to clean the small black circle near the “L” and “R” markings on the earbuds. This ensures that the sensor is free from any dirt or obstruction.

JBL App’s “Check My Best Fit” Feature:

Open the JBL app and navigate to the “Check my best fit” feature. If the app displays an error message like “Please put both earbuds on,” it indicates that the proximity sensor is obstructed.

Cleaning the sensor allows it to accurately detect when the earbuds are in use, resolving potential misinterpretations that might have been preventing the noise cancelling feature from activating properly. 

This simple maintenance step ensures optimal functionality of the sensor, positively impacting the overall noise cancelling performance of the JBL Tune 230NC.

5. Charge The JBL Tune 230NC

Maintaining optimal battery levels is crucial for the effective functioning of features like noise cancellation in the JBL Tune 230NC. 

When the earbuds operate with low battery levels, they might lack the necessary power to execute power-intensive functions like noise cancellation. Hence you may face various problems including JBL Tune 230NC not charging.

Charging the earbuds not only replenishes the power but also optimizes overall performance, ensuring that noise cancellation operates at its best capacity. 

This approach addresses potential disruptions, stabilizes both software and hardware components, and plays a vital role in troubleshooting and resolving noise cancelling issues in the JBL Tune 230NC.
