True Wireless Stereo (TWS) headphones, like those in the JBL range, can sometimes experience issues with volume levels or audio balance. This is often due to a buildup of dust and earwax, which can affect one or both earbuds, leading to reduced volume or one earbud being louder than the other.
To prevent or resolve these common problems, periodic cleaning of the earbuds and ears is recommended. For general maintenance, remove dust and wax after each use. A pointed toothpick can help dislodge larger debris, followed by a cotton swab lightly dampened with rubbing alcohol for degreasing.
If volume or balance issues persist, carefully inspect the earbud and driver for any visible wax or dirt, particularly in the small grille openings that prevent sound output. A recommended troubleshooting step involves dipping the affected earbud tip into a solution of lukewarm tap water mixed with a small amount of mild dish soap. Ensure the earbud tip is submerged only up to a maximum depth of 1-2 mm. Submerging the earbuds deeper or for extended periods may void the warranty. Leave the earbud tip in the solution for approximately 2-3 minutes. Afterward, use a small brush, such as a toothbrush, to gently clean the grille. This process should effectively remove wax and dirt, restoring proper volume and balance.
