JBL Endurance Race True Wireless Headphones

Thank you for bringing this to our attention. To get the best possible sound from our JBL Endurance Race, the most important step is achieving a secure, airtight seal by angling the earbud downward and gently twisting it into place. We recommend experimenting with all the provided ear tip sizes to find your perfect fit, as a proper seal instantly improves bass and clarity. If you’ve found that perfect fit but still notice a volume difference, the issue is typically caused by minor debris on the ear tip screen or a balance setting that needs to be centered in your app's accessibility menu. Taking a moment to clean the tips usually resolves this quickly and gets your audio back to a balanced, high-quality level.

Thank you for sharing your feedback on our JBL Endurance Race TWS. To get the best possible sound, create a tight seal by inserting the eartip at a slight downward angle, gently twisting the earbud to match the shape of your ear, and continuing to twist until it feels secure. Try this with each of the included eartip sizes to find the best fit. After a few attempts, the process becomes quick and easy each time you put them on.
