Thank you for your feedback. Our JBL Endurance Race 2 earbuds come with three sizes of eartips and one enhancer to help you achieve a comfortable fit. Please select the size that best suits you. To achieve the best seal and secure fit, you must create a tight seal within your ear canal. To do this, angle the ear tip slightly downward to make it easier to insert into your ear canal, gently twist the earbud to fit it securely into the shape of your ear, and continue twisting the earbud into your ear canal.

Thanks for your feedback. We're always looking for ways to improve. For our JBL Endurance Race 2 TWS, typically, the two earpieces should connect without any problems. However, wireless interference can sometimes disrupt their connection. To manually pair the earpieces and see if this resolves the issue, begin by forgetting or unpairing the headphones on your device. Then, manually pair the earpieces by placing both earbuds inside the charging case. Pair the headphones with your device again to check if this solves the problem. If not, proceed to reset the earpieces and then manually re-pair them. A reset can often resolve issues, similar to how restarting a computer or phone can solve many problems. Please note that resetting will erase all previous settings and pairings, so you will need to pair your unit with your devices again. To reset, remove both earbuds from the charging case, tap each earbud twice, then tap and hold for 5 seconds. After resetting, manually pair the earpieces together again by following the initial steps because the reset process does not automatically pair them; it only clears previous settings and resets the internal processor. Finally, pair the earbuds with your source device. If the issue still persists, please contact our customer support.
