We appreciate your feedback. Our JBL Endurance Race comes with S/M/L ear tips. We would suggest trying out the different sizes of ear tips to have the desired fit. You can try the "Check My Best Fit" banner in JBL Headphones App to walk you through getting the best fit and will let you know when you've accomplished it. Regarding the connectivity issue, Bluetooth works best in open spaces. Walls, other devices, or distance can affect the connection. Try unpairing and re-pairing your earbuds. If the issue persists, connect them to another device. If that doesn't work, do a factory reset. With both earbuds on, and not charging, tap two times and hold the button on the third tap for more than 5 seconds. You may need to 'forget' the headphones in Bluetooth settings on your phone/tablet in order to pair them again. If you need further assistance, please contact us.

Thanks for your feedback. Resetting your JBL Endurance Race TWS may fix the issue, much in the way rebooting a computer or phone fixes many problems. To reset, with both earbuds on, and not charging, tap two times and hold the button on the third tap for more than 5 seconds. You may need to 'forget' the headphones in Bluetooth settings on your phone/tablet to pair them again.

Note: RESET will wipe all previous settings and pairings, so it will be necessary to pair your unit with your devices again.
