A:Answer Thanks for your inquiry. For our JBL Tune Flex, you can try different sizes of eartips. 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. If you need more help, please contact our customer support.
