We appreciate your time in providing your feedback. To achieve the best seal and secure fit, you may try the three sizes of ear tips and powerfins enhancers that come with our JBL Reflect Aero TWS to know which best fits your ear. Next, 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, then gently twist the earbud to fit it securely into the shape of your ear. Alternatively, you can try other ear tips from third-party retailers that will fit your ear. If you need more help, please contact us. We're here to help.

Thanks for your feedback. We're always looking for ways to improve. For our JBL Reflect Aero, 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. We recommend cleaning the contact pins on the case and earbuds using a cotton swab with alcohol. These pins are sensitive to dust. Please ensure the pins are dried before placing them back on the case. This is for the mono mode, which lets you use both or just one earbud alone with full controls on their button commands. It will play in stereo mode if both earbuds are used and in mono mode if one earbud is inside the charging case. If you need more help, please contact our customer support.
