Thanks for your feedback. We're always looking for ways to improve. With our JBL Reflect Aero, source devices (phones, tablets, etc.) all behave a bit differently. Some have very loud outputs, and some can be quite a bit lower, even at maximum volumes. You may try to use an equalizer on your music application to adjust the volume to your preference. If you need more help, please contact our customer support.

Thank you for your feedback. Our JBL Reflect Aero TWS comes with 3 sizes of sealing eartips and 3 sizes of Powerfins enhancers. 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 further assistance, please contact us.
