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.

Thanks for your inquiry. We're here to help with your JBL Reflect Aero TWS. 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. If your right earbud doesn't have sound, check the balance control on your source device by going to the "Accessibility" settings and on your music player app, commonly found in the playback or EQ settings. If the issue persists, please contact our customer support.

Thank you for taking the time to provide us with your feedback. We are sorry to hear that the fit of our JBL Reflect Aero didn't meet your expectations. These earbuds come with a choice of 3 sizes of ear tips and Powerfins enhancers (S, M, or L). You may choose the right size for your ears so that they will stay in your ears and not fall out. If you need more help with your device, please contact our customer support for further assistance.

Thank you for bringing this to our attention. 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 or you may use the Check My Best Fit feature test on the JBL Headphones app to find your own unique fit. Also, feel free to tell us more about your other concerns and contact our customer support so we can assist you further. https://support.jbl.com/us/en

Thank you for bringing this into our attention. That’s not the experience we want you to have with our JBL Reflect Aero. With TWS ear buds charging issues, it's frequently caused by foreign matter on the metal charging contacts. This can include sweat, grease, ear wax, etc. Please clean the contact points of your earbuds and the charging case using a cotton swab and alcohol. If issue persist, your unit comes with a 1-year manufacturer's warranty, please reach out to our customer support for further assistance.
