Thanks for your feedback. Our JBL Vibe Beam has the “Check My Best Fit” feature in the JBL Headphones App, which helps ensure you’re using the correct ear tip size and proper placement for optimal sound. One of the common reasons for low volume is dust/dirt/debris blocking the ear tip screen. We recommend cleaning it using an alcohol-cotton swab of alcohol. If cleaning doesn't solve the problem, the next thing to check is the balance control. Check the balance control on your source device by going to the "Accessibility" settings, music player app, commonly found in the playback or EQ settings, and on the JBL Headphones App. Also, 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. We need to determine if the problem is in the device or the headphones. Try to connect the headphones to a different device (phone/tablet/music player) to see if it fixes the problem. If you need more help, please contact our customer support.

We appreciate your feedback. We understand that you're having trouble finding the left earbud and the charging case. We want to let you know that the JBL Headphones app can help locate the left earbud, as long as it has enough battery charge. However, please note that the app does not have a feature to locate the charging case itself. For further assistance, please contact us.
