**** The JBL Boombox 4 has clearly made a significant impression among customers, who celebrate its sound quality and robust build. Users praise the exceptional audio performance, highlighting a balanced and natural sound signature that deviates from the overpowering bass typical of many portable speakers. The inclusion of a detachable battery is viewed as a substantial upgrade, allowing for extended playtime of up to 34 hours, which caters perfectly to outdoor or party settings. However, despite the sound quality and impressive battery life, several customers express disappointment regarding the speaker's connectivity options. Unlike its predecessors, the Boombox 4 lacks a USB drive music playback feature and does not include an auxiliary input, which many deem essential for versatile use. Furthermore, the inability to connect older devices to the JBL Portable App adds to user frustration, especially for those with older smartphones. Another notable feature is the built-in power bank function, which allows users to charge other devices using the USB-C port, further enhancing its practicality for outdoor enthusiasts. Overall, the JBL Boombox 4 successfully combines excellent sound quality with user-friendly features, though its limited connectivity options could be a dealbreaker for some. **
