    Cz\u0119sto zadawane pytania<\/b><\/h4>\n

    How does the AI Sound Boost actually improve the audio quality?<\/b>
    \nThe AI Sound Boost uses a sophisticated algorithm to predict speaker movement and power response in real-time. This allows the speaker to push its drivers to their absolute limit safely, resulting in a much wider dynamic range and more powerful bass than standard portable speakers.<\/p>\n

    Is the 34-hour battery life guaranteed even at high volumes?<\/b>
    \nPlaytime depends on volume levels and music content. The \"28+6\" hour estimate is based on moderate volume levels. Using the Playtime Boost feature optimizes the performance to stretch the battery life when you need those extra few hours of music.<\/p>\n

    Can I use the Boombox 4 as a power bank for my phone?<\/b>
    \nYes, like previous premium JBL models, the Boombox 4 features a power-out port, allowing you to charge your smartphones or tablets directly from the speaker's massive internal battery so you never lose your music source.<\/p>\n

    What is the advantage of the IP68 rating over older IPX7 models?<\/b>
    \nWhile IPX7 only protected against water, the IP68 rating means the Boombox 4 is also completely \"dust-tight.\" This makes it much more durable for use in sandy environments (like beaches) or dusty outdoor trails without risking internal damage.<\/p>\n

    Can I connect my older JBL speakers to the Boombox 4?<\/b>
    \nThe Boombox 4 uses Auracast\u2122 technology for the most stable multi-speaker connection. While it works seamlessly with other Auracast-enabled devices, you can also use the JBL Portable app to check compatibility and link with various speakers in the JBL ecosystem.<\/p>\n\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
