Często zadawane pytania

How does the AI Sound Boost actually improve the audio quality?
The 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.

Is the 34-hour battery life guaranteed even at high volumes?
Playtime 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.

Can I use the Boombox 4 as a power bank for my phone?
Yes, 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.

What is the advantage of the IP68 rating over older IPX7 models?
While 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.

Can I connect my older JBL speakers to the Boombox 4?
The Boombox 4 uses Auracast™ 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.
