We've beefed up our bass and tweaked our tweeter. The outcome? Powerful, clearer bass even at max volume and crisp higher frequencies thanks to a clever new tweeter dome design, adding more depth to your speaker's sound. We also added our new proprietary tech, AI Sound Boost, which analyzes your music in real-time to deliver maximum acoustic performance with less distortion. It's like our own little audio genie in every Flip 7. So, now we can give you better all-around sound without the added pounds. Same size, bigger punch. Keep the mood alive for 14 hours on a single charge - and when we really need to squeeze some extra juice out of our jubilee, or another dance with our darling, we can get an extra 2 hours with Playtime Boost. Wouldn't it be great to share the vibes with our tribe? Now we can. With Auracast™, we can effortlessly stereo pair two Flip 7 speakers for a wider sound stage and connect multiple Auracast™ enabled JBL speakers to cover more ground with the same playlist.
