JBL Boombox 4

This speaker elevates the listening experience by delivering massive JBL Pro Sound with the deepest bass, now featuring AI Sound Boost technology which analyzes music in real-time to maximize power with less distortion. It offers up to 34 hours of playtime (28 hours plus an extra 6 hours with Playtime Boost) and an IP68 waterproof and dustproof design, making it ready for any adventure. For a wider sound stage, you can connect multiple speakers using the new Auracast™ feature.
