Xtreme 4 Portable Bluetooth Speaker (Black) — IP67, 24 Hours Playtime + 6H Playtime Boost, Powerbank, Auracast, AI Sound Boost

Big, immersive Pro Sound from a tuned driver setup: two woofers, two powerful drivers and dual pumping Bass Radiators produce deep bass and detailed, room-filling audio. AI Sound Boost constantly analyzes the incoming signal in real time and uses an AI algorithm to predict loudspeaker movement and power response, pushing the drivers to their maximum capability to exploit the dynamic range. The result is louder, fuller sound with reduced distortion at high volumes and maximized bass output and overall loudness. Battery life lasts up to 24 hours, and tapping Playtime Boost can extend playback by up to 6 hours — Playtime Boost tunes and optimizes performance for louder, crisper sound when you need extra endurance. The built-in Powerbank function lets you charge phones and other devices on the go. Carrying is easy: the included shoulder strap adjusts for shoulder or crossbody wear so you can take music from room to room, to a backyard gathering or the beach. With an IP67 waterproof and dustproof rating the speaker can handle poolside parties, seaside picnics and other rugged environments. For larger setups, use Auracast multi-speaker connection to pair multiple units and scale the Pro Sound.
