JBL Partybox 330 Portable Battery-powered Party Speaker

The JBL PartyBox 330 shows up loud and clear. Unreal sound quality meets a wider soundstage and AI Sound Boost to power bold bass and crystal-clear highs—all while a beat-synced lightshow boosts the vibe. With up to 18 hours of playtime, splash-proof design, telescopic handle, and all-road wheels, this speaker moves with the party wherever it goes. A 10-minute charge adds another 2 hours, or swap in a spare battery (sold separately). Want even bigger sound? Auracast™ lets you pair with other Auracast-enabled JBL speakers to double or triple the sound power. And you can control it all from anywhere with the JBL One App.
