Superior JBL Pro Sound: We?re cranking out 800 watts of JBL Pro Sound?loud, clean, and full of deep bass from those two massive 9? woofers. The tweeters keep the highs crisp and clear, so every track hits just right and the dance floor stays packed. Futuristic lightshow: Mix all that epic sound with a lightshow to match?vibrant stars, flowing trails, and strobes that move with the beat. It?s a full-on vibe. Up to 15 hours playtime: Keep the music going for up to 15 hours on a single charge. Need more juice? Swap in the backup batteries (sold separately) and keep it moving. Just need a quick boost? A 10-minute fast charge gets you up to 2 extra hours of playtime. Ergonomic integrated handle and wider sturdy wheels: Taking the party outside just got easier?wider wheels roll smooth on rough ground, and the built-in handle makes it easy to grab and go. IPX4 Splash proof: Whether we?re hanging in the park or chilling by the pool, the PartyBox 720 is IPX4 splash proof?so a little water is no big deal. Multi-speaker connection by Auracast: When the crew gets bigger, the sound does too. We can pair two PartyBox 720s for true stereo vibes or link up more JBL Auracast- enabled speakers wirelessly?so the music grows with the moment. Control your party, right from the JBL PartyBox app: Don?t babysit the speaker?just use the JBL PartyBox app to control the music, EQ, and lightshow from wherever: the bar, the dance floor, or beyond.
