A Delhi party does not end when the power does. Eighteen hours of playback on a full charge means a sangeet that starts at four in the afternoon and runs past midnight never needs a wall socket — and when the colony load-sheds mid-song, the music simply keeps going. If the evening runs longer still, ten minutes on charge buys another two hours, and the battery itself is replaceable, so a second pack carries you straight through a full event without a pause in the playlist.
AI Sound Boost — louder and cleaner, right at the top of the dial
Most speakers sound their worst exactly where you use them most: at full volume. JBL's AI Sound Boost reads the content and the surroundings in real time and optimises the output accordingly — pushing volume and clarity up without letting distortion creep in, and lifting bass response so the low end stays full instead of thinning out. On a terrace where the sound has nowhere to reflect, or in a packed drawing room where bodies soak up the mid-range, that adaptive tuning is the difference between loud and genuinely good. Across 240W RMS of JBL Pro Sound, driven by dual 6.5" woofers for deep bass and dual 25mm dome tweeters for crisp highs, the PartyBox 320 is engineered to fill large indoor and outdoor spaces with concert-like sound.
Telescopic handle, large wheels, splash-resistant — built to be moved
At 16.5 kg this is a serious piece of audio equipment, and JBL has engineered it to travel like luggage rather than furniture. The integrated telescopic handle and large wheels let one person roll it from the car to the lift to the terrace without help — which matters in a city of third-floor flats and narrow staircases. The chassis is strong and impact-resistant for rugged repeated use, and the build is splash-resistant, so an unexpected monsoon shower on the terrace or a drink knocked over on the dance floor is an inconvenience, not an emergency.

🎉 Built for how India actually parties
The karaoke tuning with EQ presets is the one families come back for — antakshari, a birthday, a wedding function at home, and the vocals sit cleanly on top of the track instead of fighting it, with the light effects adding to whoever is holding the mic.
Two 6.5" woofers handle the bass and two 25mm dome tweeters handle the highs, so a big open terrace or a full hall gets depth and detail at the same time instead of just volume.
The rechargeable lithium-polymer pack comes pre-installed and can be swapped for an optional extra battery, so a long event carries on without stopping to find a socket.
Two mics, or a mic plus a guitar, plug straight in with professional-grade EQ presets and built-in light effects — a home function becomes a stage without any extra gear.
EQ, volume, light effects and source selection all run from your phone, so you can adjust the mix from across the room without pushing through the crowd.
