The JBL PartyBox 330 White is a portable party speaker with 280 W RMS output, a built-in battery and a telescopic handle with wide wheels for easy transport. Dual 165 mm woofers and twin 25 mm PEN dome tweeters deliver deep bass and clear highs indoors and outdoors. Two mic inputs plus a guitar input turn it into an instant karaoke or live-performance rig.

280 W RMS sound with AI Sound Boost for full bass outdoors

The JBL PartyBox 330 covers 40 Hz to 20 kHz, so bass stays full in a yard, on a terrace or at the beach. AI Sound Boost monitors the signal in real time and keeps the sound clean even at high volume.

Up to 18 hours of battery playtime and a 10-minute fast charge

A 68 Wh lithium-ion battery keeps the JBL PartyBox 330 playing for up to 18 hours, enough for a full party away from a power socket. A 10-minute charge adds roughly 2 hours, and the battery is replaceable if you want a spare.

Beat-synced lightshow with fast access from the top panel

Dynamic light trails and punchy strobe edge lights on the JBL PartyBox 330 sync to the music and turn any room into a dance floor. The redesigned top panel puts audio and light controls right under your fingers.

Karaoke and live sets with two mic inputs and a guitar input

Plug two mics and a guitar straight into the JBL PartyBox 330 for a karaoke duet or a small acoustic set. The speaker also works with JBL EasySing microphones.

Bluetooth 6.0 and Auracast for multi-speaker setups

Auracast links the JBL PartyBox 330 with other Auracast-enabled JBL speakers to double or triple your sound coverage. Sound, lights and settings are all controlled from the JBL One app.
