JBL PartyBox Stage 320 – Portable Party Speaker with Light Show and Wheels

The JBL PartyBox Stage 320 is a portable party speaker that combines 240W RMS of JBL Pro Sound with AI Sound Boost, a futuristic light show and up to 18 hours of battery playtime. A telescopic handle and wide, sturdy wheels make it easy to roll from the living room to the garden, beach or rooftop. It's a good fit for house parties, karaoke nights, family gatherings and outdoor events.

Powerful JBL Pro Sound

Two 6.5" woofers deliver clean, precise, deep bass, while two 1" dome tweeters keep vocals and highs clear. Output power is 240W RMS (IEC60268), and frequency response is 40 Hz to 20 kHz (-6dB), with a signal-to-noise ratio above 80 dB.

AI Sound Boost

AI Sound Boost analyzes the incoming audio signal and predicts how the drivers will move. It uses this to maximize output while keeping distortion low, for powerful, clean sound at high volume.

Up to 18 Hours of Playtime with a Replaceable Battery

The Stage 320 runs on a JBL Battery 400 (Li-ion, 68 Wh) for up to 18 hours of playtime, depending on volume level and audio content. A 10-minute fast charge adds up to 2 hours of play, and a full charge takes about 3 hours with the speaker off. Because the battery is replaceable, you can swap in a charged spare (sold separately) and keep the party going. You can also plug the speaker into AC power (100–240V).

Futuristic Light Show

Starry lights, cool light trails and strobe effects all sync to your music, turning any space into a party. You can customize the light show from the top panel or in the JBL PartyBox app.

Auracast Multi-Speaker Connection

With Auracast, you can stereo-pair two speakers for a wider soundstage, or connect multiple Auracast-enabled JBL PartyBox speakers for bigger sound across a larger space.

Bluetooth 5.4 and JBL PartyBox App

Stream music wirelessly over Bluetooth 5.4. The JBL PartyBox app lets you add interactive party effects, control your music and adjust EQ settings from your phone.

Splashproof Design

With an IPX4 rating, the Stage 320 is protected against splashing water from any direction, so you can use it with more confidence at pool parties and outdoor events. It is splashproof, not waterproof, and should not be submerged.

Telescopic Handle and Wide, Sturdy Wheels

Measuring 335 × 669 × 385 mm and weighing 16.5 kg, the Stage 320 is easy to move thanks to its telescopic handle and wide, sturdy wheels.
