JBL PartyBox Stage 320 Portable Bluetooth Party Speaker - Black

The JBL PartyBox Stage 320 is a portable Bluetooth party speaker for terraces, living rooms and house parties. Two 6.5-inch woofers and two 1-inch tweeters deliver 240W RMS from 40 Hz to 20 kHz, and AI Sound Boost tunes the output in real time to keep distortion down at high volume. A lightshow with strobe and starry effects runs across the front grille.

The replaceable JBL Battery 400 gives up to 18 hours of play, and a 10-minute charge adds about 2 hours. At the back, two 6.35 mm jacks take a pair of wired microphones, or one microphone and a guitar, next to a 3.5 mm AUX input and a USB-A port for music from a USB drive and charging your phone. It connects over Bluetooth 5.4, and Auracast pairs two Stage 320s in stereo or links other Auracast-enabled JBL speakers. The JBL PartyBox app controls playback, EQ and the lightshow.

At 16.5 kg it rolls easily on two wide wheels, but lifting it into a car is heavy work. No microphone comes in the box, and there are no XLR inputs or USB-C port. It is IPX4 splash resistant, not waterproof. Owners praise its deep bass and lightshow, and reviewers note that the plastic body scratches easily.

Stand the speaker upright on a flat, stable surface. Charge it fully before first use: plug the supplied AC cord into the socket on the back, and a full charge takes about 3 hours with the speaker off. Press Power, then the Bluetooth button, and choose JBL PartyBox Stage 320 on your phone. Turn the microphone and guitar volume to minimum before you plug anything in, and set the slider next to the second jack to mic or guitar. Press the Auracast button on two speakers to link them. Install the JBL PartyBox app to control music, EQ and the lightshow, and to choose what the USB port does.
