Move between listening and live performance with the JBL PartyBox 310. JBL Pro Sound, battery operation, wheels and a synchronised light show combine with microphone and instrument connectivity for a versatile party setup.

Key Features

  • 240W RMS of JBL Pro Sound – two 6.5-inch woofers and two 2.5-inch tweeters fill large spaces with full, energetic sound.
  • Dynamic light show – lights synced to the beat set the mood for dancing.
  • Built-in Karaoke mode – turn any playlist into a sing-along session.
  • Up to 18 hours of battery – a 72Wh lithium-ion battery keeps it running all night, or plug it into any outlet.
  • Smooth-glide wheels – move a 38-pound speaker without carrying it.
  • USB playback and charging – play MP3, WMA and WAV files from a USB drive, and top up a phone from the 5V/2.1A output.

Good to Know

Playtime is measured with the light show off and moderate volume, so expect less when you run lights and turn it up. The splashproof design handles a spill, but keep the speaker out of standing water.
