In Short

  • The JBL Partybox 310 builds on the Partybox 300 and gains centimetres in all dimensions.
  • JBL designed a trolley-like cabinet with two huge wheels on the rear since a 17.5-kilogramme speaker is rarely lifted.
  • Even though 17.5 kg is hefty, this tiny PA is simple to transport.
  • The manufacturer promises an 18-hour battery life; however, at the highest SPLs, this is not true.
  • The cabinet looks like tiny Bluetooth speakers and is acceptable compared to competitors.
  • Due to IPX 4 splash water protection, the Partybox 310 may be used outside.

The JBL PartyBox 310 is a powerful Bluetooth speaker built for parties and events. With pulsing lights, booming bass and easy connectivity, it aims to liven up any gathering.

JBL PartyBox 310

The JBL PartyBox 310 has an imposing, almost industrial look. Its black cabinet measures 28 x 19 x 15 inches (WxHxD), larger than comparable speakers like the JBL Boombox 2.

Integrated grab handles and wheels make it easy to move. The wheels tuck away neatly when not in use. Large passive radiators on each side pulse along with the music. Multi-coloured LEDs surrounding the drivers put on an eye-catching light show. Build quality is excellent throughout. The PartyBox 310 feels built to last, with a thick, durable plastic exterior. Rubber bumpers offer protection during transport. Despite its size, the PartyBox 310 is manageable. The all-black colourway fits right in, whether you place it indoors or out.


The JBL PartyBox 310 comes packed with features to enhance the party atmosphere.

Light Show

LED rings surrounding the drivers offer dynamic, colourful lighting synced to your music. The lights react and change in time with bass, mids and treble. You can also customise the light show via the JBL PartyBox app. Options include:

  • Twenty-one pre-programmed modes like Pulse, Rainbow, Strobe, etc.
  • DJ lighting with complete RGB colour control
  • Light temperature adjustment from warm to cool
  • Manual color selection

It’s a vital lighting setup for a portable speaker. The pulsing lights liven up any party.

Sound Quality

The PartyBox 310 delivers 240 Watts of total power. Two 3.5-inch tweeters and two 6.5-inch woofers provide full-range sound. Dual bass radiators on the sides enhance the low end. There’s also There’ssignatJBL’s sunny bass, which is loud enough to keep the dancefloor moving. Overall, the sound is bold, powerful and surprisingly clear for a speaker this size. The PartyBox 310 can quickly fill a large room or outdoor space.


On the rear panel, you’ll find your/instrument input

  • Dual microphone inputs
  • Bluetooth input
  • Aux input
  • USB port for charging devices

The mic and guitar inputs make the PartyBox 310 ideal for karaoke or live music. You can quickly dial in the right mix using the integrated EQ knobs. Vocals sound full and rich, thanks to the dedicated mic channel. The PartyBox 310 provides crisp, detailed amplification – way better than most Bluetooth speakers.

Battery Life

The built-in battery lasts up to 18 hours at moderate volumes. Playing music loud will reduce battery life, but it’s enough for an all-day party or event. A full recharge takes about 2.5 hours. The PartyBox 310 also has an automatic standby mode. After 20 minutes of no audio input, it enters standby to save power.

Other Features

Other handy features include:

  • IPX4 splashproof protection
  • PartyBox app integration (more on this below)
  • TWS (stereo pairing)
  • Bass Boost button for exaggerated low-end

With Aux-in and Bluetooth, you can connect multiple devices and switch between them on the fly.

JBL PartyBox App

The JBL PartyBox app unlocks custom lighting, EQ, and more. It’s simple to connect: Pair your phone over Bluetooth.

From there, you can:

  • Customise the light show with colours and effects
  • Use DJ lighting control with virtual faders
  • Adjust the EQ or select presets like Concert, Club, etc.
  • Play audio and switch tracks from your phone
  • Set up TWS stereo pairing between PartyBox speakers
  • Update firmware

The app expands the capabilities of the PartyBox 310. The lights and sound can be easily adjusted to match your desired vibe.

Is The Bass Good

JBL PartyBox 310

With 240 Watts of power, the JBL PartyBox 310 delivers bold, room-filling sound perfect for parties. The tuning emphasises bass and highs for a lively sound. Kicking on the Bass Boost takes the low end to room-shaking levels. Mids are slightly recessed, but the overall tonal balance works excellently for pop, rock, hip-hop, and EDM. Vocals still cut through the mix nicely.

At moderate volumes, the PartyBox 310 provides impressive clarity. But crank it up full blast, and sound can get muddled, especially with dense tracks. Bass distortion creeps in at max volume.

Still, the PartyBox 310 delivers severe power and projection. It has no issues getting the party jumping at high speeds.

Ease of Use

Labeled buttons make navigating straightforward. Pairing devices over Bluetooth takes just seconds. The PartyBox 310 can store up to 8 device pairings in memory. Alternatively, plug into the Aux input for a wired connection. The rear EQ knobs provide quick adjustment for mic and guitar levels. Dialing in the right mix for an input takes no time at all. The PartyBox 310 couldn’t be set up and used for karaoke or live performances.
