JBL Partybox 520 vs Partybox 720

Last updated: September 21, 2026

Short answer: the 720 if the extra size and cost are trivial to you, the 520 if they aren’t. These rank #5 and #7 out of 12 large-party speakers, at $1099.95 and $799.95, the two biggest battery-powered speakers JBL currently makes.

JBL Partybox 520 vs JBL Partybox 720

The 720 is described in our own notes as the biggest, best-sounding battery-powered JBL, which is a real distinction from the 520’s “biggest battery-powered JBL” framing: size alone isn’t the differentiator, sound quality is. That’s what the two ranking places and $300 are buying.

Both share the same real weaknesses. Neither speaker’s Auracast pairing works with non-JBL gear, and both are described as somewhat dark by default. The 720’s notes specifically flag needing a treble boost to sound neutral, and the 520 likely benefits from the same correction given the shared platform.

The physical difference is real and worth planning around. The 720 is 31 kg (68.3 lbs) against the 520’s 25.5 kg (56.2 lbs), a 5.5 kg (12.1 lbs) gap that matters if you’re loading this in and out of a car regularly rather than leaving it stationary. Battery life is identical at 15 hours on both.

Buy the 520 if you want JBL’s largeparty flagship experience without the heaviest option, and $300 back. Buy the 720 if the sound quality gap is worth the extra size and cost to you. Both are stationary party equipment either way, so the weight difference matters most during setup and transport, not use.

Still deciding? The full Portable Bluetooth rankings cover every ranked option.

JBL Partybox 520 ranking card

Pros: JBL’s biggest battery-powered PartyBox combines very high output, deep chesty bass, wheels and a telescoping handle with a capable app EQ, lights, USB-C audio and mic/instrument inputs. RTINGS finds it loud enough for backyards and unusually well-equipped for a battery party speaker.

Cons: It is very large and heavy, Bluetooth latency is high for video, and its front-facing design loses much of the mids and treble to people off to the sides. The bass-heavy default can also make dialogue less clear without EQ.

JBL Partybox 720: $1,099.95 Amazon B&H Photo Video eBay

JBL Partybox 720 ranking card

Pros: JBL’s most powerful battery-equipped PartyBox combines 800W output, two removable batteries, wheels, a light show, Auracast, USB-C playback, app EQ and karaoke/guitar inputs. Independent testing confirms very high output, strong bass and a flexible 5- or 7-band EQ; it can easily cover a backyard or large event.

Cons: At 31kg and 94cm tall, it is still cumbersome despite the wheels. Its front-facing vertical driver layout gives uneven sound to listeners at the sides or behind it, bass compresses at very high volume and reviewers note a faint hiss. The default is dark/bass-heavy, so use the app EQ and do not expect a neutral indoor hi-fi speaker.
