These are not really the same size class, and that is the honest framing here. The JBL Partybox Stage 320 ranks #3 of 39 party speakers by sound quality at $499.95; the JBL Partybox 520 ranks #7 of 12 large party speakers by sound quality at $799.95.

Short answer: there’s no rating gap here, both sit at 4.6. Worth noting on the JBL Partybox Stage 320: Handle and wheels are convenient. The JBL Partybox 520’s case starts with 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.
Where they differ on paper:
- Battery Life: 18 hours (Manufacturer specified) vs 15 hours (Manufacturer specified)
- Drivers: 2x 6.5” woofers, 2x 25mm tweeters vs 2x 7.5” woofer, 2x 1” dome tweeter
- Amplifier Power: 240W vs 400W
- Stereo: Partially vs Yes
Choose the JBL Partybox Stage 320: Handle and wheels are convenient. Watch for: slightly sibilant in the treble at full blast. Price also favors it, $499.95 versus $799.95.
Consider the JBL Partybox 520 for JBL’s biggest battery-powered PartyBox combines very high output: Watch for: 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. You pay more for it as well, $799.95 against $499.95.
Buy the JBL Partybox Stage 320 at $499.95 for a party speaker, or the JBL Partybox 520 at $799.95 for a large party speaker instead.

JBL Partybox 520: $799.95 Amazon B&H Photo Video eBay
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.
