JBL Boombox 4 vs JBL Partybox Stage 320

Last updated: September 19, 2026

Short answer: these solve different problems at the same price. The Boombox 4 ranks #19 of 39 boombox speakers, the Partybox Stage 320 ranks #3 of 39 party speakers, and both currently cost $549.95. The real decision is portability versus party features, not sound quality.

JBL Boombox 4 vs JBL Partybox Stage 320

The Boombox 4 is built to be carried, the Stage 320 is built to be wheeled. At 13.2 lbs against 36.4 lbs, the weight gap alone rules out cross-shopping for most buyers. The Boombox 4 also carries an IP68 rating for full submersion, while the Stage 320 is only IPX4 splash-resistant, and the Boombox 4’s 28-hour battery beats the Stage 320’s 18 hours. If you need something you can throw in a backpack or a boat, the Stage 320 is not built for that.

The Stage 320 is built for hosting, not hauling. It adds a handle and wheels for moving it around a venue, a microphone input with karaoke echo, a guitar input, and customizable lighting, none of which the Boombox 4 offers. Our notes flag the Stage 320 as slightly sibilant in the treble at full blast, but it also keeps more bass than the older 310 at high volume.

The Boombox 4 has its own tradeoffs. Reviewers note it is pretty overpriced for the category and, out of the box, sounds worse than the Boombox 3 it replaced; the 7-band EQ helps close that gap if you’re willing to tune it yourself. It also drops the aux input that older boomboxes had, relying on Bluetooth or USB-C instead.

Buy the JBL Boombox 4 if you want a true portable speaker with full waterproofing and the longer battery life, and you’re not planning to host with it.

Buy the JBL Partybox Stage 320 if you want karaoke and guitar inputs, wheels for moving it around, and don’t mind that it’s not meant to leave the yard.

Pros: Pretty insane output capability for the size. Measured bass extension of 41Hz (-10dB).

Cons: Pretty overpriced for the category. Better than the Boombox 3 mostly because there are more 7 EQ bands instead of just 3 and it can be better tuned. Try Oluv’s EQ for it. Out of the box sounds worse than the Boombox 3. No Aux input.
