JBL Partybox 330 vs Audiocase S5

Last updated: August 20, 2026

Short answer: the JBL Partybox 330. It ranks #1 of 50 party speakers by sound quality at $629.95; the Audiocase S5 ranks #26 and costs $645, so there is not much of a tradeoff to weigh.

On the JBL Partybox 330 side: Handle and wheels are convenient. Watch for: Sound quality is nearly identical to the 310 and Stage 320 despite the power bump, so probably not worth an upgrade if you already own either of those.

What the Audiocase S5 gets right: Removable battery. The tradeoff: Not stereo. Boosted upper bass, not as much clarity as higher ranked speakers.

One note: the Audiocase S5 is discontinued, but it still ranks #26 of 50 party speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.

Buy the JBL Partybox 330. It ranks higher for sound quality than the Audiocase S5 and costs less, so there is no real case for the other one.

If battery life is a priority, the Audiocase S5 is rated for 30 hours versus 18 hours for the JBL Partybox 330.

If water resistance matters to you, the JBL Partybox 330 at IPX4 (splashing) holds up far better than the Audiocase S5 at no water resistance.

JBL Partybox 330: $629.95 Amazon Bhphotovideo

JBL Partybox 330 ranking card

Pros: Handle and wheels are convenient. Customizable lightshow. Removable battery. Slightly more power than the 310 and Stage 320 (280W vs 240W). Adds an optical TV input and USB-C lossless playback, plus dual mic and guitar inputs for karaoke and live sets.

Cons: Sound quality is nearly identical to the 310 and Stage 320 despite the power bump, so probably not worth an upgrade if you already own either of those. Removed the dedicated mic gain and microphone control knobs found on the 310/320. Some people don’t like the new lightshow design. Very large. Note, JBL daisychain is not compatible with any other non-JBL speaker and is possibly a fully digital signal.
