These are not really the same size class, and that is the honest framing here. The JBL Partybox 330 ranks #2 of 40 party speakers by sound quality at $549.95; the JBL Boombox 3 Wifi ranks #23 of 76 boombox speakers by sound quality at $389.95.
Why pick the JBL Partybox 330: A highly complete rolling party speaker: removable battery, telescoping handle and wheels, light show, Auracast, USB-C lossless and optical inputs, plus dual mic/guitar inputs. Watch for: It remains very large and heavy, and the sound improvement over the JBL Partybox Stage 320 is modest rather than transformational.
Why pick the JBL Boombox 3 Wifi: Loudest speaker in the category. The catch: Bass boosted.
Buy the JBL Partybox 330 at $549.95 for a party speaker, or the JBL Boombox 3 Wifi at $389.95 for a boombox speaker instead.
Water resistance is not close: the JBL Boombox 3 Wifi is rated at IP67 (brief submersion), well ahead of the JBL Partybox 330 at IPX4 (splashing).

The Two Speakers In Full
JBL Partybox 330: $549.95 Amazon B&H Photo Video eBay
Pros: A highly complete rolling party speaker: removable battery, telescoping handle and wheels, light show, Auracast, USB-C lossless and optical inputs, plus dual mic/guitar inputs. It supplies a little more power than the JBL Partybox 310 and JBL Partybox Stage 320, while reviewers report better midrange clarity than the older JBL Partybox 310 and the same deep party-speaker bass.
Cons: It remains very large and heavy, and the sound improvement over the JBL Partybox Stage 320 is modest rather than transformational. JBL removed the dedicated mic gain/control knobs found on earlier models, a real drawback for frequent karaoke use. Do not upgrade from a JBL Partybox 310 or JBL Partybox Stage 320 just for the higher watt figure.
