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 Partybox Encore Essential ranks #8 of 76 boombox speakers by sound quality at $329.95.
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.
The case for the JBL Partybox Encore Essential: JBL Partybox Encore Essential uses 135mm woofer + 2x 44mm tweeters. The catch: Bass is limited by its 38Hz specification.
Buy the JBL Partybox 330 at $549.95 if you want a party speaker. Buy the JBL Partybox Encore Essential at $329.95 if you want a boombox speaker instead.
Battery life favors the JBL Partybox 330: rated for 18 hours against 6 hours for the JBL Partybox Encore Essential.

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.
