Short answer: the Soundboks Go for battery life, the JBL Partybox 330 for output. The Go runs an exceptional 40 hours at mid-volume and 10 hours at full volume, with a swappable design and a second battery available, but it is not as loud as the other Soundboks models. The 330 has a convenient handle and wheels, though its sound is nearly identical to the 310 and Stage 320 despite the power bump.

The case for the Soundboks Go: Exceptional 40-hour battery life at mid-volume (10 hours at full volume), swappable design (second battery $200 available). The catch: Not as loud as the other Soundboks.
Buy the JBL Partybox 330. It is rated higher for sound quality than the Soundboks Go and costs less, so there is no real case for the other one.

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.
