#2 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 310 and Stage 320, while reviewers report better midrange clarity than the older 310 and the same deep party-speaker bass.

Cons: It remains very large and heavy, and the sound improvement over the 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 310 or Stage 320 just for the higher watt figure.

How it compares: Just above it: Sony ULT Tower 7 - $100 more, 12 more hours of battery life. Just below it: JBL Partybox Stage 320 - $50 cheaper.
