Short answer: the JBL Partybox 330. It ranks #2 of 39 party speakers against #3 for the Electro-Voice Everse 8, and it costs $249.05 less on top of that. This is not a close call.
The Everse 8’s whole design philosophy is efficiency over stereo width. Its high-efficiency 8-inch woofer and 1-inch tweeter reach 2-3x the volume of typical speakers at the same wattage, and our notes credit it with good midrange and treble. But it’s not stereo at all, and it’s designed for more loudness than deeper bass, a real tradeoff against a speaker built around two woofers and two tweeters.
The Partybox 330 has one honest limitation: it’s not much of an upgrade over JBL’s own cheaper models. Our notes say its sound quality is nearly identical to the 310 and Stage 320 despite the power bump to 280W, so it’s not worth buying new if you already own either of those. What it does add over them is a handle and wheels for portability, a customizable lightshow, an optical TV input, USB-C lossless playback, and dual microphone and guitar inputs for karaoke or live sets.
A few practical differences stand out: the Everse 8 includes an XLR input for professional gear that the Partybox 330 lacks, while the Partybox 330 runs longer on battery (18 hours against 12) and is far heavier at nearly 38 lbs against the Everse 8’s 17.6 lbs.
Buy the JBL Partybox 330 for better all-around sound quality, a lower price, and more inputs, unless you specifically need XLR connectivity.
Buy the Electro-Voice Everse 8 if you need genuinely extreme output per watt from a battery-powered speaker, such as for outdoor PA use, and can accept mono sound.

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.
