Short answer: the JBL Partybox 310. It ranks #4 out of 53 party speakers against the Soundboks Go’s #37, and it costs less, so there isn’t much of a real tradeoff. The JBL Partybox 310 has been replaced by the JBL Partybox 330. The Soundboks Go has been replaced by the Soundboks Mix. If you are buying new, get the JBL Partybox 330.
The Partybox 310’s pros describe the deepest bass of any battery-powered speaker and the most balanced sound in its class, backed by a measured 32Hz bass extension against 55Hz for the Soundboks Go. Its dual 6.5-inch woofers and tweeters put out 240W total against the Soundboks Go’s 2x72W from a single 10-inch woofer and tweeter. The Partybox 310’s only real downside is its size.
The Soundboks Go’s real strength is runtime, not sound. Its pros call out exceptional 40-hour battery life at mid-volume against just 18 hours for the Partybox 310, plus a swappable battery design with a second battery sold separately. Its cons note it isn’t as loud as other Soundboks models, and the spec sheet backs up the tradeoff: no app, no EQ, and no water resistance at all against the Partybox 310’s IPX4 rating.
Buy the JBL Partybox 310 for deeper bass, a more balanced sound, and a lower price, and consider it used since both of these speakers are discontinued.
Buy the Soundboks Go only if all-day battery life and a swappable battery pack matter more to you than sound quality or price.
