Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Xtreme 5 ranks #2 of 120 large speakers by sound quality at $399.95; the Yeahbox Sonic Boom Ultra ranks #11 of 113 boombox speakers by sound quality at $388.
The JBL Xtreme 5 is the lighter, tougher option. A large waterproof speaker with deep bass, wide, clean sound at volume and a removable 28 hour battery. At 6.4 lbs (2.9 kg) it weighs much less than the Yeahbox Sonic Boom Ultra at 24.3 lbs (11 kg). It is rated IP68 against IPX6 for the Yeahbox Sonic Boom Ultra. It links with other speakers (Auracast), which the Yeahbox Sonic Boom Ultra cannot. The tradeoff: High priced.
Why pick the Yeahbox Sonic Boom Ultra: A massively loud boombox with deep bass, long battery life, and HDMI ARC so it can double as a TV soundbar. It keeps a wired aux input, which the JBL Xtreme 5 lacks. The catch: The 500W peak-power rating doesn’t fully hold up: it gets noisy above roughly 80-90% volume, and the midrange isn’t fully refined, sometimes sitting a touch too forward.
Buy the JBL Xtreme 5 at $399.95 for a large speaker, or the Yeahbox Sonic Boom Ultra at $388 for a boombox speaker instead.
