These sit in different size classes, so this is not a straight ranking comparison. The Sony ULT Tower 5 ranks #5 of 53 party speakers by sound quality at $448; the Yeahbox Sonic Boom Ultra ranks #11 of 113 boombox speakers by sound quality at $388.
Why pick the Sony ULT Tower 5: A powerful party tower with deep bass, a removable long battery, and mic and XLR inputs for karaoke or DJ use. It links with other speakers (Auracast), which the Yeahbox Sonic Boom Ultra cannot. Watch for: It has a shorter 20-hour battery claim than the Sony ULT Tower 7’s 30 hours, no wheels, and only IPX4 splash resistance.
The Yeahbox Sonic Boom Ultra is the tougher option. A massively loud boombox with deep bass, long battery life, and HDMI ARC so it can double as a TV soundbar. It is rated IPX6 against IPX4 for the Sony ULT Tower 5. 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 Sony ULT Tower 5 ($448) for a party speaker; the Yeahbox Sonic Boom Ultra ($388) suits a boombox speaker instead.
