Ultimate Ears Wonderboom 4 Speaker Review
Bottom Line
Choose the Wonderboom 4 if you want a compact, rugged speaker with loud 360-degree sound, USB-C, and dependable battery life. Skip it if you need app EQ, wired input, call support, or bigger-speaker bass.
Best for
Best for people who want a small, durable Bluetooth speaker for travel, showers, pool days, picnics, dorm rooms, or casual outdoor listening. It suits buyers who prioritize 360-degree sound, simple controls, USB-C, and battery life over app-based tweaking.
Not for
Not for buyers who need app EQ, wired input, speakerphone calls, smart assistant features, hi-res codec support, or huge bass for large parties. Existing Wonderboom 3 owners may not find enough improvement unless USB-C is the deciding factor.
Verdict
The Wonderboom 4 lands as a rugged, easy portable speaker whose strongest evidence is consistent: reviewers like its loud 360-degree sound, compact build, IP67 durability, simple controls, USB-C charging, and solid battery life. The tradeoff is that Ultimate Ears changed little versus the Wonderboom 3, so discounted older units can look smarter for value. Sound quality is impressive for the size at normal volumes, but several reviewers heard harshness, bass loss, or strain when pushing it hard. It also lacks app EQ support, wired input, microphone calling, and advanced codec support, making it more of a dependable outdoor grab-and-go speaker than a feature-rich audio hub.

How does the Wonderboom 4 sound?
Reviewers generally found it loud, punchy, and balanced for its size, with strong 360-degree coverage. The main caveat is that sound quality can become harsh or lose bass at higher volumes.
