Reviewer verdict

Across 14 YouTube reviews, the Ultimate Ears Boom 4 earns a Summa score of 4.2/5, ranking #18 among Bluetooth Speakers. Reviewers most often praise its sound quality, features, connectivity, while the most common criticisms concern features, value.

The Boom 4 is widely praised for its strong 360° sound and punchy bass, with reviewers frequently noting clearer highs and room-filling volume (35 mentions under sound quality). Reviewers also highlight useful features and software support—things like podcast mode, outdoor boost, a Magic Button, and app-based EQ—mentioned repeatedly across reviews (25 mentions for features). Connectivity and multi-speaker pairing are commonly applauded, including long Bluetooth range, PartyUp/stereo linking and NFC or Google Fast Pair conveniences (22 mentions). Critics also regularly compliment the rugged, waterproof build and portable mid-size design, noting IP ratings, floatability, and easy-to-carry straps (21 durability mentions, 13 portability mentions).

Most criticisms focus on missing or dated features: several reviewers point out older charging standards (micro USB on some models), lack of aux/Wi‑Fi or microphone, and limited app support for certain models (14 mentions under features). Value concerns arise too, with some reviewers calling specific models overpriced or not enough of an upgrade over predecessors (7 mentions). Connectivity limitations and pairing fragmentation are also reported, such as restricted multi-speaker pairing between certain UE lines (3 mentions). A smaller set of reviewers mention minor drawbacks like less bass compared with larger speakers, charging speed and battery differences, and design or durability caveats in specific conditions (additional scattered mentions across categories).
