Choose the Wonderboom 4 if you want a compact, rugged speaker with strong 360-degree sound, USB-C and dependable battery life. Skip it if you need app EQ, a microphone, wired input or clean sound at maximum volume.
Best for
Best for listeners who want a small, tough Bluetooth speaker for travel, showers, parks, beaches, camping and casual rooms. It suits people who value simple controls, 360-degree sound, USB-C and dependable battery more than advanced app features.
Not for
Not for buyers who need custom app EQ, speakerphone calls, wired audio, Wi-Fi streaming or smart-speaker features. It is also a weaker fit for people who already own a Wonderboom 3 or need clean, powerful sound at party-scale volume.
Verdict
Across reviews, the Wonderboom 4 lands as a highly portable outdoor speaker built around simplicity: IP67 protection, flotation, USB-C charging, easy controls and broad 360-degree output. Reviewers repeatedly liked its punchy, balanced sound for the size and found battery life solid around the advertised 14 hours, with several noting it can handle rooms, decks, beaches and travel bags well. The tradeoff is that its feature set stays basic. There is little meaningful change from the Wonderboom 3, no real app support, no microphone or wired input, and EQ modes divide reviewers. Sound also loses refinement when pushed hard, so it is strongest as a small, durable everyday speaker rather than a party-scale or audiophile option.

Bang & Olufsen Beosound A1 V2
Older model: sound quality at a similar scaleT3 suggests the Bang & Olufsen Beosound A1 V2 for buyers with more budget wanting stronger sound.
Stereo performance is a clear plus when a second compatible Wonderboom is paired, with reviewers describing true stereo, left-right channels or louder two-speaker playback.
Everyday usability is strong thanks to simple operation, durable portability and suitability for travel, desktops, showers, parks and small gatherings.
Frequency response balance: 4.3, based on 10 reviews
Most reviews describe the tonal balance as strong for a compact speaker, with punchy bass, clear mids/highs and generally well-rounded 360-degree sound.
Cohesion is strong at normal volumes, with reviewers describing balanced sound, good separation, a clean presentation and a nicely balanced soundstage.
Battery life (if portable): 4.1, based on 11 reviews
Battery life is consistently solid around the advertised 14 hours, with one reviewer reporting about 12 to 13 hours at moderate volume and others calling it long-lasting.
Value is positive overall at around the budget-premium line, but several reviewers note the discounted Wonderboom 3 or cheaper rivals can reduce the Wonderboom 4’s appeal.
Value-for-money comments are mostly favorable, especially for sound and durability, but upgrade value is weaker when the Wonderboom 3 is heavily discounted.
Loudness / maximum volume: 4.0, based on 10 reviews
Reviewers generally found the Wonderboom 4 loud for its size, able to fill small to medium spaces, though one comparison-focused reviewer said it is not meant for genuinely loud large groups.
Voice reproduction is helped by vocal-forward tuning or Podcast Mode in several reviews, though SoundGuys found vocals harsh once the volume passed a certain point.
Multi-speaker pairing reliability: 3.6, based on 6 reviews
Multi-speaker pairing is useful but limited: reviewers liked two-speaker stereo, while also noting party-style linking or broader Ultimate Ears compatibility limits.
Backward or generation compatibility is mixed: some reviewers cite Wonderboom 3/4 pairing, while Tom’s Guide says stereo playback only works with another Wonderboom 4.
Distortion at high volume: 2.9, based on 7 reviews
High-volume behavior is the main sound weakness: several reviews heard harshness, strain or a quality drop near the top, while two YouTube reviews reported little distortion.
Wired input is absent, with reviewers explicitly saying there is no 3.5mm aux or physical wired option.
