Compare Ultimate Ears Wonderboom 4 Speaker vs Bang & Olufsen Beosound A1 Speaker 3rd Gen

Review evidence says the A1 does not support AirPlay, so Apple users still rely on Bluetooth or wired USB-C rather than Wi-Fi/AirPlay streaming.

Multiple reviews cite the dual 30W Class D amplification or 60W total output, supporting unusually strong output for the compact chassis.

Most reviews report there is no companion app support for Wonderboom 4, limiting control to on-device buttons and preset modes. One YouTube review claims UE Boom app support and more features, making app expectations inconsistent across sources.

The B&O app is repeatedly described as helpful, responsive, and one of the best of its kind, though one reviewer could not get built-in radio working.

Audio format support centers on SBC, AAC, aptX Adaptive, and USB-C wired audio rather than Wi-Fi-based formats.

Backward pairing behavior is reported inconsistently: some sources state pairing with Wonderboom 3 is supported, while at least one review claims stereo pairing only works with another Wonderboom 4.

Backwards compatibility is a strength for stereo pairing because the third-generation speaker can pair with a second-generation A1.

Battery life is consistently strong for the size, with many reviews citing about 14 hours and some reporting it can meet or slightly exceed that under typical use. One long-use test reports closer to 12 to 13 hours at moderate volume.

Battery life is consistently positive, with most third-generation reviews citing 24 hours and several testers finding that figure believable or conservative.

Codec support is characterized as basic, with at least one detailed review stating it is SBC-only and lacking higher-bitrate options typical of more premium speakers.

Bluetooth codec support is strong for the class thanks to AAC and aptX Adaptive alongside basic SBC support.

Bluetooth stability is generally described as reliable and lag-free in several reviews, but one test reports audio cutouts on a Samsung phone, suggesting some device-dependent variability.

Connection stability is generally praised, with reviewers reporting no dropouts or solid pairing, though one garden-range test eventually cut out at distance.

Range is repeatedly described as excellent for the size, with mentions around 40m or roughly 131 feet and general praise for long-distance stability in open spaces.

Range evidence is moderate, with one review citing about 10 meters outdoors and another suggesting real-world limits near the end of a garden.

Construction is one of the most consistent strengths, with reviewers praising premium aluminum, polymer, finish quality, and overall craftsmanship.

Charge time is typically described as a few hours to full, with specific mentions around 2.5 to 2.6 hours. One review notes no fast charging and that topping up can take a while.

Charging time is functional but not fast; several reviews cite roughly three hours and describe it as long or leisurely.

The A1 is repeatedly described as cohesive, unified, controlled, and spacious rather than scattered or disjointed.

Physical button controls are repeatedly described as simple and easy to use, with a layout that reduces accidental presses and supports quick playback and volume adjustments.

Physical buttons are generally praised as responsive, tactile, clicky, and easier to use.

Design is consistently described as fun, rugged, and compact with distinctive oversized volume buttons and multiple color options, balancing durability with a playful look.

Design and aesthetics are a standout consensus strength, with reviewers repeatedly emphasizing the premium, stylish, minimalist look.

Detail and separation are frequently praised at moderate volumes, especially considering the size. At louder settings, multiple reviews note reduced detail and more aggressive DSP behavior.

Detail retrieval is strong across reviews, especially through the midrange, vocals, and small instrumental textures.

Several reviews report quality loss at high volume, including bass roll-off, harsher upper mids or treble, and general collapse in fidelity when pushed hard. Some reviewers found it stays fairly clean for its size, but the overall trend is a sweet-spot below maximum.

Distortion control is mostly strong at higher volumes, though one review notes distortion or strain on demanding bass-heavy tracks.

Drop durability is consistently positioned as strong, with multiple reviews referencing drop testing around 1.5m or 5 feet and an overall rugged build.

Durability is mixed: IP protection and prior-generation bump resistance help, but several reviewers warn the aluminum can scuff or may not survive rough drops like rugged JBL rivals.

Dust resistance is repeatedly cited as part of the IP67 rating, making it well suited for beaches, camping, and outdoor environments.

Dust resistance is strongly supported by repeated IP67 references and explicit dustproof or dust-resistant descriptions.

Dynamic performance is capable for the size but not class-leading; some reviews praise dynamism while others say rivals offer larger dynamic swings.

EQ control is mostly limited to preset modes such as Outdoor Boost and Podcast mode, and several reviewers found these modes of limited usefulness. A minority source claims full app-based EQ options, but the broader set of reviews does not support that experience.

EQ customization is a clear app strength, with preset modes and a visual sound control repeatedly described as useful and approachable.

Everyday usability is strong because reviewers find the speaker simple to operate, portable, and easy to live with in travel, desk, shower, and small-room use.

Float behavior is generally positive, but multiple sources mention practical caveats: audio may not play while floating, sound can change when wet, and it may tip over in the water so the sound does not project as expected.

Tuning is often described as balanced for the size, with punchy bass that does not overwhelm mids and highs at reasonable volumes. Several reviewers also note bass reduction or a thinner presentation when using outdoor-style EQ modes or pushing volume very high.

Frequency balance is generally warm, rich, and controlled rather than strictly neutral, with impressive bass for size and some caveats around bass depth or treble impact.

Google-related integration is specifically mentioned as Google Fast Pair support in at least one review, making initial setup faster on compatible Android devices.

Google-related support appears through Google Fast Pair, making Android pairing easier alongside Microsoft Swift Pair and Apple-focused support.

The integrated loop is useful for clipping or carrying, but multiple reviews criticize it as cheap or not very functional compared with a sturdier strap or carabiner-style solution.

The strap is usually praised as elegant or useful for carrying, though one review notes there is no carrying case and another notes leather may not suit every buyer.

Pairing a second speaker is commonly supported for louder playback or true stereo. However, reviewers disagree on cross-generation pairing and many note a lack of broader multi-speaker party modes compared with app-driven ecosystems.

Inter-speaker connectivity is strong because multiple reviews confirm stereo pairing, including pairing across second- and third-generation A1 units.

Maximum volume is widely described as impressive for the speaker size and capable of filling small to medium spaces. A recurring theme is that the best listening is below max volume, where quality holds together more reliably.

Maximum volume is good for the size and small spaces but not ideal for big outdoor parties or competing with larger JBL-style speakers.

Low-volume performance is positively noted in at least one review, highlighting that it can play quietly without losing usability, supporting flexible use in smaller indoor spaces.

Microphone support is well covered, with reviews describing built-in mics, mute controls, FarField technology, and speakerphone use.

No summary yet.

Multi-speaker pairing is a strength in the included reviews, especially because the app supports stereo setup and cross-generation pairing works.

Multipoint support is mentioned as available by some reviewers, enabling easy switching between two connected devices for shared DJ duties.

Multipoint connectivity is consistently supported, with multiple reviews describing two-device pairing and one YouTube reviewer calling it flawless.

360-degree, omnidirectional output is a defining feature and is repeatedly praised for being consistent around the speaker and useful for small group listening.

Omnidirectional sound is mixed: some reviews call it 360-degree or all-directional, while others say it is not truly 360-degree and depends on positioning.

On-device controls cover core needs such as power, pairing, play and pause, track skipping, mode switching, and often a battery check shortcut using the volume buttons.

On-device controls are well implemented, with power, pairing, volume, playback, and mic controls placed around the speaker body.

Price/value is the most repeated caveat: reviewers like the product but frequently call it expensive or weaker value than JBL alternatives.

Privacy evidence is limited but positive in one review because the removal of built-in Alexa means the speaker is not always listening for Amazon voice commands.

Setup is widely reported as quick and painless, with easy Bluetooth pairing and, in one case, near-instant connection aided by Google Fast Pair.

Setup is generally simple, helped by Fast Pair, Swift Pair, quick Bluetooth discovery, and straightforward operation.

Smart assistant integration is weak for the third generation because several reviews say Alexa has been dropped or is not built in.

Smart features are mixed: the app adds streaming, radio, EQ, and settings, but reviewers note no Auracast, no Wi-Fi, and no Alexa on the third-generation model.

Multiple sources confirm there is no built-in microphone, so it cannot be used for phone calls or speakerphone use.

Speakerphone quality is a useful strength, with several reviews saying calls are clear or successful and one caller rating it highly.

Status indication is generally handled via indicator lights for pairing and battery-related feedback, with at least one review calling out helpful battery-level visibility.

Status indicators are functional but mixed, with LEDs present for status and charging while one review wished the indicator were larger.

True stereo imaging depends on using two speakers in a paired configuration; multiple reviews say this makes a meaningful difference, with better scale and clearer production details than single-speaker playback.

Stereo imaging and separation are generally good for a compact Bluetooth speaker, with reviewers praising organized soundstage and instrument separation, though scale is limited.

Sustainability efforts are noted via recycled materials and more eco-oriented construction and packaging in at least two reviews, adding a modest environmental upside for buyers who care about materials sourcing.

Sustainability is a standout feature because reviews repeatedly cite Cradle to Cradle certification, modularity, repairability, and replaceable battery support.

USB-C charging is widely praised as a key quality-of-life improvement over prior generations and is consistently present across reviews.

USB-C charging is well supported and also doubles as a wired audio/data path in several reviews.

Value is generally seen as strong given the sound and ruggedness, but multiple reviews emphasize it is an iterative upgrade and that discounted Wonderboom 3 pricing can undercut Wonderboom 4 on pure value.

Value for money is mixed: some reviewers say the premium is justified by build and sound, while others say cheaper JBL or other rivals are better buys.

Voice assistant responsiveness is only supported in the older included A1 review, where Alexa setup is described as working equally well once configured.

Voice clarity is a recurring strength, with reviewers praising vocal intelligibility, natural vocals, and clear speech reproduction.

Water resistance is a major strength, repeatedly cited as IP67 and suitable for showers, poolside use, and accidental submersion within the rating limits.

Water resistance is strongly supported by repeated IP67 descriptions and sink, beach, pool, shower, and shallow-submersion references.

No summary yet.

Weight convenience is good but not perfect; reviewers find it easy to bag or carry, while noting it is not the lightest option at its size.

Wi-Fi streaming reliability scores low because reviews repeatedly say there is no Wi-Fi on board, so Wi-Fi streaming is not available to evaluate.

Multiple reviews explicitly note there is no wired AUX input, so listening is Bluetooth-only.

Wired input is a strength on the third-generation model because USB-C can handle wired audio as well as charging.
