The Bang & Olufsen app is widely praised as polished, stable and genuinely useful, with EQ, stereo setup, battery readouts and extra content. One review noted a radio feature hiccup.
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.
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.
Battery life is one of its best features. The 24-hour claim is repeatedly praised and several reviewers found real-world endurance strong or even conservative at moderate volume.
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.
AAC and aptX Adaptive support are appreciated, but Bluetooth 5.1 feels dated and the lack of Auracast comes up repeatedly as a missed opportunity.
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 stability is a strong point, with reviewers reporting dependable pairing and no meaningful dropouts in normal use.
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.
Bluetooth range is solid for normal portable use, roughly room-to-garden or around 10 meters, but nobody describes it as exceptional.
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.
Charging takes around three hours, which is acceptable but commonly described as leisurely or on the long side.
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.
Its presentation is repeatedly described as composed, unified and together-sounding, with strong musical organization.
Physical buttons are consistently described as clicky, positive and easy to use.
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.
Design is the headline feature. Nearly every review describes the A1 3rd Gen as beautiful, premium, luxurious and unusually desirable for a portable speaker.
Design is consistently described as fun, rugged, and compact with distinctive oversized volume buttons and multiple color options, balancing durability with a playful look.
Detail retrieval is a major strength. Reviews repeatedly praise how much vocal texture, instrument separation and fine nuance it extracts for such a small speaker.
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.
The A1 3rd Gen generally stays composed when pushed, with little change in character at high volume, though bass-heavy tracks and resonant surfaces can expose some strain or boom.
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.
Build quality is excellent, but the aluminum finish can scuff and reviewers are less comfortable throwing it around than a rugged JBL-style speaker.
Drop durability is consistently positioned as strong, with multiple reviews referencing drop testing around 1.5m or 5 feet and an overall rugged build.
Dust resistance is repeatedly cited as part of the IP67 rating, making it well suited for beaches, camping, and outdoor environments.
It handles dynamic swings capably for a small portable, but several reviews say larger or cheaper rivals still sound more explosive.
EQ customization is one of the best parts of the experience. The preset system and visual sound control are intuitive, effective and unusually enjoyable to use.
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.
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.
Its tonal balance is warm, rich and polished rather than strictly neutral, with standout mids and vocals, controlled bass and smooth highs. Some listeners wanted more treble bite or deeper sub-bass.
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.
Google-related integration is specifically mentioned as Google Fast Pair support in at least one review, making initial setup faster on compatible Android devices.
The leather strap looks and feels premium and makes carrying or hanging the speaker easy.
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.
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.
It gets impressively loud for a compact speaker and can fill a room or hotel space, but it is not the brute-force outdoor party option and some reviewers wanted more outright volume for the price.
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.
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.
Stereo pairing is a genuine strength. Reviews say it is easy to set up and useful in practice, including pairing with a 2nd-gen A1 in several cases.
No summary yet.
Multipoint support is a real plus and reviewers found switching between two devices simple and reliable.
Multipoint support is mentioned as available by some reviewers, enabling easy switching between two connected devices for shared DJ duties.
Sound disperses broadly and works well for room or table listening, though not every reviewer agrees it is truly 360-degree audio.
360-degree, omnidirectional output is a defining feature and is repeatedly praised for being consistent around the speaker and useful for small group listening.
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.
Pairing and setup are straightforward, helped by Fast Pair or Swift Pair support and a clean companion app.
Setup is widely reported as quick and painless, with easy Bluetooth pairing and, in one case, near-instant connection aided by Google Fast Pair.
Gen 3 drops Alexa entirely, which reduces smart-speaker appeal versus Gen 2, even if several reviewers said they did not miss it.
Speakerphone performance is generally good, with clear calls and solid voice pickup, though some reviewers heard slightly processed edges to voices.
Multiple sources confirm there is no built-in microphone, so it cannot be used for phone calls or speakerphone use.
The status LEDs work, but they are fairly subtle, and a couple of reviewers wanted them larger or more obvious.
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.
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.
Sustainability stands out for the category thanks to repairability, a replaceable battery and Cradle to Cradle certification.
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.
USB-C charging is widely praised as a key quality-of-life improvement over prior generations and is consistently present across reviews.
Value for money is the most debated part of the A1 3rd Gen. Many think the sound, materials and longevity justify the premium, but value-minded reviewers still see better sound-per-dollar from cheaper JBL and other larger rivals.
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.
Its IP67 rating is consistently treated as trustworthy for poolside, shower and beach use, and several reviewers mention quick dunk-style tests without issue.
Water resistance is a major strength, repeatedly cited as IP67 and suitable for showers, poolside use, and accidental submersion within the rating limits.
It is portable enough for bags and travel, with reassuring heft, but it is not featherlight or pocket-sized.
No summary yet.
USB-C works for both charging and wired audio, giving the A1 more flexibility than many Bluetooth-only rivals. USB-C wired playback is more than a checkbox feature. Reviews that tried it reported extra clarity, punch and definition compared with Bluetooth.
Multiple reviews explicitly note there is no wired AUX input, so listening is Bluetooth-only.
