Compare soundcore Rave 3S Speaker vs Ultimate Ears Wonderboom 4 Speaker

The Soundcore app is repeatedly called stable and genuinely useful, with fast connection, firmware updates, lighting control, and rich audio/karaoke settings that are easy to navigate.

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 advertised around 12 hours, but multiple reviews call it average for the size; with lights, BassUp, and higher volume, real-world endurance is often closer to a single party session (roughly mid single-digits of hours).

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.

Bluetooth audio codec support is limited (SBC is commonly cited, with AAC also mentioned), and reviewers explicitly call out the absence of higher-resolution options like LDAC/aptX.

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 performance is generally described as stable with low video lag; however, a few users mention occasional quirks (like multipoint handoffs or brief dropouts/behavior changes when powering mics).

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.

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 is commonly described as slow for the category, with about a 6-hour full recharge cited by multiple reviewers.

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.

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.

Build and styling are broadly praised as sturdy and modern, with a metal grille, textured housing, and thoughtful touches like mic holders and rubber rails for horizontal/spatial mode.

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 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.

Cleanliness at high volume is mixed: some reviewers report it staying composed with BassUp, while others hear high-frequency fuzz or bass/sub-bass distortion when pushed to maximum levels, especially outside.

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.

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.

EQ is a strong point: reviewers highlight multiple presets, a detailed 9-band EQ, BassUp, and vocal effects controls that make it easy to tailor both music and karaoke sound.

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.

Tuning favors party impact with strong bass and a forward, energetic sound; several reviewers note the deepest sub-bass and the very top end are less refined, but EQ and BassUp let you rebalance for different genres.

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 built-in handle helps, and mic storage is integrated, but multiple reviewers wish for additional handles or wheels; a few note the single-handle carry can feel awkward depending on how far you walk.

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.

Inter-speaker connectivity is a key feature: reviewers mention Auracast/Oracast for linking speakers and the ability to create a stereo setup with a second Rave 3S.

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.

For video use, reviewers generally report low perceived latency over Bluetooth, and some use the speaker as a simple TV/audio source via AUX when needed.

The LED light show is frequently praised as bright and customizable, with multiple presets and app control (including dimming/off options); lights are most visible from the front and can noticeably reduce battery life.

Across reviews, the Rave 3S is described as extremely loud for its size (200W class output) and easily fills small-to-medium rooms; it is still capable outdoors, though a few testers found it less dominant in open spaces versus larger, wheeled party speakers.

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.

It supports linking multiple speakers (Auracast/Oracast) and can form a stereo pair; direct long-term reliability reports are limited, but the feature is consistently present and straightforward to access in controls/app.

No summary yet.

Multipoint is supported in several reviews, allowing two devices to stay connected; switching works most of the time, though one tester reported occasional awkward handoffs in a busy party scenario.

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

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.

The speaker does not function as a power bank; the USB-C port is for charging the speaker itself, not for charging phones or other devices.

Setup is consistently described as easy: microphones auto-connect, on-speaker buttons mirror app controls, and most karaoke/light features can be used without deep configuration, aside from optional app tuning.

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

Smart/party features are the headline: AI vocal removal with adjustable strength (and in some cases an auto guide mode), vocal enhancement/reverb controls, and a spatial mode for wider playback; some reviewers note minor artifacts or level changes when the AI is active.

Multiple sources note there is no speakerphone/calling feature, which is typical for this kind of party speaker.

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

Several reviews appreciate the on-speaker battery/status indicators and the clear battery percentage readout inside the app.

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.

Out of the box it is primarily a mono, front-firing party speaker; laying it on its side enables a spatial mode that widens presentation, and true left/right stereo is achieved by pairing two units.

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 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 is a standout theme: the price is repeatedly justified by the included dual wireless mics, AI karaoke features, loud output, and customizable lighting, even with compromises in codecs, portability, and battery.

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.

Vocal intelligibility for music is generally good, but karaoke mic output varies by reviewer: some praise the included mics, while others note a noise gate/limiter, proximity sensitivity, or low-level hiss/static.

Protection is splash-level only (IPX4 in multiple reviews): fine for spills or light rain, but not intended for submersion or heavy weather.

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

At roughly 23 lb, most reviewers consider it manageable for short carries but not convenient for frequent transport; the lack of wheels is a recurring complaint.

No summary yet.

Connectivity is flexible for a karaoke boombox: reviewers cite a 1/4-inch mic/guitar input with gain controls plus a 3.5mm AUX input, alongside Bluetooth and USB-C charging; there are no TV-style ports like HDMI.

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