Bottom Line
Choose the soundcore Rave 3S if you want a loud, bassy party speaker that turns any song into easy karaoke. Skip it if you need true waterproofing or a lighter, wheeled boombox for frequent travel.
Best for
Karaoke-first households and backyard hosts who want big volume, punchy bass, and instant sing-along features without buying separate microphones or a dedicated karaoke rig.
Not for
Anyone who needs true waterproofing, high-res Bluetooth codecs, or a lighter party speaker with wheels and longer real-world runtime at high volume.
Verdict
The soundcore Rave 3S is built for parties first: it gets extremely loud, hits hard with BassUp, and the light show plus two included wireless mics make karaoke effortless. The Soundcore app is a strong companion, with deep EQ control and quick access to vocal effects and AI vocal removal. The tradeoff is refinement and ruggedness: Bluetooth codec support is basic, it is only IPX4 splash resistant, and real-world battery life can drop fast when you crank volume, lights, and bass. If you want a fun, self-contained karaoke boombox for home, backyard, or casual events, it delivers big value.
Pros
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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).
-
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.
-
Several reviews appreciate the on-speaker battery/status indicators and the clear battery percentage readout inside the app.
-
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.
-
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.
-
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.
-
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.
-
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).
Cons
-
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.
-
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.
-
Charging is commonly described as slow for the category, with about a 6-hour full recharge cited by multiple reviewers.
-
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.
-
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.
-
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.
-
Multiple sources note there is no speakerphone/calling feature, which is typical for this kind of party speaker.
FAQ
Does the AI vocal removal work on any song?
Reviews report it works on most streamed tracks and offers adjustable strength, but it is not studio-perfect and can introduce mild artifacts or level changes on certain songs.
Can it play in true stereo?
One unit plays mostly mono; you can enable a wider spatial mode when it is laid on its side, and a true left/right stereo setup requires pairing two Rave 3S speakers.
How long does the battery last in real party use?
While the spec is up to 12 hours, several reviewers found that high volume with lights and BassUp can cut runtime to a single party session, often in the mid single-digit hours.
Is it waterproof enough for pool parties?
It is IPX4 splash resistant for spills and light rain, but multiple reviews caution against submersion or heavy water exposure.
Can it charge my phone from the speaker?
No. Multiple reviews note the USB-C port is for charging the speaker only and does not act as a power bank.
What inputs does it have for mics or instruments?
Reviews cite a 1/4-inch input for a mic or guitar (with gain/level controls) plus a 3.5mm AUX input, alongside Bluetooth for wireless playback.
