Compare Soundcore by Anker Space A40 Earbuds vs Samsung Galaxy Buds 4

Reviewers generally found ANC strong for the price, especially against low, steady noise, though several noted weaker performance against voices, high frequencies, or premium ANC competitors.

ANC is available, but reviewers consistently treat it as limited by the open-fit design; one comparison piece expects improvement over Buds 3, while hands-on reviews still call it modest or not serious noise blocking.

Android users were singled out for benefiting from LDAC and broad device compatibility, while iOS remained limited to other codecs.

Android support is strong for everyday use, especially on Galaxy phones, and non-Samsung Android users can still use the Wearables app, though some Galaxy-only features remain locked down.

The Soundcore app was widely praised for useful controls, customization, EQ, and feature access, with only minor complexity or multi-device app caveats.

The app and settings experience is broad on Samsung and Android, with Wearables support for non-Samsung Android phones and Galaxy settings integration for Samsung users.

Video sync and gaming latency were mostly reported as solid, with several reviewers finding minimal or no noticeable delay.

Auracast is explicitly included among the shared features across the Buds 4 lineup.

Bass was usually described as punchy, steady, or adequate, but some reviewers wanted deeper sub-bass or found the default tuning too bass-heavy.

Bass earns positive notes across reviews, ranging from punchy and crunchy to loud, wide, fuller and more refined.

Battery life was one of the strongest areas, with most reviewers reporting long sessions and strong case endurance despite LDAC or ANC reducing runtime.

Battery life is serviceable rather than standout, with reviewers citing 6 hours without ANC, 5 hours with ANC and 30 hours via the case.

Bluetooth performance was mostly stable and quick, but one reviewer had frustrating re-pairing issues and another noted manual disconnect hassles.

Bluetooth support is a strength because the Buds 4 include Bluetooth 6.1, which reviewers connect to range, stability and future-proofing.

Build impressions were generally positive for the buds and case materials, though SoundGuys criticized the case hinge security.

Build impressions are positive: reviewers describe a premium feel, refined stems and a cleaner physical design.

Hi-res playback is a Galaxy-centered strength, with UHQ and 24-bit Hi-Fi audio noted when paired with compatible devices.

Case feedback was split: many liked the compact, premium-feeling case and charging support, while others criticized hinge/lid security or closure.

The case is viewed positively for its translucent lid, updated flat-bud layout and physical pairing button.

Charging was praised for wireless charging, USB-C, quick-charge usefulness, and a strong charging case, with few complaints beyond battery mode tradeoffs.

Charging evidence centers on the case reserve, with reviews citing up to 30 hours of total listening time through the charging case.

Codec support was viewed positively because LDAC joins AAC and SBC, though aptX was only factually absent and not scored.

Codec and high-quality audio support is represented by UHQ and 24-bit Hi-Fi playback on compatible Galaxy devices, not by aptX or LDAC.

Long-use comfort was a consistent strength, with most reviewers finding the buds light and wearable for hours, though a few reported pressure or fit-dependent comfort limits.

Comfort is a clear strength in the Tom's Guide review, including for small ears.

Design was consistently described as sleek, compact, premium-looking, or stylish for the price.

Design feedback is broadly positive, describing the Buds 4 as polished, premium and more refined, even while acknowledging the AirPods-like stem style.

Fit was usually secure with a good seal, though reviewers emphasized tip choice and one found the stock XL tips inadequate.

Fit evidence is mixed to weak: the open design can require adjustments and lacks a seal, though one review still found the earbuds comfortable.

The included tip selection was usually praised for offering many sizes, but one reviewer with large ear canals found even the largest tips too small.

Ear tip options are effectively absent because the Buds 4 use an open-fit, no-silicone-tip design.

EQ customization was a standout strength thanks to many presets, custom EQ, HearID, and frequent praise for tuning flexibility.

EQ customization is strong, with access to a 9-band equalizer in the app/settings experience.

Find My support was treated as a useful bonus, though the evidence centered on beeping-style device finding rather than GPS tracking.

Frequency response was viewed as enjoyable and often balanced for the price, but not fully neutral or accurate enough for critical listening.

Head gestures are a supported modern control feature, with reviewers noting nods or shakes for calls, Bixby prompts and notifications.

The only direct hinge evidence was negative, with SoundGuys saying the case hinge was not tight enough.

Instrument separation was praised in multiple reviews, with instruments and mix elements described as clear, well placed, or easier to distinguish.

Instrument separation is supported by a detailed listening note about synth effects layered between bassline and percussion.

Integrated microphones were generally considered useful and capable, especially for calls or ANC, though mic quality varied in separate call-quality scoring.

The mic hardware is described as upgraded, with multiple microphones and voice pickup units.

Independent left/right bud use was praised as seamless, with no connection break reported.

LDAC was repeatedly treated as a meaningful advantage for Android or hi-res Bluetooth listening, though it reduced battery life in some testing.

The one direct maximum-volume clarity test was positive, noting no distortion in the lows at top volume.

Microphone noise reduction was mixed: some reviewers praised voice isolation in noise, while others found ambient handling weak or inconsistent.

Microphone noise reduction is a strength, with reviewers saying background roar, white noise and wind/background noise are reduced or blocked.

Call microphone quality was the clearest weakness, ranging from loud and clear to thin, muffled, serviceable, or poor depending on reviewer and environment.

Call quality is generally good and intelligible, though one review says the voice can sound muffled and another notes processing in noisy places.

Midrange comments were mostly positive for vocals and clarity, though a few reviewers found mids veiled, dull, or slightly lacking.

Midrange clarity is praised through adequate mids, clean vocals and strong mids/treble performance.

Cross-device compatibility was positive, with reviewers using phones, laptops, tablets, iOS, and Android without major platform-specific barriers.

Multi-platform compatibility is limited: basics work outside Galaxy, but advanced features and seamless switching are restricted by ecosystem.

Multipoint reliability was a major strength, with reviewers repeatedly describing device switching as seamless, reliable, or essential.

Multipoint is context-dependent, working best in the Galaxy ecosystem and improving in Samsung contexts while remaining limited for non-ecosystem devices.

Passive isolation was considered good when fit was right and helped ANC performance, though it remained dependent on a proper seal.

Passive isolation is weak because the open-fit, no-seal design lets external noise seep in.

Portability was a consistent strength, especially the small case and compact buds that fit pockets easily.

Preset EQ quality was useful but mixed: some presets worked well, while bass-boost style presets were criticized for limited or muddy results.

Preset EQ support is good, with six presets including speech and instrumental options.

Sensors were a repeated weakness because multiple reviewers missed wear detection or auto-pause.

The only smudge-resistance evidence was positive, noting the case finish should resist visible fingerprints.

Setup and software simplicity were generally praised, with reviewers calling the app simple, the guide sufficient, or setup easy.

Setup is simplest on Galaxy devices through Bluetooth/settings integration and remains available through Wearables on non-Samsung Android.

Sound leakage evidence was limited but positive, with one reviewer saying the buds kept sounds private.

Overall sound quality drew strong praise across the review set for clarity, balance, detail, and value, with only critical-listening caveats.

Sound quality is the product's strongest theme, with reviewers calling it richer, cleaner, clear, balanced and better than expected.

Soundstage depth is supported by listening impressions of deeper low-end and expansive playback.

Soundstage width was usually praised as wide, spacious, or well-imaged, though one reviewer found the stage narrow.

Soundstage width is supported by the UHQ soundscape and wide bass impressions.

Spatial audio is present as 360 Audio/360° sound, though one reviewer does not personally use it.

Stability was generally strong for walking, workouts, and daily use, but one reviewer warned against serious running or sprinting.

Fit stability is a concern because one review calls out constant fit adjustments from the open design.

Touch controls were mixed: several reviewers found them responsive and customizable, while others reported delays, missed gestures, or sensitivity issues.

Controls are well regarded, with swipe, press and pinch gestures described as straightforward, precise and easy to locate.

Transparency mode was mixed, from very good vocal/ambient awareness to bright, tinny, hissy, or limited adjustability.

Transparency is improved by the addition of a proper Ambient Sound mode.

Treble was often clear and detailed, but some reviewers noted sibilance, thin cymbals, reduced sparkle, or upper-register sharpness.

Treble clarity is praised alongside mids, with reviewers noting crunchy highs and strong mids/treble performance.

USB-C was positively tied to easy recharging in the one directly opinionated USB-C quote.

Value was the strongest consensus point, with nearly every reviewer framing the Space A40 as a standout bargain for features and performance.

Value is positive for Galaxy or Android users because reviewers frame the $179 Buds 4 as compelling and able to challenge bigger rivals.

Voice assistant support was split, with one reviewer reporting poor Google/Siri behavior while another found the microphones sensitive enough for requests.

Voice assistant support is clear, with Bixby and Gemini assistance plus head-gesture responses to Bixby prompts.

Volume output was considered more than loud enough by reviewers who discussed it, including one who said loud-listeners would be satisfied.

Water and sweat resistance was viewed as useful for rain, sweat, and workouts, but IPX4 was also described as limited or not especially rugged.

Water and sweat protection is adequate but not rugged, with IP54 covering sweat and splashes while dropping below Buds 3's IP57 rating.

Weight comfort was strongly positive, with reviewers repeatedly noting light buds that disappear or avoid fatigue.
