ANC is the main weakness. The open design limits sealing, so the effect is modest against chatter and steady noise and much less convincing against higher-frequency or sudden sounds, even if it appears somewhat improved over Buds 3.
Across reviews, ANC is strong for the price, especially against steady low-frequency rumble (traffic, engines), but it is less consistent against voices and higher-frequency clatter; a few reviewers still call it merely adequate compared with premium flagships. ANC offers manual and adaptive modes plus strength presets, but several testers report little real-world difference between levels, and changing presets from the earbuds is limited; others find the adjustability useful enough to dial in.
Android compatibility is strong, and Galaxy phones get the most complete experience. Non-Samsung Android users still get meaningful control through Samsung's software, but the best extras remain Galaxy-first.
Android support is strong, including access to LDAC and the full Soundcore app feature set on compatible devices.
Samsung's settings integration and Wearables app expose useful controls, EQ options, and ANC adjustments. The software feels feature-rich, though some advanced features stay exclusive to Galaxy phones.
The Soundcore app is a major value add: it is usually described as straightforward, stable, and essential for unlocking features like EQ, control remapping, and firmware.
aptX support is explicitly absent in multiple reviews, so users prioritizing aptX should look elsewhere.
Latency and A/V sync are generally reported as good, especially for video; gaming modes exist, but several reviewers say improvements are subtle and best for casual mobile gaming.
Bass is a standout strength, with reviewers repeatedly calling it punchy, warm, and satisfyingly deep for an open-fit earbud. It is not as textured as the Pro model, but it gives the Buds 4 a lively, full sound.
Bass tends to be punchy and fun, with some reviews noting a mid-bass lift; extension and sub-bass weight are more variable, and stock tuning can feel light down low for bassheads unless EQ is used.
Battery life is acceptable rather than exceptional at roughly 5 to 6 hours from the buds and up to 30 hours with the case. Reviewers treat endurance as serviceable, not a category advantage.
Battery life is a consistent highlight: real-world playback commonly lands around 6–8 hours with ANC and higher without it, with the case extending total time well beyond a full workweek for many.
Connectivity looks strong overall, helped by Bluetooth 6.1 and solid range in real-world use. The bigger limitation is not dropouts but that the smartest switching behavior is mostly reserved for Samsung-centric setups.
Bluetooth stability is usually reliable with quick pairing and solid range, though at least one review reports intermittent re-pairing frustration that may require forgetting devices.
Build and finish are seen as more refined than the previous generation, with a more polished stem design and cleaner execution. The Buds 4 feel premium enough for the price, though not especially rugged.
Overall build quality is solid for the price, though small durability concerns show up around case hinges and scratch-prone glossy interior surfaces.
The case earns positive marks for its flatter layout, translucent lid, and practical physical pairing button. It feels useful and better thought out than a generic accessory shell.
The case is compact and convenient with wireless charging, but some reviews flag lid/hinge security or imperfect closure that can risk accidental opening.
Charging features are premium for the price, typically including fast-charge boosts and wireless charging; real-world convenience is strong even if total runtime varies by codec and ANC.
Codec support is strong for the class (SBC/AAC with LDAC often available), but higher-quality modes can reduce battery life and may constrain other features like multipoint.
Comfort is one of the Buds 4's biggest wins, especially for listeners who prefer open-fit earbuds or have smaller ears. The only caveat is that the looser fit can require occasional readjustment.
Comfort is a strong point thanks to the small shells and light weight; long sessions are generally easy, though a few users report minor pressure or discomfort after several hours.
Design feedback is favorable overall: slimmer stems, a cleaner case, and a more polished look improve the presentation. The main knock is that the styling still feels very close to Apple's template.
Design is frequently described as stylish and premium-looking for the price, with a compact, pocket-friendly aesthetic that does not scream budget.
Multiple ear tip sizes are included (often five or six), improving fit odds; however, people with very large ear canals may still need third-party XL tips.
EQ flexibility is unusually strong for mainstream earbuds, with both a multi-band equalizer and preset options available. This gives listeners real room to tailor the sound signature.
EQ customization is one of the standout features, with extensive presets plus custom multi-band control and HearID-style personalization that can noticeably refine mids/highs and bass balance.
Find My-style locating is present in some accounts, typically using audible beeps rather than true GPS tracking, and works as a practical backstop for misplaced buds.
Tuning is described as broadly balanced and inoffensive, with the ability to correct the signature via EQ; some note small tonal shifts when ANC is enabled.
The Buds 4 separate vocals, synths, percussion, and layered mixes well for the class. They are not hyper-analytical, but they rarely sound congested or smeared.
Instrument separation and imaging are often highlighted as a strength, delivering good layering and placement for the money, though not at true flagship levels.
LDAC support is repeatedly called a key differentiator for Android users, enabling higher-bitrate streaming; expect higher power draw and the need to toggle settings in the app.
Maximum-volume clarity is mostly maintained, with limited distortion reported; tonal balance, rather than distortion, is the more common complaint at higher levels.
Noise reduction during calls performs better than expected and can suppress loud background noise effectively. The tradeoff is that strong processing can make the speaker sound a bit digitized.
Mic noise reduction can be effective at separating voice from traffic or café noise, yet wind processing artifacts and aggressive suppression can reduce naturalness or intelligibility for some callers.
Call quality is good in quiet spaces and usable in noisier ones, but it is not best-in-class. Voices remain understandable, though they can sound slightly muffled or processed compared with stronger premium rivals.
Call mic quality is mixed: indoor clarity is often fine, and some reviewers are impressed, but others report thin, muffled, or inconsistent voice pickup in louder or windy environments.
Midrange tuning is clear and well judged, keeping vocals and core instruments present even with the Buds 4's fuller bass. This helps the earbuds sound richer than many entry-level competitors.
Midrange is generally clear with decent vocal intelligibility, but a few reviewers note slightly veiled vocals or a cooler tuning that benefits from HearID/EQ tweaks.
Basic listening works across devices, but the overall experience is plainly Samsung-centric. iPhone users and people mixing Apple, Windows, and Galaxy hardware lose access to several of the best features.
Cross-platform support is good across iOS and Android, but the best codec features and some behaviors vary by platform (for example LDAC typically being Android-only).
Automatic switching is strongest inside the Galaxy ecosystem and notably less convenient elsewhere. Mixed-device users should expect more manual intervention than they would want at this price.
Multipoint/dual-device connectivity is commonly praised as smooth and dependable, but at least one source claims it is missing and others note tradeoffs (like dropping to AAC/SBC when enabled).
Passive isolation is weak because the open design does not create a proper seal. That physical limitation is a big reason the ANC never becomes truly class-competitive.
Passive isolation is generally above average with a good seal, providing a solid baseline even before ANC; fit-dependent leakage is the main limiter if tips do not seal well.
Preset EQ profiles are plentiful and generally useful, giving workable options for music genres and spoken word; most reviewers still recommend light personalization for best results.
Wear sensors are a weak spot: multiple reviews call out the lack of auto-pause/in-ear detection, which reduces day-to-day convenience compared with some rivals.
Setup and customization are straightforward on Galaxy phones and still manageable on other Android devices through Wearables. The biggest friction comes from Galaxy-only options rather than a confusing interface.
Setup is generally easy with quick pairing, but the feature set can feel dense; most reviewers suggest using the app to configure controls, codecs, and listening modes early.
Sound quality is the clearest reason to buy the Buds 4. Across the reviews, the earbuds are praised for rich tuning, strong bass, clear vocals, and a presentation that beats many direct price rivals.
Sound quality is widely praised for a sub-$100 set, with a clean, detailed presentation and lots of tuning flexibility; a recurring theme is that it is enjoyable rather than truly reference-grade for critical listening.
For everyday earbuds, the Buds 4 sound fairly open and spacious, especially with higher-quality Galaxy playback modes enabled. They do not sound huge, but they avoid the boxed-in feel common at this tier.
Soundstage is typically called wider than expected for compact buds, but still varies by listener and EQ, with some describing it as more in-head than expansive.
Spatial audio is present as a headline feature, but clear enthusiasm is limited. It adds another box to the feature list more than it defines the Buds 4 listening experience.
Fit stability is acceptable for regular daily use, but the open shape can shift enough to require adjustment. This is not the best pick for people who prioritize a locked-in feel.
Fit stability is generally good for daily use and light exercise, though the lack of stabilizing fins means heavy workouts and running can require occasional readjustment.
Touch and stem-based controls are a strength. Reviewers repeatedly call them easy to locate, responsive, and customizable, with the flatter stem helping usability.
Touch controls are customizable and usually responsive, but several reviewers mention occasional missed taps, lag, or finicky behavior that takes practice.
Transparency mode is feature-rich (often with full and vocal-focused options) and can work well for quick conversations, but opinions diverge on naturalness: some hear hiss, brightness, or a narrow sound window.
Treble comes through cleanly with good detail and vocal presence. Reviewers do not describe it as harsh or thin, which helps the Buds 4 avoid sounding brittle despite their lively tuning.
Treble detail is good for the price, yet multiple reviewers mention either a treble spike/snappiness or a slight roll-off and reduced sparkle depending on tuning and ANC mode.
USB-C charging is standard and universally present, with quick top-ups frequently cited as genuinely useful.
Voice assistant support is solid on paper, with access to Bixby and Gemini plus Galaxy-focused conveniences. It adds real hands-free utility, even if reviewers do not treat it as the product's main selling point.
Voice assistant integration is available but not always reliable, with reports of lag or misinterpreted commands on some platforms.
Peak volume is generally more than sufficient for most listeners, with at least one measured test placing it firmly in loud-enough territory without obvious strain.
IP54 is enough for sweat and light splashes, making the Buds 4 workable for everyday workouts and commuting. Still, the rating is not especially rugged and is a downgrade from tougher earlier protection.
The IPX4 rating is adequate for sweat and light rain but not for dunking or heavy water exposure; runners wanting more protection may prefer higher-rated alternatives.
Weight comfort is excellent, with the buds routinely described as lightweight and easy to forget once seated properly.
