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.
Noise cancelling is repeatedly described as class-leading, with especially strong suppression of engine rumble and broad-spectrum everyday noise; a few reviews note minor hiss or occasional artifacts with sudden loud impacts, but overall performance remains top tier. Adjustability is strong via app modes and sliders, including custom levels and adaptive behavior (such as smoothing spikes), though some mode limitations and UI quirks are mentioned.
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 repeatedly framed as a strong use case, with modern Bluetooth features and higher-quality codec options that cater well to Android ecosystems.
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 Bose app is generally seen as essential and functional for modes, device management, and settings, though some workflows (like mode creation) can feel limited or slightly confusing.
aptX Adaptive (including higher-quality variants cited by reviewers) is a key advantage versus some rivals for Android listeners who want better Bluetooth audio performance when supported by their phone.
Audio/video sync is usually fine for casual viewing and even editing for some users, but multiple comments suggest latency is not ideal for competitive gaming or fast-reaction play.
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 is consistently described as deep, punchy, and satisfying; some listeners consider it aggressive or dominant, especially out of the box.
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 consistently called average for the category: typically around 6 hours with ANC, dropping with immersive/spatial modes, and supported by multiple case recharges.
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 generally reported as solid across iOS and Android devices, with few or no dropouts in typical use, though some reviewers mention earlier-gen complaints and suggest toggling certain features if problems appear.
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.
Earbud build quality is generally considered premium, with durability expectations aligned to the price; the case gets more mixed feedback on feel and refinement.
Controls are easy to learn and include useful gestures (notably swipe volume), yet multiple reviews mention finickiness and accidental activations; the ability to disable touch controls is an important mitigation.
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 frequently described as bulky and less premium-feeling than the earbuds themselves; some reviewers also note the buds can be awkward to retrieve.
Charging is a Gen 2 strong point thanks to wireless charging support, plus fast top-ups via the case; a few notes suggest wireless coil placement can be finicky on some pads.
Codec support is a highlight for many reviewers, especially for Android users, with modern high-quality options noted alongside broad device compatibility.
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 widely praised for long sessions, especially once tips and stability bands are dialed in; a consistent caveat is that the shell size may not suit the smallest ears.
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 polarizing: many like the sleek, modern look, but the buds are visually and physically large, which can be a problem for smaller ears.
Tip and wing options are helpful for achieving a strong seal, but multiple reviews note the included range is adequate rather than expansive given the premium price.
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 a frequent criticism: it is typically described as a basic 3-band tool with limited precision, which may frustrate listeners trying to meaningfully reshape the tuning.
Accessories commonly include multiple tip sizes and stability bands plus a charging cable; a few reviewers wish for extras like more sizes or a longer cable.
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 is repeatedly rated as strong, helping busy tracks stay organized and making details easier to pick out.
At higher volumes, clarity generally holds up well according to multiple impressions, though overall tonal preference still depends on how you feel about the bass-forward tuning.
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.
Noise reduction for calls is frequently praised (including AI-style voice isolation), yet a minority of measurements-based reviews report that wind and background sound can still bleed through depending on scenario.
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 quality is widely reported as improved versus earlier generations, often sounding clear and intelligible; however, some tests still find it can struggle in very windy or extremely noisy 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 presentation is generally clear enough for vocals and instruments, but opinions vary: some hear warmth and natural tone while others cite recessed or uneven mids that can affect certain voices.
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 use is broadly positive across phones, tablets, and computers; iOS works well, though several reviewers still note Apple ecosystem extras remain a separate advantage for AirPods users.
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 is a meaningful quality-of-life feature and is mostly described as seamless for switching between two devices, with occasional notes that pausing one stream before starting another helps.
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.
No summary yet.
Portability is mixed: the case is pocketable but noticeably larger than key competitors, and runners often find it inconvenient to carry during workouts.
Preset EQ profiles are described as basic and not always effective at fixing core tuning preferences, especially for listeners sensitive to boosted bass or treble.
In-ear detection and related sensors are supported and configurable; at least one review suggests turning detection off if it contributes to unwanted playback behavior or stutters in edge cases.
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 usually straightforward, but several reviews emphasize the app is effectively mandatory for fully managing features like multipoint, modes, shortcuts, and certain tuning behaviors.
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.
Overall sound is widely praised as rich, engaging, and detailed, though it is not tuned for strict neutrality; a few reviewers find the stock profile too boosted at the extremes and harder to correct due to limited EQ.
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 commonly described as roomy and spacious for earbuds, with immersive modes able to expand the sense of space further (sometimes with tonal side effects).
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.
Spatial/immersive audio features are robust and can sound more natural than many implementations, but not everyone prefers the processing, and it typically reduces battery life.
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 security is a major strength thanks to stability bands/wings, with several reviews calling them suitable for workouts and even running, though some users mention footstep thud in ANC mode.
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 responsiveness is generally strong and often praised for quick gesture recognition, but sensitivity can lead to accidental triggers during fit adjustments or certain activities.
Transparency/Aware mode is generally clear and natural, with useful loud-spike handling in some implementations, but several reviewers still place it behind the very best competitors and note occasional hiss or wind sensitivity.
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 is often described as crisp and detailed without obvious harshness for many, though some reviews report boosted regions that can fatigue sensitive listeners and note limited EQ control to tame it.
USB-C charging is standard and widely appreciated, with fast-charge behavior commonly referenced for quick listening time boosts.
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 support is present via shortcut customization, with practical use reported (including Google Assistant), though it is not typically positioned as a headline differentiator.
Volume output is frequently described as loud and satisfying, with enough headroom for travel and commuting environments.
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.
An IPX4 rating is repeatedly cited as sufficient for sweat and light rain, appropriate for workouts but not for full submersion scenarios.
