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.
Reviews consistently rate the ANC among the best in true wireless, especially for low-frequency rumble (planes, trains, HVAC). A recurring tradeoff is variability with fit and that a few rivals (notably Bose, and sometimes foam-tip Sonys) can edge it out in the toughest scenarios.
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 use is possible for basic audio and calls, but many Apple-only features and settings are unavailable or inconvenient. Multiple reviews argue the value proposition drops sharply if you are primarily an Android user.
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.
There is no traditional companion app; configuration lives inside iOS/iPadOS settings and feels deep and polished for Apple owners. On Android, feature access and management are reduced, making the experience feel clunkier.
The H2 chip is repeatedly credited for the generational jump in ANC, transparency processing, and feature behavior. Reviewers frame it as the backbone for the buds feeling smarter and more refined than earlier AirPods.
Multiple reviews explicitly note there is no aptX support, limiting options for Android hi-res/low-latency codec users.
Latency is generally fine for video and typical gaming use, and Apple touts particularly low-latency behavior in its own ecosystem (notably with Vision Pro). Like most Bluetooth earbuds, it is not a universal low-latency solution across every platform.
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 widely called strong and satisfying with good sub-bass presence for an in-ear seal. Some critiques mention it can be less tight or less dominant than bass-forward competitors depending on track and preference.
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.
Most sources cite around 6 hours on a charge with ANC, with some tests measuring longer; it is good but not always class-leading versus the longest-lasting rivals. The case adds multiple recharges and quick top-ups are repeatedly called useful. Reviewers note the batteries are not user-replaceable, which limits the practical lifespan of daily-use earbuds. This is treated as an industry-wide weakness, but it is still a real long-term ownership tradeoff.
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.
Connectivity is generally described as stable with very few dropouts in typical use. A couple long-term anecdotes mention occasional imbalance or drops after impacts, suggesting real-world reliability depends on handling and environment.
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.
Build quality is generally solid for daily use, with durable-feeling hinges and hardware across reviews. The glossy plastics can pick up scuffs, and long-term cosmetic wear is a more common complaint than functional breakage.
Pinch/press controls on the stems are widely seen as intuitive and less annoying than tapping earbuds. The main nit is that volume swipes can feel slightly fiddly at times, depending on technique.
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 earns praise for size and features (speaker, lanyard loop, and wireless charging options). Downsides include that it can feel slippery and prone to scratches or cosmetic wear over time.
Charging is praised for flexibility (wireless pads, MagSafe, and Apple Watch puck support) and fast case top-ups. USB-C is welcomed on the newer case, but Lightning on older variants is a frequent complaint or reason to wait.
Codec support is intentionally narrow (AAC/SBC for most devices), which frustrates hi-res-focused buyers. Several reviews note specialized low-latency/lossless behavior tied to Apple Vision Pro, but it does not broadly solve hi-res streaming on phones.
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 recurring strength, with many users wearing them for hours without hotspots and preferring them to bulkier alternatives. Fit still varies by ear shape, with a few noting slight pressure, looseness, or movement during talking/eating.
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 described as iconic and modern, though some dislike being limited to white. The stem-based look is divisive aesthetically but ties into better controls and mic placement.
Four ear tip sizes (including XS) help fit a wider range of ears, and seal quality strongly affects performance. Some reviewers still wish for XL tips or recommend third-party foam tips for a tighter seal.
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.
A consistent complaint is the lack of a true manual EQ: most tuning is handled by Adaptive EQ and limited iOS options rather than adjustable bands. Several reviewers contrast this with rivals that offer full EQ control, making AirPods less flexible for tweaking bass/treble to taste.
Find My support, aided by the U1-equipped case and built-in speaker, is a standout convenience feature for locating lost buds/case. A small number of anecdotes mention occasional connection hiccups, but overall sentiment is strongly positive.
The frequency balance is commonly characterized as neutral-to-crowd-pleasing, aided by Adaptive EQ and fit-dependent tuning. Most reviewers find it consistent and natural, even if not fully customizable.
The box contents are considered adequate, including multiple ear tips and a charging cable. The most common accessory complaint is the lack of an XL ear tip size rather than missing essentials.
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 frequently highlighted as a strength, keeping mixes organized and easy to follow. A couple comparisons still place the very best rivals slightly ahead in ultimate layering.
LDAC is not supported, so Android users looking for LDAC-based hi-res streaming should consider alternatives.
Multiple reviews say the earbuds can get loud without falling apart, keeping bass and detail intact. A few listening notes mention minor clarity softening at extreme levels rather than obvious distortion.
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 performs well in loud environments (office, transit), keeping speech understandable. Some recordings can reveal light processing artifacts or occasional distortion depending on conditions.
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 often rated at the top of the category, with clear voice pickup and strong intelligibility. A few reviewers describe the mic as only a modest improvement over other AirPods or slightly thin in tone.
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 and vocal presence are generally natural and clear, helping podcasts and calls sound intelligible. Some testing notes mention mild clarity loss only at very high playback levels.
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.
Pairing with Windows/Android generally works, and some reviewers game or take calls on PCs successfully. The strongest experience remains within Apple’s ecosystem, where switching and features are much richer.
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.
True multipoint across platforms is limited; seamless switching shines inside the Apple ecosystem but does not replace full multipoint behavior on Android/Windows. For multi-device Apple users, the iCloud handoff experience is consistently praised.
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 strong with a proper seal and contributes meaningfully to overall noise reduction. Some users still prefer deeper-inserting foam tips on competitors for maximum passive blocking.
Portability is frequently praised: the buds and case are compact, pocket-friendly, and easy to carry all day. This convenience is often cited as a reason to choose them over over-ear ANC headphones.
Sensors and auto-wear detection are generally described as reliable and central to seamless play/pause and mode behavior. They also enable software features like adaptive listening modes and personalized profiles.
Multiple long-term comments note the white, glossy plastics and case can show scuffs, scratches, and staining/yellowing. Many users mitigate this with a protective case or by being careful with pockets and drops.
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 and daily use are frequently described as effortless for Apple owners thanks to Magic Pairing and automatic switching. The convenience advantage diminishes on non-Apple devices where features and updates are harder to access.
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 tuning is praised as balanced, clean, and easy to enjoy across genres, with a polished, safe presentation. A minority of long-term/audiophile-focused reviewers call it slightly compressed compared with high-end wired gear.
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 width is unusually spacious for in-ears and becomes more enveloping with Spatial Audio features. A repeated caveat is that depth and openness still trail top open-back/over-ear references.
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 Audio is frequently called immersive and especially compelling for movies and Apple Music/Atmos content. Opinions split on everyday value: some love the envelopment, while others see it as a gimmick or find personalization finicky.
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.
Stability is generally strong for workouts and daily movement, with most reports saying they stay put. Edge cases include loosening during extended talking or chewing for some wearers.
At least one review calls out the use of sustainably sourced materials as a plus. It is not a dominant buying factor in most evaluations, but it is viewed positively.
Touch and stem-based controls are a strength. Reviewers repeatedly call them easy to locate, responsive, and customizable, with the flatter stem helping usability.
Stem gestures and volume swipes are considered a major usability improvement and usually register reliably. Some users still report the occasional missed swipe or a learning curve for consistent volume adjustments.
Transparency is repeatedly described as class-leading and close to totally natural in feel. Adaptive Transparency helps tame sudden loud sounds, though a few testers notice a touch of added noise or processing in some situations.
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 mostly described as smooth and non-fatiguing with little to no sibilance. It is not the most sparkling or analytical top end, but it avoids harshness across reviews.
The USB-C case is viewed as the most practical refresh because it simplifies charging with modern Apple devices. Several reviewers recommend buying the USB-C version specifically or waiting if you want one cable for everything.
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.
Hands-free Siri integration is fast and convenient for Apple users. A few long-term notes mention it can be intrusive at home when Siri on the earbuds responds instead of room-aware smart speakers.
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 IP54-rated buds and case are widely viewed as good protection for sweat, rain, and light splashes. Reviewers still emphasize they are not waterproof and should not be submerged or rinsed under a faucet.
