ANC is frequently described as a standout for the price and, in some reviews, competitive with or better than more expensive Samsung models. However, at least one reviewer found it only marginal in very loud subway conditions, so expectations should be tempered versus best-in-class ANC leaders. ANC and ambient intensity are described as adjustable via Samsung settings/app controls, often with multiple levels or sliders. Some note the lack of certain adaptive/conversation features found on higher-end models.
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.
Compatibility and feature completeness are repeatedly framed as best on Samsung Galaxy phones (and often Samsung tablets/TVs), acceptable on other Android phones with some limitations, and highly restricted on iPhone.
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.
The Samsung Wearable/settings integration is portrayed as essential for unlocking key features like EQ, ANC/ambient tuning, firmware updates, Find My, and AI features. iOS support is repeatedly called very limited beyond basic Bluetooth audio.
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.
Multiple reviews explicitly state there is no aptX support.
At least one hands-on video reviewer reports no noticeable lip-sync delay when watching video, suggesting good real-world A/V sync in common streaming playback.
Bass is generally portrayed as well-defined with a mild boost; it competes with outside noise without dominating vocals for most listeners. Some reviewers wanted more bass punch, while others felt the boosted low end contributed to a muddier presentation on certain tracks.
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.
Battery life is consistently characterized as average for the category: roughly mid-4 to ~6 hours with ANC on depending on volume, with totals rising into the mid-20s to ~30 hours with the case and ANC off.
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.
Connectivity is generally described as stable in testing, with quick pairing for Samsung phones and smooth day-to-day use. Auto-switch behavior is ecosystem-dependent and not always perfect.
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.
Build quality is usually described as sturdy and premium-feeling for the price. A recurring caution is that the case lid may loosen over time with regular use.
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.
Pinch and swipe controls are generally liked for reducing accidental touches, but the stem shape and required pinch force are cited as less ergonomic than some rivals, and can shift the earbuds slightly in-ear.
The case is generally described as compact and pocket-friendly with a firm snap early on, but there are repeated cautions that the hinge/lid may loosen with time, and wireless charging is repeatedly noted as missing.
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.
Charging is USB-C only with repeated notes that wireless charging is not supported and that a charging cable may be omitted in the box. Some hands-on impressions report a roughly around-one-hour top-up for the case in normal charging.
Codec support is consistently described as SBC and AAC plus Samsung Seamless Codec (SSC) for compatible Samsung devices; this is framed as a Samsung-first product choice that affects cross-device consistency.
Comfort is generally rated highly for long listening sessions, helped by low earbud weight and a familiar stem-based in-ear fit, though comfort still depends on tip sizing and seal.
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.
The matte, understated look is repeatedly praised, with many liking the premium-feeling Buds 3 Pro-like shape while noting the absence of decorative blade lights as a cost-saving simplification.
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.
Ear tip options are a common complaint: some sources mention three sizes, others only two additional sizes, and multiple reviewers wish an XL tip existed. Getting a tight seal is repeatedly emphasized as critical for best sound and ANC.
Reviews commonly mention multiple EQ presets plus a custom multi-band EQ (often described as 9-band) to tailor sound. Some note the absence of certain personalized tuning tests found on competitors.
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.
Find My-style locating is mentioned through Samsung tools (often tied to SmartThings/Find My Earbuds). Some sources note the lack of ultra-wideband precision finding compared to higher-end models.
One detailed measurement-focused review describes the default tuning tracking a target curve closely, with only a modest bass emphasis and less problematic treble emphasis than some pricier siblings.
Included accessories typically cover multiple ear tip sizes, but several reviews criticize limited sizing (sometimes only small/large beyond the default) and frequently mention that a charging cable is not included.
Instrument separation is generally described as competent, but at least one long-term reviewer felt fine detail and separation lag behind some competitors and the Buds 3 Pro.
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.
Multiple reviews explicitly state there is no LDAC support.
Clarity at higher volumes is usually reported as solid with limited obvious distortion, but best results are tied to a good seal and reasonable listening levels; some note performance assumptions change with volume settings.
Background noise reduction for calls is often praised as improved and effective in office/street noise, though very windy scenarios remain a weak spot and a few reviewers describe occasional muffling depending on conditions.
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.
Call mic quality is commonly reported as a strong point, with clear voice pickup and generally good intelligibility in everyday environments. Wind can still degrade clarity in harsher 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.
Midrange performance is commonly praised for clear, present vocals and good everyday clarity, helping speech and music remain intelligible even at moderate volumes.
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.
They connect to multiple platforms via Bluetooth, but advanced features and seamless switching are consistently described as ecosystem-dependent, working best inside Samsung’s device lineup.
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.
True multipoint is repeatedly noted as missing. Samsung Auto Switch can approximate device switching within the Galaxy ecosystem but does not replace simultaneous two-device connections.
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.
Sealed ear tips are repeatedly credited for strong passive isolation and more consistent fit compared with unsealed designs. Seal quality varies by ear shape and included tip sizing, and some users may need third-party tips.
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.
Preset EQ profiles are generally seen as useful and well-implemented, with several reviewers preferring specific presets (for example, Dynamic) for a more engaging sound.
Wear sensors are mentioned, but auto-pause behavior is described as limited or inconsistent (some note it does not auto-pause music reliably, or is used mainly for calls rather than playback controls).
Matte finishes on buds/case are repeatedly described as less prone to fingerprints and smudges than glossier alternatives.
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.
Sound is widely described as smooth, balanced, and surprisingly high quality for the price, with some reviewers preferring it to pricier Samsung buds. A minority found it less detailed or a bit muddy/v-shaped out of the box, and Samsung-only codec/settings can make a noticeable difference.
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.
Several reviews note a pleasantly wide, open soundstage for the price, with decent separation between elements, though not always matching more premium dual-driver models.
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.
Samsung 360 Audio/spatial features are mentioned as supported, but head tracking is repeatedly noted as missing on the FE. The effect is described as situationally enjoyable but sometimes diluting sound on music.
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.
Stability is generally good for everyday wear with a proper seal, but at least one review warns they may not be rock-solid for high-impact activities like running compared with winged/fin-style designs.
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.
Pinch-and-swipe control responsiveness is often described as good once learned, but at least one reviewer reports finicky tap behavior (especially double/triple actions) and occasional jostling due to the light fit.
Touch and stem-based controls are a strength. Reviewers repeatedly call them easy to locate, responsive, and customizable, with the flatter stem helping usability.
Transparency/ambient mode is consistently rated as clear and natural for conversations and awareness, with adjustability. A light hiss/white noise at higher gain levels is mentioned by some reviewers.
Treble is often characterized as clear but not overly fatiguing compared with some flagship tunings. A few reviewers reported the highs could sound splashy or less controlled depending on fit, EQ, and expectations.
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.
Voice assistant integration is frequently referenced via hands-free Gemini and Samsung Bixby on compatible devices, alongside Samsung/Google AI features like interpreter and translation.
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.
Multiple reviewers describe very high loudness potential, sometimes bordering on too loud, making it easy to overpower noisy environments when needed.
Buds 3 FE are repeatedly described as IP54-rated, suitable for sweat and light rain but not submersion. One included older Galaxy Buds FE review highlights much lower water resistance for that different model, underscoring model confusion in mixed sources.
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.
