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.
ANC is usually rated as strong and clearly improved, but not universally best-in-class; it excels more with steady noise than sudden sounds and remains behind the very top Bose, Sony, or Apple options for some listeners.
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.
These earbuds pair especially well with Samsung and Android devices, and many reviewers frame that ecosystem fit as one of the product's biggest selling points.
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 Galaxy Wearable experience is feature-rich and useful, but several reviews note that the best tools remain most valuable on Samsung devices.
One review notes that enabling the highest-quality Samsung audio mode can hurt lip-sync performance, making video playback less precise than standard settings.
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 described as deep, punchy, and well-controlled, but a minority of reviewers thought the low end could overpower some tracks without EQ tweaks.
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 serviceable rather than standout. Most reviews land around six hours per charge and see that as fine for everyday use, but short versus the longest-lasting rivals.
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 solid, with good range and few disconnect complaints, though one review did note occasional dropouts.
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.
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 redesigned case earns mostly positive marks for pocketability, easier docking, and the translucent lid, though a few reviewers found it blockier or more scratch-prone than ideal.
Charging convenience is strong thanks to USB-C and wireless charging support, and reviewers generally liked the case's day-to-day practicality.
Codec support is strong for Samsung owners thanks to SSC and UHQ options, but the experience is less compelling outside the Galaxy ecosystem where higher-end features are restricted.
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.
Long-session comfort is a major positive. Many reviewers wore the earbuds for hours on flights, work sessions, or daily use without significant fatigue.
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.
Samsung's new look is broadly seen as more polished and premium, with the flatter metallic stem and refined case helping the Buds 4 Pro feel more distinct and mature.
Samsung includes multiple tip sizes, but fit outcomes still vary widely; some reviewers got a strong seal quickly while others could not find a great match.
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 clear strength, with reviewers frequently praising the custom bands and the ability to tune the sound away from the stock profile.
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 frequently cited as a standout, with cleaner layering and better distinction between elements than earlier Galaxy Buds generations.
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.
Background-noise suppression during calls performs very well in most reviews, especially against wind, traffic, and loud ambient noise, even if the processed voice can sound a bit artificial.
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 good overall, with clear enough voice pickup for everyday use, but several reviewers heard some digitizing, fuzziness, or mild warble in tougher conditions.
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 performance is a strength, with vocals and core instruments coming through clearly and without being swallowed by the boosted low end.
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.
Outside the Samsung ecosystem, the Buds 4 Pro lose meaningful convenience and some premium features, so cross-platform users get a less complete product.
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 and device switching are a weak spot. Galaxy-to-Galaxy switching is convenient, but true cross-platform multipoint is missing or awkward.
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 depends heavily on fit: reviewers with a strong seal found it effective, while others said the tips failed to seal well enough for class-leading isolation.
Preset EQ options are generally well received, especially the Dynamic-style tuning, though they are not a full substitute for manual tweaking if you dislike the default balance.
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 not difficult, but one review noted a small learning curve because some controls moved from the old app-centered flow into Samsung's system settings.
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.
Across the review set, the Buds 4 Pro are consistently praised for rich, detailed, energetic sound, though a few reviewers found the tuning a bit bass-forward or Samsung-dependent at the top end.
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.
When reviewers commented on staging, they found the presentation surprisingly open and spacious for true wireless earbuds, especially with Samsung's higher-quality audio modes.
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 security is good for many listeners, but not universal. Several reviewers found the buds locked in well, while others reported slipping during movement or difficulty maintaining a seal.
Touch and stem-based controls are a strength. Reviewers repeatedly call them easy to locate, responsive, and customizable, with the flatter stem helping usability.
Pinch and swipe controls are usually considered responsive and easier to use than last generation, though a few people still found the gesture scheme awkward at first.
Transparency or ambient mode is one of the most consistently praised features, sounding natural and useful for conversations, announcements, and day-to-day awareness.
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 generally clear and lively with good sparkle, though a few reviews mention occasional high-frequency leak-through in ANC mode or a slightly uneven top-end balance.
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.
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 IP57 rating is repeatedly highlighted as a useful advantage for sweaty workouts, rain, and general durability, even though the buds are not meant for swimming.
