Compare Samsung Galaxy Buds 4 vs EarFun Air Pro 4 Plus

Sound is one of the strongest parts of the Buds 4, with frequent praise for clarity, detail, vocals, and overall richness. The catch is fit: when the buds loosen, bass and balance can deteriorate sharply.

Sound quality is the product's strongest consensus win, with rich, detailed and unusually mature performance for the price. A few reviewers wanted more refinement, but many thought it competed surprisingly close to much more expensive earbuds.

Passive isolation is inherently weak because the buds do not seal the ear canal. External sound leaks in easily, which also makes ANC and bass performance more dependent on positioning.

Passive isolation is a useful foundation for ANC. Reviewers who discussed the seal found it capable of blocking a fair amount of outside sound even before electronic cancellation is applied.

Width is inconsistent: UHQ playback can sound impressively expansive, but broader testing finds the unsealed design limits convincing spatial width when fit is less than ideal.

The stage is generally wide and spacious for budget earbuds, helping music feel open and immersive. A few reviewers still found it narrower than premium alternatives or wider than it is deep.

Samsung Seamless Codec can provide near-lossless wireless playback on compatible Galaxy devices, giving Samsung users a higher-quality audio path than standard Bluetooth modes.

Lossless-oriented codec support is impressive for a budget model, but reviewers were careful about its limits. It can improve the available wireless quality with compatible devices without turning Bluetooth into truly wired lossless playback.

ANC is the biggest technical compromise of the open design. Many testers and buyers found it weak or unstable without a seal, though several users reported strong noise reduction when the buds stayed seated well.

Noise cancellation is the main point of disagreement. Some reviewers found it impressively effective on steady low-frequency noise, while several others called it average, confusing to configure, or clearly behind the strongest rivals.

Background-noise rejection is usually a strong point, with several tests showing voices staying clear through traffic, crowds, white noise, or loud music. A smaller number of users reported poor noise handling during calls.

Microphone noise reduction works well in ordinary indoor or moderately noisy settings, but heavy wind and busy streets expose its limits. Background suppression can also make the user's voice quieter or less stable.

Day-to-day use on a Galaxy phone showed no noticeable latency problems, making video playback and ordinary media use feel properly synchronized.

Low-latency and gaming performance is generally strong. Game Mode often brought audio close to the action, although Bluetooth still leaves enough delay or directional imprecision to limit competitive use.

Spatial depth is limited by the unsealed design, and reviewers caution against expecting a strongly three-dimensional or immersive presentation.

Soundstage depth is weaker than width. Reviewers described the presentation as relatively flat or merely adequate in front-to-back depth even when the overall stage remained spacious.

Bass can be punchy, deep, and even surprisingly powerful when the fit is right, but it is highly seal-dependent. Several reviewers heard the low end thin out, turn muddy, or fade as the buds shifted.

Bass is one of the sound profile's strengths: deep, punchy and generally well controlled without swamping the mids. A minority found the default low end a little thick or less forceful than expected.

Spatial audio divides opinion. One user calls it genuinely cool, while another avoids it because upmixing can warp music, making its value highly preference-dependent.

There is no dedicated spatial-audio processing, but reactions to that omission are mostly mild. Some reviewers missed the feature, while others felt the natural width and depth made artificial spatial modes unnecessary.

When seated correctly, the Buds 4 reproduce timbre reasonably well and present a balanced consumer-friendly tuning. Fit instability is the main factor that can disturb that consistency.

The default tuning is usually described as balanced, warm and natural rather than aggressively V-shaped. A few reviewers heard too much brightness or bass, but the overall frequency balance earned positive marks.

Support experiences after early failures were extremely poor in the two customer reports: both describe getting little useful help, including a disputed warranty and an unresolved serial-number issue.

Firmware support earned positive comments when updates arrived during testing and fixed real issues. Reviewers saw the active update cadence as a reassuring sign that EarFun is still refining the product.

Value is contentious. Galaxy-focused features and strong sound justify the price for some, but many buyers say the poor fit, modest battery, or weak ANC makes cheaper or Pro alternatives a smarter purchase.

Value for money is the strongest point of agreement. Reviewers repeatedly say the combination of sound, battery life, codecs and customization delivers far more than the sub-$100 price suggests.

Galaxy-to-Galaxy Auto Switch can be excellent and nearly instant, but true cross-platform Bluetooth multipoint is missing. Users moving between Samsung and non-Samsung devices may need manual switching.

Multipoint is usually convenient and reliable, with some reviewers calling switching seamless or flawless. A smaller group encountered stutters or instability, particularly when combining two-device use with LDAC.

Auracast is viewed as a useful forward-looking feature that can tap into compatible public or shared Bluetooth LE audio broadcasts as adoption grows.

Auracast is mostly viewed as a welcome future-facing extra rather than an everyday necessity. Reviewers like seeing it at this price even though several had little opportunity to use it.

Samsung's SSC/UHQ codec support is one of the stronger ecosystem perks, delivering high-quality 24-bit/96kHz playback that reviewers say can make an audible difference.

Codec breadth is exceptional for the price, with reviewers repeatedly praising the unusually complete set of modern wireless audio options. That flexibility is especially valuable for Android users and audio tinkerers.

The lack of built-in silicone tips or meaningful size adjustment is a major weakness. Buyers with a poor fit have little way to improve grip, seal, or stability without aftermarket add-ons.

The broad ear-tip selection helps accommodate different ear sizes and was repeatedly useful for achieving a secure seal. Reviewers with small ears in particular benefited from the extra sizing choices.

Fit is highly polarizing but skews strongly negative. A minority find the open shape comfortable and secure, while many others cannot keep the buds properly seated even during ordinary movement.

Fit is generally secure and comfortable, with the revised oval tips helping many reviewers get a good seal. Individual ear shape still matters, and a few testers needed to experiment with sizes or experienced fit-related sensor quirks.

The revised Buds 4 design gets strong marks for looking cleaner, sleeker, and more premium than the previous generation. The brushed-metal styling and simplified stems are recurring visual highlights.

The familiar stem design is functional and often described as attractive or understated, but it does not hide the budget materials. Several reviewers liked the clean look while others called it plasticky or generic.

The earbuds are exceptionally light, and that low weight helps them sit without much strain during longer listening sessions.

Low weight contributes meaningfully to comfort. Several reviewers said the earbuds are light enough to forget during long listening or workouts.

Comfort depends heavily on ear shape. The light, tipless design is excellent for some people and works well for long sessions, while others report pressure, irritation, or pain within minutes.

Long-wear comfort is consistently strong. The light earbuds sit comfortably for multi-hour listening, commuting, workouts and gaming without the pressure or fatigue some reviewers experience with other ANC buds.

The buds often feel solid, premium, and capable of surviving drops, but long-term reliability is uneven. Multiple customers reported buzzing, weak output, microphone degradation, or complete failure within a few months.

Build quality is solid for the price but visibly budget-oriented. Reviewers generally trust the earbuds' durability while noting plasticky materials and a few case or hinge details that feel less premium.

The box feels sparse for the price. Multiple reviewers objected to the missing charging cable, and one also wanted basic printed guidance or a direct setup link.

The accessory package is simple but useful, especially the unusually broad selection of ear-tip sizes. Reviewers liked having enough fit options without unnecessary extras.

Stability is the dominant complaint. Dozens of buyers report slipping, loosening, or outright falls during walking, chewing, exercise, or even sitting still, although a minority say the buds stay secure in their ears.

Physical stability is good for walking, running and workouts when the correct tips are used. Reviewers generally found the buds secure enough to stay in place through movement.

Loudness varies sharply by user and fit. Some testers find plenty of output, while many customers report the Buds 4 as unusually quiet or developing very low output in one ear.

Volume output is strong enough for demanding listening. The reviewer who assessed it directly found useful loudness around mid settings and plenty of headroom above that.

The move from IP57 on the prior generation to IP54 is consistently viewed as a downgrade. It still covers sweat and splashes, but offers less protection for rain, workouts, and water exposure.

The IP55 protection is widely viewed as sufficient for workouts, sweat, rain and everyday outdoor use. Reviewers treat it as a useful durability upgrade, while noting that the earbuds are not meant for submersion.

The transparent case lid looks good but attracts fingerprints and scratches very quickly, so keeping it clean and pristine takes extra care.

The matte finish can resist fingerprints well, but the case is not equally resistant to cosmetic wear. One reviewer specifically found it easy to scratch.

Overall reactions are split: strong sound, easy Galaxy pairing, premium styling, and useful smart features earn real praise, but the open fit creates enough stability, ANC, and consistency problems to ruin the experience for many buyers.

Overall satisfaction is very high: most reviewers consider these among the strongest sub-$100 earbuds and several gave unusually enthusiastic recommendations. The few reservations center on ANC, calls and budget-feeling materials rather than the core listening experience.

The buds can handle basic use across different devices, but the experience is much richer on Samsung hardware. Several advanced audio, assistant, and switching features are unavailable or less capable elsewhere.

The earbuds work across a broad mix of phones, computers and portable gaming devices, and reviewers generally had few compatibility problems. Android gets the richest codec options, but basic use remains strong across platforms.

Wear detection can become unreliable when the earbuds shift, occasionally making the system think a bud is no longer seated and dropping ANC in that ear.

Wear detection is inconsistent across reviewers. Some found it responsive and improved, while others experienced false pauses or fit-related detection problems.

The flatter clamshell case is widely praised for easier insertion, visibility, and a premium feel. A few users found it bulky, hard to pry open, or unusually tight, but the redesign is mostly well received.

The charging case is usually considered compact, practical and pocketable, but opinions on its feel are mixed. Some praised its sturdy design, while others found it slippery, awkward to open, or less premium than the earbuds' performance suggests.

Android use is a clear strength, especially on Galaxy phones where pairing and settings feel deeply integrated. Non-Samsung Android phones generally work well too, but some premium features remain Galaxy-only.

Android use is a good fit, especially for access to Fast Pair and higher-resolution codec options. Reviewers who tested Android generally found pairing and app support straightforward.

Ambient Sound is generally welcomed as a practical addition for awareness outdoors and quick conversations. One user found the transparency effect noticeably amplified rather than fully natural.

Transparency mode is useful for conversations and basic awareness, but it is rarely described as class-leading. Reviewers commonly called it decent or good enough, with less natural amplification than premium rivals.

Galaxy-exclusive UHQ playback is a genuine audio advantage: testers heard a more expansive presentation and a clear benefit from 24-bit/96kHz playback on compatible Samsung devices.

High-resolution wireless playback is a notable value advantage, with reviewers appreciating access to advanced codecs at a low price. The improvement over standard AAC can be subtle, but compatible sources can extract extra detail.

The compact case can disappear easily into a pocket for some users, but one buyer found the newer case noticeably larger and no longer comfortably pocketable.

Portability is good thanks to the light earbuds and generally compact case. A few reviewers thought the case could be slimmer, but it remains easy to carry in most pockets or bags.

Samsung Find offers useful location tools and proximity guidance, but the case lacks its own speaker, which makes audible finding less convenient than it could be.

The Find Headphones function is a useful practical extra for locating a misplaced bud. Reviewers who mentioned it treated the audible locator as a welcome feature in an already deep app.

Headwear can aggravate the already loose open fit: hoodies may knock the buds out, and a thick winter hat can interfere with microphone placement.

Headwear compatibility has a specific caveat: one reviewer found that wearing a beanie could accidentally trigger the touch controls and pause playback.

Very high volume can hurt tonal balance. Reviewers heard bass recede and upper frequencies become noticeably thinner or tinnier near the top of the volume range.

Clarity at extreme volume is only middling. Reviewers noted that treble can become hot or more aggressive near the top of the volume range even though normal listening stays controlled.

The unopened package arrived neatly presented, giving one buyer a positive first impression before using the product.

Packaging is neat and straightforward rather than luxurious. Reviewers found the unboxing organized and appropriate for the price.

Complex mixes remain clean and layered when the buds are seated well, with vocals and instruments staying distinct instead of collapsing into each other.

Instrument separation is a major sound-quality strength for the price. Reviewers repeatedly heard distinct instruments and vocals with good left-right organization even in busier mixes.

Translation performance is inconsistent: one tester found Korean back-and-forth surprisingly smooth, while another said normal-speed speech was not reliable enough. It looks useful, but not dependable for every conversation.

AI translation drew mixed reactions. It can handle basic exchanges reasonably well, but reviewers also found the workflow slow or awkward and questioned how accurately the feature is marketed.

Controls can be responsive, tactile, and easy to customize, but usability varies. Some users find the pinch-and-swipe system awkward, easy to trigger accidentally, or likely to disturb the already fragile fit.

Touch controls are customizable and usually responsive, but they are not universally loved. Some reviewers found them sensitive, fiddly or less satisfying than pressure-based controls.

The Smooth preset is specifically recommended for listeners who find the upper treble too sharp, giving the built-in presets practical value beyond simple novelty.

The large preset library gives plenty of quick tuning options, but quality and usability are mixed. Some reviewers liked the choice while others found the presets excessive, poorly organized, or less useful than the manual EQ.

Vocals and midrange detail are generally clear and well presented when the buds sit properly. In noisier real-world use, the open fit can let outside sound mask the mids.

Midrange performance is generally clear, full and natural, with vocals and instruments staying distinct from the bass. A few reviewers found the mids recessed, thin or less energetic, making this less unanimous than the bass praise.

Treble is often crisp, lively, and detailed, but the brighter upper range can become shrill for sensitive listeners and may sound thinner at very high volume.

Treble is usually clean, detailed and better resolved than on earlier EarFun models, helped by the balanced-armature driver. Depending on listener and volume, it can also sound too bright, too safe or slightly hot.

Battery life is one of the more common complaints. Around five to six hours is often described as merely adequate or disappointing, and some buyers reported much shorter runtimes, although a smaller group found endurance very good.

Battery life is one of the clearest strengths, with reviewers repeatedly praising long single-charge endurance and generous case reserves. Higher-bitrate codecs and ANC reduce runtime, but the overall result remains excellent for the class.

Charging is generally convenient and reliable, with wireless charging and reasonably quick top-ups earning praise. Minor complaints include the lack of an audible charging confirmation.

Charging is a strong convenience feature thanks to wireless charging and useful quick-charge performance. Reviewers repeatedly liked getting these extras in a budget-priced set.

Setup is one of the most consistent strengths. Galaxy pairing is usually immediate and seamless, while even Pixel and other Android users report quick, straightforward connection.

Initial pairing and everyday setup are generally easy, particularly with Fast Pair. The main usability complaint is the large number of ANC and tuning options, which can make the software feel more complicated than necessary.

The 9-band custom EQ and multiple presets provide unusually broad tuning flexibility for the standard model. Reviewers consistently appreciate having meaningful sound adjustment without stepping up to the Pro.

Sound customization is a standout feature. The 10-band EQ and personal profiles can meaningfully reshape bass, mids and treble, and several reviewers used them to correct aspects of the stock tuning they disliked.

Bluetooth 6.1 brings good range and stability in several expert tests, and Galaxy pairing is usually smooth. Customer experiences are less consistent, with reports of slow reconnection, short range, dropouts, and repeated disconnects.

Bluetooth performance is usually quick and dependable, with easy pairing and few dropouts in normal use. The main caveat is that demanding combinations such as LDAC plus multipoint can introduce instability.

Call quality is mixed. Many reviewers heard crisp, clear speech and strong pickup, but others found voices muffled, too quiet, inconsistent, or badly degraded after a few months.

Call quality is good for everyday use, with clear speech in quiet and moderate noise. It is not consistently flagship-level, and several reviewers reported weaker intelligibility or voice stability in wind and very loud surroundings.

The software offers extensive control over ANC, EQ, gestures, and other features. Most impressions are positive, although one reviewer disliked the Wearable app's heavy permission requests and another noticed a wrong Buds icon.

The EarFun Audio app is widely praised for its depth, useful layout, and extensive controls. A few reviewers found parts of it unstable or overly busy, but customization is a consistent strength.

aptX support is repeatedly treated as unusually generous at this price. Reviewers value having it alongside other high-resolution options, though the audible advantage depends on the source device and settings.

There is no low-latency wireless dongle, which limits suitability for serious competitive gaming. Game Mode helps substantially, but Bluetooth remains the underlying connection.

Head gestures are generally considered a useful hands-free addition for answering or declining calls and handling prompts. Reviewers who tested them found the feature effective and convenient.

The built-in microphone system can perform extremely well, with clear voice pickup and strong overall microphone performance in demanding use.

LDAC is valued for giving Android users another high-bitrate option and sometimes a little more body or detail. Its drawback is higher battery use and, in some setups, more connection instability or reduced multipoint flexibility.

USB-C charging is a welcome practical convenience, especially because it sits alongside wireless charging rather than replacing it.

The retained physical case button is welcome, but button placement is not universally easy. Reviewers with dexterity limitations and some other users found the small or side-mounted controls difficult to activate.

Hands-free voice controls and assistant access are useful for playback, messages, and phone tasks. Recognition can struggle in very loud environments, but the feature is broadly convenient.

Swapping the silicone tips is straightforward. The reviewer who directly assessed replacement found the process very easy.

Case-hinge confidence is a minor durability concern. Reviewers noted a less-secure lid and wished for a sturdier metal hinge, even though neither described an outright breakage.

Imaging is good for music, with convincing left-right placement and useful spatial cues. For competitive gaming, however, at least one reviewer found direction and distance too imprecise for pinpoint positioning.
