Compare Samsung Galaxy Buds 4 Pro vs Technics EAH-AZ100 Earbuds

ANC is generally useful to strong, with several reviewers praising it, while others note it is not always class-leading or fit-proof.

ANC is broadly strong and often near flagship level, though several reviewers say it still falls short of the very best Bose-style silence.

Android and Samsung compatibility is useful but restrictive, since the best features require Galaxy devices and some are Android-only.

Android compatibility is praised for LDAC, fast pairing, and strong ANC value with Android phones.

The app and settings experience is feature-rich, but one review called the Galaxy Wear app bare-bones and another notes a learning curve.

The app is mostly praised for useful controls, customization, stability, and EQ access, despite some complaints about layout.

aptX support is effectively absent based on evidence that the buds are not compatible with AptX hi-res formats.

aptX support is a weakness because one reviewer specifically wished Qualcomm aptX codecs were included.

Latency evidence is mixed: common codecs are said to lag minimally, but hi-res settings and missing low-latency modes add caveats.

Video sync is mostly strong, with two reviewers reporting zero or no visible lag, while one notes a slight delay with some codecs.

Auracast support is clearly present and repeatedly noted as useful for public or shared broadcasts.

Auracast support is a concern in one scored review because the reviewer criticizes its absence.

Bass is a consistent strength, described as deep, energetic, punchy, and extended, though one review found it too strong on some tracks.

Bass is widely praised for depth, control, punch, and low distortion, with only one review criticizing the default balance as too boomy.

Battery life is adequate but not a standout, with repeated six-hour ANC evidence and several concerns versus rivals.

Battery life is consistently a strength, with reviewers praising long ANC runtime and major improvement over the AZ80.

Bluetooth support is modern and generally stable, centered on Bluetooth 6.1, with one review noting some dropouts.

Bluetooth reliability is consistently praised, with reviewers reporting stable connections and no meaningful dropouts.

Build quality evidence is limited but positive, including a reviewer saying the redesigned case feels more durable.

Build quality is praised as premium, tactile, mature, and a substantial step forward.

Hi-res playback is a strong Galaxy-specific feature, with repeated 24-bit/96kHz UHQ or SSC evidence.

Hi-res playback is praised in the one scored review, where LDAC/FLAC listening brought more detail, solidity, and space.

Pinch and stem controls are generally effective, though one review found the pinch area somewhat painful or awkward.

Control remapping is praised as unusually flexible and useful across the app and earbuds.

The carry case is generally praised for its clear lid, magnetic feel, easier bud placement, and visibility.

Case quality is mixed: it is compact and pocketable, but multiple reviewers criticize weak magnets, rattle, scratches, or bland styling.

Charging is a strength because reviewers cite wireless charging plus wired USB-C case charging.

Charging is viewed positively where evaluated, especially wireless charging and case convenience.

Codec support is strong inside the Samsung ecosystem, but non-Samsung devices fall back to common lower codecs.

Codec support is praised for LDAC/LC3 breadth, but the absence of aptX is called a mild limitation.

Comfort is widely praised, including long listening sessions, flights, and multi-hour use without fatigue for several reviewers.

Comfort trends positive thanks to smaller, lighter ergonomics, but fit fatigue and bulk remain concerns for some ears.

Design sentiment is positive overall, with reviewers calling the buds premium, sleek, more polished, and better differentiated.

Design and aesthetics are generally praised as premium, sleek, compact, or classy, though a few reviewers find the look plain.

Fit is polarized: several reviewers found a secure seal, while others could not get the tips to seal or stay put.

Eartip fit is generally good with the right size, but some reviewers report looseness, bulk, or falling out.

Ear-tip options are included, but proprietary tips and fit complaints reduce the practical flexibility.

Ear tip options are considered useful and generous, especially for finding the right fit across ear sizes.

EQ customization is a major strength, with a nine-band EQ, custom mode, presets, and Wear app adjustment all supported.

EQ customization is a clear strength, with many reviewers praising the eight-band control and meaningful tuning options.

Find My support is clearly present through Find My Earbuds and map-based finding references.

Find My support is useful for peace of mind, though one reviewer is disappointed by the location behavior.

Frequency-response evidence is mixed: detail and clarity improve, but one review notes bass/high balance issues that may need EQ.

Frequency response impressions are mixed: one review calls it strange, while others praise accuracy, balance, and low distortion.

Head gestures are supported for calls and assistant interactions, though some reviewers had not fully tested them.

Included-accessory evidence is limited to bundled ear tips and documentation.

Included accessories draw criticism where reviewed because foam tips are missing despite multiple silicone tip sizes.

Instrument separation is repeatedly praised through comments about separated instruments, centered guitars, and textural detail.

Instrument separation is a standout strength, with reviewers hearing layers, voices, and complex arrangements as distinct and clearly placed.

Integrated microphones are clearly present and usable, but mic impressions range from ordinary to very good.

Independent left/right earbud use is praised as convenient and useful when scored.

LDAC support is effectively absent based on evidence that the buds are not compatible with LDAC formats.

LDAC is received positively for higher-quality playback and better sound from compatible Android or hi-res sources.

Lossless support is mixed because Samsung hi-res playback is supported, but one review stresses true lossless Bluetooth is not available.

Reviewers who addressed clarity at output levels described clean, dynamic, distortion-free playback.

Maximum-volume clarity is praised for staying clean and distortion-free even at high levels.

Microphone noise reduction is a clear strength in wind, traffic, and background-noise scenarios, though not every voice sample was perfect.

Microphone noise reduction is polarized: several reviewers praise wind and background suppression, while one reports failed clarity and cutouts.

Call quality is usable to strong, but evidence is mixed because some reviewers heard fuzziness, digitization, or fit-related variability.

Call quality is mixed, ranging from serviceable or excellent in some reviews to choppy, robotic, or poor in others.

Midrange clarity is generally strong, with vocals, mids, and clear signatures receiving positive notes across several reviews.

Midrange and vocals are generally described as clear, detailed, warm, and more forward than the previous model.

Multi-platform use is limited because non-Samsung devices can leave the product feeling incomplete.

Multi-platform compatibility is praised because the app and customization work across iOS and Android.

Multipoint is a weakness outside Samsung devices, with several reviews noting no true multipoint or manual switching limitations.

Multipoint is a major strength, with reviewers repeatedly praising reliable switching and three-device connectivity.

Passive isolation is strong when the tips seal well, but the benefit depends heavily on fit.

Passive isolation is viewed positively when the tips seal well, with reviewers noting isolation even before ANC is active.

Portability is strong, with the case described as small, pocketable, and easy to carry.

Portability is strong because the case is repeatedly described as pocketable, small, and easy to carry.

Preset EQ evidence is positive, especially for Samsung's Dynamic profile, which reviewers used to add punch or emphasize strengths.

Preset EQ quality is mostly positive, especially Direct, Dynamic, and Treble+ modes, though SuperBass+ is too heavy for one reviewer.

Lighting customization is not a feature here; evidence says the lighting element is gone.

Sensor-like smart features are strong, especially voice detection, siren detection, and adaptive behavior.

Sidetone support is present and lets users hear their own voice in the buds.

Smudge resistance is a weakness because the transparent case section shows scratches and fingerprints.

Setup and software access are workable, but reviewers note a learning curve around where controls live.

Setup and software simplicity are mostly positive, but the lack of a physical pairing button adds friction for one reviewer.

Sound leakage is a weakness in the one scored review, which says loud music can be heard in a quiet room.

Review evidence is strongly positive on overall sound, with reviewers calling the audio excellent, very good, or among Samsung's best.

Reviewers overwhelmingly praise the AZ100's sound as clear, detailed, musical, and high-end, though one review found the stock tuning odd.

Soundstage depth is usually strong, with reviewers praising depth, immersion, and layering, though one long-term reviewer wanted more depth.

The available evidence points to a wider, more expansive stage rather than a cramped in-ear presentation.

Soundstage width receives strong praise, with reviewers describing the presentation as spacious, broad, expansive, and room-like.

Spatial audio support is clearly present through 360 audio and head tracking, though some features are Android or Samsung-focused.

Spatial audio is mixed: reviewers appreciate Dolby/head-tracking support, but several find it merely decent, distracting, or less clear than stereo.

Stability is strong for reviewers whose ears matched the shape, with evidence of perfect fit and secure wear.

Stability is mixed: several reviewers found the fit secure, while others would not trust it for vigorous movement.

Touch and gesture controls are mostly praised as responsive and easy to use once learned.

Touch controls are generally responsive and customizable, though sensitivity and personal preference create some mixed reactions.

Transparency and ambient modes are a highlight, often described as natural, clear, or useful for conversation.

Transparency mode is mixed: some find it natural or useful, while others hear hiss, over-processing, or weaker situational awareness.

Treble is mostly praised for crispness, clarity, and sparkle, but one lab-style review found the highs weaker than ideal.

Treble is usually considered clear, airy, detailed, and non-harsh, though one review says the default tuning lacks high-end content.

USB-C support is consistently evidenced through case port mentions.

Value is context-dependent: Samsung users often get strong value, while non-Samsung users and upgraders face more caveats.

Value is mixed-to-positive: reviewers like the premium feature set and sound, but several note the high price and strong competition.

Voice assistant support is broad, with Bixby, Gemini, Google assistant, and built-in voice controls mentioned.

Voice assistant integration is limited in coverage but works reliably where tested or described.

Direct evidence is limited but positive, with one review saying maximum volume is far higher than needed.

Volume output is praised as top-tier and very loud in the reviews that discuss it.

Water and dust resistance is a strong point thanks to repeated IP57 evidence.

Water and sweat resistance is adequate for workouts or rain, but one reviewer cautions against heavier rain exposure.

The earbuds are described as light, with roughly 5g weight contributing to comfort.

Weight comfort is praised because the earbuds feel better distributed, light, and easier to forget during use.
