Compare Technics EAH-AZ100 Earbuds vs Samsung Galaxy Buds3 Pro Earbuds

ANC is widely rated top-tier for everyday noise and transit rumble, but several reviews stop short of calling it the absolute best in the category. Noise control is highly adjustable, with adaptive ANC plus granular sliders that let you tune intensity and reduce pressure effects.

ANC performance is polarized: several reviewers find it strong and effective, while others rate it merely average and still behind the best-in-class models, especially for certain environments. The buds offer multiple noise modes and adaptive behaviors. Some like the options, but multiple reviews describe adaptive switching as inconsistent or not clearly different from other modes.

Android compatibility is strong overall, and the experience is best on recent Samsung phones where the newest codec and AI features are available.

The Technics Audio Connect app is feature-rich (ANC, EQ, multipoint, spatial settings), but some reviews call the interface clunky or menu-heavy.

The Galaxy Wearable app unlocks core features like EQ, noise modes, and Find My tools. Reviews repeatedly warn that iPhone support is limited and some features are Samsung-only.

Several reviews explicitly note aptX codecs are not supported.

Several reviewers explicitly note there is no aptX support, which is a drawback for some Android users who want broader high-quality codec compatibility.

Where tested, audio-video sync is reported as excellent with minimal to no noticeable lag.

Video and gaming latency is generally reported as good, helped by a low-latency or game mode in some setups, though availability can depend on device and settings.

Bass is repeatedly called deep and unusually controlled for true wireless, though one review found it can feel heavy or change with ANC settings.

Bass is frequently described as boosted and punchy. Many enjoy the impact, but a few reviewers call it thumpy or overcooked without EQ.

Battery life is commonly reported around 10 hours with ANC on (AAC) plus substantial case recharges, with lower figures when using high-res modes.

Battery life varies noticeably by reviewer and settings: some measured around 4.5 to 5 hours with ANC, while others report closer to 6 hours or more, and some tests cite longer runtimes. Reviews note the battery is not designed to be user-replaceable, so long-term serviceability is limited compared to more repairable designs.

Bluetooth stability is generally reported as reliable with few dropouts across devices and environments.

Bluetooth stability is generally strong, with few dropouts reported and solid range, though occasional stutters or device-specific quirks are mentioned.

Build quality is generally good with strong water resistance, though early QC chatter and fragile or finicky ear-tip swapping show up repeatedly.

The case is generally pocketable and premium-feeling, but some reviews mention weak magnets, slight rattle, or scratch/scuff issues.

The clear-lid case is generally compact and convenient, but a few reviewers dislike the feel, one-hand opening, or the fussiness of seating stems correctly.

Charging is praised for USB-C plus Qi wireless and quick-charge support; full recharge times are typically a few hours.

Charging is well rounded with USB-C and wireless charging. Some sources highlight fast top-ups or convenient reverse wireless charging support on compatible phones.

Codec support is strong (SBC/AAC plus LDAC and LC3/LE Audio features noted), appealing to both iOS users and Android audiophiles.

Codec support is solid for Samsung owners via Samsung Seamless Codec options, but limited for everyone else, with common fallbacks to AAC or SBC.

Comfort is widely rated high thanks to a smaller/lighter fit, though some users may still experience fatigue or fit variability over long sessions.

Long-wear comfort is widely praised thanks to the stemmed design and reduced ear pressure, but side sleeping can be uncomfortable and fit still varies by ear shape.

Design is viewed as premium and more compact than the prior model, though not everyone finds it the sleekest-looking option.

Design is divisive: many like the blade-stem look and lights, while others view it as too AirPods-like or slightly plasticky.

Multiple ear tip sizes are commonly included, helping most users achieve a seal, though tip choice remains key to fit.

Ear tips come in three sizes. Several reviews mention the swap process can be annoying and early units had tearing complaints.

EQ customization is a strength, often cited as an 8-band EQ plus presets that can significantly change the sound.

EQ options are unusually deep for mainstream earbuds, with a 9-band equalizer and presets called out as a major advantage for tuning the sound.

Find My/location features are present, but feedback varies; some appreciate the feature, while others complain the locating beep or accuracy is limited.

Find My and tracking features are improved with lights and alerts, but some reviewers still want UWB-grade precision and note occasional quirks.

Measured tuning is often reported as close to a modern target in mids and treble, with extra bass energy that can be dialed back via EQ.

Instrument separation is frequently praised on busy tracks, helping the AZ100 stay clean and layered.

Instrument separation is strong, with multiple reviewers noting they can track individual elements in busy mixes more easily than on older Galaxy Buds.

LDAC support is frequently highlighted for higher-quality Android streaming, with the usual battery-life tradeoff.

Multiple reviews point out there is no LDAC option, limiting hi-res codec flexibility outside of Samsung’s proprietary codec path.

Maximum volume is generally ample for typical listening. No major complaints surface, though the loudest levels can sound a bit strained in some accounts.

Voice noise reduction is often effective at cutting wind and background noise, though aggressive processing can create artifacts.

Noise reduction for calls is mixed: some tests show strong background suppression, while others struggle to pull much reduction without the right client or conditions.

Call quality is mixed: many find it usable or improved, while others report robotic processing or, in one case, serious call glitches.

Call mic quality is usually rated good to excellent, with clear voice reproduction in many tests; a few reviewers still describe it as only fine or slightly unnatural depending on device and conditions.

Midrange is generally clear and natural for vocals, with occasional notes that bass-heavy mixes can push voices slightly back.

Midrange is typically clean and articulate with good vocal detail, though some describe it as slightly recessed in a V-shaped tuning.

These earbuds work on many devices, but cross-platform value depends on how much you rely on Samsung-only features and the lack of a full iOS app experience.

Three-device multipoint is a major differentiator and is often described as seamless; occasional switching lag is mentioned but not common.

Multipoint and device switching are often limited to the Samsung ecosystem. Some reviews praise seamless Galaxy-to-Galaxy switching, while others note weak or missing multipoint for mixed-device setups.

Passive isolation is decent with a good seal, but it varies by fit and ear tips; some reviewers say it lags behind foam-tip competitors for blocking high-pitched noise.

Preset EQ options are generally useful, though some (like extra-bassy modes) may be too much for neutral listeners.

Sensors enable wear detection and convenience features in supported apps, with some reviews highlighting automatic pausing and posture or voice-detect behaviors.

Case finish durability is mixed, with some noting scratches/scuffs and others calling it relatively scratch-resistant.

Setup is mostly straightforward, but the lack of a case pairing button and some app UX quirks can add friction.

Setup is usually straightforward, helped by quick pairing and clear in-app controls, but some reviewers find the interface non-intuitive or note feature lock-in outside Samsung.

Reviews consistently praise the AZ100 for highly detailed, spacious sound with strong dynamics; a few note the default tuning can be bass-forward or benefit from EQ.

Across reviews, sound quality is a standout: a lively, detailed presentation with strong clarity and a generally wide, engaging mix that can compete with top-tier earbuds, especially after EQ tuning.

Soundstage is a standout: multiple outlets describe an immersive, wide presentation that feels larger than typical earbuds.

Soundstage is commonly praised as wider than average for in-ears, helping music feel more open and layered.

Dolby spatial audio/head tracking is supported and can add immersion, but some reviewers find it subtle or prefer it off for music.

Spatial and 360 audio features are included and can be fun, but reviews are mixed on immersion, head tracking accuracy, and real-world usefulness.

Fit stability varies: many report a secure hold, while some reviewers experienced looseness or buds falling out during vigorous movement.

Stability is often improved versus older Galaxy Buds, with many reporting a secure fit for workouts, but some testers still experienced easy dislodging depending on ear shape.

Touch controls are responsive and highly configurable, with the main complaint being occasional over-sensitivity.

Controls are a frequent talking point: many find pinch and swipe gestures responsive and precise, while others dislike the stem shape and the learning curve for consistent pinches or swipes.

Transparency/ambient mode is strong and adjustable, but some reviewers note hiss at higher levels, an unnatural voice-focused mode, or not enough outside sound for awareness.

Transparency mode is a highlight for many, described as natural and very clear, though a few note slight hiss or less realism than the very best implementations.

Treble is described as airy and detailed without harshness, but a few critics wanted more sparkle or presence.

Treble is crisp and revealing with good sparkle and detail. It can lean bright or forward for sensitive listeners, and some note a bit less refinement with ANC engaged.

USB-C charging is consistently supported and frequently mentioned as a modern convenience.

Voice controls and assistant integration are widely mentioned, including hands-free commands. Reliability is often praised, but setup and feature depth can vary by device and preferences.

The earbuds are commonly cited as IPX4-rated for sweat and light rain, but not for heavy water exposure.

With an IP57 rating, water and sweat resistance is consistently positioned as a strong point for workouts and daily use.
