Compare Technics EAH-AZ100 Earbuds vs OnePlus Buds 3

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 good for the price but not unanimous: several reviews call it strong in Max/Smart modes, while others describe it as average or clearly behind key rivals. Expect solid low-frequency reduction, with more variance on mid/high chatter and wind. Most reviewers note multiple ANC strength options (Mild/Moderate/Max plus Smart/adaptive). Smart can be handy, but lower settings may feel much weaker than Max and the adaptive shifts are not always obvious.

Android support is strong thanks to Fast Pair, broad feature access in HeyMelody, and LHDC availability on compatible phones. Non-OnePlus Android devices may need the app for full control.

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

The HeyMelody app (or OnePlus system settings) delivers broad control over modes, EQ, and features. Experiences range from polished and fast to occasionally glitchy, especially when the app fails to detect the buds reliably.

Several reviews explicitly note aptX codecs are not supported.

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

Video lip-sync and general A/V timing are typically good, and low-latency/game modes help in demanding scenarios. Some gaming use can still show slight delay in fast shooters depending 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 a defining trait: often described as powerful and punchy, sometimes even thunderous. Whether it is a plus or a minus depends on your taste, and several reviews suggest using EQ/BassWave to moderate it.

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

Real-world battery is usually around 6.5 to 7 hours with ANC on and closer to 10 hours with ANC off, matching most manufacturer claims. Heavy feature stacking (ANC + LHDC + spatial) can noticeably reduce runtime.

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

Baseline Bluetooth stability is generally solid in everyday use, with rare reports of app-connection hiccups or slower initial pairing rather than persistent dropouts.

Build quality is generally good for the price, with solid fit and finish and durable day-to-day handling. A few reviewers flag that the buds are not especially rugged or that glossy parts show wear like fingerprints.

Control mapping is flexible in the app and most gestures work reliably. A few reviews dislike the lack of pressure-squeeze controls or note that default mappings may require customization to feel complete.

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

The case is typically described as compact and pocketable with a decent hinge and finish. A few reviews call the plastic feel less premium or note it can be a bit slippery when removing buds.

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

Charging is fast and generally reliable, with quick-charge behavior repeatedly mentioned. The main downside is the lack of wireless charging on the case.

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 strong for the tier (SBC/AAC plus LHDC 5.0) and generally works well. However, some testing suggests very high LHDC bitrates can be unstable and can cost battery.

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

Comfort is a consistent strength: the buds are lightweight and many reviewers report long-session comfort. Fit can feel slightly loose for some ears, so tip selection matters.

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

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

The box typically includes three tip sizes, which covers most ears but not all; some reviewers wish for extra-large tips or more varied options.

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

EQ support is a major strength: multiple presets plus a custom multi-band EQ are widely praised for meaningful tuning, though a minority say changes can feel subtle depending on the preset and listening habits.

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 features are typically audio-based (playing a sound) rather than full location tracking. Useful for nearby couch-cushion situations, less helpful for true lost-and-gone scenarios.

Frequency response out of the box is commonly described as V-shaped rather than neutral. With the right preset or custom EQ, several reviewers say it can get much closer to balanced listening.

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

Instrument separation is often praised for this class, helped by the dual-driver design and tuning tools. Not every review calls it exceptional, but most agree it is above average at the price.

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

LDAC is not supported; multiple reviews point to LHDC as the hi-res option instead. If you specifically want LDAC, this model is a mismatch.

Clarity at high volume is good overall, though several reviews warn that treble can get harsh or sibilant when pushed toward the top end of the volume range.

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

Background-noise handling on calls is frequently praised, with several reviews noting strong suppression of chatter and environmental sounds. Wind handling is good but not universally perfect across all reports.

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

Call quality is often rated very good for the price, with voices coming through clearly. A minority describe it as merely adequate rather than class-leading.

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

Midrange presence is generally decent but can feel recessed compared to the bass and treble in the default tuning. Some reviewers find vocals clear, while others want more natural mid emphasis.

Cross-platform support is better than many budget buds: iOS users get the app and most core features, but hi-res codec advantages and some behaviors may vary by device ecosystem.

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

Multipoint is frequently highlighted as a standout convenience feature, with several reviewers calling it excellent or flawless for switching between two devices. Using multipoint can reduce available hi-res bandwidth on some setups.

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

Preset profiles are generally useful (with some reviewers preferring certain presets as closer to balanced). Bass-leaning presets and BassWave can be fun but may not satisfy listeners chasing a reference curve.

Wear detection and other sensors generally work as expected for pausing, mode toggles, and personalization tests, though performance can vary by ear fit and configuration.

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

Glossy or chrome-like surfaces tend to pick up fingerprints and smudges, which multiple reviewers call out. The case finish is often less prone to marks than the earbuds.

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

Setup is usually straightforward with Fast Pair on Android, but a few reviewers report slower pairing or extra friction when installing/using HeyMelody on non-OnePlus phones.

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.

Overall sound quality is widely considered strong for the price, with an energetic, consumer-friendly tuning and plenty of detail for casual listening. A few reviewers still categorize it as merely good-not-great versus flagship sets.

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

Soundstage is generally moderate with a sense of space that improves with spatial modes, but it is not universally described as wide or holographic in standard stereo playback.

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

Spatial or 3D audio is polarizing: some reviewers find it immersive and a big value add, while others call it underwhelming or artificial, and it may not behave consistently across apps/devices.

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

Stability in the ear is good for most users and workouts, but not perfect: a handful of reviews mention needing occasional readjustment, especially with sweat or a looser seal.

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

Touch and swipe controls are generally responsive and feature-rich (including volume gestures). Some users report occasional mis-taps or finicky behavior when moving or when the touch area is hard to locate.

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 generally sounds natural and usable, but quality varies: some find it close to best-in-class for conversations, while others say it still muffles speech or is not clearly better than ANC.

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

Treble is usually described as lively and detailed, though it can become sharp, sibilant, or fatiguing at higher volumes for some listeners.

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

USB-C charging is standard and consistently present across reviews, with no major complaints about the port itself.

Maximum loudness is a frequent positive: many reviewers note it gets very loud without needing to push the volume far. This helps in noisy environments but can tempt unsafe listening levels.

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

The IP55 dust and water rating is a meaningful plus for rain and sweat, and reviewers generally treat it as dependable for everyday exercise. It is not intended for submersion.
