Bottom Line
Choose the Technics EAH-AZ100 for audiophile-leaning sound, strong adjustable ANC, and standout three-device multipoint; Skip if you need consistently natural call quality or the very most realistic transparency.
Best for
Audio-first listeners and commuters who want a wide, detailed presentation plus strong, tunable ANC and reliable three-device multipoint.
Not for
People who take frequent calls in noisy places and want the most natural mic tone, or anyone who wants a simple, set-and-forget earbud with minimal app tinkering.
Verdict
The Technics EAH-AZ100 is repeatedly praised for its highly detailed, spacious sound and unusually controlled bass, backed by a deep EQ and feature set. ANC is commonly rated top-tier and very adjustable, while battery life and true three-device multipoint are consistent differentiators. The tradeoff is consistency: call processing can sound robotic and one review reports severe call glitches, and transparency can be slightly hissy or less natural than the very best. If you prioritize sound quality and connectivity features, it’s an excellent premium pick. If calls are your daily priority, test with your phone and typical environments before committing.
Pros
-
USB-C charging is consistently supported and frequently mentioned as a modern convenience.
-
Where tested, audio-video sync is reported as excellent with minimal to no noticeable lag.

Bluetooth stability is generally reported as reliable with few dropouts across devices and environments.
-
Soundstage is a standout: multiple outlets describe an immersive, wide presentation that feels larger than typical earbuds.
-
Three-device multipoint is a major differentiator and is often described as seamless; occasional switching lag is mentioned but not common.
-
Instrument separation is frequently praised on busy tracks, helping the AZ100 stay clean and layered.
-
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.
-
Bass is repeatedly called deep and unusually controlled for true wireless, though one review found it can feel heavy or change with ANC settings.
-
Battery life is commonly reported around 10 hours with ANC on (AAC) plus substantial case recharges, with lower figures when using high-res modes.
-
Charging is praised for USB-C plus Qi wireless and quick-charge support; full recharge times are typically a few hours.
-
LDAC support is frequently highlighted for higher-quality Android streaming, with the usual battery-life tradeoff.
-
Codec support is strong (SBC/AAC plus LDAC and LC3/LE Audio features noted), appealing to both iOS users and Android audiophiles.
-
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.
-
EQ customization is a strength, often cited as an 8-band EQ plus presets that can significantly change the sound.
-
Comfort is widely rated high thanks to a smaller/lighter fit, though some users may still experience fatigue or fit variability over long sessions.
-
The Technics Audio Connect app is feature-rich (ANC, EQ, multipoint, spatial settings), but some reviews call the interface clunky or menu-heavy.
-
Multiple ear tip sizes are commonly included, helping most users achieve a seal, though tip choice remains key to fit.
-
Touch controls are responsive and highly configurable, with the main complaint being occasional over-sensitivity.
-
The earbuds are commonly cited as IPX4-rated for sweat and light rain, but not for heavy water exposure.
-
Dolby spatial audio/head tracking is supported and can add immersion, but some reviewers find it subtle or prefer it off for music.
-
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.
-
Voice noise reduction is often effective at cutting wind and background noise, though aggressive processing can create artifacts.
-
Treble is described as airy and detailed without harshness, but a few critics wanted more sparkle or presence.
-
The case is generally pocketable and premium-feeling, but some reviews mention weak magnets, slight rattle, or scratch/scuff issues.
-
Midrange is generally clear and natural for vocals, with occasional notes that bass-heavy mixes can push voices slightly back.
-
Case finish durability is mixed, with some noting scratches/scuffs and others calling it relatively scratch-resistant.
-
Call quality is mixed: many find it usable or improved, while others report robotic processing or, in one case, serious call glitches.
-
Preset EQ options are generally useful, though some (like extra-bassy modes) may be too much for neutral listeners.
-
Fit stability varies: many report a secure hold, while some reviewers experienced looseness or buds falling out during vigorous movement.
-
Design is viewed as premium and more compact than the prior model, though not everyone finds it the sleekest-looking option.
Cons
-
Find My/location features are present, but feedback varies; some appreciate the feature, while others complain the locating beep or accuracy is limited.

Setup is mostly straightforward, but the lack of a case pairing button and some app UX quirks can add friction.
-
Several reviews explicitly note aptX codecs are not supported.
FAQ
Does the Technics EAH-AZ100 support aptX codecs?
No. Reviews commonly list SBC/AAC plus LDAC and LC3/LE Audio features, and explicitly note aptX is missing.

Up to three simultaneous connections via Technics’ three-device multipoint, which many reviews describe as unusually seamless.
Is the noise cancelling as good as Bose or Sony?
Most reviews rate it near the top for everyday noise and rumble, but several still say the very best rivals can block more in the hardest scenarios.

Yes. The Technics Audio Connect app offers presets and an 8-band EQ, and multiple reviews say EQ can materially improve the default tuning for your taste.
