Positioning and Price
The TWS headphone market is now highly saturated. Compact form factors, high prices, and a standard feature set – such as competent sound quality, acceptable battery life, and active noise cancellation – have become baseline expectations rather than differentiators. Meaningful progress in this category typically comes only from sustained engineering effort and long-term research, which makes such attempts worth closer examination.
With the EAH-AZ100, Technics enters 2025 positioning a fully wireless model that aims to compete directly with established flagship offerings. Based on its technical approach and overall execution, the AZ100 is designed to stand on equal footing with the strongest players in the premium segment, rather than relying on incremental updates or marketing-driven distinctions.
In the premium headphone segment, with pricing starting around $350 / €320, the discussion no longer revolves around basic features. Competition here has long shifted away from headline specifications toward engineering decisions and execution quality. This is a category dominated by brands such as Bowers & Wilkins, Apple, and Bang & Olufsen.
Among the key competitors, the Bowers & Wilkins Pi8 stands out at approximately $421 / €398, primarily due to its carbon-based drivers. The Bang & Olufsen Beoplay EX, priced around $336 / €318, combines a distinctive Scandinavian design with a notably clean sound signature. Apple AirPods Pro 2 are also worth including in this comparison: despite a lower price point of about $249 / €235, they remain strong competitors thanks to tight ecosystem integration and effective noise cancellation.
Each of these models has a clearly defined character. The Technics EAH-AZ100 competes with them on different terms, relying less on ecosystem advantages or design emphasis and more on its Hi-Fi heritage and precise sound tuning, supported by detailed configuration options in the companion applications.
Package contents
Technics approached the packaging of the AZ100 with Japanese pragmatism: everything is concise, environmentally friendly, but with a noticeable emphasis on the professional segment. When you open the box, you won’t find any unnecessary ‘luxury’ air, but instead you’ll get the most complete bundle necessary for proper initial launch and long-term operation.
What’s in the box:
- Charging case and earphones: the package includes the TWS earbuds and a compact charging case in a deep blue finish. The outer paper wrap features a QR code that links to the companion app, which is required for initial setup, sound profile configuration, and firmware updates.
- Extended set of ear tips (silicone): this is one of the most important parts of the package aside from the earphones themselves. Technics includes four sizes of silicone tips, ranging from XS to L. This allows for a more precise fit tailored to individual ear canal anatomy, which is critical not only for comfort but also for passive isolation and accurate low-frequency reproduction. A tighter, more consistent seal directly affects both bass performance and the effectiveness of active noise cancellation – a topic addressed later in the review.
- Short USB-C to USB-C charging cable.
- Documentation: complete set of paperwork – warranty card, safety instructions and connection guide.
The ear tip tray also deserves specific mention. It features clear size markings, which makes it much easier to manage and compare tips – particularly for users who experiment with fit to fine-tune soundstage and tonal balance. Overall, the package gives the impression of a professional tool, with each component included for a clear and practical purpose.

Design and Ergonomics
The Technics EAH-AZ100 charging case features a matte premium finish that resists fingerprints and maintains a clean appearance in daily use. The material quality and overall build are solid and well executed. The design is minimal: a USB-C charging port is located on the rear, and the lid hinge operates smoothly without noticeable play. Each earbud weighs just 5.9 g, which is particularly important for long listening sessions, as the low weight helps reduce fatigue over extended use.
The touch panels feature a sophisticated concentric ‘spun metal’ texture with an elegant gold logo.
The internal engineering is carefully considered. Four gold-plated contacts ensure reliable charging in the case, wear-detection sensors trigger instant auto-pause when an earbud is removed, and clear L/R markings make it easy to distinguish between the left and right sides.
The earbud housings are ergonomically shaped to fit the anatomy of the ear, providing a deep and secure fit. The porous structure of the sound ducts not only protects against debris but also helps shape an accurate acoustic soundstage.
Support for Qi wireless charging and an IPX4 rating (earbuds only) allows the AZ100 to be used safely in humid conditions and charged wirelessly.

Software
Technics’ proprietary Audio Connect app serves as a full-featured control center for the AZ100 earbuds. Connecting is straightforward: select the model from the Bluetooth device list on your phone – or any compatible device, thanks to Multipoint support – and the earbuds quickly synchronize with the app. The main screen displays the charge level of each earbud individually, the case battery, and the currently active codec. This makes it immediately clear whether audio is streaming over LDAC or AAC – a detail that matters to audiophiles.
From there, you can choose where to start – whether following the setup guide (highly recommended), configuring noise cancellation, adjusting the equalizer, or testing how your voice will sound to the person on the other end of a call.
Regarding noise control, both ANC and transparency modes are highly flexible. The Noise Cancelling mode automatically adapts to surrounding noise, but you can also manually adjust the level using a vertical slider – helpful if you want to remain aware of your surroundings in a café or office.
The Ambient Sound mode allows external sounds to pass through naturally; adjusting the circular dial produces a very realistic effect. If you prefer purely passive listening without any processing, the Off mode disables all noise processing entirely – no filtering, no effects, just the raw audio.
The sound presets are also impressive. DIRECT delivers a completely clean, unprocessed signal. BASS+ and SUPER BASS+ boost low frequencies so you can physically feel the music, and the app’s visual graph clearly shows which frequencies are being enhanced. My personal favorite was the Dynamic preset. For true audiophiles – those likely to choose these earphones – there are also three customizable slots available in the app, allowing you to create and save your own sound profile.
The Multipoint feature is excellent. You can keep up to three devices connected simultaneously. I have my laptop, phone, and e-reader connected at the same time, and switching between them is seamless. For example, if I’m watching a video on my tablet and a call comes in on my phone, the earbuds instantly switch audio to the phone and then back afterward. Bluetooth 5.3 ensures everything runs smoothly, without lag or dropouts.
The interface is logical and straightforward: battery level, codec, ANC, transparency, and bass presets are all immediately accessible. There’s no need to navigate deep menus – everything feels intuitive. Whether you want to fine-tune the sound, test how the AI enhances voice, or quickly switch between three connected devices, the Audio Connect app effectively unlocks the full potential of the EAH-AZ100, making the earbuds highly practical for everyday use.

Microphones on the Technics EAH-AZ100
Most high-end TWS earbuds already include basic voice enhancement for calls, so the AZ100 isn’t unique in that regard. However, Technics goes further with a dedicated Voice Focus AI chip specifically for uplink voice processing. This works in conjunction with a six-MEMS-microphone array to analyze the speech spectral mask in real time, filtering out ambient noise and suppressing sounds that don’t resemble human voice.
In practice, this means that wind, traffic, and city noise are effectively filtered out, leaving only a clear, uncompressed voice – comparable to what you’d expect from a professional headset.
The biggest surprise, however, is the “reverse” functionality. The AZ100 not only isolates your voice for the listener but also attempts to enhance the audio coming from the person on the other end. If the caller is using an older smartphone or a low-quality microphone, the system analyzes the incoming audio, reduces noise, adjusts the frequency response, and makes their voice more intelligible.
It’s essentially an “AI call restoration”: instead of a muddled, noisy signal, you get much clearer speech. While it won’t turn a poor microphone into a studio-quality one, the improvement is immediately noticeable. Features like this are rarely seen even in much more expensive models.
Moments like these create a real sense of premium quality. The EAH-AZ100 doesn’t just focus on how others hear you – it also enhances how you hear them, even when the other party’s equipment is clearly outdated.

Noise Cancellation
The noise cancellation on the Technics EAH-AZ100 deserves its own section due to its quality. It features fully adaptive hybrid digital ANC, which doesn’t just generate a static anti-noise signal but continuously adjusts to the real environment. A six-MEMS-microphone array constantly scans the acoustic landscape and adjusts filtering in real time.
Outdoors or on the street, the effect is immediately noticeable: low-frequency hums from engines or ventilation systems are almost entirely eliminated, while the resulting quiet remains “soft,” without the pressure on the eardrums typical of poorly tuned ANC. This is a clear indication of well-calibrated phase alignment and properly implemented DSP processing.
Intelligent algorithms in the companion app play a key role. The earbuds don’t just indiscriminately cut all sound – they selectively filter based on the type of noise. In Transparency mode, the system preserves the natural character of mid and high frequencies. Even in challenging scenarios with impulsive noises – clicks, bangs, or sudden sounds – the ANC remains stable, without artifacts or disruption of the soundstage.
For listeners streaming music via LDAC with an extended frequency range up to 40 kHz, this level of noise cancellation is critical. It creates the “black background” on which micro-details, reverberation tails, and subtle textures in the upper register become clearly audible. This, in turn, helps define the signature, high-fidelity sound architecture that Technics aims for.

Sound of Technics EAH AZ100
The first track I tried on these earbuds was AURORA – Running With The Wolves (Live Session), and… I nearly spilled my coffee. This isn’t just sound – it feels like an intimate audio voyeurism. Every note has a tangible quality; it’s not merely heard, it’s felt. The detail is so extraordinary that the singer’s voice is dissected into micro-elements: every breath, every subtle inflection is audible, all delivered with such transparent air that the stage seems to expand beyond the confines of my room.
We’re talking about a 10 mm “magneto-fluid custom” driver. You might wonder what the magic is. Inside the driver gap, a specialized ferromagnetic fluid dampens unwanted diaphragm resonances without adding weight, allowing for an ultra-thin aluminum diaphragm. This is a technology borrowed from Technics’ $1,500 luxury monitors.
The result? In Woodkid – The Shore, the dynamic orchestral swells hit with full impact, right into the solar plexus, yet they remain refined, with a deliberate, almost aristocratic precision in every violin note.
Now, for my favorite part: the bass on the AZ100. It’s not the loose, boomy thump typical of mass-market earbuds. In Sevdaliza – Human, the low line hits with punch and precision, driving the track’s dark mood while remaining tight and controlled. There’s no unnecessary “weight” for its own sake – just pure energy and perfect control. Meanwhile, the highs shine smoothly, providing plenty of space and clarity for the mix to breathe.
To start, I highly recommend trying the DIRECT preset – why mess with an already perfect balance? If you want a bit more excitement, BASS+ adds punch, though it slightly compromises that pristine equilibrium. A small tip: enabling noise cancellation makes the bass feel even more alive. The AZ100 also supports a spatial soundstage via Dolby Atmos and Head Tracking, which is handled delicately. Honestly, I wouldn’t overuse it: the natural, “bare” sound of these drivers is so impressive that virtual enhancements are almost unnecessary.

Battery Life
The Technics EAH-AZ100 performs like a marathon runner, offering roughly 7.5 hours of continuous playback with ANC enabled.
With the charging case, total playback reaches about 25 hours, enough to cover several trips, work calls, and evening playlists. Considering the constant operation of the DSP, the six-microphone array, and AI algorithms that adjust phase, filtering, and spectral analysis in real time, this is a very respectable result for a premium segment product.
Touch controls are precise and reliable: gestures are consistently recognized without phantom touches or accidental repeats.
Track skipping, volume adjustments, and voice assistant activation all respond quickly, with no noticeable delay in the signal chain.

Experience using Technics EAH AZ100
During extended use, several key aspects become apparent that distinguish the EAH-AZ100 as a true tool rather than just another pair of TWS earbuds. Foremost among these is the stability of the Bluetooth stack.
Bluetooth 5.3, combined with three-device Multipoint support, performs exactly as intended: the laptop, smartphone, and tablet switch seamlessly between each other without dropouts, pauses, or unusual delays.
I also took note of the ear tips. The included silicone tips provide decent isolation, but switching to Comply foam tips noticeably changes the sound. Seal tightens, improving control over the low end. Sub-bass becomes denser and more articulated, without any smearing. As mentioned earlier, passive isolation combined with adaptive ANC creates that “black background” on which LDAC streaming reveals the full dynamic range and subtle recording details.
In daily use, the earbuds prove highly comfortable and ergonomic. The 5.9 g weight is well-balanced, so even after four hours of listening there’s no fatigue or urge to remove them. Auto-pause works accurately without false triggers, and the touch panels respond reliably, allowing near-intuitive control without looking at the screen. All the complex internal systems – Voice Focus AI, DSP, and magneto-fluid drivers – operate consistently in the background, providing a predictable and comfortable daily experience.

Conclusions
The Technics EAH-AZ100 strikes a rare balance between analytical detail and musicality. The magneto-fluid drivers and Voice Focus AI chip justify their premium price, delivering a professional-grade experience for listeners who are tired of mass-market plastic sound and seek a true High-Res TWS experience.
They perform best with a high-quality source, such as LDAC streaming, and benefit from attention to small details – like selecting the right foam tips for optimal seal and bass control. In a market where many focus on quantity of features, Technics emphasizes the quality of every diaphragm movement, creating a product that doesn’t just play a playlist but reveals the architecture and nuances of each track.
If you’re just looking for earbuds to have background music playing, go for AirPods. But if you want to hear the subtle color of the rosin on your favorite cellist’s bow, welcome to the big league.
