Technics EAH-AZ100 Review: Reference-Class Wireless Earbuds with Dolby Atmos Precision

Wireless earbuds have come a long way, but only a few brands truly treat them as serious audio equipment. Technics is one of those brands. With the Technics Reference Class Hi-Fi Wireless Earbuds (EAH-AZ100-N), the company brings decades of high-end audio engineering into a compact, premium true wireless design.

Featuring Dolby Atmos with head tracking, adaptive noise cancelling, three-device multipoint, and a refined ergonomic fit, the AZ100 aims to be more than just another premium earbud. It positions itself as a reference-grade listening tool for people who care deeply about sound quality, comfort, and long-term usability.

In this detailed review, we’ll break down real-world performance, sound quality, features, battery life, and whether the Technics EAH-AZ100 is worth the investment.

Quick Overview: Technics EAH-AZ100 at a Glance

Sound: Reference-grade tuning with deep bass and precise mids

Design and Build Quality

Technics keeps things understated and elegant with the Champagne finish, which looks premium without being flashy. The earbuds feature a brushed metal faceplate with the Technics logo subtly engraved, giving them a high-end Hi-Fi aesthetic rather than a lifestyle gadget vibe.

The charging case follows the same design language. It feels solid in hand, with smooth edges and a satisfying lid action. This is the kind of build quality you expect from a brand with a strong heritage in professional audio equipment.

Despite the premium materials, the earbuds remain lightweight and well balanced, which helps with comfort during longer listening sessions.

Improved Fit and All-Day Comfort

One of the biggest improvements in the AZ100 is the refined ergonomic shape. Technics redesigned the housing to sit more naturally in the ear, reducing pressure points and improving stability.

In real-world use, the earbuds stay secure during:

Walking and commuting
Light workouts
Long desk sessions
Extended listening sessions over several hours

Multiple ear tip sizes are included, allowing you to fine-tune the seal. A proper seal is crucial not only for comfort but also for bass performance and noise cancellation. If fit has been an issue with other premium earbuds, the AZ100 is noticeably more forgiving.

Sound Quality: Reference-Class Performance

This is where the Technics EAH-AZ100 truly stands out.

Bass

The bass is deep, controlled, and textured. It delivers impact without overpowering the mix. Sub-bass presence is excellent, especially with electronic and cinematic tracks, but it never feels bloated.

Midrange

Vocals are natural and forward without sounding artificial. Acoustic instruments, guitars, and piano retain their original character, which is critical for jazz, classical, and vocal-heavy music.

Treble

High frequencies are clean and detailed, with no harshness. Even at higher volumes, the treble remains smooth, making long listening sessions fatigue-free.

Overall, the sound signature leans toward balanced and accurate, rather than exaggerated. Audiophiles who prefer clarity over hype will appreciate this tuning.

Dolby Atmos with Head Tracking

The inclusion of Dolby Atmos with head tracking elevates the AZ100 beyond standard stereo earbuds. When supported content is played, the soundstage becomes wider and more immersive.

Head tracking dynamically adjusts the audio field as you move your head, keeping vocals and instruments anchored in place. This is especially noticeable when watching movies or listening to live recordings.

While not every app supports Dolby Atmos, when it works, the effect feels natural rather than gimmicky.

Adaptive Noise Cancelling Performance

The adaptive noise cancelling system automatically adjusts based on your surroundings. Instead of applying a constant level of cancellation, it reacts in real time to environmental noise.

In daily use, this means:

Strong reduction of traffic and engine noise
Effective suppression of office chatter
Minimal pressure or “ear fatigue”

Transparency mode is equally impressive, allowing natural ambient sound when needed. Voices sound clear, which makes quick conversations possible without removing the earbuds.

Three-Device Multipoint Connectivity

Unlike many competitors that limit multipoint to two devices, the AZ100 supports simultaneous connection to three devices.

This is extremely useful if you regularly switch between:

Smartphone
Laptop or desktop
Tablet or smart TV

The transition between devices is seamless, with no noticeable audio dropouts. For productivity and multitasking, this feature alone can justify the price.

Battery Life and Charging

Battery performance is strong for a feature-rich earbud.

Up to 10 hours on a single charge (with ANC off)
Additional charges from the case extend total listening time significantly
Wireless charging adds everyday convenience

Even with noise cancelling enabled, battery life remains competitive. The earbuds are reliable for full workdays, long flights, or extended listening sessions without constant charging anxiety.

Controls and App Experience

Touch controls are responsive and customizable through the Technics app. You can assign functions like:

Volume control
ANC and transparency switching
Playback and call management

The companion app also allows EQ adjustments, firmware updates, and spatial audio settings. The interface is clean and functional, focusing on usability rather than unnecessary animations.

Call Quality and Microphones

Call quality is clear and consistent. The multi-mic setup does a solid job isolating your voice while reducing background noise.

In both indoor and outdoor environments, voices remain natural and intelligible. This makes the AZ100 suitable not only for music but also for work calls and video meetings.

Who Should Buy the Technics EAH-AZ100?

These earbuds are ideal for:

Audiophiles who want accurate, reference-style tuning
Professionals who need stable multipoint connectivity
Frequent travelers who value effective noise cancelling
Users who care about comfort during long sessions

If you’re more focused on heavy bass or fitness-focused features, there may be better options. But for sound quality and refinement, the AZ100 stands among the best.

Final Verdict: Is the Technics AZ100 Worth It?

The Technics EAH-AZ100-N delivers exactly what its “Reference Class” label promises. Exceptional sound quality, thoughtful features, and premium build quality come together in a polished, reliable package.

It doesn’t chase trends or exaggerate sound. Instead, it focuses on balance, realism, and usability. For listeners who take audio seriously and want wireless convenience without compromise, this is an easy recommendation.
