Technics EAH-AZ100 Review (2026): Detail Meets Features

This Technics EAH-AZ100 review looks at a pair of true wireless earbuds aimed at people who care about how music sounds but don't want to give up modern conveniences. It pairs a 10 mm (3/8 in) magnetic fluid driver with adaptive noise cancelling, six microphones for calls, multipoint Bluetooth and a Qi wireless charging case. It sits in the mid-range part of the market. It is built for sound-focused listeners who still want strong ANC and a full feature set.

This article is based on the manufacturer's specifications and on what independent expert reviews report. It is not based on our own hands-on testing.

What the experts think

The EAH-AZ100 has been received very well. It averages 9.8/10 across 4 expert reviews. Trusted Reviews, What Hi-Fi? and T3 each give it 5/5, and Gizmodo scores it 4.5/5. It's worth seeing what reviewers praise and where the criticisms sit. Both are covered below.

Technics EAH-AZ100 review: design and fit

The earbuds use a concha-fit design that Technics describes as smaller and lighter. Each bud weighs approx. 5.9 g (0.21 oz), and the charging case is approx. 42 g (1.5 oz). Five ear tip sizes are included, which gives you a reasonable chance of finding a good seal. A good seal matters for both bass response and noise cancelling.

The buds come in five colours: Silver, Black, Champagne Gold, Midnight Blue and Moonlight Lilac. Reviewers describe the styling as plain, and a common criticism is that the case scratches easily. If you like earbuds that make a statement, these are understated. If you'd rather they blend in, that may suit you.

Fit is the most important thing to check before you buy. Reviewers note that the deeper in-ear fit can feel uncomfortable for some people. Comfort is personal, and a design that sits further in the ear suits some listeners better than others. If you have found deep-fit earbuds irritating in the past, treat this as a real consideration and not a footnote.

The earbuds carry an IPX4 Equivalent water resistance rating. That covers the earbuds only, not the case. It is enough to be reassuring for sweat and light splashes, but these are not built for submersion.

Sound quality

The driver is the centrepiece. Technics' Magnetic Fluid Driver is designed for low-distortion, high-resolution sound. The stated frequency response is 20 Hz - 40 kHz, and with LDAC the spec runs to 96 kHz/990 kbps.

Reviewers consistently praise the sound as detailed, clear and well balanced, with punchy bass. That fits the product's positioning: this is a pair of earbuds sold on how they sound, with the features added around that.

Codec support is broad: SBC, AAC, LDAC and LC3. LDAC is the one that matters most for listeners who want higher-resolution streaming from a compatible device. There's a trade-off, covered in the battery section.

Spatial audio

The earbuds support spatial audio optimised for Dolby Atmos, with Dolby Head Tracking. Reviewers list head tracking among the standout features. It's most relevant if you watch films or play Atmos content on your phone or tablet, and less so if you mostly stream stereo music.

Noise cancelling and calls

The noise cancelling is described as Full Adaptive Digital Hybrid. The adaptive system adjusts to your surroundings in real time.

Reviewers say the ANC is strong, especially against low-frequency rumble such as engine noise. That makes the buds a sensible choice for commuting and travel. A common criticism is that it is good but not class-leading, with Bose noted as better in some mid frequencies. If the most powerful noise cancelling available is your top priority, that is worth bearing in mind. If you want strong ANC alongside sound quality and features, the EAH-AZ100 looks well suited.

Calls are another strength. Six microphones work with Voice Focus AI to deliver clearer calls, and reviewers rate call quality as very good. If you take a lot of calls on the move, that counts for more than it might seem.

Battery life and charging

On AAC with noise cancelling on, the earbuds last approx. 10.0 hours. With noise cancelling off, that rises to approx. 12.0 hours. With the case included, the total reaches approx. 28 hours with ANC on.

If you stream over LDAC, the figure drops. With LDAC and ANC on, the earbuds are rated at approx. 7.0 hours. Reviewers flag this as a drawback. You gain higher-resolution streaming and lose some endurance, so it's a choice you make depending on the day.

The case supports USB-C and Qi wireless charging, though a Qi charger is sold separately. There is also a 15-minute quick charge that provides 90 minutes of playback. That is handy if you notice the battery is low just before leaving the house.

Connectivity and multipoint

The earbuds use Bluetooth 5.3 with an operating distance of up to 10 m (33 ft). Multipoint connects to up to 3 devices at a time, with seamless switching. That helps if you move between a phone, a laptop and a tablet during the day.

There is one caveat to be aware of. LDAC playback is not available when three devices are connected. If you want the best audio quality from LDAC, you'll need to use fewer simultaneous connections. Reviewers list this as a limitation.

Who should buy the EAH-AZ100

This is a good match if you:

• Care about detailed, balanced sound and want punchy bass
• Want strong noise cancelling for commuting or travel
• Take a lot of calls and want good microphone performance
• Switch between several devices and want three-device multipoint
• Value wireless charging and LDAC support

Who should skip it

Look elsewhere if you:

• Have found deeper in-ear fits uncomfortable before
• Want the most powerful noise cancelling available, as reviewers say it is good but not class-leading
• Plan to use LDAC all the time and need long battery life or three simultaneous connections
• Want eye-catching design, since the styling is plain and the case scratches easily

How it fits in its category

The EAH-AZ100 combines detailed sound, strong noise cancelling and a full feature set. Reviewers' reservations concern the deeper fit, noise cancelling that is good but not class-leading, and the LDAC trade-offs. If you want a broader view of the category before you decide, compare it against other premium noise-cancelling earbuds on the features that matter most to you: ANC strength, codec support, battery life and comfort.

Verdict

The EAH-AZ100 earns its high expert scores through a combination of refined, detailed sound, strong low-frequency noise cancelling, very good call quality and a feature set that includes multipoint, Dolby head tracking, LDAC and wireless charging. The weak points are specific and easy to check. They are the deeper fit, the plain looks and scratch-prone case, and the LDAC compromises on battery and multipoint. If the fit works for you and you listen for the sound first, this is a very strong choice.
