The Magnetic Fluid Driver Behind The AZ100's Sound

The AZ100 uses a 10mm Magnetic Fluid Driver based on technology originally developed for Technics' EAH-TZ700 wired in-ear monitors. The interesting part isn't simply the driver diameter, but how Technics controls its movement.

According to Technics, magnetic fluid helps center the voice coil and stabilize the diaphragm, reducing unwanted movement that can produce distortion. The design also allows for a thinner diaphragm edge, which is intended to improve bass reproduction and transient response.

Implementing this technology in a wireless earbud is considerably more complicated than in a conventional wired IEM. Technics has to accommodate batteries, microphones, Bluetooth electronics, and noise-cancelling components within the same limited housing.

That engineering is interesting, but it doesn't automatically tell us how the AZ100 sounds. For me, the most convincing results were its clarity, stereo imaging, and how well it handled additional bass without noticeably obscuring vocals.

The Bass Was The First Thing That Caught My Attention

My first impression of the AZ100 was its excellent clarity and strong volume output. The default tuning wasn't particularly lacking in low frequencies, but it didn't deliver the bass impact I was looking for.

That changed when I selected Super Bass+ in the Technics Audio Connect app.

The difference wasn't subtle. Music gained considerably more weight and low-frequency impact, making the AZ100 feel much more energetic without requiring me to raise the volume.

The app's equalizer display illustrates what the preset is doing, with a substantial boost in the lower frequencies while the midrange and treble remain comparatively unchanged. More importantly, I could hear the effect without feeling that the rest of the music was being pushed into the background.

I've used bass-heavy earbuds where the lower frequencies become overwhelming, making vocals and instruments difficult to distinguish. Even with Super Bass+ enabled, the AZ100 maintained the separation and clarity that originally impressed me.

I wouldn't necessarily use Super Bass+ for every recording, but it's the setting that made me appreciate the AZ100's bass capabilities. Without experimenting with the equalizer, I might have overlooked one of the earbuds' most enjoyable characteristics.

An Impressive Soundstage For Such Small Earbuds

What surprised me even more than the bass was the AZ100's stereo imaging. With ordinary music playback, I could clearly distinguish instruments positioned on the left and right sides of a recording.

At times, the presentation felt surprisingly open, almost as though certain instruments were playing somewhere in the room rather than directly inside my ears. That impression remained even with active noise cancellation enabled.

The important distinction is that the AZ100 doesn't simply make everything sound artificially distant. Individual instruments retain recognizable positions, which helps prevent busier recordings from becoming a wall of sound.

I found myself paying more attention to where instruments were placed, rather than merely following the main melody or vocals. For a pair of compact true wireless earbuds, that sense of separation made listening considerably more engaging.

The Technics App Became One Of My Favorite Features

I usually expect a companion app to handle basic setup, firmware updates, and a few adjustments before I largely forget about it. The Technics Audio Connect app became something I used regularly, and that wasn't simply because it offered a long list of settings.

The home screen provides separate battery readings for the left and right earbuds and the charging case. From there, I could access noise cancellation, sound enhancement, and microphone settings without navigating through several layers of menus.

Technics also includes a usage guide that introduces the earbuds' functions and explains how to get started. I appreciated this because the AZ100 has enough features that a less organized app could easily become confusing.

There is a good amount of customization available, including touch controls, noise cancellation behavior, and sound profiles. Yet the interface remained responsive and straightforward throughout my testing.

The app's biggest advantage is that its settings feel connected to how I actually use the earbuds. I could change the sound, manage surrounding noise, or check the microphones without feeling as though I was digging through a technical menu.

EQ Presets Helped Me Find The Sound I Wanted

The equalizer is a particularly good example of why I enjoyed using the Technics Audio Connect app. Technics provides six EQ presets along with three slots for custom sound profiles, giving listeners considerably more flexibility than a simple bass and treble adjustment.

What stood out to me was how noticeably different the presets sounded. With some earbuds, changing between sound profiles produces such a minor difference that I eventually stop bothering with them.

That wasn't the case here.

I found myself switching presets depending on the music because each offered a different balance worth considering. Certain recordings benefited from a stronger low end, while others sounded more natural with a less pronounced bass response.

This made it possible to find a sound I genuinely preferred rather than settling for the factory tuning. The presets weren't simply there to make the feature list longer; they made a meaningful difference to my listening experience.

Noise Cancellation Doesn't Quite Match Apple Or Bose

The AZ100 uses Full Adaptive Digital Hybrid ANC, which automatically adjusts noise cancellation according to the surrounding environment and how the earbuds fit. The Audio Connect app also allows manual adjustment when adaptive optimization is disabled.

Switching between Noise Cancelling and Ambient Sound modes produced an obvious difference during my testing. With ANC enabled, surrounding noise became less prominent, allowing me to concentrate more easily on the music.

However, some nearby sounds remained audible, even with noise cancellation active. The AZ100 reduced distractions rather than creating complete silence, which is an important distinction for anyone expecting total isolation.

One characteristic I particularly appreciated was the consistency of the music itself. I repeatedly switched between Ambient Sound and ANC, but couldn't identify a meaningful change in the sound signature.

That's important because I don't want to lose the tonal balance I've selected simply because I need to hear someone speaking or reduce surrounding noise. The AZ100 allowed me to change listening modes without feeling the need to adjust the equalizer afterward.

Voice Focus AI Is Genuinely Useful In Noisy Environments

The AZ100 uses three microphones in each earbud, combined with AI processing, to distinguish speech from surrounding noise during calls. Unlike systems that focus only on the wearer's microphone, Technics' Voice Focus AI also offers noise reduction for incoming audio.

I tested the microphones in a noisy environment, and my colleague on the other end of the call could hear me loud and clear despite the background noise. That gave me confidence in using the AZ100 for work calls when I wasn't somewhere particularly quiet.

The incoming noise reduction is an interesting addition, although it works differently from the outgoing microphone processing. According to Technics' instructions, suppressing noise around the other caller must be activated during the call and switches off again when the conversation ends.

That means the feature isn't entirely automatic, but I appreciate having the option when speaking with someone in a noisy environment. The app also includes a Voice Focus AI Test function that plays back a recording of your voice, allowing you to hear how the microphone processing affects it.

I didn't perform a controlled comparison against competing earbuds, so I wouldn't claim that the AZ100 has the best microphones in its class. What I can say is that the person I called had no trouble hearing me in conditions where background noise could have been a problem.

The Fit Is Secure Without Becoming Uncomfortable

Many true wireless earbuds include three sizes of silicone tips, but Technics supplies five with the AZ100: XS, S, M, ML, and L. The additional sizes allowed me to find a more precise fit, which is particularly important for earbuds that rely on a proper seal for both sound quality and noise cancellation.

The AZ100 also weighs just 5.9g per earbud, compared with approximately 7g for the preceding AZ80. That's a reduction of 1.1g per side, or roughly 16%, without sacrificing the secure fit I experienced.

The design reminds me of traditional in-ear monitors. After inserting the earbuds, a slight twist allows the silicone tips to seal inside the ear canal while the outer housing follows the natural contours of my ear.

This effectively locks the earbuds into position without relying entirely on pressure from the silicone tips. I didn't find myself constantly pushing them back into place or adjusting their position during normal use.

Despite that secure fit, I experienced no noticeable discomfort or fatigue during extended listening sessions. For earbuds intended to be worn for several hours at a time, I think that combination of comfort and stability matters more than simply making them as small as possible.

The Charging Case Is Small, But It Doesn't Feel Cheap

The AZ100's charging case measures approximately 69 × 36 × 27mm and weighs around 42g. It's compact enough to carry comfortably in a pocket, and its relatively small size makes the earbuds convenient to take everywhere.

What I liked was that the case still felt solid despite its compact construction. The cast-metal lid and housing gave me a reassuring impression of quality, rather than the lightweight, hollow feel I've encountered with some other charging cases.

Technics supports both USB-C and Qi wireless charging. The company rates a full case charge at approximately 2.5 hours over USB and 3.5 hours with a compatible wireless charger.

For me, the more useful specification is the fast charging capability: Technics claims that 15 minutes of charging can provide approximately 90 minutes of playback using AAC with ANC enabled.

I didn't independently time that charging result, but it's a useful provision for anyone who forgets to charge their earbuds before leaving home.

Bluetooth Connection Is Quick, But Multipoint Is Less Convincing

Bluetooth connectivity was excellent when I used the AZ100 with a single device. After removing the earbuds from their case, I generally heard the startup chime and had a working connection within approximately three seconds.

The AZ100 officially supports three-device multipoint connectivity, although I tested it with two devices connected simultaneously. Both could remain connected, but that didn't mean audio playback moved between them immediately.

When I stopped music on one device and started playing something on the second, the audio took roughly 10 seconds to switch over. The delay was consistent enough to become noticeable during normal use.

This is where I think it's important to distinguish between supporting multiple connections and making those connections convenient. Technics offers the ability to maintain several Bluetooth links, but in my setup, handing playback from one device to another wasn't particularly quick.

For someone who primarily listens from a single phone or computer, the AZ100 works very well. If you regularly move between a laptop and smartphone throughout the working day, however, the delay becomes a more significant inconvenience.

The Touch Controls Could Be A Little Faster

The AZ100's touch controls handled playback and listening-mode adjustments reliably during my testing. I also appreciate that Technics allows users to customize their functions through the companion app.

However, there was a slight delay between touching an earbud and the corresponding action taking place. It wasn't a major problem, but I occasionally found myself waiting for confirmation that the command had registered.

Given how responsive the Audio Connect app feels, I'd like to see the touch controls respond with the same immediacy. It's a small detail, but one that becomes more noticeable with repeated use.

Battery Life Is Strong, But The Codec Makes A Difference

Technics advertises up to 10 hours of continuous playback with AAC and ANC enabled, increasing to 28 hours with the charging case. Those figures place the AZ100 comfortably within the range I'd expect from premium wireless earbuds.

However, battery life changes significantly depending on the Bluetooth codec.

With LDAC and ANC enabled, Technics rates the earbuds for approximately seven hours, or 18 hours including the charging case. That's three hours less listening time per charge than the AAC specification, an important tradeoff for anyone intending to use LDAC regularly.

Independent testing offers another reference point. SoundGuys measured 10 hours and 40 minutes of playback in a standardized test using SBC with ANC enabled and music peaking at 75dB SPL. That is an external laboratory result, not a measurement from my own testing.

In everyday use, I estimated somewhere between five and ten hours of playback with ANC enabled, depending on usage. I didn't conduct a controlled battery rundown, but I also didn't encounter unusually rapid battery drain.

Ultimately, battery life wasn't something I regularly worried about. However, the difference between AAC and LDAC is worth understanding because the highest-quality codec setting doesn't necessarily deliver the longest listening time.

Final Verdict

The Technics EAH-AZ100 has several features that look impressive on paper, but its strongest quality became clear when I started listening to music. The soundstage is unusually spacious for such small earbuds, instrument positioning is easy to distinguish, and the sound remains clear even when Super Bass+ adds considerably more weight to the low end.

I wouldn't describe the default tuning as particularly exciting in the bass department, at least for my preferences. However, the Audio Connect app gives me the flexibility to change that without making the rest of the music sound muddy, and the six EQ presets offer enough variety that I found myself switching between them regularly.

The hardware also gets several important things right. Each earbud weighs just 5.9g, the five included tip sizes helped me find a secure fit, and I experienced no noticeable discomfort during extended sessions. Voice Focus AI also proved useful when my colleague could hear me clearly during a call in a noisy environment.

There are compromises, particularly with connectivity. Reconnecting to one device took around three seconds, but moving audio between two connected devices took roughly 10 seconds, which is a substantial difference in convenience. The touch controls could also be faster, and ANC reduced surrounding noise without completely eliminating nearby sounds.

At its $299.99 launch price, I think the AZ100 makes the strongest case for listeners who value sound quality and customization over effortless switching between multiple devices. Someone who primarily listens from one source will encounter fewer of the inconveniences I experienced.

What ultimately wins me over is that the AZ100 gives me a sound I enjoy and enough control to adapt it to different music. It isn't perfect, but its combination of excellent clarity, spacious stereo imaging, comfortable fit, and a genuinely useful companion app makes it a pair of earbuds I would happily recommend.
