Technics EAH‑AZ100E‑K: Best Noise‑Cancelling Wireless Earbuds of 2025?

 From the moment you slide the Technics EAH‑AZ100E‑K Wireless Earbuds into your ears, you get the sense that these are no ordinary true wireless buds. Technics has a long heritage in audio, and these earbuds show that the brand understands what discerning listeners want: a supremely comfortable fit, robust noise cancelling, seamless connectivity and a sound signature that honours detail and musicality. Having spent several weeks with them, here’s my honest take on what they do brilliantly — and where they could do a little better.

First impressions and design
Out of the box, the EAH‑AZ100E‑K earbuds impress with a sleek, matte‑black finish that feels understated yet premium. The charging case is compact and pocket‑friendly, with a softly rounded shape that slips easily into a jeans or jacket pocket. The earbuds themselves carry a discreet Technics logo on the outer surface, finished in a subtle glossy accent that catches the light. At around 5.5 grams each, they’re light enough that you quickly forget they’re there — an aspect that plays into the exceptional comfort these buds offer over extended listening sessions.

Comfort and fit
Technics include a variety of silicone tips in different sizes, and swapping them out takes only a moment. Once you’ve found the sweet spot, the earbuds seal beautifully, creating a snug fit without any pinching or pressure points. I wore them on my daily three‑mile runs, during long train journeys, and even for video calls, and never felt the urge to fidget or readjust. They’re so comfortable that you might even catch yourself rummaging through playlists just to keep them in!

Build quality
Far from feeling flimsy, the AZ100E‑K pair feel solid and well‑engineered. The hinge on the charging case is reassuringly firm, yet smooth to open and close. The earbuds have an IPX4 splash‑resistance rating, so a sudden shower or a bit of perspiration won’t send you scrambling for a towel. While they’re not fully waterproof, I tested them during a downpour and they shrugged it off — although I’d still avoid submerging them or wearing them in the pool.

Sound signature
When it comes to audio, these Technics earbuds are a joy. They strike a fine balance between warmth and clarity: bass is full‑bodied without overpowering, mids are expressive, and treble sparkles just enough to give vocals and acoustic instruments a lifelike edge. Whether you’re savouring a classical piano sonata, head‑banging to heavy metal, or tuning into your favourite podcast, the sound remains engaging and accurate.

There’s also a sense of spaciousness that I didn’t expect from such small drivers. Tracks feel well‑paced, with each instrument having room to breathe. You’re not getting an overly hyped “V‑shape” tuning; rather, you’re treated to a more natural, balanced presentation. Audiophiles might wish for a touch more sub‑bass authority, but for most listeners, the lows hit hard enough to satisfy without muddying the mix.

Active Noise Cancelling (ANC)
Technics’ noise cancelling is impressive. In “Full ANC” mode, the earbuds effectively diminish the drone of aeroplane engines, the rumble of underground trains and the murmur of office chatter. It’s not quite at the level of the very best on the market, but it’s comfortably ahead of what you get from most mid‑range offerings. There’s also an “Ambient Sound” mode that lets you bring in some outside noise when you need situational awareness — for example, when you’re crossing a busy street or chatting with colleagues without removing an earbud. A simple tap‑and‑hold gesture toggles between modes, and I found the transitions to be smooth and immediate.

Multipoint Bluetooth connectivity
One standout feature here is multipoint Bluetooth. You can pair the earbuds with two devices simultaneously — say, your phone and laptop — and they’ll switch between sources intelligently. I tested this by streaming music from my phone, then taking a Zoom call on my laptop. The earbuds paused the music and picked up the call seamlessly, then resumed playback once the meeting ended. There’s no fumbling with unpairing or manual switching; it simply works, and that convenience is worth its weight in gold for anyone juggling multiple devices.

Voice Focus AI for calls
Technics have introduced Voice Focus AI, a system designed to enhance the clarity of the person speaking into the mic while suppressing background noise. In practice, this means your calls come through crisp and clear, even in noisy environments. I had a friend call me from a bustling café, and they reported I sounded as though I were in a quiet room. Conversely, when I called them from my kitchen while they were walking in a park, they heard almost no wind noise or passing traffic. It’s a subtle but highly effective feature that elevates these buds above many rivals in the true wireless category.

Battery life and charging
You’re looking at around six hours of playback with noise cancelling enabled, and up to seven hours with ANC turned off. The charging case adds another 18–20 hours, so you’ll comfortably get through two or three full days of commuting and calls before needing to recharge. A 15‑minute quick charge gives you roughly 70 minutes of listening — ideal if you’ve forgotten to top up but need a rapid boost. The case itself charges via USB‑C, and there’s wireless charging support too, which is always a welcome convenience.

User interface and app support
Technics provide a companion app for iOS and Android that gives you control over sound profiles, noise cancelling strength, tap‑control customisation and firmware updates. The interface is clean and intuitive, albeit not quite as feature‑packed as some rivals. You get an equaliser with a handful of presets, plus the option to tweak bass, mids and treble manually. There’s also a “Find My Earbuds” function that beeps the buds to help locate them when they inevitably go missing under the sofa.

Price and value
At the time of writing, the EAH‑AZ100E‑K sit in the mid‑to‑upper tier of the true wireless market. They’re not bargain‑basement cheap, but you’re paying for top‑notch ANC, comfortable fit, solid battery life and that multipoint connectivity with Voice Focus AI. Compared with cheaper buds that cut corners on noise cancelling or sound quality, these feel like a worthwhile investment. And while they’re not quite as affordable as the entry‑level options from lesser‑known brands, they deliver a level of polish and reliability that more than justifies the premium.

What could be better?
No product is perfect. The noise cancelling, while excellent, isn’t quite at Sony WF‑1000XM level, and audiophile purists might hanker after a more granular equaliser within the app. The touch controls can be overly sensitive at times, registering accidental taps when you adjust your hair or fidget during calls. Lastly, the case, while neat, lacks a bit of heft, so it doesn’t feel as rugged as some of the chunkier offerings out there.

Final verdict
All told, the Technics EAH‑AZ100E‑K Wireless Earbuds are a delight to use. They marry superb comfort and build quality with a lively, balanced sound signature, effective noise cancelling and truly seamless multipoint Bluetooth switching. The addition of Voice Focus AI elevates call quality, making them ideal for remote workers or frequent travellers. If you’re after a premium pair of buds that can handle music, podcasts and calls with equal aplomb, and you don’t mind paying a little extra for that all‑round polish, these are among the best you can buy in 2025. Highly recommended for anyone who values both form and function in their audio gear.
