Overview
The Technics EAH-AZ100 is a premium true wireless earbud that caters to serious listeners. Known for its rich audio signature, clean design, and long battery life, the AZ100 strikes a nice balance between high-end audio performance and daily usability. It delivers a clear, dynamic soundstage with customizable EQ and hybrid noise canceling.
In this review, we’ll break down our experience with the Technics EAH-AZ100 across design, fit, sound quality, and long-term comfort. We’ll also explain how using memory foam ear tips—like those from Comply—can elevate the already great experience of these buds.
Design & Build Quality
Technics leans into a refined, no-nonsense aesthetic. The AZ100 buds are sleek and matte with a subtle metallic faceplate that gives off a modern, polished vibe without trying too hard. The buds feel premium in the hand, with a secure but lightweight construction.
The charging case is relatively slim, pocket-friendly, and features USB-C and wireless charging—two welcome conveniences at this tier. The buds are IPX4-rated for sweat and water resistance, making them suitable for light workouts and travel.
Fit & Comfort
Out of the box, the AZ100 includes silicone tips in several sizes. The buds are on the slightly larger side, but the ergonomic shape helps them sit comfortably in most ears. We tested the fit across a variety of activities—sitting at a desk, commuting, and light movement—and found them to stay in place fairly well.
That said, switching to memory foam ear tips dramatically improves the experience . Foam molds to the shape of your ear canal, filling gaps and creating a more secure, personalized seal. With foam tips, we experienced better grip, enhanced noise isolation, and significantly less ear fatigue during extended listening sessions.
This is especially noticeable when wearing the AZ100 for long stretches—whether you're deep in focus at your desk or relaxing on a flight.
Sound Quality
Technics has a long-standing reputation in the audio world, and it shows here. The AZ100 is tuned for balance and clarity, offering a wide soundstage and excellent detail across lows, mids, and highs. Bass is full but not boomy, mids are smooth, and highs are crisp without harshness.
The app allows for EQ adjustments if you want to tailor the sound further, and the dual hybrid noise canceling is effective enough for most everyday situations without heavily coloring the audio.
We noticed that foam tips help preserve that clarity while enhancing the passive isolation, letting you keep ANC on lower levels (or even off) while still blocking out a good amount of external noise. It keeps the focus on the music—not the environment.
Noise Isolation & Use in Real Life
With the stock silicone tips, isolation is decent, but still lets in ambient sound depending on your ear shape. Swapping to foam tips created a much better passive seal, which worked wonders on airplanes, coffee shops, and noisy office settings.
What stood out most is the natural isolation foam provides—it reduces the need for aggressive ANC levels, making listening more comfortable and less fatiguing over time. You also get fewer audio leaks, which is ideal for commuting or shared spaces.
Battery Life & Controls
The AZ100 boasts up to 7.5 hours of playback with ANC on, and up to 25 hours total with the charging case. That’s plenty for long days and overnight trips. The touch controls are customizable and responsive, and we had no trouble navigating playback, volume, or activating voice assistants.
Pairing is snappy and stable, thanks to Bluetooth 5.3 and multipoint support. Whether on iOS or Android, the experience was smooth.
Who It’s For
If you're an audiophile who doesn’t want to compromise on portability, the Technics EAH-AZ100 is a smart pick. It's ideal for users who care about balanced sound, modern features, and comfort across long sessions.
And if you’re the kind of person who wears your earbuds for hours at a time—whether for work, travel, or deep listening— upgrading to memory foam tips is absolutely worth it .
🔍 What Could Improve in Future Versions
The AZ100s are strong performers, but a few tweaks could elevate the experience for their next gen device:
A slimmer design for smaller ears
More tip variety included in the box
Better wind noise reduction outdoors
Slightly improved call clarity in noisy settings
None of these are deal-breakers, but they’re areas Technics could refine in a next-gen release.
🧠Final Thoughts
The Technics EAH-AZ100 nails the essentials: premium audio, excellent build quality, strong ANC, and comfort. But paired with high-quality memory foam tips, they become even more impressive—offering a more stable fit, better noise isolation, and a boost in day-to-day usability.
We recommend the AZ100 for anyone who wants studio-grade clarity in a lifestyle-ready earbud—and if you’re chasing the best possible fit and sound isolation, foam tips make all the difference .
