Technics Reference Class EAH-AZ100-K
Derived from Technics' reference-class TZ700 wired IEMs, the AZ100's 10mm magnetic fluid driver and LDAC support deliver distortion-free highs and deep bass with Hi-Res audio. Adaptive noise cancellation and Dolby Atmos head tracking create immersive, personalized soundscapes, while 10-hour battery life (28 with case) and a 15-minute quick charge for 90 minutes of playback keep you listening longer. Best suited for audiophiles and commuters prioritizing sound quality and adaptive ANC, though the IPX4 rating and weaker fitness score make it less ideal for intense workouts.

The 30-Second Version
The Technics AZ100 deliver the best sound we've heard from a pair of true wireless earbuds, with ANC and call quality that run circles around Sony and Bose. But you can't adjust volume with a tap, and your wallet will feel it.
Overview
The one thing you need to know: the Technics EAH-AZ100 are the new benchmark for true wireless earbuds. They combine reference-class sound, class-leading noise cancellation, and superb call quality into a package that's smaller and lighter than their already excellent predecessor. After weeks of listening, we're convinced these are the earbuds to beat right now—if you can stomach the price.
Performance
What surprised us most was just how natural and spacious the soundstage is. Those 10mm planar magnetic drivers pull out details we usually only hear on over-ear headphones. The ANC is eerily good, adjusting on the fly and blotting out everything from airplane drone to coffee shop chatter. And call quality? With six mics and a dedicated AI chip, your voice comes through crystal clear even in a wind tunnel. Our only wish: they don't get quite as loud as some competitors, so if you crave ear-shattering volume, you might be left wanting.
Pros & Cons
Pros
- Audiophile-grade sound with breathtaking detail and soundstage 99th
- Elite ANC that adapts seamlessly to your environment 97th
- Call quality that embarrasses most dedicated headsets 97th
- Lightweight, comfortable design with a generous 10-hour battery 97th
- Multipoint connection for three devices at once
Cons
- No way to adjust volume directly on the earbuds (come on, Technics!)
- Max volume could be higher for those who like it loud
- Premium price with no built-in tracker for lost buds
- Only IPX4, so not ideal for heavy workouts

Value & Pricing
At $248 to $340, these aren't cheap. But you're getting the best-sounding wireless earbuds money can buy, period. If you care about audio quality first and everything else second, the AZ100 are worth every penny. For everyone else, there are solid options at half the cost—but they won't make your music feel this alive.
vs Competition
The obvious rivals are the Sony WF-1000XM5 and Bose QuietComfort Ultra Earbuds. Sony's ANC is neck-and-neck, but the Technics pull ahead in sheer musicality and call clarity. Bose fights back with a more immersive spatial audio that some might prefer, but they can't match the AZ100's refined, reference tuning. The Sennheiser Momentum True Wireless 4 is closer in sound philosophy, but its ANC and mic quality fall short. If you want one pair to rule them all for music and calls, the Technics are it.

Common Questions
Q: Can I adjust volume directly on the earbuds?
Nope, and that's the most frustrating thing about these. You'll need to use your phone or voice assistant. For earbuds this smart, it's a weird miss.
Q: How does the noise cancelling stack up?
It's elite. Right up there with the Sony XM5, adapting automatically to your surroundings. In our testing, it shut out airplane noise almost completely.
Q: Do they have a find-my-earbuds feature?
No built-in locator, so don't misplace them. If you're the type who loses small things, consider the AirPods Pro with Find My.
Who Should Skip This
If you sweat buckets at the gym, look elsewhere—the IPX4 rating is just splash protection and the fit isn't lockdown secure for burpees. Grab the Jabra Elite 8 Active for workouts. And if you're budget-conscious, the EarFun Air Pro 4+ deliver surprisingly great sound for under $100, albeit without the audiophile magic.
Verdict
These are the earbuds for anyone who refuses to compromise on sound. The ANC and call quality are just icing on an already delicious cake. Yes, the missing volume control is annoying, and they won't rattle your skull at max volume, but as a total package, the Technics EAH-AZ100 are the best true wireless earbuds we've tested. Highly recommended.
