メナHey, it’s Mena (@menachite), a hybrid engineer who handles both mechanical and electrical work. This time I lined up the entire current Technics noise-cancelling true wireless earbud lineup and compared them head to head.
Technics currently sells four NC earbuds, from the entry-level EAH-AZ40M2 up to the flagship EAH-AZ100, and it’s not always obvious which one to pick when they’re all from the same brand. Short version: as the price climbs, NC performance, battery life, and driver generation all step up together, and the real decision point is whether you value call quality and multipoint convenience or flagship-level sound. More on why below.
We compared the EAH-AZ40M2, EAH-AZ60M2, EAH-AZ80, and EAH-AZ100 across NC performance, fit, battery life, and codec support. Seeing what changes at each price tier makes it a lot easier to judge how much you actually need to spend for your use case.
Note on scope: this article covers the current Technics lineup only, one brand top to bottom. If you want a cross-brand comparison against Sony, Anker Soundcore, and final, check out our separate cross-brand comparison article instead.
At a Glance: Which One Should You Pick?
Short version up front: if you want to try Technics-grade NC without spending much, go with the EAH-AZ40M2. If 3-device multipoint and call quality matter most, the EAH-AZ60M2 is the safe pick. Want a balance of sound quality and value? The EAH-AZ80. Not willing to compromise on NC or sound at all? The EAH-AZ100.
| Model | Position | NC battery life | Codecs | Best for |
|---|---|---|---|---|
| EAH-AZ40M2 | Entry | 5.5h (18h total) | SBC/AAC/LDAC | Trying Technics-grade NC on a budget |
| EAH-AZ60M2 | Balanced | 7h (24h total) | LDAC/SBC/AAC | 3-device multipoint and call quality |
| EAH-AZ80 | Upper-tier | 7h (24h total) | LDAC/SBC/AAC | Sound quality and value balance |
| EAH-AZ100 | Flagship | 10h (28h total) | LC3/LDAC/AAC/SBC | No compromise on NC or sound |
All 4 Current Technics Noise-Cancelling Earbuds
Technics EAH-AZ40M2 — Entry model
| Driver | 6mm PEEK diaphragm |
| NC battery | Up to 5.5h (18h with case) |
| Codecs | SBC/AAC/LDAC |
メナGetting both noise cancelling and LDAC at the entry price point genuinely surprised me when I lined up the whole range side by side. If you want to try Technics for the first time, this is the one to start with.
The EAH-AZ40M2 is the most accessible earbud in the current Technics true wireless lineup. It uses a 6mm PEEK diaphragm driver in a compact housing while still packing in active noise cancelling.
Bluetooth 3-device multipoint means you can stay connected to a laptop and phone at once, which is genuinely handy for jumping between calls during the workday. LDAC support at this price is honestly generous — though there’s no wireless charging here, USB-C only.
At about 5g per earbud with IPX4 splash resistance, it holds up fine for workouts. For anyone curious about Technics NC earbuds without committing to a flagship price, I’d recommend this one without hesitation.
Technics EAH-AZ60M2 — Balanced pick
| Driver | 8mm aluminum diaphragm + harmonizer |
| NC battery | Up to 7h (24h with case) |
| Codecs | LDAC/SBC/AAC |
メナThree-device multipoint without juggling OS account logins is the kind of thing I only appreciate once I’m actually bouncing between a work laptop, personal phone, and tablet all day. Call quality holds up right alongside it.
The EAH-AZ60M2 succeeds the original EAH-AZ60, refining call quality and connection convenience. An 8mm aluminum diaphragm driver paired with a harmonizer and acoustic control chamber gets NC performance close to the higher-tier models.
LDAC support brings hi-res-equivalent sound, and Technics’ JustMyVoice technology suppresses background noise on calls so only your voice comes through clearly. Seven ear tip sizes make it easier to dial in a proper seal. NC-on battery life tops out at 7 hours per charge, a bit short of the AZ100 flagship, but plenty for daily use.
It also supports Qi wireless charging and weighs about 7g per side. For anyone on a lot of calls, I’d call this a genuinely strong pick on price and features.
Technics EAH-AZ80 — Upper-tier
| Driver | 10mm bio-cellulose diaphragm |
| NC battery | Up to 7h (24h with case) |
| Codecs | LDAC/SBC/AAC |
メナLining the AZ80 up against my usual daily-driver earbuds, the way the bio-cellulose diaphragm renders low-end definition is just clearly different. It feels like a genuine step up in build quality for an upper-tier model.
The EAH-AZ80 is the previous flagship in the Technics true wireless lineup. Its 10mm bio-cellulose diaphragm driver draws on acoustic engineering carried over from Technics’ Hi-Fi component business.
LDAC support gets you hi-res-equivalent sound, plus NC performance that closes in on the flagship. NC-on battery runs up to 7 hours per charge with 24 hours total including the case, so it holds up fine for commuting or travel without worrying about running out. Compared to the newer AZ100 flagship it’s a driver-generation behind and slightly heavier at about 7g per side, but that also keeps the price down — the value here is genuinely strong.
It supports Qi wireless charging and 3-device multipoint too. For anyone who wants good sound without paying flagship prices, I’d call this a serious contender.
Technics EAH-AZ100 — Current flagship
| Driver | 10mm magnetic fluid driver |
| NC battery | Up to 10h (28h with case) |
| Codecs | LC3/LDAC/AAC/SBC |
メナHearing the industry-first magnetic fluid driver for the first time, the way the low end just drops in cleanly was clearly different from every previous Technics earbud I’ve tried. It genuinely earns the flagship name.
The EAH-AZ100 is the current flagship in the Technics true wireless lineup. It packs an industry-first magnetic fluid driver into a 10mm size, paired with a dedicated aluminum diaphragm for clear yet deep bass.
It supports a wide codec range — LC3, LDAC, AAC, and SBC — and NC-on battery stretches to 10 hours per charge, 28 hours total with the case, so it holds up even on long-haul flights. Voice Focus AI cleans up both outgoing and incoming call audio, and it supports Dolby Atmos too. It’s honestly the priciest of the four models here, running more than double the entry-level AZ40M2 — a real trade-off to weigh.
It supports Qi wireless charging and weighs about 5.9g per side, light for a 10mm-driver earbud. For anyone who doesn’t want to compromise on NC or sound quality, this is the one I’d recommend without reservation.
Worth Having: Accessories for NC Earbuds
Beyond the earbuds themselves, a couple of accessories make day-to-day use noticeably more comfortable and keep you from getting stranded with a dead battery.
Replacement ear tips (silicone or foam)
If the stock ear tips don’t fit your ears well, seal quality drops and you lose a chunk of the NC performance you’re paying for. Silicone tips come in a wide range of sizes, while foam tips deform to your ear canal for a tighter seal. Worth trying if the stock fit ever feels off.
Fast-charging USB-C cable or power bank
The EAH-AZ60M2 and above all support Qi wireless charging on the case, but every model here also charges over USB-C. Keeping a fast-charging cable or power bank on hand means a short top-up buys you real playback time when you’re caught out with a low battery. Worth having if you travel a lot.
How This Article Differs From Our Cross-Brand Comparison
This article sticks to one brand — Technics — and lines up every current NC earbud model by price tier, a “full lineup within one brand” approach. If you’d rather compare the best pick across Sony, Anker Soundcore, and final, our separate cross-brand comparison article is the better starting point.
Across the Technics lineup, driver size (6mm to 10mm) and diaphragm material both change with price tier. If sound quality is the priority, go with a newer higher-tier driver; if you want to keep the price down while still getting real NC and LDAC, even the entry model delivers.
メナLining up all four Technics NC earbuds, my honest takeaway is that driver generation and NC performance both step up together as the price climbs. Pick based on how much you want to invest in sound quality and silence.
Bottom Line
We compared all 4 current Technics NC earbuds across NC performance, fit, battery life, and codec support. Even the upper-$100s EAH-AZ40M2 delivers real NC and LDAC, and stepping up to the roughly $250 flagship gets you the difference an industry-first magnetic fluid driver makes to sound quality.
Want to try Technics on a budget? Go with the EAH-AZ40M2. Want 3-device multipoint and strong call quality? The EAH-AZ60M2. Want a sound-quality/value balance? The EAH-AZ80. Not willing to compromise? Consider the EAH-AZ100.
