Technics’ intriguing new flagship wireless earbuds feature ‘Magnetic Fluid’ injected between the driver magnet and voice coil
- Magnetic Fluid Drivers from Technics’ high-quality niche IEMs
- Improved active ANC and even clearer voice calls
- £259 / €299 / $299 (subject to change)
It’s a big day at CES 2025: Technics has announced a follow-up to its fantastic EAH-AZ80 earbuds. Called the EAH-AZ100, they promise to retain all the impressive benefits of their predecessors, but also improve sound quality and noise cancellation.
There are three major upgrades here. The first is a proprietary Magnetic Fluid Driver that, according to Technics, delivers “ultra-low distortion, high-resolution audio and precise, rich bass.”
The second big improvement is called Voice Focus AI, and as the name suggests, it’s designed to make your voice sound better during calls. It uses multiple microphones and a new intelligent algorithm to remove wind noise and other unwanted noise in real time.
And the third is improved active noise cancellation, with conversation mode so you can hear people without taking out your earbuds. Oh, and the units are also 10% smaller and 16% lighter, as a quick look at the image below shows (AZ80 on the left; new AZ100 on the right). This downsizing was helped by the fact that the feedback microphone you can just see on the teardrop-shaped older knob is now located on the side of the sound tube, allowing Technics to make the AZ100’s top plate truly spherical.
Technics EAH-AZ100: key specifications, prices and availability
The new driver is a miniaturized version of the one in the company’s 2019 EAH-TZ700 wired IEMs (acclaimed, but only launched in Europe), whose recommended retail price is a hefty $1,200. Don’t worry, Technics has miniaturized both the price and the driver.
Interestingly enough, the “Magnetic Fluid” in that Magnetic Fluid Driver is actually “an oily fluid filled with magnetic particles that is injected into the space between the driver magnet and the voice coil,” but here again there is no cause for concern – the headphones from Technics Project Manager Ryan Yu assures us that there is absolutely no chance of liquid leakage from the earbuds.
The new driver (which is still 10 mm in size) promises tight, rich bass with an aluminum diaphragm providing the details. The earbuds support Dolby Atmos and Dolby Audio, and this time there is also Bluetooth LE with Auracast, LDAC, LC3 low-latency and Google Fast Pair. Battery life is 10 hours without the case and 28 hours with it; that’s with ANC enabled, so a big improvement over their predecessors.
This is no small update considering that the EAH-AZ80 arrived on the scene as the only product with a three-device multipoint function and with Technics’ own ‘concha-fit’ design that wowed us under intense reviews and quickly became the took first place. in our best earbuds buying guide. Suffice to say, we really liked the EAH-AZ80 earbuds, and on paper at least the EAH-AZ100 are even better. So it will be very interesting to see how they compare to their direct competitors, the Bose QuietComfort Earbuds 2024.
And it just so happens that we have a pair of Technics EAH-AZ100 and tested them for you. Normally at this point we would have to tell you to write another full review soon, but it just so happens that our Technics EAH-AZ100 review may go live at the same time as this mission. (Spoiler alert: It’s very good news.)
The new Technics EAH-AZ100 has an MSRP of $299 / £259 / €299 (which would make them around AU$519).
