Following up an excellent set of earbuds can be a challenging task. The goal is to enhance the product while retaining the features that users love. This is the challenge Technics faced with its recently unveiled $299.99 EAH-AZ100 earbuds at CES 2025. I was impressed with the previous flagship model, the AZ80, known for its rich audio quality and unique ability to simultaneously connect with up to three devices. The new AZ100 earbuds aim to build on these strengths by offering even more immersive sound, extended battery duration, and improved active noise cancellation.
Technics has reimagined the fundamental audio output as well. The A100s are equipped with groundbreaking “magnetic fluid” drivers, which contain actual fluid. This innovative design—featuring an oily substance blended with magnetic materials between the driver magnet and voice coil—promises to reduce distortion and enhance clarity, a step forward from what the AZ80s offered. Bass performance is also significantly improved, allowing the AZ100s to produce deeper, more powerful low frequencies. While both models offer exceptional sound clarity across various music styles, the AZ100s deliver enhanced depth and bass response. However, I wouldn’t recommend an upgrade solely for this reason.
$300
Pros
- Exceptional audio quality
- Three-way multipoint connectivity
- Enhanced comfort design
Cons
- Overwhelming app features
- Noise cancellation could be improved
- Less distinctive design
The design of the AZ100s has also seen significant upgrades. They are less bulky than their predecessors, although the absence of the visible microphone inlet may make them appear a bit more generic. However, the decreased size translates to improved comfort during wear. The accompanying case is slightly smaller and more portable, though the difference is subtle. As for durability, the earbuds maintain an IPX4 water resistance rating.
For those who find the default sound signature lacking, multiple EQ presets are available, including the option to save three custom profiles. While not typically relying on frequency charts for sound assessment, I have a wealth of experience with different earbuds. The AZ100s rank high among my favorites, easily surpassing models like the Sennheiser Momentum True Wireless 4, and outperforming the AirPods Pro 2 and Galaxy Buds 3 Pro. They also support advanced Bluetooth codecs, such as LDAC and the newest LC3/LE Audio protocol, which means the AZ100s should eventually be compatible with Auracast technology.
Technics has embraced spatial audio technology with the new earbuds. Their companion app includes a Dolby Vision toggle (optional head tracking), enhancing the listening experience and adding an immersive quality for those who appreciate it. While this feature may not appeal to everyone, it’s certainly an interesting addition for fans of expansive sound.
The Technics app is packed with features that extend beyond adjusting controls or the ambient noise filtering in transparency mode. Users can fine-tune the noise cancellation using a slider tailored to their environment. If you want the multipoint connection to switch automatically when playing music on different devices, that’s also an option. Additionally, users can test their microphone quality by recording snippets of their voice. There’s a lot of functionality here, which might be overwhelming for some users, but it also highlights Technics’ commitment to innovation.
The active noise cancellation (ANC) performs reasonably well, although achieving a good seal with the right ear tips is crucial. While it doesn’t match the exceptional performance of the Bose QuietComfort Ultra Earbuds—which provide superior ANC at a lower price—the sound quality remains impressive. Call quality is also noteworthy; Technics’ Voice Focus AI excels in isolating your voice amid background noise. In outdoor tests, some callers remarked that I sounded slightly robotic during loud moments, but clarity was still maintained.
A standout feature of the AZ100s is their three-way multipoint functionality. While I may not consistently use more than two devices, the third disconnection works seamlessly when needed (note that LDAC is disabled in this mode, likely due to Bluetooth limitations). Battery life is also impressive, lasting up to 10 hours on a single charge with ANC activated, while the charging case provides an additional 28 hours.
Much like their predecessors, the Technics AZ100 earbuds excel in audio quality while offering a unique feature that sets them apart from the competition—something both AirPods and Galaxy Buds lack. With their smaller size, enhanced comfort, and longer battery life, the AZ100s make for a compelling choice. For those who don’t require the unique three-way multipoint support, the price tag of $300 might seem high. However, it’s increasingly rare to find earbuds that boast features that most others cannot, making the Technics flagship buds a distinctive option.
