Kiwi Ears Atheia is an earphone that basically merges a 50 mm dynamic driver with a 14.5 mm planar magnetic driver, thereby giving you punchy bass, crystal clear treble, all combined in a nice little package. Not only does this mouthwatering frequency range of 20 Hz to 40 kHz open up the minutiae, from the lightest ply of a string to the growl of a live drum solo, but it’s all very stunningly crafted from walnut wood ear cups, aluminum alloy brackets, and vegan leather.
By now, you would be wondering how two drivers harmonize effortlessly. Well, let’s get down to the nitty-gritty as to why having Atheia would seem like having a concert hall around your ears. Lind, D, and E head off for the adventure that the Atheia dual driving technology affords. So, indeed, presenting the best of both worlds.
The dynamic bass driver is combined with a planar magnetic one for mid and high frequencies-all of this with a racing car engine and finely tuned precision instrument under one hood-you get raw power and finesse together.
I have received this Atheia in exchange for a review, and Kiwi Ears has no say in my writing and my comments.
Dynamic Driver: Punch of 50 mm
At the heart of Atheia is a 50 mm dynamic driver, which gives you deep and punchy bass that you can feel in the chest. Dynamic drivers are able to shift a lot of air, generating the thunderous lows that make genres like EDM and hip-hop so enjoyable in the first place.
14.5 mm Clarity of Planar Magnetic Precision
A 14.5 mm planar magnetic driver makes its debut, coupled with the dynamic one and is famous for delivering low distortion and quick transient response. This driver complements, almost automatically, what voices and other string instruments sound like every time you listen, as if the performers are in the room with you.
Balanced Response of Frequency
Range-wise, at 20 Hz through to a crazy 40 kHz, Atheia catches everything from the rumble of bass pedals to the shimmer of cymbals without so much as a missed beat. Such a wide bandwidth will have you hearing details lesser headphones cannot reproduce.
Low Distortion & High Fidelity
This by a 0.5% THD (Total Harmonic Distortion) at 1 mW: the Atheia preserves clarity, even at louder volumes, and keeps the music pure, not muddy. Another of the benefits of having a planar magnetic technology is low distortion, which results from a more uniform diaphragm drive.
Luxury Materials and Build
The walnut ear cups of Atheia look drop dead gorgeous but also work on unnecessary resonance management, delivering a warmer, more natural tone. Vegan leather ear pads and an aluminum alloy frame guarantee long life and a deluxe feel every time you press play.
The Atheia is really flexible, which also makes it a great headphone for your head.
Ergonomics & Comfort
Horrifying hours? Not a problem. Atheia has a self-adjusting headband and independently adjustable ear pods that make long wear comfortable and a perfect fit for all shapes of heads. Like wearing a cloud while it plays to you.
Harman-Emulation Tuning
Atheia tunes Harman so that it lies tangentially between neutral accuracy and its engaging outlet of musicality. This emulation is exactly how our ear perceives sound; we create lifestire as well as emotion in the tracks.
Quick technical specifications
- Drivers: 50 mm Dynamic + 14.5 mm Planar Magnetic
- Frequency response: 20 Hz~40 kHz
- Impedance: 32 Ω ±10%

Comparison With Other Headphones
Compared to other planar-only offerings, such as Audeze’s LCD-1 ($399), Atheia would be capable of portraying dynamic bass warmth beside planar detail-without the need of a high power amp WIRED. Compared to an entry-level planar model such as the HiFiMan HE400S ($299), Atheia provides a more well-balanced tuning that’s more casual-listener-friendly
Conclusion
For all those who want the features of versatility, comfort, and sound fidelity, the Kiwi Ears Atheia will be right for you. It is like having in your audio kitchen a master chef and a healthy eater dining together-rich, flavorful, and balanced.
The Kiwi Ears Atheia is great, really! I enjoyed working and playing with them, immensely!
The absolute only small thing I don’t like, is the placing of the 3.5 mm jacks. They have to be pulled out when taking it along in your bag. And frankly… I am way to lazy to do so. So I’d then rather put the headphone in my backpack then having to hook up and unhook the cable. With $349,- dollars I this is really the only downfall of this headphone.
The Atheia gets 4 out of 5 stars, just because of the placing of the cable in the case.
The Kiwi Ears Airoso got 5 out of 5 stars, which are absolutely great in ears!
