When I wear the IEM, it was not uncomfortable but you definitely can feel its presence in the ear. You had to kind of stick the protruded nozzle awkwardly into your ear canal and turn it khổng lồ achieve a proper seal. It’s neither difficult nor cumbersome but it could have been more intuitive.

Noise Isolation

There is a decent amount of noise isolation from the IEM. At around half of the max volume, most external noises are filtered.

Sound Leakage

I don’t know what wizardry goes into the KZ ATE but I hardly get any sound leakage out of the IEM. Cảnh báo that I tested this at a volume (a quarter from the max volume) which I almost find unbearable.

Technical Specs

Cable: 1.3mImpedance: 16ΩSensitivity: 106dBFrequency Response: 15 – 29kHzWeight: 24g

With 16Ω impedance và a sensitivity of 106dB, you can easily drive the IEM up khổng lồ 110 DPSL with smartphone devices. You can check the math with our tai nghe Power Calculator.

KZ ATE Sound Quality

The KZ ATE has a decent amount of soundstage. It is not as wide as the Carbo Tenore but in Bubble by Yoshi Horikawa, I’m able khổng lồ get a good amount of depth in sound imaging.

In Save the World by Swedish House Mafia, the bass response has quantity và attack but it is lacking in weight. In Unfinished Sympathy by Massive Attack, the bass also doesn’t sound as defined as what we get from the Tennmak Pro.

The sub bass reproduction in KZ ATE is surprisingly good. You can hear the sweet rumble in Intro by Yoshi Horikawa.

The mids is the highlight of the KZ ATE. The crispness & the depth of the mids alone make the KZ ATE worthwhile. In Leave Me by Taska Black, the cello opening brings me chills. The quality of the mids is what you find in IEMs that are 10x – 20x more expensive.

Vocals performance on the KZ ATE is ace too. Creep by Radiohead và Hide and Seek by Imogen Heap sounded intimate and rich. I totally enjoyed those songs on this budget IEM.

As for the treble performance, violin pieces sounded great but there are some roll-off in the upper treble. In Rude by Daniel Jang, I don’t hear that sparkle that I get from other IEMs like SoundMagic E80C.

Sound Signature

Overall, the sound signature of the KZ ATE is suitable for someone who likes forwards mids. You get lớn enjoy the lush performance of the mids without being drowned out by the bass or treble.


Music is not overly smooth-out & there is a good amount of details in the presentation. For songs that have complex layers like Dreams by Adventure Club, each layer has enough space to shine and are not drowned by one another.


If you are looking to lớn upgrade your stock earbuds lớn an audiophile IEM while keeping lớn a low budget, you should start with the KZ ATE.

An IEM with great sounding mids & decently build, it is one of those worthwhile buys that you can ever find on the internet.

Admittedly, the bass could be better but I’m not complaining. For less than $15, the KZ ATE has already brought me a long way.
