KZ, a Chinese manufacturer, has gained popularity for offering headphones that provide good sound quality at affordable prices. Its catalog ranges from models with hybrid driver systems and manual adjustments for greater frequency range, to more basic options focused on balanced sound, with fewer features and excellent cost-benefit.
Tecnoblog compiled a list with ten suggestions of KZ headphones suitable for both casual and professional use, detailing the advantages and limitations of each.
KZ ZS12 Pro X
This model is recommended for those looking for a versatile in-ear monitor. Its hybrid configuration, combining a 10mm dynamic driver with balanced armature (BA) drivers, optimizes the reproduction of bass and treble tones. Furthermore, its metallic structure, made of zinc, appeals to users who value a more durable finish.
The device has a frequency range between 20 Hz and 40 kHz, and the Tuning version allows adjustment of these ranges via selector switches. However, the built-in microphone is only available in certain editions.
KZ Duonic
The KZ Duonic is ideal for those who want a versatile in-ear monitor, presenting a balance between bass, mids, and treble, while also offering options to customize the sound signature. It incorporates an 8mm superlinear dynamic driver alongside a three-magnet planar magnetic driver. Its frequency response ranges from 10 Hz to 20 kHz.
There is also a variation of the KZ Duonic equipped with switches and enhanced bass, aimed at those who prefer to feel the low frequencies more. All models of this type come with a dual integrated microphone and ENC to improve call quality. Although it is wired, an extra module can be purchased separately to enable Bluetooth connection.
KZ AS24 Pro
For users who prioritize clarity and frequency separation, the KZ AS24 Pro is indicated. It uses 24 balanced armature drivers (twelve on each side) dedicated to reproducing bass, mids, and treble, making it a choice for more demanding audiophiles seeking a highly detailed sound experience.
Even without a dynamic driver, KZ headphones utilize specific BA drivers for bass, mids, and treble, ensuring broader sound coverage. This peripheral operates at a frequency of 20 Hz to 40 kHz and features a 3D printed casing optimized for acoustics. However, only selected models have a built-in microphone.
KZ ZSX Pro
The KZ ZSX Pro is suggested for those who value detail, vocal and instrument definition, and greater prominence in the treble, rather than very powerful bass. It features a hybrid system composed of a 10mm dynamic driver and five high-frequency BAs.
The frequency response of this peripheral is 20 Hz to 40 kHz. Other features include an ergonomic design, low distortion, and high-fidelity output. The version that includes multi-function control offers adjustments for playback and calls, with an integrated microphone, but costs more than the basic version without a microphone.
KZ ZS10 Pro 2
This model represents an update to one of the brand's most popular headphones. It combines a 10mm dynamic driver (responsible for low and mid frequencies) with two BA drivers (in each earphone) focused on treble. Additionally, the new crossover circuit contributes to greater balance across the three frequency bands.
A notable feature is the presence of four selector switches that allow adjustment of the frequency response in the range of 20 Hz to 40 kHz. Furthermore, this is the only headphone on the list cataloged by KZ as being aimed at eSports professionals, featuring a USB-C output option.
KZ Castor Pro
The KZ Castor Pro is indicated for those seeking a headphone with a versatile sound signature, manual adjustment capability, and good bass presence, making it an interesting alternative for those who like to customize their audio experience. It has an in-ear design and is equipped with two dynamic drivers, one of 10mm and another of 8mm. One driver focuses on reproducing 20 Hz to 200 Hz, while the second handles mids and treble.
The headphone follows the Harman curve, which serves as a reference for sound tuning. Additionally, it has keys for manual audio adjustments, electronic crossover technology, and a frequency response of 20 Hz to 40 kHz. There are four versions available, including variants with microphones and enhanced bass.
KZ AS16 Pro
The KZ AS16 Pro is recommended for those seeking precision, definition, and separation between different frequency ranges. It has eight balanced armature drivers per side and a three-way crossover, primarily catering to users who prioritize accuracy in music reproduction.
With an in-ear design, it does not have ANC, but it offers passive noise cancellation exceeding 26 dB. The frequency response is 20 Hz to 40 kHz. The cable, made with silver-plated OFC core, helps reduce signal transmission loss. There are no manual switches for sound adjustments, as seen in other models from the brand, and the microphone is present only in some variants.
KZ ZSN Pro 2
This is a more basic in-ear monitor, configured with one dynamic driver and one BA driver per ear. Even so, KZ has improved the BA driver structure to reduce distortion rate and capture more detail in high frequencies. The peripheral's response is 20 Hz to 40 kHz, and the crossover circuit aims to smooth the acoustic curve for clearer and more precise sounds.
The device is available in white, gold, or blue colors, with options with or without a built-in microphone.
The KZ D-Fi is suggested for those looking for an entry-level in-ear monitor and wish to test different sound profiles. It features a customized dynamic driver (10mm) with a double magnet and cavity, making the headphone more efficient and capable of achieving better transient response performance. One of its striking features is the frequency response between 7 Hz and 45 kHz, offering a wide range of bass to treble reproduction. The Tuning version also provides four frequency adjustments for personalized sound according to user preference.
KZ EDX Pro 2
The KZ EDX Pro 2 is indicated for those who need an affordable in-ear monitor with balanced sound and a simple concept. It is an attractive option for IEM beginners or for those who do not care about customizing the sound signature. It comes equipped with a single 10mm superlinear dynamic driver, has fixed factory tuning, and does not include selector switches for sound adjustments. Its specifications include a frequency response between 10 Hz and 20 kHz and a resin casing.
