KZ ZA12 Review: Best Budget Hybrid IEM with 2DD+4BA Drivers

KZ, known for delivering high-quality in-ear monitors (IEMs) at competitive prices, has introduced the ZA12, a hybrid IEM featuring two dynamic drivers (DD) and four balanced armature (BA) drivers per side. This configuration aims to provide a rich and detailed sound experience. In this article, we delve into the design, sound quality, and overall performance of the KZ ZA12.

Design and Build Quality

The KZ ZA12 boasts a modern and sleek design. The faceplates have a subtle metallic sheen with angular cuts, giving the earpieces a futuristic aesthetic. The translucent resin shells allow a glimpse into the internal driver configuration, adding to its visual appeal. The IEMs fit snugly in the ear, maintaining a low-profile look, which makes them comfortable for extended use. The included detachable 2-pin cable is of decent quality, though it feels somewhat basic compared to the premium appearance of the IEMs.

Sound Quality

Bass

The bass is tactile and snappy, with minimal bleed into the mids. It delivers a satisfying slam when required, especially when driven well. While not at a basshead level of impact, it offers enough texture and body to keep listeners engaged. However, some tracks may leave listeners wanting more rumble and grunt in the sub-bass.

Midrange

The ZA12's midrange is one of the best from KZ or CCA sets. It's generally neutral, with decent clarity and detail. Vocals are forward and possess a natural timbre, with both male and female vocals reproduced equally well, exhibiting little to no sibilance.

Treble

The treble is energetic, with a good amount of air and impressive resolution. It stops short of being overly bright, though some listeners might find it too pronounced. The treble's extension contributes to a strong sense of air and "sparkle" in the music.

Technicalities

The ZA12 excels in resolution, offering a forward positioning of sound that enhances detail retrieval. However, this characteristic slightly restricts the soundstage. Imaging is decent, and layering is excellent. The timbre is relatively natural, and the coherence between drivers is surprisingly good.

Tuning Switches

The ZA12 features four tuning switches, allowing users to adjust the bass and treble levels to their preference. The switches provide various combinations to fine-tune the sound signature, enhancing the IEM's versatility.

Comparisons

Truthear Hexa ($90)

The Hexa was considered a technical bang-for-the-buck set upon release, though with a somewhat plain tonality. The ZA12 replaces that position, offering arguably better tonality. The mids and vocals are thicker in the ZA12, and the resolution is notably better. While the Hexa's build quality is superior, the ZA12 is preferred in terms of sound quality.

Tangzu Fudu Verse ($90)

The Fudu offers a thicker, warmer version of the Hexa, with similar technicalities. The ZA12 has a more reserved bass but excels in resolution and layering. The Fudu is more laid-back, making the ZA12 suitable for critical listening and the Fudu for relaxed sessions.

Conclusion

The KZ ZA12 is one of KZ's best releases in recent memory. Despite some issues with build quality, the sound quality compensates, especially at this price point. While the sound may be thin for some, with great technical ability yet a bright tonality not properly counterbalanced by a healthy amount of low-end, it remains a commendable offering.
