The KZ AS10 Pro is the latest iteration from Knowledge Zenith (KZ), a brand known for delivering high-quality audio equipment at budget-friendly prices. Positioned as an upgrade to the original AS10, the AS10 Pro aims to refine its predecessor’s formula by improving sound quality, design, and overall usability. In this review, we’ll dive into its features, performance, and value to help you decide if it’s the right choice for your audio needs.

Key Specifications

  • Driver Configuration: 5 Balanced Armature (BA) drivers per earbud.
  • Frequency Response: 20Hz – 40kHz.
  • Impedance: 30Ω.
  • Sensitivity: 110dB.
  • Connector: 2-pin 0.75mm.
  • Cable: Silver-plated detachable cable.

Design and Build Quality

The AS10 Pro boasts a sleek and modern design, featuring transparent resin shells that reveal the intricate arrangement of its five BA drivers. The metallic faceplate not only adds a premium touch but also enhances durability. These IEMs feel lightweight yet sturdy, making them suitable for extended listening sessions.

The detachable 2-pin cable is silver-plated, ensuring better signal transmission and reducing microphonics. While the included cable is functional, users looking for higher durability or aesthetic customization might consider upgrading to an aftermarket option.

The earbuds are ergonomically designed, offering a snug fit that minimizes sound leakage and enhances passive noise isolation. Multiple ear tip sizes are included to accommodate different ear shapes and ensure optimal comfort.

Sound Quality

One of the standout features of the KZ AS10 Pro is its audio performance, especially considering its price point. Here’s a breakdown of its sound signature:

Bass

The bass is tight and controlled, thanks to the dedicated BA driver for low frequencies. It lacks the exaggerated thump of dynamic drivers but compensates with precision and clarity, making it ideal for genres like classical, jazz, and acoustic.

Midrange

Vocals and instruments shine with excellent detail and separation. The mids are slightly forward, providing an intimate and engaging listening experience. However, some users might find the upper mids a bit pronounced, which can make certain tracks sound harsh.

Treble

The treble is crisp and airy without being overly sibilant. High frequencies are well-extended, providing clarity and sparkle, though some sensitive listeners might perceive slight harshness in certain recordings.

Soundstage and Imaging

The AS10 Pro offers a decent soundstage for an IEM, with good depth and width. Imaging is precise, allowing listeners to easily pinpoint instrument placement in complex tracks.

Comfort and Usability

The ergonomic design of the AS10 Pro ensures a comfortable fit, even during long listening sessions. The included ear tips provide adequate noise isolation, though audiophiles may want to experiment with foam tips for an even better seal.

The detachable cable is a welcome feature, allowing for easy replacement in case of damage. However, the lack of an inline microphone or remote control might be a drawback for those planning to use these IEMs with smartphones.

Pros and Cons

Pros

  • Exceptional sound quality for the price.
  • Sleek and durable design.
  • Comfortable fit with good noise isolation.
  • Detachable silver-plated cable.
  • Detailed mids and crisp treble.

Cons

  • Upper mids can be harsh on certain tracks.
  • Lack of inline microphone or remote control.
  • Treble might be too bright for sensitive listeners.

Who Should Buy the KZ AS10 Pro?

The KZ AS10 Pro is a fantastic choice for budget-conscious audiophiles seeking a detailed and balanced sound signature. It’s particularly well-suited for genres that prioritize clarity and instrument separation, such as classical, acoustic, and jazz. However, listeners sensitive to pronounced upper mids or treble may want to consider other options.

Conclusion

The KZ AS10 Pro delivers impressive performance at an affordable price, cementing KZ’s reputation as a leader in the budget IEM market. With its refined sound quality, durable design, and comfortable fit, it’s hard to find a better value in this price range. While it may not be perfect, its strengths far outweigh its minor drawbacks, making it a worthwhile investment for those seeking high-quality audio without breaking the bank.
