The Ultimate Showdown: KZ ZSTX vs. KZ ZS10 - Battle of the Professional In-Ear Monitors

Is your church planning to implement in-ear monitoring, or are you currently relying on inexpensive earplugs that may not deliver the desired results? While there are numerous high-end options available, some exceeding $1,000, rest assured that there are very affordable options that we have personally used ourselves for many years.

When it comes to in-ear monitors (IEMs), musicians and audiophiles alike are always on the hunt for the perfect blend of comfort, sound quality, and affordability.

Several well-known brands have dominated the market, such as Shure, Westone, Sennheiser, and Alclair, to name a few, but today, we are going to focus on a couple of underdogs under $50 that have been making waves in the worship musician community - the KZ ZSTX and KZ ZS10. In this blog post, we'll compare these two contenders and find out why they have emerged as the winners among our choice of in-ear monitors.

  1. Sound Quality:

One of the most critical factors in choosing an IEM is its sound quality. The KZ ZSTX and KZ ZS10 both deliver exceptional audio performance but cater to different preferences.

  • KZ ZSTX: The KZ ZSTX offers a well-balanced sound signature with a focus on midrange frequencies. The vocals are clear and prominent, making it an excellent choice for vocalists and instrumentalists who need to hear themselves clearly on stage. The bass response is tight and controlled, enhancing the overall listening experience.

  • KZ ZS10: On the other hand, the KZ ZS10 leans towards a V-shaped sound signature. This means it emphasizes both the bass and treble frequencies, resulting in a more energetic and exciting sound. Musicians who enjoy a punchy low-end and sparkling highs will find the KZ ZS10 more to their liking.

  1. Build Quality and Comfort:

Professional musicians and performers often wear IEMs for extended periods, making comfort and durability crucial factors in their choice.

  • KZ ZSTX: The KZ ZSTX features a lightweight plastic shell with a compact design, providing a comfortable fit for most users. However, some may find the fit to be less secure compared to custom-molded IEMs. The build quality is satisfactory but not as robust as higher-end IEMs.

  • KZ ZS10: The KZ ZS10 sports a more ergonomic design with its resin shells, which enhances comfort during extended use. Additionally, the build quality of the ZS10 is an improvement over the ZST, making it more durable and resilient.

Winner: KZ ZS10

  1. Price:

While professional IEMs can be quite expensive, the KZ ZST and KZ ZS10 are known for providing remarkable value for their price.

  • KZ ZSTX: As an entry-level IEM, the KZ ZST is remarkably affordable for the features it offers. This makes it an excellent option for beginners or musicians on a budget who still want to enjoy high-quality sound.

  • KZ ZS10: Despite being slightly more expensive than the ZST, the KZ ZS10 is still significantly more affordable than many other professional-grade IEMs on the market. Considering its sound quality and build, the ZS10 is a solid investment for any musician.

Winner: KZ ZSTX (for budget-conscious users)


Both the KZ ZSTX and KZ ZS10 are exceptional contenders in the realm of professional in-ear monitors. Ultimately, the winner depends on your individual preferences and requirements.

If you prefer a balanced sound signature with clear midrange and controlled bass, the KZ ZSTX is the way to go, especially for those on a tight budget. On the other hand, if you crave a more dynamic and energetic sound with a punchy low-end and sparkling highs, the KZ ZS10 is the better option. Additionally, the ZS10's improved build quality and comfort make it a top choice for extended on-stage use.

In conclusion, both the KZ ZSTX and KZ ZS10 prove that exceptional sound quality and comfort can be achieved without breaking the bank, making them the ultimate winners in the world of professional in-ear monitors.

I personally used both models for many years and have recommended them so many times! I replaced the tips with the memory foam tips for better sound and fit.
