Super Lightweight


KZ returns with a brand-new in-ear monitor (IEM) called the Castor, featuring a dual-dynamic driver setup. The Castor is equipped with two dynamic drivers, a 10mm driver alongside an 8mm driver, working in tandem to provide a highly engaging listening experience. Additionally, the Castor incorporates four tuning switches, enabling subtle sound adjustments. These switches offer the versatility to create 16 distinct audio profiles, each tailored to individual preferences and suitable for various music genres. The KZ Castor promises to deliver an immersive and customisable listening experience.



The KZ Castor incorporates a dual-driver setup featuring a 10mm dual magnetic dynamic driver coupled with an 8mm dynamic driver, arranged in a stacked cavity structure at both the top and bottom, ensuring exceptional audio quality and an enriched listening experience. Specifically, one driver is dedicated to handling frequencies within the 20-200Hz range, primarily responsible for delivering bass output, while the other driver is tasked with reproducing mid and high frequencies. This arrangement is facilitated by precise electronic crossover technology, enabling the two drivers to work harmoniously without interfering with each other's frequencies. Moreover, the Castor adopts a top and bottom-stacked cavity design to strike a balance between sound quality and wearer comfort, resulting in a more compact earphone size and an improved level of comfort during prolonged use.



In the past two years, an increasing number of audiophiles have pursued a higher degree of adherence to the Harman Frequency Response (FR) curve, which many brands reference for their flagship products. However, achieving this curve's precision in acoustic tuning is challenging, leading some brands to only moderately fine-tune their flagship products, while lower-priced options, constrained by technology and cost, often deviate from this tuning style. KZ Castor disrupts conventional acoustic tuning methods with its innovative dual-dynamic driver design, resulting in a flawless Harman curve that outperforms flagship offerings from other brands. Furthermore, the KZ Castor's tuning follows the Harman Target with enhanced bass response, providing that extra thump to align with your music-listening preferences.



The KZ Castor is equipped with four tuning switches, each providing two-stage adjustments for both low and high frequencies. These switches enable the creation of 16 distinct audio profiles tailored to individual preferences, catering to a wide range of music genres. Each profile undergoes precise tuning, with specific impedance and sensitivity settings meticulously configured to deliver the best possible audio output, aligning with various sound preferences. Enabling the first switch increases bass by 1dB, activating the first and second switches results in a 2dB bass increase, engaging the first, second, and third switches boosts mid and high frequencies by 1dB, and with all tuning switches enabled, the midrange and high frequencies receive a 2dB increase.



The KZ Castor In-ear monitor incorporates an advanced integrated injection moulding process to create a highly precise acoustic filtering nozzle that is seamlessly integrated into the earphone. This sophisticated manufacturing method allows for the accurate and intricate printing of complex internal structures within the earphone cavity. Notably, the precision achieved through this integrated injection moulding process exceeds that of traditional 3D printing technology by more than tenfold. While the tolerance range of 3D printing is approximately 0.1mm, the precision of the internal support structure in the KZ Castor reaches an impressive 0.01mm. Consequently, the KZ Castor excels in delivering efficient and consistent sound reproduction, elevating overall audio quality and providing a more immersive listening experience.



The KZ Castor ensures a superb and comfortable wearing experience, even during extended use, without causing fatigue. Its design prioritises a secure fit, preventing any risk of falling out. This IEM (In-ear Monitor) includes an in-line microphone compatible with standard mobile phone calls and offers in-line media controls, enabling functions such as call management, pause/play, and song switching with just a few button presses. The KZ Castor also incorporates premium memory foam ear tips with an optimised physical structure to significantly reduce discomfort from teeth clenching noise. The slow rebound memory sponge material enhances comfort and provides excellent noise reduction and sound isolation effects. Additionally, the KZ Castor comes with a flat, transparent black cable featuring a 0.75mm 2-pin plug design to enhance audio quality, further enhancing your listening experience.

Praveen (Hyderabad)
Really good for the price

As advertised, Castor (bass) has better bass by default and when you use the turn switch, you can increase it much more. Out of the box, switches 3 and 4 were turned on. I turned them off to compare it against MoonDrop Chu 2 and I kind of still like Chu 2. I loved the foam tips though (experiencing it for the first time) and it gives a decent passive noise cancellation (isolation, maybe?)

The reason I'm giving 5 stars is because it is as promised. The bass is good and one can tune it using the turn switches (4 switches => 16 unique combinations) as per their liking.

For a similar budget, it's better to go with Chu 2 unless you want that extra bass or the ability to tune.

Hey Praveen, thank you so much for the amazing feedback! It means a lot to us. We are so happy to hear that you are loving our products and services.

KZ Best Sound Quality with better thump in Bass

I have already used KZ ZSN Pro X. Now i bought KZ Castor also. Below are the gears i used.

Mobile : One Plus 8T
DAC & Amp : iBasso DC03
Wireless Module : KZ AZ09 Pro

I have tested this with wired along with a DAC & Amp and also wireless using a wireless module as well. So obviously it sounds lot better with wired compared to wireless as i use DAC & Amp. Compared to KZ ZSN Pro X, bass is much better in Castor but mids are better in KZ ZSN Pro X. If you love to hear music with thump bass, better to go with KZ Castor. If you like it balanced, go with KZ ZSN Pro X. Also you have 4 tuning switches which you can use to customize the sound as per your taste. using these 4 tuning switches, you can create 16 sound stages. However you cannot see high change in these sound stages but you ll definitely see slight changes.

Overall a great chance of IEM with thump bass and that too pricing around 1800. A must go for bass lovers.

Thanks a lot for your detailed and genuine feedback, we're glad that you have such positive thoughts about the product and we'll share your thoughts with the brand as well. It'll also help our fellow customers to make the right choice!
