DESCRIPTION
KZ PUSHES THE BOUNDARIES OF WHAT A BUDGET IEM CAN DELIVER WITH THE ALL-NEW CASTOR
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.
FEATURES DUAL DYNAMIC DRIVERS IN A TOP AND BOTTOM STACKED CAVITY STRUCTURE
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.
METICULOUSLY TUNED FOLLOWING THE HARMAN TARGET CURVE WITH ENHANCED BASS
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.
TAILOR AND CUSTOMISE THE SOUND PROFILE TO YOUR LIKING WITH TUNING SWITCHES
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.
LEVERAGES A HIGH-PRECISION INTEGRATED INJECTION MOULDING PROCESS FOR ELEVATED SOUND
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.
ERGONOMICALLY DESIGNED WITH IN-LINE CONTROLS AND BUNDLED WITH FOAM TIPS AND CABLE
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.

How do the tuning switches work?
The KZ Castor features four tuning switches that allow you to make adjustments to the sound profile. Enabling different combinations of these switches creates 16 distinct audio profiles, catering to individual preferences and various music genres.
Is the KZ Castor comfortable to wear for extended periods?
Yes, the KZ Castor is designed with comfort in mind. It offers a secure fit to prevent falling out and includes memory foam ear tips that reduce discomfort from teeth clenching noise.
What type of cable does the KZ Castor use, and how does it enhance audio quality?
The KZ Castor comes with a flat, transparent black cable featuring a 0.75mm 2-pin plug design. This design is aimed at improving audio quality, enhancing the overall listening experience.
How do I use these IEMs if my phone does'nt have a 3.5mm output?
If your phone doesn't have a 3.5mm output, you can use a USB-C to 3.5mm adapter for android phones or a Lightning to 3.5mm adapter for Apple iPhones to connect the KZ Castor IEMs.
Alternatively, the best-sounding option is to go for a USB Digital-to-Analog Converter (DAC) to connect your IEMs. A good DAC makes a considerable difference to the overall sound of your set up and these DACs are highly capable and outperform inexpensive adapters. If you are looking for the best presentation of your music then a dedicated USB DAC is the way to go.
Do I really need a Digital To Analog Converter (DAC) or Amplifier to use these IEMs?
You don't necessarily need a Digital-to-Analog Converter (DAC) or Amplifiers to use the KZ Castor IEMs, as they can be plugged directly into the 3.5mm output of your smartphones, tablets or laptops. They usually have enough power to drive these Earphones. However, using a dedicated DAC can improve the overall sound quality and provide a more detailed reproduction, especially if you are listening to Lossless or Hi-Res music.

Customer Reviews
I heard music in my musician friend's Fiio IEMs and I was mesmerized by the quality of it. So I decided to invest 2,500 INR budget that I had in IEMs instead of buying new TWS Buds.
The KZ Castor I am using doesn't sound as good as the Fiio ones. Obviously the price difference is of around 2k INR so it was set to happen.
But this is still better than my CMF Buds Pro so I think I will stick to it till it breaks. Then buy Fiio ones.
Bass is superbbb
Vocal clarity is great
highs are smooth
what else you need for ₹1500.
I didn't tried Lossess and using simple OnePlus dac still sound quality is excellent. i think for regular Listers its best under 2k nearest competitor is Tanzu waner sg which have even better vocals but castor is all round package
Hey there, thank you for the great review and ratings! So delighted that you are loving your purchase. Hope you had a comfortable shopping experience. Cheers!
I bought this for a friend. I felt these are a little heavier on the lows than my KZ-ZEX. I'll recommend this if you like listening to more bass songs.
Hey there,
We really appreciate the genuine feedback! Your review will definitely help fellow audiophiles to make an informed decision.
