Meticulously crafted to adhere to the renowned Harman FR curve, the KZ Castor series stands head and shoulders above flagship models from other brands. Overcoming the inherent challenges of acoustic tuning, these earphones deliver an unparalleled auditory experience.
Dual-Dynamic Brilliance
At the heart of the KZ Castor lies a revolutionary stacked dual-dynamic driver structure. Purposefully designed, one driver dedicates itself to the 20-200Hz range, delivering a seismic bass punch. Simultaneously, the second driver handles mid and high frequencies, ensuring a seamless, interference-free sonic landscape. It's innovation you can hear.
Bass Unleashed: Harman Target with Improved Bass

Boasting a jaw-dropping low-frequency drop of over 10dB in the 40Hz-300Hz range, this version redefines the limits of traditional headphones. Brace yourself for a bass experience that is not just powerful but truly breathtaking.
Tailored Soundscapes: Customizable Audio Profiles
Empowering users with unprecedented control, the KZ Castor comes with professional-grade filters. These enable two-stage adjustments for both low and high frequencies, offering a spectrum of up to 16 personalized audio profiles. Your music, your way.
Comfort Redefined: Ergonomic Design

Striking a harmonious balance between sound quality and comfort, these earphones are equipped with thermoplastic slow rebound memory foam eartips. The result? Exceptional comfort and sound isolation, ensuring you can revel in your music for hours on end.
Engineering Precision: Unmatched Detailing
The KZ Castor achieves a level of precision that defies convention. Utilizing an integrated injection molding process over 10 times more precise than traditional 3D printing, the internal support structure boasts an astonishing precision of approximately 0.01mm. It's not just audio; it's an engineering masterpiece.

OUR HONEST REVIEWS FROM THE CO-FOUNDERS & AUDIOPHILES

from 5114 reviews
The amount you pay for this DAC is absolutely worth it. I'm using it with my PC, and I also have a Fiio KA13. It provides 32-bit 48000Hz audio output, and it's really good. I'm connecting it via a USB-C port and one extension cable (AGARO 3.5mm Aux Male to Female Extension Cable, Gold Plated). There’s no audio loss whatsoever.
The only minor issue is when you use it with a mobile device — the blue light can be a bit annoying. However, that's more of a personal preference. It also makes some noise with certain songs, but that's actually a known issue with the CS46L41 chip. There's no need to worry though; unless you've used a high-end DAC before, this will be more than enough for you.
Bass and clear vocals

Excellent sound quality

After searching internet found this dac which has multiple input options and support 165*2 watts passive speakers and 350 watt passive subwoofer for future extension, tested with all input modes, bluetooth input feels a bit of low quality as it only supports sbc and aac codecs only, however if you want to use mobile via wired, alternative option is to use audiocular d08 cs-pro usb-c to 3.5 mm and 3.5 mm to rca input (cable creation brand). Optical input mode supports PCM (loss less stereo output) and Digital compress audio multichannel only) these are specific to Sony X-80J 65 inches

Thanks a lot Pritam Ji for suggesting me to use a balanced cable with my Moondrop Aria IEMs and thanks a lot for ordering Moondrop Aria filters for me. The Audio Store goes out of the way to serve Indian audiophile community.
The way my IEMs sound with a balanced cable and Shanling UA2 Plus DAC & Amp are unprecedented!
I am grateful Pritam Ji. 🙏🏻

The empathetic support that I got (as a budding audiophile) from Pritam Ji at The Audio Store is unparalleled. I am grateful Pritam Ji. 🙏🏻

Just bought it and started using it with my IFI Zen Stack - feels awesome.
This was a natural pick for me, since I wanted to have a completely balanced setup for my HiFiMan Sundara.
Nothing much to add, if you want an optimal balanced setup without spending too much, then look no further.
Thanks AudioStore for being blazing fast with your delivery. I got it withing 48 hours of placing my order! Kudos.

For my HiFiMan Sundara, this is a nice quality 4.4 mm balanced cable. I am buying this for the second time, since the first one got destroyed by my kids.
If you are looking for a good quality 4.4 mm balanced cable, look no further.
Audio

This product is reached my expectation good purchase good audio signal transmission no noise at all.....thank you the audio store👍
Yes

I have used lots of TWS even high end of Samsung and Oppo worth 10K. But IEM sound signature is great! This is my second IEM. I had KZ-ZEX. It has dual driver with electrostatic. Compare with that MoonDrop Chu 2 is better clear and smooth sound signature even with single driver. I am using with Audiocular DAC cost 750. Just go with MoonDrop Chu 2 if you are music lover. Thanks.
Great packaging and quick delivery
Loved the theme of the store and the support of the customer service for every problem I faced. I would be interested in buying new things from the audio store in future.
