Precision Tuning Beyond Conventions
Introducing the KZ Castor IEM with Mic, a sonic marvel that transcends industry standards. Available in two exceptional versions - the Harman Target and the Harman Target with Improved Bass - these models redefine sound quality. 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
Crafted for extended listening pleasure, the KZ Castor features a top and bottom-stacked cavity 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.

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.
Good Quality and got a clear case for the player.
Thank you 😊

The quality is great, I felt that the base got a bit reduced and mids and treble enhanced using the same. They look premium. The only downside is that they are slightly bulky as the cable is 16 core and sometimes you can feel it behind the ears. Overall a great cable to upgrade your entry level iems to support balanced output

After going through many websites, I came to know about this particular dac, which is purely oriented on audio amplification with dedicated chip unlike other dacs available under 2k, so ordered and received in two days, to my surprise it has significantly enhanced the audio experience on oneplus 13R, with wired earphones (redmi hi-res of 500 INR), usb type a to c adaptor really came into handy and detected as HiFi audio in my dell laptop, cherry on the cake was the pouch, I didn't expect a pouch, very happy with the purchase...

Visited thier store cum experience center it was very great place for sound lovers . Especially like their display of products in thier demo room.The Owner /Staff were cooperative and also suggested me several IEM's before i select one.

I was looking for IEM Tangzu but they were loud and bass was little low as per my ears.Owner or Associate at store suggested me Audicular i liked the sound as well as bass effect its great product.
The Sennheiser IE 200 delivers impressive value for the price. Comfort-wise, they’re lightweight and fit snugly thanks to the ergonomic design and included foam/silicone tips—great for long listening sessions. Build quality is solid despite the plastic housing, and the detachable braided cable adds durability. As for the sound signature, it’s balanced and clean—tight bass, clear mids, and smooth treble without harshness. Bonus points for the dual-tuning feature that lets you slightly tweak the sound. A fantastic entry-level choice for anyone looking to step into the audiophile world.
There sound is pretty good
