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
