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
Good quality
a very well made cable from Dunu with modular plugs and a very secure fastening system (q lock), no microphonics noted, contrary to many reports, usage : Shure se215 + 4.4 plug + Hiby r4 and it really opens up the Shures and the over ear loops are very comfortable too
This is really warm sounding as advertised. Especially vocals are more engaging. The fact that its driven by phone power doesn't affect the sound quality in anyway like in other dacs I have experienced brighter, thin sound or few peaks in upper midrange. If earphones are having good sensitivity then this dac provides good enough power. Although bit bulky build is very good. I'm sure it can withstand frequent drops also. Have not tried the filters and listening to default filter only. One thing I noticed is although on paper power output is good for 32ohm its only good at driving earphones and not headphones. Distortion kicks in when volume is increased even at high gain setting. I'm only guessing current supplying capability for dynamic driver headphones is not sufficient. Tested with 300ohm HD600.
The sound quality is so much better than any other wireless earphones
The quality of wire is superb.
The mic quality is also good.
Length and feel of wire is good. Sound quality with my Tangzu warner is excellent

Have bought this on 17 Aug 2024 and after using it for almost half a year i can surely say this is the best one in this price range...
I like how crisp and clear the audio is, also how good the IEMs respond to EQing, which unlocks a lot whole lot of possibility

Recently bought this after seeing some positive reviews
Fit:
Unlike many reviews which talks about it's fit issue, it's a wonderful fit for me with the stock large size narrow bore tips. I usually go for medium or small size silicone tips but for this one large one fitted well. i guess large size long stem eartips fits well with this iem.
Sound:
Vocals and string instruments sounds forward but never thin or sharp or fatiguing and has a sweet timbre. I guess it's due to its thick note weight and the quality of dynamic driver.
Bass in general is good. But i would prefer little bit more sub bass quantity. Also prefer the bass to be a bit tighter. Not too tight as i am not a fan of too tight bass. Basically here bass decay is slow and i would prefer it to be moderate.
Treble has just enough energy and details but relaxed.
Overall it sounds very nice with a pleasant timbre.
Note that i replaced the stock cable with fiio ls-b 4.4 mm cable.

Great set to start your tip rolling journey!
Got the delivery under 24 hrs.
