from 5180 reviewsMost convenient

This was a gift for a friend of mine. The shipping took some time but when it reached them it was shipped the same day and after two days it was received. It came in perfect condition. I'll copy my friend's review below:
"This is most balanced IEM with a touch of warmth among everything out there. The Bass is just a bit much and with a 3db high-pass filter it became perfect. It doesn't get much better from this. The soundstage and imaging is decent and competes with +800$ stuff. The tuning, resolution and timbre is one of the best even under 2k. I'm very much in love with them. The comfort is pretty decent. I haven't got tired of them even after long hours."
The audio quality is very crisp and refreshing
The sound just amplified after using this with my kz castor pro IEMs....it is amazing.

Great product, strong magnet and holds the DAC snugly. Wish the 3M sticker was sold separately as well as already started to come off (user error).
the Detailed and balanced sound. then the design is so beautiful, the white version looks very good.
*What I liked the most:*
Clear sound at a volumes.
Good bass response, with focus on the sub-bass.
Tuning nozzles which make huge difference to the sound signature.
Good treble which is not harsh or sibilance.
Good soundstage & imaging performance.
Generous amount of ear tips to choose from.
High quality cable.
*Something that I didn't really like:*
Huge metal carrying case.
Ldac, hifi eq, durability, water proof rating
Quality

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 options 1. connect using Portronics Bridge Y USB 3.0 to Type C OTG Adaptor via USB A. 2. 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 inch

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. 🙏🏻
