Tiandirenhe is a brand that consists of a small group of engineers who specialize in developing high-quality In-ear monitors (IEMs), upgrade cables, portable DAC and AMP, audio adapters, and earpads for headphones. They strive to offer audiophiles and casual listeners alike a range of affordable and innovative products that deliver outstanding sound quality and listening experience.
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.
Best in the class
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...
1. 70mW ample power. For a typical 32Ohm IEM, the volume gets loud at 50% itself.
2. LED is always on. Unplug when not in use.
3. You can change the bit depth and sampling rate while using PC to a max of 32-bit 384kHz.
with this DAC the sound quality is signifant improvment can be seen with KZ Zsn pro2 and sony xb75 earphones. I have also used for office calls and the noise is totally reduced. with this DAC and the sound is amplified too. I dont see HiRes certification but this DAC is certainly superb. The case is also good for carrying IEM. I only worried if cable gets cut, wish it was L-Shaped.
Nice sound quality, giving you nice details in sound specially highs, excellent while you listen melodies.

Good
Very prompt response
It's very good very energetic sound
Audio quality is too good
The fitting and impact of sound quality and comfort is amazing I would love to buy more this kind of eartips
Most 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
