Better audio fidelity
I could no longer use the analog output of my Galaxy S21 as something has gone wrong with the phone's connector. However, I'm more than happy to use this DAC as I can now handle phone calls and listen to music with far more audio fidelity than ever before.Do know that you'll be using more phone battery with this device which is understandable and it does get warm to the touch as evidence of this.

Seemed good at first.
This dongle is a great value if you need a bit more amplification for slightly less sensitive IEMs or closed backs on the go. It doesn't seem to be as clean as an apple dongle or some similar FiiO products.It didn't end up working for me, due to incompatibility with my Pixel 6. Do not buy these to pair with a Pixel. The FiiO KA3 ended up being compatible and I never had trouble with the apple dac dongle. I'm giving it good rating because the incompatibility isn't really 7Hz or Linsoul's fault.

Sorry, it had to go back.... POP
It is a nice little dac/amp. It is built ok, feels well made, only weak link is the attached USB line as it is not replaceable, but for the price understandable. The unit does get hot, I think it is because of the LED light that stays on, which it really does not need to. Should only turn on at the start of use and maybe once every 10 minutes to to keep user informed.The sound was clean and had a good amount of detail and did not sound colored at all. I was happy with the unit for the first 20 minutes and then it began. I was getting a random POP sound every once in a while. I tried on several other sources and with several IEM's and headphones and it was there. Not present on any of my other dac/amps, so this is being returned. I have read that some others are experiencing the same POP sound, so maybe on V2 I will try again.

Works a third of the time
Harldy works and when it does, it has a bunch of audio popping. It is getting worse as time goes on. I regret buying this.

Body is hard aluminum careful on phone screen contact
Great sound and small size. Carefully of hard aluminum sharp edges as can scratch phone screen in pockets. Also light is really bright (cover with sharpie helps). Wish USB was replaceable as seems to have issues once and a while due to tight repeated bends...

Durability
I had no issue with the sound on any of my iems. However the ribbon style connector is not durable. It wore out in a bit over a year of sporadic use. Since it's non-detachable it was rendered unusable. If more durable I could rate it higher
