I ordered one of these from Amazon and received it today. There are two versions, one with a USB C power input and a 3.8mm jack (Tiny A) and one with both 4.4mm and 3.8mm jacks (Tiny B). I ordered the black Tiny B version with both jacks.
Sounds great as expected. The Fiio control app can change the EQ and other things. It has plenty of power to drive all the headphones and IEMs I have. Tried it with my phone and all the tablets and Chromebooks I have. Works with all of them. Both the Hiby app and UAPP recognize the DAC and output bit perfect to it.
I'd say it is worth $22. No cable needed.
