At least this one is a real looker with its amusing retro design, compared to the junk “high end” from Hifiman, HiSound, s-flo, and the other ripoff manufacturers that put zero effort into their players, just for a quick buck.
This one also uses a real modern quality DAC (a similar Cirrus DAC as used in Echo Indigo sound cards, for example), not some decade old “audiophile” nonsense as found in other players that are targeted at this certain demographic. Still, totally useless on the go, of course.
Colorful/Colorfly seems to be a Chinese joint as well, with a German distributor, but I’m not sure. Seems they usually sell PC graphic cards.
