Another good DAC from Fosi

Very affordable, very simple... and does exactly as it needs to. Works really well to my ears. A clean, well-balanced and dynamic sound, free of any background noise at all. The supplied cable was not as shown, and feels a little flimsy, though works perfectly well. Another nicely designed and performing Fosi product.

Cable KO

Hi, DAC came D.O.A. (dead on arrival). I tried on mobile, tablet and PC, nothing worked. Then I changed delivered cable with mine (much thicker and longer!) and then worked everywhere. Sound is amazing!
I will probably order one USB-C cable from Amazon, becuase I can not wait for new delivery, but short cables are rather expencive, about 15 euro...
