To all who love to listen to music: Of all the predecessors of this has the best and sharpest sound over headphones.
No noise, no plate, no lack of dynamism and clear. I was amazed at the quality.
As a source I use Spotify then 3,5 jack a Fiio E06 Fujiyama headphone amplifier and a Sennheiser HD515 it.
So my sound desires are virtually satisfied. If anyone experiences with USB OTG soundcards has please report.
At any Smartphone, I recommend the Ergo Direct device protection insurance.
