Seems to work well with sensitive phones, no hiss with anything in my collection.
Did find myself switching beats audio off, as the bass was too much, needed when using the speakers which have excellent sq and are loud.
Usb otg works well, accepts my sandisk extreme drive, and even my fiio e7 outputs from usb both video and audio.
Audio playback is impressive, especially in eq mode where it'll try to access gracenote and play lyrics alongside,
As well as update any music or album info.
