Yes, it has English language and UI is very easy and works fine. Only has two little bugs:
- When the screen is off and playing music (battery saver mode) and you press some button to turn on the screen, you can listen a click in the music. The manufacturer says that it is because the battery saving mode is exited.
- When music is playing and you want to return to the list of folders, to the root of the SD, by pressing the "back" button, it is as if the DAP is lost and does not represent the list of folders well. Just press "back" again and select the SD card again.
From what I understand the interface is very similar or the same as in other similar DAPs.
Again, this is my complete review (in spanish) about QNGEE X2:
