I cannot say anything about the Ihifi and the Xduoo, but I can tell you about the CK4+.While I liked the sound very much with the Ath-ESW9. Also there have been some mods for even better sound.If you can avoid it. It has a bad OS. It wont play some high resolution files. No correct tagging. It has only a few buttons for control and those are only okayish quality.Generally it is outdated, you surely have some other options at this pricepoint.
