hello Sashoir - have you found the solution. I received my Soncoz few days back and started having sound glitches issues. Mine is powered with Apple iphone adaptor 5v/1amp
Dear Alekksander, thank you for your reply. I don't believe the interruptions I've experienced are interference-based (though I could be wrong).
There may be something "wrong" with my AC power supply (though I very much doubt it) or my AC/DC adaptors (also doubtful, but slightly less so), but my best hypothesis is loose connections.
I have had some other problems (such as power on but no input able to be selected), so I'd not be astonished at QC issues in the manufacturing process.
