I thank you for the effort and demo. Too bad those tiny tweeters sound so poor... I'm betting it will sound "great" with a decent AMP and speakers! I have NO idea how the mfg. claims 50 WATTS via a 5V low current USB cable?? Some things remain a mystery. I ordered 2 anyway.
A "ratty" sound "remains ratty" ~ just at higher volumes! His speakers appear to be "tweeters" designed for mostly high frequencies and I think THAT is the problem.

yes the quality is great for the money i made a radio with that you can see it on this link ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2is86XwhTUI.html
the display shows that everything works, the blue tut is registered on the mobile phone, but there is no sound on the headphones, the headphones are checked, an amplifier should be connected for the speakers, but for the headphones you should not ,,
