have this "miracle part" a few days in use and can only say good things ...
For its size / power almost madness ... it's just fun ... have tested it on multiple devices and connections ... where he achieved the best result with cable (Bluetooth it sounds "sharp"). Less it is suitable for the "background music", he is always in the foreground.
Sound:
Full, clear, not tinny, already acceptable for its volume bass. (Better than the dull B ...). If you placed it in a corner of the room (about 20cm from the corner), the "bass" improved. Also, the level is quite within its power rating.
Comment:
I do not know what so many of such devices expected ... frequency response below 30Hz ??? (Or even 20 Hz) with sound pressure levels beyond the 110dB mark ??? Questionable ....
in this sense, absolute buy recommendation ...
