I have purchased a C0257 and when ı play music from USB card it sound awful but when I play same song from android phone via bluetooth connection it is louder and has more sound quality. The quality of music from USB drive is intolerably bad. Is it because of equalizer settings? and is it possible to change default equalizer with another app?Statistics: Posted by sansibar — Mon Apr 25, 2016 5:56 pm
