I have the Sony Xb40 and only certain songs sound good on it. If there is a song with any sort of louder bass or Ben middle of the road bass it sounds horrible like scratchy and blown but I just got it yesterday. It’s not like I’m blasting it either it’s only at half volume or less and for a speaker that’s meant for bass it doesn’t do too well with it... I have the same earbuds as it and it sound great on every song I’m wondering if mine is just a factory default like I got a bad one or something
