Hello guys I wanted to buy some really nice headphones. I am pretty stingy and thought about it a lot. After some time i decided for the Sennheiser HD 4.40 BT (I own a Samsung s8 and it needed to be compatible with that). But today when they arrived i used the cable to listen to some music and what i heard was completly horrific. The sound was completly off and there was a lot of strange noise. I got no clue about headphones and how they work, I always read it has a nice bass but shouldn't normal pop music also be reflected pretty nice? I read on an amazon questione that you need to cofigure it, does someone know how to do that? Thanks for your help!
