Well as per title,

I own a marshal monitor 2 anc. But whenever I connect through bluetooth to a pc the sound is terrible - as if the whole bass channel is removed. I've reconnected using the given cable and sound is indeed beautiful and full that way. But with just bluetooth it's as if the sound is "squeezed" and I hear no bass. Even worse than my cheap 2 dollar earplugs.

I am using a pc btw, I don't do mobile phones.
