Then you've picked a spot on headphone for you because these sound just like a movie theatre speaker. And they're not nearly as bass heavy as the Koss Porta Pro. But they're bright too and very detailed in the mids so basically you get lots of clarity and the bass depending on the music can give some growl but imo it's not overly dominant as to be only bass but it's in my opinion that these supply enough bass to let you know it's there which to some is too much but that's subjective. To me apart from the treble spike these are finely balanced, I love them.
I truly couldn't have picked a better headphone for movies or gaming. Period. And for me in music they're fantastic too. But for the money these are a bonafide bargain!
The only issue I have with these is their internal build quality but that's what the warranty is for, I unfortunately had to make use of it but you'll probably be fine.
