I don't know what the 3300's are. but I've got the 3500's and they are pure awesomeness.
The bass is a little too much, have to turn down the bass in windows...first time ever !! LOL
but yea, the highs come out really well too...the mids are a little twoo weak. would have been nice to have a stronger midrange driver...but I'm quite happy with it...
