Well there are good and bad headphones no matter if they are closed or open.
I'm not in any kind a professional to say which is best (and only had one real closed one, the rest i have are in-hear portable phones).
But the closed one I had from sennheiser aviation was the best headphone I ever owned till nowaday, and they actually sounded powerful and natural to me. (I remember the good old days of Nirvana on the Amplifier). However they didn't last long back then on the huge amplifier at high volumes.
But for example my Turtle beach aren't anything closed, and they sound like you have a can in your hears (very strange bass frequency, and a huge loud strange frequency like way too much 200-500hz, everything sound artificial).
