Disclaimer #1: In my experience, I've come to discover that the term basshead is tossed around very loosely, and (more often than not) carries a negative connotation, when that need not be the case. Where I'm concerned, such terms must be put into context. As I've used it here, the term basshead merely implies a listener who admires (and/or maybe even prefers) a moderate to heavy bass lift. That, of course, says absolutely nothing about the quality of bass, as some of us are far more concerned with quality than others. I believe it's no mystery then...

SEE PROS & CONS.   NOTE: The clamping factor will obviously differ from person to person, but I'm surprised to find little mention of it, as it is the sole reason I'd never think twice about the HM5. Shame, really. Considering they do sound great.   UPDATE: Thank you for the wonderful suggestions, and after some (needed) adjustment, their clamping force is MUCH more tolerable, and plays in their favor considering how well they isolate. As such, I've updated their ratings, and I've only not given them a 5/5 because I don't believe anything is...
