Well I wouldn't call it a basshead headphone but rather an audiophile headphone with really great bass quality and quantity. After burn-in, the bass sounds really natural with just about any kind of music I've played and is one of my favorite things about it, even though I'm a mids lover at heart. It has really visceral slam and just the right amount of decay. It really digs deep within the sub bass region and gives that extra atmospheric feel for certain tracks.
I'm honestly not disappointed at all that you didn't purchase my pair since I'm super reluctant to let them go in the first place haha. Means more time for me to enjoy them before they leave.
