Regarding highs, I think the reason we all perceive them so uniquely is that these are frequencies most affected by ear canal shape and geometry. So with headphones, the standing waves and modalities for resonances are all at slightly different frequencies for different people's ears. It's a good sound-science topic, maybe when I have some time....
It is a good sound science topic! That would explain a bunch of things - why I heard as a child and occasionally still hear a high pitched drone in some large stores (like old warehouse appliance stores) that I'm pretty sure came from the HVAC systems, and why at 54, I am still quite sensitive to high frequency sounds, and still have quite acute hearing of the upper registers (up to 18k pretty well and 20K at least to the point of knowing that there is sound and energy there via sound generator apps for the iPhone - admittedly suspect...). It would also explain why my very strongly preferred sound signature is that of the Mad Dogs, HD650's, D7000's, shure SE530 and other slightly "darker" (I am beginning to hate that term, as it is so often perceived negatively) headphones with smooth, detailed highs, but without the bright, brittle, shrillness (to me) that others greatly prefer - Ultrasone and Grado - I am looking directly at you, and Beyer, you get at least a sideways glance...
To bring it back full circle, I am in Denver for the annual National Down Syndrome Congress Conference (say that 5 times real fast) without my Mad Dogs, and I'm jonesin' for them big time! I do have my 1964 Ears Quads (CIEMS that are really similar to the D7000's) so that helps a bit. Mostly I have my lovely wife and beautiful 8 year old daughter. Neither let me wear headphones much on a trip like this.
Oh, EDIT - I use these at work (industrial equipment repair facility - loud machine shop). Not that great for music, they roll the top end way off.
