Thanks for all the responses, guys.
1) On my ears, the AE is circumaural. My ears are smallish, but by no means miniscule. This probably affects your opinion on the AE radically as it will reduce leak bigtime if it completely surrounds your ears.
2) There are members on this forum who will chant "death to Bose" while ignoring any other facts, and I think that's a shame.
Look guys, I get it-- the average consumer thinks there are only two types of headphones: buds that comes with iPods and Bose ("the best!"). I realize that part of the fun of Head Fi is being alternative by liking Grados etc and reveling in obscurantism. I sympathize and understand. Honestly I was being a bit of a pain in the ass to prove a point about this forum.
3)
Not everyone wants ****ing IEMS It if did I wouldn't have posed the question as I did. They can be uncomfortable and my ear holes are too small for them.
4) the V6 is a classic but that 3m coiled cord will make your pocket bulge walking around town with that iPod. Not portable enough.
5) the Panasonic RP-HTX7 is a loose contender although I suspect leaks more and yes, doesn't sound as good as the AE.
6) Yes, the AE is far from perfect. I wish it were sturdier and had better sound. But even after this thread I have yet to find a can that beats it for my needs. The Denon 1000 seems as close as I can get.
7) Speaking of sound, I realize this is Head Fi, haven of not only audiophiles but dedicated and opinionated audiophiles, but
sound isn't everything in a portable headphone. I am willing to forego hearing the violinist shuffle his feet in a recording of Beethoven's Ninth when what I need above all is a light, comfortable, zero-leak portable.
8) Finally, despite numerous "you'd be better off leaving Head Fi" warnings, I enjoy the forum immensely. Thanks again for the responses.
