Sure they are 7506s ? I can't imagine mine being described as lacking in
bass (any more might be totally unrealistic), or non-fatiguing to listen to
(unless upper mid-deaf already !) .....

Perhaps I should clarify:

There's more bass than you need for critical listening, but for DJ use you
(or at least *I*) probably want something with even more hyped low
bass to make cue track beats audible over a slamming PA subwoofer.
Better isolation is helpful, too, but you get so much low bass bleed from
bone conduction that sometimes you just need something that can
work like a bass shaker for your cranium.

As far as fatigue, I mostly mean in the comfort sense. I don't usually
drive headphones to a high enough level to cause any kind of hearing
fatigue, nor do I use them for critical listening -- they're mostly a
head-mounted "do not disturb" sign. :-)
