Need Recommendations: Denali ANR or Sennheiser HMEC 400 ANR?

Unfortunately, none of the airport shops I have visited carry
either of these headsets in stock. The ANRs they carry -
lightspeeds,DC etc. just didn't cut it for me (for one reason
or another). The lightspeeds did rather
well on the ANR part but the voices sounded distant - this I
really did not like.

After reviewing many specs etc. I am thinking of the
Denali ANR or the Sennheiser HMEC 400. (which I'll have to
web-order)

Anyone had experience with both? Which did you prefer?
Criterea for me are comfort, fatigue (lack of), clarity of sound,
realistic reproduction of voice. (I'm trying to stay in and around
my $600-ish budget).

Any comments, suggestions, advice appreciated.

Thanks so much.
