I am looking forward to your review. I am considering the same units.

Hi All!

OK.. our supplier offered to send us both, try for up to 30 days, send
back the one you don't want!

Well... they both arrived yesterday..

Both - obviously very high quality..

Both with good cases..

Bose, more detailed manual.. DC, - good but brief..

DC - cell phone input that REALLY works nice, music input that auto
mutes.

Both comfortable, the same weight, DC has 1 extra articulation point
that allows it to fold very compactly, and the headband distributes
pressure better.

DC appears more rugged, articulated joints are (appear) stronger..

For my head, I would give the comfort edge to the DC..

Not sure about the value of the "FREE" music system offered with the
Bose. I sure don't need it, and it is not a terribly impressive
unit....

..and there is no way to use it with the headset.. so why... ?

So now we are going to "fly" them...

Chapter 2 when I get the 1st impressions from my partner, chapter 3
after we fly them....

Cheers!
