Thanks for all your inputs, but the "mystery" surrounding the AD700 and/or AD900 will not be solved unless some quantifiable data are provided to allow me or any other potential to know whether they will fit our heads...Please spend 10 seconds of your time and measure your ear to ear measurements and post them here please =/
Also, for those of you guys who so kindly measured the circumference of your head, unfortunately, our head shapes all differ, so just knowing the circumference doesn't let us know how it will fit...Only the ear to ear measurements since that's the way the headphones are worn, from one ear to another =P
