I am looking for desktop headphones that have a different sound than my Sennheiser 650s and narrowed my search to the above. My reading leads me to conclude that they are similar, but I have not listened with either. Their street price is very similar and I am a fan of open phones for home use.
 
If some members have heard both, I am very interested in your experiences and opinions about each from a comfort and listening perspective and which you prefer. 
 
Thanks to all who take the time and make the effort to assist me.

I'm also interested in hearing opinions on the differences between these two.

"Quick comparison is that Q701 is warmer/darker sounding, punchier, and has more body.  Q701s have punchier bass (Q701 can actually produce deep sub-bass pretty good).  AD900 is lighter, leaner and air-er sounding.  AD900 has more emphasis on upper mids/highs. 
 
Q701s sound more "natural" to me.  AD900s are very easily driven, but I don't find the Q701s to be as stubborn as everyone was claiming the K70x to be.  Soundstage is large on both, although I find the Q's to have a taller soundstage.   The Q701s sound like they have more separation, and I think this is in part because they have a less "air" (high frequencies) connecting the sounds to each other.  So sounds get outlined more with greater separation and are suspended around you. 
 
I found the AD900s to be a little congested sounding in the mids : \  Maybe it's that peak at 4khz on the graph..."

I prefer the Q701.  AD900 sounds too similar to the AD700 (AD700s can be practically EQ-ed to sound the same).
 
AD900 headband is more comfortable than the stock Q701 headband.  I have a cheap walmart seatbelt pad wrapped around the Q701 headband right now and it doesn't bother me anymore.  The ADxxx pads make my head itch a bit, Q701s don't and are a little deeper (my ears touch the drivers on AD900 which are more shallow than AD700).
