I currently have Westone 4R and Sennheiser 650's. I am using them with ALO RX Mk3 amp and CLAS.
 
I really do not like the 650's and want a full size cans that are comfortable, great sound, and no ear splitting treble, and good quality base. (Gee isn't this what everyone wants?)
 
Can anyone comment on the the 702's? Also what is the difference with the 701's? 
 
Any other options that you can think of? Are the V Moda Crossfade 100 any good?
 
Btw, I mostly listen to rock.
 
Thanks in advance,
Ken

The 701 and 702 sound the same to my ears, but the Q701 has a tiny bit more low end and is a little easier on the ears.  All three of these headphones are known to have some bite in the treble and I would advice you to shy away from them for this reason.
 
A great headphones I think you will like from AKG is the AKG K550.  They are slightly darker sounding than the K701 and Q701, but are much more relaxed in the treble.  I really enjoy the AKG K550 and to me they are an excellent substitute for the awesome Denon AH-D2000.

Why are you not liking the HD650s? They are comfy, have great sound and bass imo. Maybe you don't like the dark (veiled) sound? I own both the K701 and HD650, but the senns are currently my favourite cans.

The 650's sound dead to me. They really lack.

I think you lack an amp powerful enough for the hd650 which makes sense in your case.

The HD-650 is a headphone that sounds its best louder which is one reason I got rid of mine.  To my ears the veil was heard at my nominal listening level and to get the fidelity out of the HD-650 that I wanted I felt the sound pressure was harming my ears.
