K702 AE and Q701 are 99.9% the same IF YOU use the same pads. The AE was a hint warmer (like a miniscule amount of a HINT), but without a side by side comparison (which I did), you wouldn't know which is which based on sound alone, IF THEY USE THE SAME PADS. The pad differences are what makes the AE and Q701 sound like two different headphones. So owning both pads effectively gives you both headphones.
If you have the Q701, buy some AE pads = basically instant Annie, but with headband bumps.
Following that logic the Q701 must then be the same as the K701/2 as the annie edition only has different pads and. Cosmetics...
Correct me if I am wrong.
