Maybe hooked up to an iPhone or low powered source, but certainly not hooked up to my Asgard 2. The bass is much better, and they're a bit less peaky and overall are less fatiguing. In terms of comfort the K712 mops the deck compared to Q701
I've never heard from one person who claimed they couldn't tell the difference between the two. Not to be a jerk, but if they can't I would take all their reviews with a huge grain of salt. Sorry!
You could probably get them to sound similar if both (or just one) was under-driven.
I also agree the K712 is more comfortable (not due to headband only). I'm glad K712 finally figured a way to have their memory foams NOT go flat like they do on the old Annie.
Believe it or not I found the K712 to sound more like a K702 with memory foam pads. That's NOT a bad thing.
The modded Q701 I have had smoother upper mids than the K712(!!).
I never understood this idea that the K712 smoothed over harsh material with upper mid peaks and lots of treble.
I would even go so far as saying the K712 has more treble than the modded Q701.
You should bass mod the Q701. When you do that they're extremely similar. The K712 still has very slightly more fuller low mids. I hope you have some amazing hearing because it's subtle.
IF I didn't have a modded Q701 I might have upgraded to the K712 (maybe). I probably would compare both the stock Q701 and K712 for a month and sell the loser.
Modded Q701 is such as steal at around $200-$225.
