I know this is going to sound dumb but....I think the Q701 is still kind of underrated compared to most headphones here.
I think most people think it's just a green clone of the K702 and has no change in it's sound.
BTW someday I need to try the SR-125. It's the poor Grado that seems to be ignored by nearly everyone.
Fingers crossed that it's about 95% similar to the SR-225i, but probably not. I loved the 225i, but disliked the 325i and 325is.
Also..the old HD-580 deserves more attention despite having the HD-600 driver. Sounds better IMO. I guess it's because it's discontinued. Well, duh.
Maybe the HD-580 is getting incredibly rare, but I doubt it.
Lately i've been suggesting people track one down instead of buying the $399(!!!) HD-600. Save yourself $250.
K501 is also very underrated. I miss mine, but once I got my Q701 I felt I didn't need it anymore. I'd take the K501 over the K702, but not the Q701.
