update: im breaking in the 9700.
Initial impression: sounds bright and clear. more difficult to get a good seal for bass but its there. just not easy to seal like i said. cant say im completely sold on these yet but the 3580/3590's are a win for sure. i have them running over night to help get these burned in sooner. easier to get a nice seal with stock tips.
for these 9700, i may have to swap the tips for the sony hybrids or the shure ones i have laying around then retest...
