Looks like I'm in luck:
These sound great. Punches way above $30, and does it with some nice clarity. Once you tame the midbass hump and fix a few peaks in the highs, they really are exceptional.
Thanks for indicating that something is out-of-bounds and needs taming.
As my first in-ear, I recently got the HSS F420 Quadbeat and was quite disappointed in the wide, cartoonish hump centered in the upper-bass. It dominates everything and makes a muddled mess, even managing to wipe out the low-mid-bass and low-bass. It certainly sounds like it looks below 1000hz: http://en.goldenears.net/15834
The quadbeat-2 seems to have an even more emphasized hump in the same region (http://en.goldenears.net/21721), which doesn't make me think it's moving in the right direction. Yes, it's all correctable with judicious EQ or inverse-filter design.
It seems, from the measurements, that many/most in-ears have a crazy bass/lower-midrange emphasis which makes me think that maybe in-ears aren't for me. (Unless I'm willing to put in the EQ work or spend big bucks for monitor-quality or customs.)
