I agree, specifically the 3-6k region (6 dB "triangular" cut centered on 4.5k; ref. 500Hz). It's like RE-272 gone wild. On the other hand, the rest is extremely well balanced (with 3 dB dip in 1-2k midrange).
What about that deep fit on GR01? Comply T200 or Ts200 foams? Any other nice long 10mm foams w/ 4mm nozzle?
(I could likely get them made into a silicone custom, but that's super bother.)
The trick is that B2 with its 2mm nozzle allows Comply P Slim - super comfy, better than custom IEMs in fact, and also nicer isolation.
