You're right, dark and a bit peaky in the treble, messing up the tone recordings a bit, but it's inevitable trying to explain it. The GR07 MKII is one of the most balanced dynamics though, I'll give it that, perhaps the best dynamic along the EX1000. ER4S is missing bass a bit IMO as well, but beats the GR07 in everything else, orange knowles dampers will help the 4S' bass punch and extension.
Started listening to these MKIIs today, provided by buddy DannyBai.
