That would help. From reviews the GR07BE has slightly less sibilance and slightly more bass than the original. Can you compare the spaciousness (airy vs intimate), warmth of midrange, and extension on the high and low end.
Thanks for taking the time to answer my inquiry
OK, be happy to, still working on getting a good fit and seal on the 750's, without which the comparison is pretty meaningless. Haven't worn them in a while, but I don't recall loving the fit of the GR07 either (likely why I haven't used them much). I'll try to get all this stuff squared away and do a comparison soon as I can.
