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.
OK, listened last night...not sure I'm the one to give definitive impressions on this...I never like most of these oddball shaped iem's. My preference is the "bullet" shape, Etymotic, Tenore, others like that. The GR07's have sat around because I have trouble with seal/comfort on them. I played with tips for a bit, settled on some Monster tips. Next, I think my GR07's have some channel imbalence, the L side seemed quieter than it should be (wasn't dead, though). Now, having said that, seemed the 750's KILLED the GR07, more alive, wider, both have detail but really enjoyed listening to the 750's MUCH more, even trying to take all the above into account. GR07's kinda flat, boring in comparison (BE probably meant to fix this to some extent).
