Another great review,
@crabdog and a helpful one because of your uniquely personal solution to the apparent fit problem. May I ask if, with the substitute cable, does the straight connector project from the notch above your tragus almost parallel to the ground? If it does the same might work for me and my small ears, too.
Are the eartips you used in listening to the BA10 your usual wide-bore ones (same with the ZSN and AS10)? You didn't try the Slater mod as Doc did?
Sorry for the pesky questions but I've been taking notes re: ZS10 vs. AS10 vs. BA10. Your review of the BA10 and the those of the 4 others here in Head-fi are consistent as to its uncomfortable, boxy shape, and I have exactly 1 week left to make up my mind for the upcoming 12.12 Sale here.
Btw love the graphs, especially the comparison overlays. Thanks!
