Perhaps it was we who were not so clear about this, so apologies to
@Dsnuts . In various studies on ear anatomy, it's true that there's no clear statistical correlation between the absolute size and depth of the concha and the external acoustic meatus, relative to race. There is some correlation with respect to gender, but these differences have not been fully fleshed out. However, from empirical observation, we noticed a clear predilection for larger size ear tips at our US and European audio shows, compared to the spread at Asian audio shows. Thus, our design philosophy has simply been to design to be as compact as possible, so that our products fit as many ears as possible. Specifically regarding LUNA, we've noticed a consistent trend of people opting for one size larger than what they usually use, so much so that we had to borrow the new extra large size SpinFits from the booth next door, and this may be specific to the fit that LUNA's particular shape requires. However, with our new products, which are all-BA based, future multi-BA offerings may make it impossible for us to make things as compact as they are on the LUNA, though we will always try to make our products as small as possible.
