Lucky you ! got my blue XS Max Sheath today and the speaker cutouts were not correct. Very disappointing after I wrote them and specifically asked if they had the proper cut outs and got the response below.
Thanks for reaching out! Glad you're so excited about the Sheath.
That issue has been resolved on both the XS and XS Max, so your case should be correct. But here's some background on the symmetrical cutouts in case you're interested: In order to have products available simultaneous with the launch of the new iPhones, we have to start our tooling process many months in advance. This time the schematics for the new iPhones seemed to indicate that the speaker holes on the new iPhones would indeed be asymmetrical. It was definitely a head scratcher, as that sort of thing didn't seem very Apple-like for a company that obsesses over details the way they do. But, since Apple doesn't release any details prior to launch, there was no way to confirm this ahead of time. And so there was a raging debate behind the scenes among people in the industry as to how to address this. The sensible solution was to do what we - and pretty much almost everyone else - did, which was to use symmetrical cutouts. Going with asymmetrical cutouts would've meant that, in the event that the holes on the new iPhones ended up being symmetrical, our products would be covering some of the speaker holes. Going symmetrical ensures that no functionality is blocked. And in this particular case, it also leaves the antenna band covered which may or may not help improve reception to some small degree.
Congrats if you've gotten this far!

We love when customers do their homework and care about the details, so there's no such thing as TOO SERIOUSLY in our opinion - ha! Let us know what you end up thinking of it!
