What was revolutionary last year is quickly becoming standard equipment—both the XS and the XS Max come equipped with a sensor array for Apple's fancy Face ID technology.

Time to fish out the noisemakers! The Taptic engine and loudspeaker come out in an assembly, but easily separate for modular replacement.

The XS Max features a slightly beefier set of feedback units, but both Taptic engines follow the same designs of yore.

Speaking of same, the earpiece speaker assemblies match almost identically across the XS and XS Max, with just a bit of extra speaker volume for Max.
