Two separate models from Huawei have swipe volume controls (freearc and freeclip). I’m not a earbud guru but my $25 anker buds have tap to hold volume controls (not swipe, I’m sure Apple is being specific for a reason), but no matter how you move the goalposts it’s a ridiculous claim.
They all have the squishy silicone part that goes in your ear. The claim on the apple page is it's for the ones that don't have that. Which is true.
It's not a particularly crazy innovation but the statement is true.
can confirm my Huawei Freebud 4 have swipe volume controls, anc and do not have silicone tip. Which is one of the reasons I got them after my Gen 1 Airpods started to annoy me on Android.
