So what are you saying? Because there are cheaper earbuds made by someone else with this feature, Apple _shouldn't_ add it to their earbuds? I'm not sure why that would be the case.
I'm saying as an "incentive" to get to the new version of airpods 5, it's a lame one, since the feature existed in all kinds of cheaper earbuds for years, and Apple should have added it in already, not leave it for the Pro models all this time.
My argument is that adding it makes their product better, so they should add it. And if they add something that makes their product better, that's an incentive to buy it.
