I'd argue not to sell more AirPods, I mean sure it's a great extra bonus, but what is the other option you would prefer? that they cover the ears completely like big studio headphones? That they give you a pair of AirPods? Or that they make tethered AirPods? Or Bone Conduction, which means audio quality typically plummets and complicates how the device rests on the cheekbones.

All of those are various compromises that also suck for various reasons.

What about people with hearing issues? Most of these alternatives are terrible for people that wear hearing aids.
