I think the iPhone isn't the only possible comparison here. Sure, the iPhone blew minds, but what about the iPad? Apple Watch? Airpods? Apple TV? None of these are bad devices (in fact, they're all pretty solid) - they're just niche devices and limited in the way the iPhone wasn't/isn't. I'd expect the headset to be similar.
