This is a weird post. Like all headphones and IEMs AirPods are flawed. The question is are the features and benefits worth the cost as compared to like competitors. As far as research goes, Given that they have a ton of pretty niche features that improve the listening experience (consistent sound regardless of fit on the Max, being able to use the AirPod Pro 2s as hearing aids, being able to use both for sound abatement (and have data that shows levels pre and post abatement). I like the headtracking for movies. I think they are doing a tone of research. Just maybe not into what YOU want.
Agree on Siri though, except for setting timers, alarms, and reminders. Though I wish it had the voice and personality of the narrator from Fight Club.
