It's funny that Best Buy's best selling Apple product is something that restores a feature that Apple removed, and it has a
rating of 1.5 stars out of 5 on Apple's own website. People are clearly not happy about the removal of the jack, nor are they happy with the adapter that's meant to restore the function.
If you want to listen to music in your car, chances are you don't have Bluetooth and it's not like you're going to buy a new car just because of Apple's stupid decision. So you use an AUX cable like normal people and for that you need a headphone jack. If you just bought the car, then it's likely that in 10 years you'll still have the same car, so even in 10 years, you'll still need a headphone jack.
Wireless headphones are nice, but wired headphones aren't going away because the best headphones, used by audio technicians, are going to stay wired for a long time. Audio recorders don't come with Bluetooth. And having to buy wired AND wireless headphones is unnecessarily expensive.
Floppies went away and were replaced by CDs, which were replaced by internet downloads. But floppies, CDs and the internet were only used by computers at the time, so it was an easier transition. Headphone jacks are used by computers, phones, music players, cars, audio recorders, audio interfaces, microphones, cameras, and many more devices. Therefore, wireless headphones aren't a direct replacement to wired headphones. They are a new product that exist in parallel, and this isn't going to change for a long time. I don't see DJs and audio technicians buying new equipment just for this, nor do I see Sound Devices or Zoom releasing recorders with Bluetooth in their high end products any time soon.
