These days, I charge my wireless headphones once a week. When I turn them on, they are connected before I have opened the music app. The connection is stable. When I stop playing sound on my phone and start sound on my laptop, they automatically switch to that. Their microphone is perfectly fine for calling people.
But I have hundreds of dollars invested in good-quality wired headphones, plus wired earbuds, and I want to be able to use those with my phone without needing to re-spend that money. Plus, regardless of quality of the product, I'm occasionally a forgetful human. I've actually run out of juice mid-workout with my wireless set. Instead of not having music for the rest of my workout (I like music!), I simply walked over to my bag, pulled out my wired earbuds, and finished up.
Not having the ability to do that is a deal-breaker for me on a phone, and it's not something that can be fixed by improving the Bluetooth tech. While this is obviously anecdotal, I don't imagine I'm the only person who feels this way.
The dongle is small enough to leave attached to your headphones and costs $9. It would be wasteful to include one with the phone, as most would be unused. Clearly you'd prefer a built-in jack, but you have a cheapish option to add this ability.

Why not just swap in a wireless cable?
Some issues I've noticed:
- My tv (flagship LG OLED) always has trouble connecting to the headphones. I usually have to turn them off and then back on again at least once. Macbook and iPhone rarely have trouble connecting. Connecting on Windows has always worked so far.
- When I'm connected to both my Windows laptop and my phone, in a skype conference on the laptop and get a call on my phone, the skype conference is automatically terminated. FOR ALL PARTICIPANTS. That's insane.
- To make the previous point even worse: except for the ringtone, the audio from incoming calls never even goes to the bluetooth headphones. The audio from outgoing calls does, however. This is all on an iPhone SE.
- Sometimes when I listen to music, or watch a video on a Windows machine, my bluetooth headphones will just pause the playback every couple of seconds. This only happens on Windows.
- If your headphones are connected to multiple devices, you have absolutely zero control over what is happening. You might be listening to music on your phone, but some notification from your computer will interrupt your playback even though the computer is set to silent.
I could go on and on and I've only been using bluetooth headphones for a month. There is a LOT of polish missing here. That being said, this could be a great technology and it's not too far off at the moment. There certainly are some advantages over wired headphones as well.
