I still refuse to jump to wireless headphones/earphones. It's partly a matter of convenience, more on which I'll get to, and it's also a matter of audio quality. I'm not at all a fan of removing the 3.5mm jack, although I recognize why manufacturers like Apple, Samsung, etc are making the switch.
From a convenience standpoint, I can only stay on top of the charge state of so many battery-powered devices. Between my laptop, my cell phone, and my personal audio player, that's all I can manage. So my mice, earphones, headphones - essentially all accessories, are wired.
When traveling, I acknowledge that it would be nice not to have the wires hanging out all over the place, but I'll take that over the feeling of dismay when I pull them out to use them and find they've lost charge and are therefore temporarily unusable.
So, at home I have various DACs set up and various wired, transducer solutions. A Dragonfly is on my office desktop, wired to a pair of Bose desktop speakers, or I switch to a pair of wired GN2000s for my conferences and audio when I need to keep the noise down.
For mobile calls, I have a Pixel 2 which has no 3.5mm jack, so I have the obligatory adapter that @Dracula shows above (but with a mic band), and a generic $9.95 headset I bought at an airport. I tend to lose those and/or they inevitably fail 1 day past the warranty date, so I view them, essentially, as a throwaway solution.
For my portable audio setup, I have an Astell & Kern Kann with a 2.5mm balanced output, and a set of custom JH Audio Lolas running over a custom Black Dragon cable, which I treasure. There are no wireless headphones/earbuds that I'm aware of that can deliver the liquid audio experience of a set of Lolas.
