@Blaze I'm not buying phones that often, but I recently changed to a Nokia G22 (yes, they also have phones with jack), and one of the things that made me decide on that was the jack as well. I got a pair of wireless headsets from work and I can say they're pretty good, but I am still not over the thought that I have one more thing to charge its battery every once in a while. Wired headphones are pretty much okay and I don't see any problem with them that would make me switch (at least right now).
Edit: I almost forgot. I also listen to the (FM) Radio, so I need the wired headsets to be used as an antenna.
