Also you have to spend a lot more for good bluetooth ear buds compared to wired. Like, you can get a pair of KZ ZSN Pros for 20 bucks or so. They sound great, have nice material quality (they got metal bits on em!), good quality cable, great sounding mic... you get the idea. To get bluetooth ear buds that sound just as good you'd probably have to spend like 80 bucks? And they'd be made of plastic and not have the mic quality anywhere near the KZs. It's just so much easier to get good audio quality with a wire.

I do have a pair of Bluetooth headphones and I use them from time to time. I tend to revert to my wired m50x pretty often just out of personal preference

I have some wired headphones for when I am gaming on the computer, but anything else I use Bluetooth earbuds, and I can't imagine going back to wired ones, never getting the cable caught on things is so freeing. They also have active noise canceling and hear thru which both come in real handy on work sites.

Except you’re not limited to the phones hardware and space constraints with USB. You can put the DAC, you know the thing that does that conversion, in the headphone end now, whereas you couldn’t with 3.5mm because you can push power over USB. Meaning you have the ability to get headphones with a much better DAC, which will provide better audio quality.

It also frees up space in the phone for more battery, different radios, and other things.
