The first problem with wireless headphones is; for wireless headphones to sound good, and work well, they not only need good driver engineering; but also a high quality DAC, amp, and Bluetooth receiver built in, along with a good battery. So the overall cost of good wireless headphones is unavoidably higher than wired equivalents.
The second problem is, that most of them have non-replaceable batteries that only last 2-3 years, especially since you can never use them wired thanks to the lack of a jack.
So instead of high end headphones being a long term investment that could last 10+ years, they become an item that has replacement cycle, much like a smartphone.
And every smartphone company making that extra cost (not to mention waste of material), unavoidable with the removal of the headphone jack; is pretty disappointing to be honest.
