I don't know if you meant that seriously or ironically. If you meant it seriously...

The same people who have favorite headphones and who need that 3.5mm jack, they are also likely to care about audio quality. I personally have found that Bluetooth headphones insert a certain amount of data compression artifacts into the audio stream, enough to be noticeable. I haven't looked up the specification details, but to my ear, it appears to be something slightly worse than MP3 128kbps compression when I listen that way.

I still find Bluetooth audio and headphones to be useful in many situations. I just know that some folks would consider the removal of the headphone jack a problem because of audio quality issues.
