As long as there are wired-only devices that people might want to use, having wireless-only devices as well forces lots of people to have either two headsets or one with a dongle. Somebody else mentioned treadmills at a health club. I'll add airline seats. Also, some environments just aren't that conducive to interference-free wireless listening. Hell, I've had multiple computers that created their own interference between wifi and Bluetooth. When Bluetooth is truly universal, and it's more resistant to interference, and pairing is less of a pain than it is now, then it will be time to get rid of the jack. Until then, this trend is an annoyance. Maybe it's small in the grand scheme of life, but it's enough that any such vendors are automatically on my boycott list.
