3.5 mm. I hear mention of "standard" 2.5 mm and other than my 1973 and
the Freerunner, I don't think I've ever seen a 2.5 mm used. Most wired
headsets on phones I've purchased in the past each used their own
"proprietary" connector with the exception of my recent Motorolas
which used USB. That means every set of headphones I've EVER used were
3.5 mm (actually, they're labeled as 1/8 inch) and that's what my
Element has as it's AUX input, so I'll stick with that. :)
