For some reason the headphones that came with my Roku 2 no longer work.
I tried several other pairs of one (no Roku) and they don't work either.
Neither do the headphone volume buttons work any more.
I have looked at the available accessories and don't see a remote that would work with my model.
How/where can I purchase a new remote with a headphone jack that works with my model?
I'm looking for the same thing...did you have any luck?
The only current Roku remote sold with headphone jack is Voice Pro with rechargeable batteries:
