You never know and you should never assume. Dangerous things can occur when electricity is involved...eh?
I don't know the mechanical or technical proficiency of everyone in these forums and should not assume or take for granted I know so. Nor should you or anyone else.
Well...This is talking about rewiring the headphone cable, after all. As in, cutting the cable of the headphones, and reconnecting them in another way to the jack. Unless you somehow miss and accidentially solder your headphones to the power supply, there really isn't much that could happen apart from a bad connection
Another thought, though: Making a little adapter ought to be easier, less risk to the phones and cheaper than buying a new set of phones. As in, a TRRS plug, a TRRS jack and four short strands of cable.
I do know that a pandora has an exceptionally high power headphone output at 150mW per channel. A quick google says that we're probably talking about absolute 1.5volts tops.
Yeah, I don't see how you could electrocute yourself via an amplified headphone socket, but then I've learned to never overestimate the technical proficience of some people around here, and the ability to foul things up in quite creatively unexpected ways
For me, this is the most exciting time in terms of Pandora development since I've had my own Pandora in my hands. Between DraStic, interesting things happening with the DSP, TV out cables, c4a, and the sheer amount of new and updated software that keeps getting released. It's a good time to be a Pandora owner for sure!
Edit: Not forgetting the work on OpenGL and WINE, which I've not tried out yet, but looks very exciting.
