which cables for cowon J3 + fiiO e9?

Hi guys, I just got my fiiO e9 amplifier. But I can't get any sound out of it. Right at the moment I'm using a ipod, but next week the cowon J3 will arrive. So could you guys tell me which cables I need to make it work?

I'm now using this cable:

I plug the red and white audio cable in at the back of the fiiO e9, the 3.5mm jack I plug in my ipod.

Then I plug the power cable in and my headphone, but I don't hear anything..

Am I using the right cables? because when I search on the internet I see also this cable:

do they plug the 3.5mm jack in the line-in (on the fiiO) ? (in stead of using the red/white audio cable)

If that's the solution, then my question is still what cable do I need for the cowon J3? (because the J3 has an other plug in than the ipod).

for clarity, this is the back of the fiiO e9:

I hope you guys can help me.

Ok, thanks for your reply, the fiiO didn't came with a 3.5 to 3.5 cable (I believe the e7 does indeed come with that cable). So I guess I have to go to the store for such a cable.
