Ok, so the headphones are popped in, good stuff, easy enough. But dangit I've got this cable hanging out of it all the time. What if I don't want to use it?

At least they're way better than this crap I had in there before.

There it is all nice and shoved in there, it's not quite sitting right, I can feel it on my ear a bit, and this might get annoying or painful after awhile. I think I can fix that though.

Guess I'll pull it apart and see what I can do.

Well, it is significantly larger than what I had in there. I could take the backing off, but I'd probably lose a lot of frequency response out of them. Assuming that it at least acts a bit like an enclosure/baffle.

I see, theres a lot of extra plastic molded on past the stitching on the cheekpad, and this is pushing down on the speaker and making the cheekpad push out. I trimmed these back all the way to the stitching, and everything fit more snugly.

Still stuck with that cable hanging out all the time. I know... Grab your soldering iron, because we're going splicing! Heres the supplies I picked up.

So heres an almost complete installation. I wired the female jack into the lid right to the speakers, then made a cable out of these current headphones, and my old crappy ones, with two male ends. Get the picture now?

Pretty much all set, and shows the final install. So when I want, I plug in the cable, and away I go. Not in the mood for music or just carrying the lid around? Unplug it! I just zip-tied the plug to a small elastic strap found at that location. Sure it's not going to stand being pulled on roughly, but it keeps it relatively in place.
