I blindly followed this guide with my HD 515's and ended up with sound in just one ear. After investigating, I realized that the cable is assembled differently for my model (and possibly all 5xx-models).

In my case the mapping was this:
Red = right
White = left
and
blue and black = ground.

Just wanted to share.

the wire had gotten pinched in the pivot part of the headphones so I cut out the damaged part out.
the cable between ears is made up of 16 very fine wires – 8 red and 8 copper. they are not separated and I assume only shielded from a coating on each strand(?). It took some time (and a magnifying glass) but I got them separated, tinned, taped so they wouldn’t short, and somehow got all that into the little slot that hides/protects the wire. The pad went back on pretty easily by slipping on about 1/4 of it and then rotating it (like putting a chain back on a bike) – tucked in the rest – plugged them into my NEW Zoom H4n – back in business!!
thanks again!

Fantastic! Did you get yours working again? I’m listening to mine right now, and noticed that if I jiggle the connector I can still make the one channel die – I guess my soldering job wasn’t as good as I though! But they sounds fantastic once more.

perfect! thanks! I’m glad I didn’t force that plastic cover off!
Found a weak spot in the wire on the right side.

To expose the little splitter panel, I pulled off the padding from the side with the cable running into it, and that exposes two screws. Once you’ve unscrewed these, that side of the headphones pops open to reveal the internal wiring.

Pulling the padding off was not too hard, you just work from once side. Putting it back on was a little harder, but I got it back about half-way just by aligning and sliding the plastic back into the earpiece, and then ran a little stick along the edge of the rest of the open part, forcing the plastic to flip over the side. with some moving around of the padding it all slipped back into place.

okay – so how do you get the cover off to expose the little splitter board?

That is a huge coincidence… Good luck with that, does those cans also come with the 4-wire core?

That’s so funny that you should post about this right now, as I am just in the midst of doing the same thing with my Etymotic ER6is…
