Operation successful. I used an asymmetrical type cable from my Iaudio accessories pack in black. The two sides were better defined.
The hard part is actually taking apart the earbuds, which will have a couple pieces crack or break on their way out. Most likely when Etymotic recables these things, they replace the white portions anyhow.
Step 1: Slide the heat shrink off the bud to the canal side. This is reusable and has a cutout for indexing with the wire.
Step 2: Using an eyeglass screwdriver, drive in between the clear and the white pieces from the canal side. You will see what I mean. They are tabbed and glued and will take some wiggling to remove on an axis. You will crack and perhaps even break a piece of this, but it's still reusable. The glue is soft, so you can lever it out. Slide down cable and note how it enters the housing, including the knot. You will most likely have to bore the wire hole larger, as I did to slip the new one through. On the right side bud, look closely and you will see the white piece is broken.
Step 3: Use a jig, such as pliers to hold the earbud on a surface, index it so you know which side the polarities are on. The wire is ever so slightly different and I'm color vision deficient, so I think I got it. The solder terminals are on a flexible paper. You need a pencil point iron and they desolder and solder within a couple seconds.
Step 4: Knot the wire as close to the terminals as possible and shove it in the crevice. Put the white keeper portion on. I didn't replace the glue for future repair. Slide heat shrink back on, then use.
This method is a hell of a lot more feasible than replacing the plug. Unfortunately, I didn't take pics, but the operation really is exactly what I described above. The first side took some time, and I was referring back and forth to the second untouched one for orientation. The second one took less than ten minutes.
I am more than willing to help this operation for anyone else interested. I'm also in NY, as I see this forum seems to be based around. I'm more than happy to help. Etymotic er6 series can be recabled very easily by the consumer, perhaps for the cost of a sacrificial pair of headphones and about twenty minutes.
Now I'll have a pair of Shure E2c's to go along with these. Now what I do miss with these earphones compared to my old Sony pre-ear canal phones was the bass response and certain portions of the mid range being more pronounced. The Sony bass is utterly obnoxious, but can be controlled with my BBE and Mach3 Bass settings. The er6i's are pretty lacking in the bass dept, but the rest of the music is crystal clear, and more balanced without an obnoxious intrusion of mids every so often. Don't forget the isolation.
