Finally had a chance to run this sweep. I felt like I'm at the doctor's office, getting hearing exam Tried it with wire up over ear and wire down, using Symbio silicone/foam hybrid tips. With ie800s there is definitely no drop from 1k to 3k. But I do hear clearly a peak at 5.4k, then a little drop and a lift to the next peak at 7.9k, a small drop and another lift between 9k-12.2k reaching 12.2k as a peak, and a sharp drop off after 12.5k. From there, I only hear a small blip around 15k. Regarding cable microphonics, not sure if it was in reference to the original ie800, but with ie800s it's hardly noticeable. It's not the "quietest" cable I heard, but it's soft, pliable, no memory effect, and perhaps a faint microphonics with wire down which completely disappears with wire up over the ear. The length of y-split cable section is 9.5". For my average size head it's more than enough for over-ear fit, and I still have room for chin-slider to go up about an inch.
