SOLD!! Gently used Etymotic ER-4P in excellent condition. I am the 2nd owner, the original owner says he only put about 100 hours on it, and hadn't used it in a couple of years. I bought it recently as a replacement for a very old ER-4P (the red/blue/green version), but the new ER-4XR is sufficient as a replacement. Compared the the newer ER-4XR, the 4P is a tab bit louder, and a tad bit cleaner / clearer to my ear.

Comes with everything pictured. The original inner foam holder inside the black plastic case had pretty much disintegrated and was crumbling onto everything, so I pulled it all out and replaced it with some simple white foam sheets. Also included is a 75-ohm adaptor to basically "convert" the 4P to the 4S, which has the higher ohm rating. The Shure "Olive" foam tips on it give even more sound isolation than the Ety tips, and they are new out of the packaging.
