Hey! I'm selling my ER4S, I have the original case as well as 2 pairs of unused tri flange tips, and 4 extra filters, along with the filter changing tool. I'll ship them with my current tri flanges on as well, you can choose to discard those or clean them depending how much germs bother you :P The small etymotic zipper pouch will be included as well. These have a couple hundred hours of burn in I would guess. No issues with the build quality or signs that they will break anytime soon.
I put $175 because I'm not sure what these go for, I saw the ER4P on Amazon for $237, thought this was a good guess. PM me!
