Up for sale are my Etymotic ER4XR extended response earphones. These haven't been used much. One pair of large triple-flange tips are slightly discolored from use, but the other set are unused. The box says these came with foam, dual and 3 flange eartips. I don't remember having any dual flange tips for these earphones. I have 2 sets of large triple flange, 2 sets of medium triple flange, 2 sets of grey foam, and I'll include 3 sets of large yellow foam tips. Thanks for looking!
