I have a pair of e-3's that have sat unused since I purchased the e-5 model.
They were used for two weeks, and are in "like" new condition with all original packaging and materials. I only used the foam tips, and have replaced them with new ones from shure.
I also have new in package tri-flange tips, and additional new foamies that I will offer as an option at additional cost.
