In very good condition! Comes with original hard box, eartips (1x Gliders, S Tri-flange, 1x M/L Tri-flange, 1x and 2x foams), filter changing tool, 6.5mm adapter, manual, shirt clip (for microphonics), and the ER4S of course! These are my FAVORITE set of iems. Even 20+ years later, these legends live on. Known for their superb accuracy/neutrality (92% accuracy). EVERY part of the frequency response is simply amazing. The highs are very sharp, but just enough so that it is not sibilant. The vocals and midrange are very clear and articulate. The only complaint people have is the bass quantity, but the quality is there. I'm only selling these because I need some money at the moment.
