These are my ER-4Ps, I used them pretty regularly over a period of 3-4 years before the right channel gave out on me. These are the old style, red/blue ones. If you hold the right driver's wire a certain way at the resistor pod, the sound comes back on, so I think the weak link is somewhere in the resistor pod. Could be an easy fix for a DIY'er - or maybe you want them for other tinkering purposes!
