So it turns out the sound in my right re-400 driver was just the cable messing about, as it seems is pretty common with this IEM. But now the right cable housing has come completely off http://i.imgur.com/15GLrN4.jpg Most likely due to me wearing them over ear style with comply foam tips. I must have been to rough when rolling the tips into a cylinder. Any idea how to fix this? I really don't want to return them to hifiman as they took 4 weeks to ship to Ireland and the return shipping would cost me money I don't have atm.
They likely just use a strong bonding adhesive of some sort. Does the strain relief fit relatively easily back into the hole on the driver housing? My recommendation would be to use some Epoxy which should be available at any craft or hardware store. Just put a tiny bit around the upper tip of the strain relief then push it back into place. Epoxy takes about 5-10 minutes to set where it completely hardens and then 24 hours or so to fully cure.
