I thought failure occured from crack in the case and eventually having wire cut because of the soft shell flexibility. But clearly, I seem to be part of that group with oil that sips in from heat /sweat. I really want to go back to silicone iems but 2 years is a little short life for 1kUSD+. Using anti moisture bags would help slow this down then?
GhostWing and arnaud --
It is quite a small percentage, but there are certainly people's whose body chemistry manifests itself in oils much more than cerumen (wax). For these customers, Sensaphonics recommends an aggressive and ongoing program of desiccant use. Standard desiccant canisters are not very effective in some circumstances. We have had reports of success in using the Dry & Store Zephyr electronic desiccant system, though nothing like what I would call documented proof of effectiveness. It is, however, a demonstrably stronger desiccant system. Moisture wicks alone don't seem to win the battle in the long run - at least in stubborn cases. It seems the key is to not let the buildup to start.
BTW, silicone earpieces don't "crack." (Cases of tearing, especially in versions with a permanently attached cable, have occurred.) On a related note, our IEMs have been shown to be more reliable since Sensaphonics began using a coaxial plug-in cable system about a year ago. As part of that, a new gasket system inside the coax connector is designed to minimize the migration of body oils toward the drivers.
It's a vexing problem to those who face it, for silicone and acrylic designs alike. Give us a call if you'd like to discuss your situation directly.
