how long are memory wire sections on IEM cables supposed to last? - Page 3

If the stock cable that is similar to the Westone cable irritates your ear you might find some relieve by keeping the cable a little looser over your ears, no need to synch it down super tight to your neck and ear. Also are you wearing it under your chin or behind your neck? I find they are more comfortable worn behind the neck then brought around the front under the arm.

40m a day on the day i use them. so about 30/d on avg a week. (hearing aid drying cycle)
WRT to accelerated aging this should also be relevant to drying the actual IEMs. It looks fairly interesting, but without specific data on the tube plastic and IEM acrylic and knowing their expected avg lifespan, I don't know what to think (e.g. for that plastic the site talks about 1h at 40deg is 2 days at room temp, which isn't insignificant but not that bad (although it seems relative humidity varies that too http://www.plastemart.com/upload/Literature/Accelerated-ageing-tests-to-meet-performance-needs-of-plastic-medical-devices.asp )
In any case it's certainly not my specific problem. I've asked the vendor and he said a lot of people are having problems with the stock cables' memory wire in similar timeframes (why the 12m warranty - I don't know)/I should get a custom cable if I want it to last (I won't, screw that. i don't really appreciate the upselling but i suppose that's somewhat honest)


Sorry, meant to say glass temperature (I think this still would have confused you).  Here's a wiki-pedia article on it: http://en.wikipedia.org/wiki/Glass_transition

 

It's essentially the transition state between liquid and solid*.  However, as a complete solid, plastic is extremely brittle (which can confirm what you found).  If the dealer says it's what others seem to be having, I guess it's normal.  Can you link to the cable you're buying?
