Generally speaking they don't use expensive engineering plastic in these kind of products anymore. UV light does more damage to plastic than anything else.
I the case of travel headphones, oil from you skin and hair likely did the most damage. I had to replace the ear cushions on my Sennhaisers but the QC2 was used less and it stood up ok.
