"The JH 13 Pro's superthin cable didn't make any noise when it rubbed against my clothing, and it wasn't prone to tangling and it is user replaceable. That's not the case with any standard, universal fit in-ear headphone I know of; when those cables break, you either toss the 'phone, or pay for a repair."
It at least used to be the case with the Ultimate Ear's super.fi or triple.fi lineup. Though I read recently I believe that they are doing away with the replaceable cables on their models.
"I think you can expect to get at least 10 years of use out of the JH 13 Pros."
Oh, I wouldn't go so far as to say that with customs.
