IEM shorts - How to know where it's coming from

I have Brainwavz M3 in-ear monitors and, before sending them out to be fixed, I want to know if the problem probably resides in the earbuds themselves or in the audio jack. See Extended explanation... Thank you.
Hi. I have Brainwavz M3 in-ear monitors that for reasons I won't go into I love and want to keep (a replacement pair I ordered sounded awful). It's two years now and there's a short. First it was in the left ear, now it's both, but intermittent. When I move or sometimes even touch the cable, which I wear around the back of my ear to reduce microphonics, all the sound comes back...but may go out again.
I want to send the IEMs out to get fixed, but would like to make sure where the problem is coming from. The fixer told me if it was the buds themselves, they will be too delicate to fix; if it's the audio jack, he can probably replace that. Three's a slight communication thing with him and I can't make out what his best guess is. If he can't fix, I'd rather not wait weeks to find that out...
The earphones still work fantastic about 70% of the time but I want the old reliability back for my commute. I baby these but always thought the jack was pretty sturdy, and that most care should be taken around the buds. I can see nothing wrong on the exterior of the whole product. It seems strange to me that both buds would develop a short around the same time unless there were some common source/reason -- like the jack. Sure, first I thought it was just a wire problem in the left bud. I would not even attempt soldering or anything technical. Can anyone tell me where the problem is likely to lie? Thanks.
