I just got a pair after christmas, S/N 2524XXX, so that's pretty close, on the wrong side. They do cut out when used in a jeans pocket, and sometimes even the inner (chest) pocket of a winter jacket if i turn my head to the right.
It's funny though, because if i put my phone (iPhone 6) on the kitchen counter, I can walk a fair distance away from it before I get problems, so it seems it's mostly to do with attenuation from the body.
I'm a little bummed if it turns out I was this close to get a pair with a fix. Especially as I'm pretty happy otherwise...
