Query: Low reliability

I've had these for 4 months and now I have a short in the right earbud. It's outrageous that a pair of $170 headphones would short in 4 months, despite my careful care. I mostly just leave them at work, they hardly even travel. I thought the sound was good, though I'm no audiophile... and the ear attachments are plentiful with enough foam buds to fit any ear if you have the sense to get them in right. But to short completely like this is just absurd. Now I'll have to pay shipping to get it fixed... so angry! I'll never buy shure again, or any expensive ear buds for that matter.
