Wow thanks for the reply color coded and everything :o The thing about the myth was that there were some people (I heard it somewhere never really followed up on it) say that when you have detachable cords/corded on one side it would affect the longevity of the sound balance (one side's sound deteriorates more than the other) and that with the wear and tear of the detachable cord it reduces life as well. I know the product is decently new so I wouldn't expect you to know for this specific model but in general would that be something to worry about? Seeing as how you didn't get my question I don't think it seems like a real problem in general.
Edit: LOL I actually DID read your review on it earlier haha very helpful :)
Ah I see. I haven't had much experience with detachable/1-sided headphones to be honest, so I cannot guarantee that there won't be a problem. I think if you take care of the cables and headphones properly, you should be fine. So far I haven't heard any news about that around Head-Fi.
In the event where it does happen, Shure does offer a 2-year limited warranty that covers all defects in material and workmanship so that might be covered in the warranty.
