I'm going to try this..I did take it apart a while ago and used a qtip with rubbing alcohol and seemed to remove some dirt..the person at the place where I bought them from told me that it's not a good idea to kkeep taking them off of the cable..maybe cause it loosens the connection..I have noticed that the right side where I'm having the problem.isn't as tight as the left side. It's not a big difference but it's there..and these things ain't the easiest to take apart that's for sure.
One side of mine is tighter as well. I actually just cleaned mine tonight (first time in about four months. A toothpick pointed through a doubled folded paper towel, dipped in alcohol. It took me about three repeated light cleanings this way before no black dirt was coming out of the female connector portion.
And no ... to also echo your comment above ... they are *not* easy to get apart (one of mine is much harder to pull apart than the other).
That said, I'm going to clean mine whenever necessary and if the connection ever loosens to the point that they no longer perform even when cleaned? Then I'll certainly warranty service (I've had nothing but stellar experiences with Shure's return/warranty process, BTW...with both microphones and headphones but especially headphones. In fact, I got an early pair of Shure E4C's silicon tips stuck in my ear and wrote a sort of funny letter about how long it took me to get it out, which it really did and instead of sending me new nozzles for the E4C's, which I asked for originally, they actually sent me a free pair of brand new Shure SE530s *and* new nozzles for my E4C's; true story). I've also warranty serviced that same pair of free SE530's for a split cable later on and had no issues.
But give the cleaning method a try; you want to so shape the paper towel (with the toothpick) that it fits all the way in to the housing connector.
Best of luck.
