Sorry kids, but it's story time...
When I got my UM1s is found the long complys to have the best sound of the univeral tips. Noticing that they would get a bit dirty after about a week of wear, I would clean them with warm water and a mild detergent. This was what I had done long before with triple flanged tips on my Etys. The problem is that they foam on the Complys don't always respond well to washing.
After washing a pair of Comply tips, I had the foam separate from the stalk of the tip while removing it from my ear. I had experienced Disclocated Tip Syndrome (yes, I'm going to trademark that) earlier when I was an early adopter of the Etymotic er-6i. However, in this case it was in pretty deep, and caused me to be very disturbed. To make matters more uncomfortable, I was in the middle of my commute, stuck on a train heading into downtown Chicago. I give many thanks to my Leatherman Micra, and the less than perfect tweasers that are supplied on them, for being able to recover from the situation. While the tools that I had at my disposal were not the best, I was able to dislodge offending foam.
It was in the seconds after removing it, that I made the decision to upgrade to custom tips.
My overall recomendation would be not to wash Comply tips. Wear them until they don't seal as well as they should, and then replace them. Stock up when you purchase to make the shipping a bit better.
good luck, and avoid "foam ear"
