I wanted some earphones today while I go mow the lawn, but the Shure's were still not fixed due to my laziness. So I got on shure.com to start the process (aka procrastinate the lawn mowing) and found a link to a troubleshooting forum thread sounded like my issue. They suggested wax is 90% of the repairs that come in, but also moisture can cause a phone to stop. They say wait overnight to dry it out. I tried them a week after they broke last summer but they were still dead. But I figure I should try again after a long dry winter. Sure enough, they are working again now. Just in time for little league baseball games.

I will try to store them in a dry place like near an AC vent in the future.
