Query: If only they didn't die so quickly...

I've been using this model for years, but recently it seems like the build quality has gone way down. 4 pairs have died on me in the last two years. The most recent one died after less than 2 months of use. In all cases, one of the ears stops producing sound. Too bad because otherwise I really liked these earphones.
