Over the last two years, I have spent about $700 dollars (3x the cost of my iPhone) on 4 different pairs of in-ear headphones that have broken. Wires, connections, shocking my ears have all been part of the experience.
Now for the last week, I have been thinking I am going deaf because I need to turn everything to 11 just to hear it. Then I plugged in a different pair, and almost had my ear drums burst form the loudness.
