Not exactly
dropped phones, but I once had my Koss Plugs ( i know, I know...) fall out of my pocket when I was getting into my stepfathers car. I closed the door, leaving them hanging on the ground outside, we drove off to work, and commented there was a weird rattling noise under the car.
I got to where I work, got out of the car and thought oops my phones are hanging out of my pocket, looked down and theres just wires, no earphones at all left, just bare wire and a little blob of solder on each end.
Sent them back and got a new pair under warranty

lol
