TIFU by not securing my headphones

Technically this happened yesterday, but I'm still pretty mad at myself.

I've been riding my ebike pretty frequently to and from work. It's a short trip and basically the same amount of time as a car would take, so it just makes sense. My bike also has a cupholder, and I've been placing my keys in there to avoid being stabbed by them.

Yesterday, I had the brilliant idea of putting my headphones in there. I was trying to reduce clutter in my pockets and make it easier to peddle. Well, I hit a few bumps that were a little larger than usual, and with the traffic and trying to keep my head on a swivel I didn't notice my headphones bounce out of the cupholder.

I made it all the way home only to discover my massive error. Rip the $200 to replace those...
