Lost black over-ear Bluetooth headphones with a small dent, last seen near the park in Joplin.

I lost my black Bluetooth headphones while walking my dog in the park near Joplin last Saturday. I think they might have fallen out of my pocket while I was trying to wrangle my pup. They are over-ear style with a small dent on one side. If anyone has seen them, I'd really appreciate any help in getting them back.
