I need help with finding something that fell in the dirt?

i was walking my dog while listening to my iPod when suddenly a stray dog attacked my dog of course my dog was able to pull me hard enough to make the leash slip through my fingers.The leash got tied around the headphones ( or the other way around) and then my dog ran with the leash dragged behind it.After i recovered my dog and my iPod i still can't find my headphones.they are black headphones and the dirt is brown.I already tried searching with a flashlight.What should i do?
