Mystery part. Need help identifying (2 Viewers)

While cleaning out the glove compartment to a new to me 05 LX470, I found this part. It looks like a cover for a switch but I can't be sure. I checked the DVD remote and the battery cover does not match this part. I included the truck key for scale. I even did a Google Image Search but did not get a match. Any guesses?

Battery cover for headphones would be my guess.

Thank you. That maybe it. The truck didn't come with the headphones.
