Found these way out in the woods, one was 5" down beside giant tree. not shotgun shells. Any ideas? Small flaps on one side..?

It could be pieces from a rotten away headphones

Here are closer pics, one has a flat back, and one an iron back with grooves in it.

I'd guess a variation of the snap pieces shown in the upper left here: https://www.aliexpress.com/item-img/...00017.1.a6amYq

I'm also thinking they could be some sort of fastening hardware for jeans or jean jacket?
