Matte black Sony WH-1000XM4 headphones

Yesterday around 3pm I realized my matte black Sony WH-1000XM4 headphones were missing. They were in their black leather case with a red interior, and the left earcup has a small dent near the Sony logo. I last had them outside the Cumberland Valley Library parking lot by Main Street, then walked toward Riverside Market on North Main before realizing they weren't in my backpack. They mean a lot to me—they've got sentimental value and I use them daily for study and calls, plus they're a gift from my sister, so I really hope to get them back. The case has a white sticker with the initials 'AB' on it, and the ear cushions are wearing a bit, but otherwise they're in good shape.
