Sony WH-1000XM4 headphones, black with copper trim

I lost my Sony WH-1000XM4 wireless headphones yesterday around 3pm. They were in a black hard-case with a copper zipper, the cans themselves are matte black with a tiny dent on the right ear cup. Inside the headband there is my initials "AR" scratched in, and the case has a bit of wear on the bottom from daily use. They're a gift from my sister and I really need them back for daily calls and concentration during work; it would be heartbreaking to lose them. I last had them outside the Market Hall on Market Street in Derby city centre, near the Market Place. If you've found them, please message me here—any signal helps, thank you.
