Sony WH-1000XM4 wireless headphones with case

I lost my Sony WH-1000XM4 wireless headphones yesterday around 3pm near the Grand Central shopping concourse by Birmingham New Street, West Midlands. They're black, over-ear, in good condition with a small dent on the left ear cup and a faint scratch near the Sony logo. The case is a matte black hard shell with a blue interior and a sticker with the initials 'AK' on the lid. They were a gift from my sister, so losing them has been stressful—I'd really appreciate getting them back.
