Sony WH-1000XM4 headphones, black, lost Boston

I lost my Sony WH-1000XM4 wireless headphones yesterday around 3pm. They're black, over-ear cans in decent shape, with a tiny dent on the right ear cup and a green fabric headband that’s worn from daily use. I think I left them near the Boston Public Library steps on Copley Square after rushing to catch the T. There’s also a small blue sticker with the initials 'BP' under the left ear cup. They were a gift from my sister and mean a lot to me, so I’d really appreciate getting them back. If anyone found them, please text me here and we can arrange a quick pickup in Back Bay.
