Black Sony WH-1000XM4 headphones near Seattle Central Library

I found a pair of black Sony WH-1000XM4 wireless headphones this afternoon around 1:45pm outside the Central Library's main entrance on 4th Ave in downtown Seattle, in the Seattle-Tacoma area. They're matte black, in decent condition with a few scuffs along the headband. The left earcup has a tiny dent, and there's a blue sticker with the initials 'JZ' on the underside of the headband. They came with a gray faux-leather carry case. They powered on when I pressed the power button, so they seem usable. If these are yours, tell me the sticker initials or describe the dent to prove ownership, and we can arrange a pickup near the library.
