Black Sony WH-1000XM4 headphones near Library of Birmingham

I found a pair of black Sony WH-1000XM4 wireless headphones this afternoon around 4pm outside the Library of Birmingham, near Centenary Square. They're in good condition, with the matte finish showing only light scuffs on the headband. The right earcup has a small sticker with faded initials 'JH' and a bright blue USB-C cable poking out of the navy zip case. The case itself is slim, with a subtle chevron pattern along the edge. They clearly belong to someone who was in town for meetings or events. If you’ve lost them, I’d like to help get them back to you—just drop a note with distinguishing details.
