Lost gray Plantronics wireless headset

Lost a compact wireless headset yesterday around 3pm near the Peoria Public Library on Main Street in downtown Peoria. It's a gray and black Plantronics headset, roughly the size of a small paperback, with a red LED glow on the right earcup. The charging case has a tiny dent on the top edge and a white sticker with the initials 'A.N.' inside the lid. It was a gift from my sister last summer and really means a lot to me—I use it for work calls and my commute, so I hope it turns up. If anyone found it, please message me; I would be grateful to get it back.
