Black wireless earbuds charging case with blue USB-C cable

I found a black wireless earbuds charging case this afternoon around 3:15pm in the parking lot behind the Walmart on Lee Trevino Drive in Southwest El Paso, near Cielo Vista Mall. The case is black with a tiny dent on the lid and a blue USB-C cable is still plugged into the port. Inside there's a blue sticker with the initials 'A.R.' on the bottom edge and a light scratch along the edge where it rubbed against a pocket. It looks fairly new, no water damage or noticeable wear. If you're missing these, message me with the initials on the sticker and the approximate model you had; I’d be glad to reunite them with you.
