Lost black Bose Bluetooth headphones with a scratch on the left ear cup and charging case near Chautauqua Park.

I lost my black Bose Bluetooth headphones while hiking around Chautauqua Park in Boulder on October 15th. I remember adjusting my hair and putting them in my bag, but somehow they've gone missing. They have a little scratch on the left ear cup, and the charging case is included. If found, please let me know!
