Midnight blue wireless earbuds in charging case

I found a pair of wireless earbuds this morning around 8:15am outside the Seaport area along Duval Street in Key West, Florida Keys. The charging case is midnight blue with a small dent on the bottom corner and a red sticker with the initials MK on the back. The buds are matte black with a thin white ring around the edge and a couple of light scratches from being jostled in a pocket. They look newer, and I really hope to help the owner get them back — if this sounds like yours, tell me where you last used them and what the sticker says, and we can arrange a meetup.
