Lost white wireless Bluetooth headphones with a small keychain at a café near Birmingham city center.

I lost my white wireless headphones while I was at the cafe near the Birmingham city center yesterday afternoon. I remember putting them on the table while I was enjoying my coffee, and when I got up to leave, I forgot to grab them. They are Bluetooth, and I had attached a small keychain to them. If anyone finds them, I would really appreciate getting them back.
