Lost black Bose QuietComfort headphones possibly left at a cafe on the Brighton beachfront.

I was out for a walk in Brighton on the beachfront when I realized my Bose QuietComfort headphones were missing. I must have left them at the cafe I stopped at for a coffee right before heading down to the beach. They're black with a little wear and tear, but still work perfectly. I'd really love to get them back as they were a gift from my husband.
