Custom announcement for each brand using blocks

So my actual goal is to have my announcement bar have different contents depending on the product vendor of the product. My block have a text input area wherein I would like to input the brand I want the announcement is for. For some reason, it’s not working so I think I might be doing something wrong. Hope someone can point me in the right direction.
Here’s the code:

{%- for block in section.blocks -%}
  {%- case block.type -%}
    {%- when 'promo_announcement' -%}
    {%- if product.vendor == {{ block.settings.brand }} -%}
      
        

          

{{ block.settings.desktop_announcement }}

          

{{ block.settings.desktop_announcement }}

        

      

      
        

          

{{ block.settings.mobile_announcement }}

          

{{ block.settings.mobile_announcement }}

        

      

    {%- endif -%}
  {%- endcase -%}
{%- endfor -%}
