I am not an HTML expert but I understand that gogl will see; IpodHay 3 productos So again H1 is lost :-( It is not completely "lost." The search bots will see: Ipod Hay 3 productos However - since the product wrapped inside the h1 tags - unless inline styling is applied or a class is assigned to the span element, whatever is inside the span (in the first example you give), will inherit the h1 properties. The H1 may also lose some focus this way - depending upon what is inside the span tags. Ideally, we should be able to edit exactly what appears inside the H1 tag on each page or as related to each product, category etc. via the Admin area. Contents of the H1 tag needs to correlate to the page title as well (for proper SEO basics). Same key phrases used in title and H1, should also appear in meta description. I don't know if there is a SEO plugin that provides this ability?
