Ros, 24, who was a product of the Basque outfit's youth system, leaves having spent 12 years with the club.
Angel and Granero, meanwhile, spent last season on loan from Roma and Queens Park Rangers respectively, but have now returned to their parent clubs.
Granero is widely expected to leave QPR this summer, but thus far Sociedad have been unable to agree a transfer figure with the London outfit.
