In that price range you'll find decent stuff from brands like SteelSeries, HyperX, or Corsair at Spanish stores like MediaMarkt or Amazon.es, though you might have to settle for entry-level models. The important thing is to specifically search with the "ships from Spain" filter to avoid the wait, and read the reviews about the microphone because that's where a lot of cheap models fall short. If you're willing to spend a bit more, going for 60-70€ opens up way more options with better audio and mic quality, but with your budget it's not impossible to find something that works fine for gaming.
