Oh, that's cool, I'd like to congratulate you on your anniversary in advance. I think that the AirPods Pro 2 headphones are a pretty good gift, knowing how much girls love Apple technology, they're just crazy about it. This model is the latest model that exists, there are also AirPods Max, but they are big and more suitable for computer games than for walking around the city or training, so you clearly didn't make a mistake in the gift and you should do it.
