Mike Murphy, Quartz:

FIFA has pretty strict rules around what it calls “ambush marketing,” where a brand pays players to wear or use its products before or during World Cup games, even though that company has not paid to be an official World Cup sponsor. It’s why any player you see wearing Beats headphones before a game, for example, has the company’s logo taped over.

Apple is not a World Cup sponsor, so no Apple logos on any player gear. But check out all the photos. Even without a logo, there’s no mistaking those AirPods. Apple’s design work here is so distinctive, no logo is needed.
