It seems that DICE has added a set of headphone Easter Eggs within Battlefield 1.
Reddit user Nehefer found the first set of headphones within the game’s Fao Fortress map, and this revelation lead to other Redditors finding heaps more on maps like Sinai, Amiens, Monte Grappa and Empire’s Edge.
Finding a set of headphones causes a sound to play and the headphones themselves to disappear. They seem to spawn randomly; only one player can get each.
We’ll let you know when players figure out what they do.
