This easter egg in BO6 Zombies Reckoning map requires you to find and collect three hidden headphones around the new map. You can interact with any of the headphones in any order; the goal is just to find three of them to kick off the secret Reckoning song. Here is a complete guide to hunt all three headphones in Call of Duty Season 5.
All Headphone Locations in Call of Duty Zombie Reckoning
Once you collect all the headphones, the easter egg will play a song called Remember Us by Kevin Sherwood and Elena Siegman. You must interact with every one of the headphones to collect them. You can use the interact key to perform the interaction.
#1| Headphone Location| T1 Mutant Research Test Area
Make your way to the T1 Mutant Research Area. On your immediate left, you will find two cryo chambers. Next to the chamber with a Disciple inside, you will find a zombie corpse holding a pair of headphones in its left hand.
#2| Headphone Location| Dark Entity Containment Room
Head to the second level, Android Assembly, located in tower two. Here, grab the elevator, head through the doorway to enter the T2 Dark Entity Containment Room. Once you are in the location, take the stairs to the lower floor. On your left, you will see three large monitors; the first monitor will have a dead zombie lying on its machines. Interact with the headphone around the zombie’s neck to cross the second collectible.
#3| Headphone Location| Director’s Office

Head inside the Director’s office, follow the route to the Pack-A-Punch machine, which will lead you to the office. Once you are inside the Director’s Office, don’t take the portal behind the desk. The room has multiple bookshelves, but our prize item is hidden inside the bookshelf located next to the monitor. Here, check the bookshelf behind the office desk located in the corner of the room. You will find the third and last headphone in one of the cabinets at the bottom of the bookshelf.
Now the song Remember Us will play in the game.
That completes a part of the easter egg for the main story in BO6 Zombies Reckoning. Like in the previous maps and easter egg, this one, too, has a pretty involved set of steps for you to complete to get the ending.
