The Totenreich map in Black Ops 7 Zombies introduces a new musical easter egg that players can solve by locating three Mister Peeks Headphones. These headphones are distributed across the map, and interacting with all three triggers the unlocking of the song "No One There", composed by Kevin Sherwood and Vicky Psarakis.

Below are the precise locations for each headphone, which can be found in any order.

All Mister Peeks Headphone Locations in Black Ops 7 Zombies

Dry Dock

In the Dry Dock area, locate the massive central boat. Drop to the ground and move to the right side of the boat. Proceed to the middle of the boat’s base, where you’ll find a box atop the crates containing the headphones.

Core Foundry

Head to the room opposite the Double Tap Root Beer machine in Core Foundry. Enter from the side of the machine, then turn right. Near the wall, you’ll encounter old machinery. Crouch down to spot the headphones among the machinery on the ground.

Loven's Antiquities

Upon spawning in Loven's Antiquities, enter the building through the main door. Pass the desk and examine the cupboard filled with plates. The headphones are located on the bottom shelf of the cupboard.

Once all three headphones are collected and interacted with, the easter egg will activate, playing the track "No One There".
