In *Big Walk*, the microphone puzzle asks players to identify the microphone position that produces balanced sound in both ears for a teammate sitting in a nearby chair. It matters because it relies on clear communication and stereo audio, making headphones or earbuds particularly helpful.

The puzzle is found south of the radio station, west of the yellow tower, beside a red platform with six microphone stands. One player should speak into one microphone at a time while the seated player signals whether the sound is in the left ear, right ear or both; the speaker then adjusts position and presses the stand’s button once balanced audio is heard, repeating the process as needed.
