Lurking in the auditory shadows of radio static lie well-documented yet mysterious, disembodied voices undetectable to the human ear. Known as Electronic Voice Phenomenon (EVP), researchers believe these sounds may be spirits communicating from another realm.

Sinister Speaker, a type of "spirit box," swiftly scans radio frequencies with a fixed channel producing constant white noise. Researchers suggest spirits can manipulate audio within these frequencies for messages and two-way communication. Features a built-in mic, headphone line-in, and Bluetooth connectivity.

Light and highly portable, Sinister Speaker functions as a stylish Bluetooth speaker or traditional radio when not scanning for ghostly sounds.



Sinister Speaker offers four different millisecond sweep speeds for a thorough scan between frequencies: 87.5-108 MHz on FM, 522-1710 KHz on AM, and 3200-22000 KHz on shortwave radio.
Capture recordings via TF/SD up to 4GB and unlimited USB 2.0 storage.
No batteries – recharge with a standard Type C cable for up to 4 hours of continuous use.
Backlit menu ensures ease of use in dark spaces.

Setup: Place or carry device in target area. Connect headphones via line-in or Bluetooth. Insert TF/MicroSD or USB. Adjust reverb and pitch for optimal audio quality. Let the Sinister Speaker record baseline ambient noise.
