Speaker pillow
A speaker pillow is a pillow that incorporates loudspeakers. It is generally designed to be an alternative to headphones connected to portable media players.
Research has shown that a speaker pillow may also help with the symptoms of tinnitus by masking the internal sound with an external one. See also Tinnitus masker.
