Pillow with two speakers built-in and a heart headphone splitter.
Sounds from speakers can be heard only by a person lying on the pillow.
Speakers can play independently from two different devices.
There is a heart-shaped headphone splitter in the set that allows connecting two speakers to the music from one device.
You can control the easily sound level from the music source, e.g. a smartphone.
Speakers in a pillow are not perceptible, and you will sleep soundly.
It does not require an additional power supply. It has a 3,5 mm plug (mini-jack - standard for all music players).
