The Chinese invented a pillow speaker for 2,100 rubles - it allows you to listen to music, podcasts and even an alarm clock without disturbing the person next to you. The new product from Baseus transmits sound through vibrations directly to the pillow, so that those around you hardly hear anything. Inside there are more than 100 sleep sounds, including rain, the sound of the sea and the crackling fire. Charging lasts all night. Worries can be calm.
