Nitetronic Smart Anti-Snore Pillow can recognize and filter sounds of your partner’s snoring but please note: If there is only one Nitetronic Anti-Snore smart pillow, it is recommended to be used by people with more severe snoring. Please keep a distance of more than 4 inches between the pillow and your partner's pillow. According to the users’ feedback, the snoring intervention sensitivity can be lowered to the suitable level on the APP, then the intervention effect of the pillow will be better.
