Baby monitors with headphone jack

Headphone jack

— the ability to connect headphones to the parent unit and output audio notifications through them. This, on the one hand, will allow you to hear the signals better and not miss them even in noisy environments, and on the other hand, will minimize excessive sounds from the parent unit, which is useful when you need to maintain silence. The most commonly used headphone jack is a standard mini-jack 3.5 mm.
