You cannot soundproof a place you do not own. Thin walls, a road outside, a neighbour whose day starts at five: none of it is fixable, and all of it is survivable with the right sound in the room. White noise works by raising the background level so individual noises stop standing out, which is why a steady hum beats earplugs for most people.
There are 24 sounds here across white noise, fans and nature. The important detail is that they are non-looping, so you never get the short repeating sample that eventually becomes the thing keeping you awake.
A soft yellow night light is built in and can be turned off entirely, which makes it genuinely useful beside a cot without lighting the whole room. For night feeds that combination of steady sound and low light does a lot of work.
An auto-off timer means it does not run all night unless you want it to, and the volume adjusts fine enough to sit just above the street noise rather than replacing it with something louder. At 11 x 11 x 7 cm and well under half a kilo it fits in hand luggage, which matters because hotels are noisier than home.
This suits new parents, shift workers, students in noisy buildings and anyone who has mentioned not sleeping well. It is one of those gifts that sounds mundane and then changes somebody's week, which is a fair return on a present.
Pair it with a decent eye mask and you have given someone a complete sleep setup. For a baby gift, it is worth noting it works just as well for the parents, who are usually the ones awake.
