Description
Household noise never arrives at a convenient moment. A door down the hall, a car pulling away outside, someone still moving around the kitchen long after you have gone to bed. This portable sound machine lays a steady, even layer of sound across the room so those interruptions stop standing out against the silence. It is small enough to live permanently on a nightstand and light enough to drop into a bag for a hotel room or a spare bed.
The library holds up to twelve soothing sounds, from plain white noise to rain, ocean and gentle fan tones, so you can pick the backdrop that suits the room and the hour. A simple volume control lets you set the level precisely, low enough to sit under conversation or loud enough to cover a busy street. The built-in timer runs the sound for a set stretch and then switches off on its own, so nothing plays all night unless you want it to.
It charges over USB, which means one cable covers it whether you are at home, at a desk or away for the weekend, and a full charge carries it through several nights of use. The controls are plain enough to work in the dark by touch alone. Use it beside a bed, at a work desk, in a nursery under adult supervision, or in a home office where the rest of the house carries on without you.
- Up to 12 soothing sounds including white noise, rain and fan tones
- Adjustable volume control for a precise, unobtrusive level
- Built-in sleep timer switches the sound off automatically
- USB rechargeable, so one cable covers home and travel
- Compact, lightweight body sized for a nightstand or a bag

Frequently Asked Questions
How does white noise help?
It raises the background sound level so sudden noises no longer stand out sharply against silence, which is what tends to wake people.
Is it loud?
The volume is adjustable across a wide range. Most people run it far lower than they expect, just enough to blur the edges of outside sound.
Can I take it travelling?
That is one of its main uses. It packs into a bag easily and makes an unfamiliar room sound like the one you sleep in at home.
Does it loop noticeably?
The tracks are chosen to run continuously without an obvious repeat point, since a noticeable loop defeats the purpose entirely.
Can it run all night?
Yes, and continuous play is how most people use it. There is also a timer if you would rather it stop once you have fallen asleep.
