Hushh+

The rain sound on this actually got my toddler down in ten minutes, which never happens. Battery lasted four nights before I had to plug it in, and I love that I can stream my own playlist through it too.

Took this on a weekend trip and the battery lasted all three nights without a charge, which I honestly wasn't expecting. The white noise track is the one I keep coming back to, and streaming my own playlist over Bluetooth was a nice bonus.

I've had it running the rainfall track every single night for two weeks straight and the battery barely dipped below half. The Bluetooth pairing was instant, too, which surprised me since my old machine took forever. Perfect for a fussy sleeper who's always traveling.
