Snooz

Snooz solved a small problem precisely. Looped white-noise recordings have a repeat you can learn to hear; the Snooz Pro generates its sound with a real fan inside an acoustic enclosure — genuinely random, fully non-looping, with tone you adjust by physically opening and closing the shell. Fan sound without the airflow, the cold, or the electric bill.

It's the kind of single-purpose object this directory respects: one job, mechanical honesty, no app required (though one exists for scheduling). For light sleepers, urban bedrooms, and anyone sharing walls, masking noise is among the cheapest meaningful sleep upgrades — and this is the considered version of it.
