Yogasleep Rohm Portable White Noise Machine (USB-C)
Best for: Travel, hotel rooms, strollers, white-noise users on the move
The pocket white noise machine — 3.4 ounces, USB-C, and the travel answer the rest of the lineup can't give.
Worth itIt fits in a pocket: a low-cost way to take your sleep environment with you.The Rohm is the first true travel machine in our lineup: 3.4 oz, palm-sized, with a lanyard for a stroller or hotel headboard, and a USB-rechargeable battery that the brand describes as long-lasting. Three sounds, per the brand: white noise, bright white noise and deep blue noise, with adjustable volume. It's digital and loop-based, so fan purists should stay with the Dohm at home; this is the machine you pack. Current units charge over USB-C; older stock at third-party sellers may still be micro-USB.

How our prices work
We show the price at our recommended retailer as at our last check of that offer (2026-11-12) and, when Amazon reports one, its list price for comparison. Amazon prices come from Amazon's own product data service and are refreshed twice a day; each one shows the date and time Amazon gave it, and one older than 24 hours is replaced by “Check price”. Other retailers' prices are checked by hand and show the date of that check. Retail prices move constantly, so the price on the retailer's own page at checkout is the one that applies.

Frequently asked questions
Rohm vs Dohm — which Yogasleep do I want?
Dohm for the nightstand (real fan, mains power, richer sound), Rohm for the suitcase (digital, rechargeable, 3.4 oz). Many owners end up with both; they solve different problems.
How long does the battery last?
Yogasleep does not publish a battery-life figure. It describes the Rohm as having long battery life for naps, flights and overnight stays.
Is my unit USB-C or micro-USB?
Yogasleep's current production (SKU 4005200) is USB-C. Older stock still circulating at third-party sellers is micro-USB — if buying outside the brand site, check the listing's port before ordering.
Can it run while plugged in?
Yes — it plays while charging, so a dead battery at bedtime isn't a blocker if you have the cable with you.
