The $20 pocket white noise machine — 3.4 ounces, USB-C, and the travel answer the rest of the lineup can't give.
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 roughly a full night per USB-C charge. Three sounds — bright white noise, deep white noise, and gentle surf — with an unbroken volume dial. 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.

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?
Roughly 24 hours per USB-C charge per the listing metadata — comfortably a full night with margin. Charge it while you're out for the day and it's ready by bedtime.
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.
