Yogasleep lists the Dohm Classic at $49.99 on yogasleep.com under SKU 3500350, in white, gray, black, tan, and pink. The device measures 5.6 by 5.6 by 3.5 inches, weighs 31.5 ounces, and plugs into a 120V AC outlet through a 7-foot cord. Inside the shell is a fan motor; there is no speaker, no audio file, and no radio of any kind. Everything you hear is air moving through vents whose openings you change by twisting the outer cap and rotating an inner collar.
Four Yogasleep pages carry the record: the listing, the FAQ, the model chart across the five Dohm models, and the warranty registration page. Between them they answer what the machine does mechanically, what it costs and what it lacks, and they disagree once, about how long the warranty runs. Every sleep claim in the listing is Yogasleep's own and is left as their statement.
Our verdict
Buy the Dohm Classic for a steady mechanical fan sound with two speeds and hand-adjusted tone, if you can live without a timer or a battery. At $49.99 it is the plainest device in Yogasleep's lineup with tone adjustment.
- A good fit for
- Bedrooms and nurseries with a free 120V outlet, people who dislike looped audio recordings, and a buyer who wants a device with no screen, no pairing, and no firmware.
- We would skip it if
- You travel outside the US and Canada, want the sound to switch off on a timer, need a portable or battery unit, or want a sound other than moving air.
Reasons to consider it
- Sound is generated by a real fan motor in a tuned housing, so it never loops or restarts
- Volume and tone are set mechanically: twist the cap for volume, rotate the collar for tone, plus a two-speed switch
- Yogasleep states a 30-night trial, free US shipping over $40, and HSA/FSA eligibility on the listing
The compromises
- 120V AC only, with a 7-foot cord; Yogasleep says it is not compatible with international voltage standards
- No sleep timer, no night light, no app, and no battery; the $69.99 Dohm Nova adds light and timer if you need them
- The listing says 1-year limited coverage while Yogasleep's registration page says 2 years upon registration, so the effective term depends on whether you register
What we have not verified: Yogasleep does not publish the motor's wattage or current draw, the decibel level on the low setting, or the noise spectrum. The 57.4 dB figure at six feet on high is a manufacturer statement, and every sleep benefit in the listing is Yogasleep's own claim, not a finding.
The things in this guide
A closer look at the products, who they may suit, and what to check before buying.
Dohm Classic White Noise Machine (SKU 3500350)
For $49.99 the Dohm Classic gives you two fan speeds, a volume cap, and a tone collar in a 31.5 ounce housing that needs nothing but a 120V outlet. Yogasleep's comparison table shows the cheaper $39.99 Dohm Uno drops to a single speed and no tone control, so the Classic is the entry point for a buyer who wants to tune the sound at all.
Before you buy: No timer and no battery. If you want the sound to stop on its own or need to run it off the grid, Yogasleep's Dohm Nova ($69.99) adds a 45 minute, 90 minute, or 8 hour timer, and none of the Dohm line is battery powered according to the table.

Yogasleep describes the Dohm Classic as a real fan motor spinning inside a tuned acoustic housing, with no audio files, no loops, and no speakers. The sound is therefore made live by moving air: no track length, no restart point, and none of the brief gap a looped recording leaves when it wraps around. People who notice that seam in a phone app or a smart speaker are the audience this design addresses. The mechanism is what the company says it is, a small fan in a shaped shell with vents, and a fan can only sound like a fan, so anyone wanting rain, surf or pink noise is in the wrong product line.
Two parts shape the airflow, and Yogasleep's FAQ says which does what: rotating the outer cap changes the volume, rotating the inner collar shifts the tone from a deeper hum to a brighter rush of air. Both adjustments happen by hand on the unit and stay where you leave them, with no memory to lose and no app to resync. A nursery or shared bedroom tuned once and left alone benefits from that. Two continuous mechanical controls give finer adjustment than a stepped volume button, and neither has markings, so a setting someone else moves has to be found again by ear.
Two speeds and a stated 57.4 dB ceiling
The Classic has a two-position speed switch, and Yogasleep states that on high it measures up to 57.4 decibels at six feet, which the company compares to a quiet conversation. That is an upper bound for a machine meant to sit near a bed or crib and cover household and street sound at a moderate level, not to fill a large room. Light sleepers in apartments with hallway or traffic noise are the buyers this ceiling matters most to. No figure is given for the low setting, so the character of the sound cannot be judged from the listing.
Yogasleep frames the benefit as a steady sound layer that keeps sudden noises from standing out, and white noise that helps the brain stay asleep. Those are the manufacturer's claims about sleep. What the mechanism delivers on the company's description is a continuous broadband sound that varies slightly as air moves and never repeats, which is the tangible difference from a phone app, and the loudness figure is the practical one. Buying on the mechanism and the tone control means treating any sleep improvement as something to judge during the 30-night trial, because nothing on the listing quantifies how well the unit masks a specific noise.
120V, a 7-foot cord, and a 31.5 ounce footprint
Yogasleep lists the Dohm Classic at 5.6 by 5.6 by 3.5 inches and 31.5 ounces, and says the box contains the machine plus a 7-foot 120V AC power cable. Just under two pounds is heavy for a device this size, which reflects a real motor and a rigid shell and means the unit stays put on a nightstand when the cord is tugged. Parents placing it on a dresser near a crib, or anyone with a cat that pushes things off shelves, will read the mass as a feature. The footprint is nightstand-scale and the cord reaches most outlets behind a bed. Yogasleep publishes no wattage or amperage, so running cost and behavior on a low-power timer plug are unknown.
The listing says the unit is for use in the United States and Canada only, and the FAQ adds that it runs on 120V AC and is not compatible with international voltage standards. In practice that rules it out as a travel companion for anyone flying to 230V regions unless they carry a step-down transformer, and a plug adapter alone will not do. Frequent international travelers and expats are the group this constraint actually affects. The Classic is a fixed bedroom appliance rather than a portable sound source, and that chart lists every model in the line, from the Uno to the Connect, as Plug-in (AC), so the constraint belongs to the family and not just this unit.
Warranty terms, the 30-night trial, and where $49.99 sits in the lineup
The listing's trust bar reads 1-Year Warranty and 30-Night Trial, and its returns text accepts a return within 30 days of shipment for a refund of the product price and tax, with free ground shipping in the contiguous US over $40. Yogasleep's separate registration page says the company provides a 2-year limited warranty when you register the sound machine. On a device with a motor and a switch and little else to fail, the term mostly covers those two parts, and a second year is worth having on a unit that runs all night every night. The two pages disagree, and the longer term is the one that requires an action: register it on day one.
Yogasleep's comparison table positions the Classic at $49.99 between the $39.99 Dohm Uno, which has one speed and no tone control, and the $69.99 Dohm Nova and Dohm Connect, which add a night light with a 45 minute, 90 minute, or 8 hour timer, or app control respectively; the standard Dohm at $49.99 is listed as the same two-speed design with a modern update. Buyers who want tone adjustment and no extras land on the Classic by elimination: $10 over the Uno buys the second speed and the collar, and $20 more buys features this model leaves out on purpose. The table also lists every model as Plug-in (AC), so no amount of extra money buys a battery.
When to skip the Dohm Classic
Skip the Dohm Classic if you need the sound to stop by itself; there is no timer, and Yogasleep's table shows the $69.99 Dohm Nova as the model in the family that adds one. Skip it if you travel abroad, because the 120V AC power supply is not compatible with international voltage according to Yogasleep, and the unit has no battery mode. Skip it if you want any sound other than a fan, since the entire Dohm line is mechanical and only the company's other product families play recorded audio. Skip it if you want a night light or app control, both of which cost $20 more in the Nova or Connect.
Buy it if the appeal is precisely the absence of those features: a two-speed fan in a 31.5 ounce shell, a cap for volume, a collar for tone, a 7-foot cord, and a stated 57.4 dB at six feet on high. At $49.99 with a 30-night window, the trial text promises a refund of the product price and tax. Register the unit to move the warranty from the listing's one year to the two years the registration page describes. What stays unknown is the motor's power draw, the low-speed loudness, and whether the sound improves anyone's sleep, which is Yogasleep's assertion.
