The LectroFan EVO is the sound machine most people should buy. It’s $65.95, its USB power draw keeps it the cheapest of the three to actually run, and it has more sound options than the other two combined. The Hatch Restore 3 is the one to skip unless you specifically want its sunrise alarm and dimmable light built into the same device — its $169.99 price nearly triples to roughly $420 over five years the moment you add the optional Hatch+ membership.
All three do the same basic job: mask noise so you fall asleep and stay asleep. How they get there, and what that costs you after the receipt is long gone, is where they actually differ.
I’ve slept through enough hot, humid summers to know a steady hum beats dead silence for actually falling asleep. In a small space, that hum also has to travel through thin walls without turning into another midnight annoyance.
What Five Years of Nightly Use Costs
A sticker price is one number. Running a device eight hours a night, every night, for five years is a different number — and for two of these three machines, it’s a bigger one than the box suggests.
According to Yogasleep’s own support documentation, the Dohm Classic is rated 120VAC, 60Hz, 18W. Run it eight hours a night for five years and that’s roughly 262.8 kWh, priced at the U.S. Energy Information Administration’s most recently published average residential rate of 16.48 cents per kWh — about $43.31 in electricity alone, on top of the $49.99 sticker.
Adaptive Sound Technologies doesn’t publish an exact wattage figure for the LectroFan EVO. It runs on USB power, and the USB 2.0 standard its charger uses caps output at 5V/0.5A — 2.5 watts, a ceiling rather than a measured draw. Even priced at that ceiling for eight hours a night, five years comes to about $6.02 in electricity, at the same EIA rate.
Hatch doesn’t publish a wattage spec for the Restore 3 at all, so we’re not inventing one. What Hatch does disclose, in its own membership documentation, is the subscription price: Hatch+ runs $4.99 a month or $49.99 a year. Five years of the annual plan is $249.95 — more than the device itself.
How Do the Three Sound Machines Compare on Total 5-Year Cost?
| Machine | Upfront Cost | 5-Year Electricity (8 hrs/night) | 5-Year Subscription | Total 5-Year Cost |
|---|---|---|---|---|
| Yogasleep Dohm Classic | $49.99 | ~$43.31 (18W continuous) | $0 | ~$93.30 |
| LectroFan EVO | $65.95 | ~$6.02 (≤2.5W ceiling, USB) | $0 | ~$71.97 |
| Hatch Restore 3 (no membership) | $169.99 | Not disclosed by manufacturer | $0 | $169.99+ |
| Hatch Restore 3 (with Hatch+) | $169.99 | Not disclosed by manufacturer | $249.95 ($49.99/yr × 5) | ~$419.94+ |
The LectroFan’s low-draw USB power is why it ends up cheaper to own than the Dohm over five years, even though it costs more on day one. The Dohm’s 18-watt draw running all night, every night, is a small but real ongoing cost that a sticker-price comparison misses entirely. And the Hatch’s total cost is really a decision, not a number: skip the membership and it’s a $170 alarm clock with a sound machine attached; add it and you’re closer to $420 over five years.
The Ledger: How Cost, Sound, and Features Stack Up
Price isn’t the only axis that matters, so here’s how the three score against four weighted criteria — weighted because a sound machine’s core job (masking noise well) should count for more than a nice-to-have like a headphone jack.
Running cost, 25%. Two of these three run all night, every night, for years. The sticker price is a fraction of what a device eats in power or subscription fees over time.
Sound authenticity and variety, 35%. Masking noise well enough to actually fall asleep to is the entire reason this product category exists. It gets the largest weight.
Portability, 15%. Matters if you travel or move the unit between rooms; matters less if it’s staying on one nightstand for years.
Extras beyond noise, 25%. Alarm, light, and app functions — real value for some buyers, irrelevant for others who just want it to make noise and shut up otherwise.
How Do the Three Sound Machines Score on Each Axis?
| Axis (weight) | Yogasleep Dohm Classic | LectroFan EVO | Hatch Restore 3 |
|---|---|---|---|
| Running cost (25%) | 3/5 — $43.31 over 5 years | 5/5 — $6.02 over 5 years | 2/5 — wattage undisclosed, membership can add $250 |
| Sound authenticity/variety (35%) | 4/5 — one genuine mechanical sound, zero variety | 5/5 — 22 non-looping digital sounds | 3/5 — solid free library, deeper end gated behind Hatch+ |
| Portability (15%) | 2/5 — wall outlet only, US/Canada plug | 5/5 — USB power from laptop, bank, or wall adapter | 2/5 — wall outlet, larger footprint |
| Extras beyond noise (25%) | 1/5 — none | 2/5 — timer, headphone jack | 5/5 — sunrise alarm, dimmable light, app routines |
| Weighted total | 2.70 / 5 | 4.25 / 5 | 3.10 / 5 |
The LectroFan wins on the numbers because it’s strong on the two heaviest-weighted axes — running cost and sound variety — and doesn’t have a real weakness anywhere. The Hatch wins the one axis it was built to win, extras, by a wide margin; that’s the whole case for buying it. Where the Dohm struggles on this ledger isn’t that it’s bad — it’s that “one sound, no features” scores low on a four-axis system almost by definition, which is worth knowing if variety and features aren’t what you’re shopping for.
Three Machines, Three Different Philosophies
Yogasleep Dohm Classic: real fan noise, nothing else
The Dohm Classic is a genuinely mechanical device. A small internal fan spins inside a vented housing, and turning the outer ring adjusts the pitch by changing how much air escapes. There’s no digital sound file and no loop point. It runs at 120VAC, 60Hz, 18W, according to Yogasleep’s own support documentation, and it lists for $49.99 directly on Yogasleep’s site.
Owner feedback consistently describes the Dohm as sounding less “digital” than app-based alternatives — the pitch changes are continuous, not stepped. The recurring complaint is the flip side of the simplicity: two speeds and one sound type means no ocean waves, no brown noise, and no way to soften the sound below its lowest setting. If a nursery is the destination, keep it several feet from the crib rather than a few inches, and follow Yogasleep’s placement and volume guidance rather than assuming quieter is automatically safer.
Skip this if: you want any sound besides fan noise, or you’d rather not pay for an 18-watt device that has no off switch beyond the wall outlet.
LectroFan EVO: Most Sound Options, Cheapest to Run
The LectroFan EVO generates its sounds digitally and non-repeatingly: 10 white-noise variations, 10 fan-sound variations, and 2 ocean-surf options, for 22 total, confirmed on the manufacturer’s own product listing. It’s USB-powered rather than tied to a wall outlet. It includes a sleep timer in 60-minute increments up to 8 hours and a headphone jack, a feature neither competitor offers. It lists for $65.95 directly on the manufacturer’s site.
Long-term owners consistently cite more sound variety and easier travel power — it runs off a laptop, a power bank, or a wall adapter — as the reason they picked it over the Dohm. The recurring criticism is that several of the 22 sounds are close enough to each other that most owners settle on two or three favorites and ignore the rest.
Skip this if: you want a nightlight or an alarm clock built into the same device. It has neither, and isn’t trying to.
Hatch Restore 3: the alarm clock that also makes noise
The Restore 3 is a different category of product wearing a sound machine’s clothes. Beyond white noise, it includes a dimmable nightlight, a sunrise-simulating wake-up light, and app-guided sleep and wake routines. It lists for $169.99 directly on Hatch’s own site. Hatch’s own membership documentation confirms the core device — sound machine, alarm, and nightlight — works without any subscription; the optional Hatch+ membership is $4.99 a month or $49.99 a year and unlocks a larger sound and light library.
Owners consistently point to the sunrise alarm and the combined light-and-sound “wind down” routine as the reason they’d pay triple the Dohm’s price. The recurring frustration, echoed across retailer reviews, is that the deepest parts of the sound and light library sit behind that optional membership — which some buyers feel undercuts an already premium price.
Skip this if: $170 up front and a possible $50-a-year membership doesn’t feel worth it just for a sunrise light and app routines you could get from a $15 plug-in timer and a cheaper sound machine.

| Hatch Restore 3 | $169.99 | Free library + larger Hatch+ library | Wall outlet, wattage undisclosed | Sunrise alarm, dimmable light, app routines | Core features no; expanded library yes (optional, $4.99/mo or $49.99/yr) |
Checking Sound Machine Marketing Against the Spec Sheet
Three claims worth verifying instead of repeating.
Claim: the LectroFan EVO has “22 non-looping sounds.” Reality: confirmed on the manufacturer’s own product listing — 10 white-noise variations, 10 fan-sound variations, and 2 ocean-surf options add up to 22. This one checks out exactly as advertised.
Claim: the Hatch Restore 3’s core features — sound machine, alarm, nightlight — work without any subscription. Reality: confirmed in Hatch’s own membership documentation, which lists customizable routines, sunrise alarms, 40 sleep sounds, 20 alarm sounds, and 20 lights as included free. The subscription genuinely expands rather than unlocks basic function. Also true.
Claim: Yogasleep positions the Dohm as making “real” fan noise, implicitly against synthetic alternatives like the LectroFan. Reality: also true, mechanically — Yogasleep’s own specs describe an actual motor spinning an actual fan, not a digital recording. Whether that’s better for you is a preference question this comparison can’t answer for you; whether it’s an actual mechanical fan rather than marketing language for a speaker, it is.
Which One I’d Buy
If you already know you prefer real fan noise to a synthesized track, the math above stops mattering as much. Buy the Dohm Classic and don’t worry about the roughly $21 you’re leaving on the table over five years compared to the LectroFan.
But if sound type is a genuine toss-up for you, the LectroFan EVO is the one I’d buy. It’s cheapest to actually run, has the most sound options, and is small and USB-powered enough to travel with. The Hatch only earns its price if the sunrise alarm and dimmable light are things you’d buy separately anyway — priced that way, bundling them into one device starts to look reasonable. Priced as “just” a sound machine, it doesn’t.
