Choose Dohm Classic when you specifically want the sound produced by a real internal fan and simple physical adjustment. Choose LectroFan Classic when you want several digital fan and noise options plus a sleep timer. Keep your existing sound source if it already provides the sound and controls you prefer.

Yogasleep Dohm Classic
LectroFan Classic
A dedicated sound machine is mainly a way to choose and repeat a background sound without relying on another device. The best purchase depends on which sound you enjoy and how you want to control it. Specifications alone cannot establish a universal winner for sleep or comfort.
Compare how the sound is made
| Question | Dohm Classic | LectroFan Classic |
|---|---|---|
| Sound generation | Real internal fan | Digital sound generation |
| Choices | Two speeds and housing adjustment | Ten fan sounds and ten noise options |
| Sleep timer | Not on the cited Classic | Included |
| Power arrangement | 120 V AC plug-in version | USB cable and AC adapter |
When Dohm is the right purchase
Yogasleep’s Classic uses a fan motor and rotating housing to alter the sound. It is a fit for someone who wants that physical sound source with few controls. Do not confuse it with another Dohm model that adds lighting, connectivity or timers.
The current cited Classic is designed for US/Canadian 120-volt use. It is not a rechargeable travel machine. Check the exact version when comparing imports, and allow the operating clearance described in its instructions.
When LectroFan earns its place
LectroFan Classic supplies multiple digitally generated fan and noise options, volume adjustment and a sleep timer. That can be more useful when you are unsure which pitch you prefer or want the machine to stop after a chosen period.
USB power describes the supply connection, not a built-in battery. Include a suitable power source in your intended placement and check what the seller includes. Do not transfer specifications from LectroFan EVO or other related versions to the Classic.
Match the sound to the real problem
Listen to demonstrations as a starting point, while recognizing that your phone or laptop speaker changes what you hear. We have not tested either machine’s sound, volume range or masking in a bedroom. A recording cannot establish how the unit will sound beside your own bed.
These products add sound rather than physically soundproofing the room. If the problem is a loose fitting, vibrating furniture or a door gap, address that source as appropriate instead of expecting a sound machine to remove it.
Who should buy or skip?
Buy Dohm for the real-fan method and simple control. Choose LectroFan for the range of sounds and timer. Keep a working fan, speaker or other suitable source if it already gives you the background you want. Compare return terms because sound preference is personal, and avoid paying for a second machine without a clear feature you will use.
