The Marpac Dohm UNO: Can a Sound Machine Be Too Simple? (Our Review)

A Look at Radical Simplicity (and Who It's For)

Using the Dohm UNO is as easy as turning on a lamp, maybe even easier. You plug it in, and you flip the single switch. The real fan inside starts creating that natural, soothing whoosh of air. Then, you simply twist the outer shell of the machine. This physically opens or closes the vents, which changes the tone of the sound from a deep, bassy hum to a lighter, airier rush. You just find the tone you like, and you're done.

• The ultimate in simple operation.
• Natural, soothing, fan-based sound.
• Compact and great for any room.

The absolute beauty of the Dohm UNO is that there's nothing to mess up. There are no apps that need updating, no Bluetooth that needs to be paired, and no bright blue digital lights that you have to cover up with electrical tape. It's a simple, mechanical device that is built to do one thing reliably for years and years. It creates the perfect, distraction-free sound environment for a baby's room or a light sleeper's bedroom.

Now, this machine is the very definition of simplicity with its single fan speed. It's perfect for someone who wants to just turn it on and not have to think about it at all. It's just good to know that if you're someone who really likes having a distinct "high" and "low" volume option, the Dohm Classic model has two speeds.

Even with just one speed, you have a great range of control over the character of the sound just by twisting the cap. It's all about finding that perfect pitch that masks outside noises and lulls you or your baby to sleep. Because it's a real fan creating the sound, it's a rich, full noise that never repeats, which many people find is the real secret to a truly restful night.

The Dohm UNO is for the true minimalist who believes that simpler is almost always better. It delivers that legendary, natural fan sound in the easiest-to-use package you can possibly imagine. If you want a no-fuss, set-it-and-forget-it solution for better sleep, this is an absolute classic.
