Graphic: Shep McAllister

If excessive noise or utter silence makes it difficult for you to doze off, this white noise machine might be the key to a better night’s sleep.

Marpac’s Dohm-DS boasts a 4.4-star average on over 6,000 reviews, so it’s safe to say it’s a well-vetted product. We’ve seen it get down to $40 a on a few occasions, and $31 once, but $41 is a solid deal, and $9 less than usual.
