I’ve struggled with insomnia since I was very young. Like many chronic overthinkers, I tend to fall asleep best when my mind is occupied by something else, such as podcasts, YouTube compilations, or my personal favorite: rain sounds. But earbuds can be uncomfortable, and playing audio out loud isn’t exactly considerate when I’m staying at my partner's place.

That’s why I was intrigued by the new Peace Duo Under-Pillow Speaker from Jabees. Launched last month, this ultra-thin speaker utilizes bone conduction technology—which sends vibrations through your skull directly to your inner ear—to transmit sound through your pillow and into your ear privately. Just place it beneath your pillow and listen as you drift off.

In my testing, I found the Peace Duo was so thin that I almost forgot it was there. I mainly used the built-in sleep sounds, which come preloaded on a micro SD card with four hours of soothing soundscapes, including gentle waves, light rain, rain with thunder, and soft wind. For more personal content, the Peace Duo also offers Bluetooth connectivity, so you can connect your phone and stream your favorite audio.

Battery life is another standout. A single charge lasts up to ten nights of one-hour listening sessions, so you won’t have to remember yet another device that requires nightly charging. The foldable design also makes it easy to put away in the included magnetic fabric travel case.

There is one important caveat: it doesn’t work well with thick memory foam pillows. Unfortunately, that’s what I normally use, so I switched to a regular cotton pillow and the sound came through clearly. (The company claims that thinner memory foam pillows should work fine.)
