For side sleepers

Your Ear Is AlreadyAgainst the Speaker

Lullabar is 11mm thin and sits under your pillow. Lie on your side and the ear resting on the pillow is the ear that hears it. Nothing goes in, on, or around your ears.

You Have Already Tried the Others

Every fix for sleeping with audio has the same flaw: it puts something between your ear and the pillow. Then you turn over.

  • Earbuds

    Lying on your side presses the bud deeper into your ear canal. The ache builds inside the first hour, and it is still there in the morning.

  • Sleep headbands

    Elastic holds them against a head that turns all night. They shift, they bunch behind your ear, and they get warm.

  • A phone on the mattress

    It plays into the room instead of into your ear, it runs warm under a pillow, and whatever arrives at 3am arrives out loud.

Eleven Millimetres, Under the Pillow

Slide Lullabar under your pillow. Sound travels through the fill to the ear resting on it, which is why lying on your side makes it clearer rather than quieter.

Where It Falls Short

Worth knowing before you order, because 30 nights only means something if you know what you are testing.

  • On a very thin pillow you may notice the edge for the first few nights. Most people stop; some never do.
  • Very thick memory foam muffles it. Standard down, polyester and down-alternative fill carry sound best.
  • It softens snoring rather than removing it. A loud snorer still comes through.
  • It is a speaker, not a medical device. It will not treat insomnia and does not claim to.

What people notice first

Works perfect, plenty of sound through the pillow. would purchase again.

Common Questions

Yes, and more clearly than back sleepers do. Lying on your side presses your ear into the pillow, which shortens the path between the speaker and your ear. The position that makes every other sleep audio device uncomfortable is the position that makes this one work best.
At 11mm and 47.5 grams, most people stop noticing it after a night or two. It sits under your pillow, not against your face. On a very thin pillow you may notice the edge at first, which is one reason the trial runs 30 nights rather than a week.
Standard fill carries sound best: down, polyester, and down alternative. Thinner pillows transmit most clearly. Very thick memory foam muffles it. Slide Lullabar under the pillow, or inside the pillowcase on its underside.
Yes, in every position. On your side you hear it through the ear resting on the pillow. On your back you hear it through the back of your head, but it needs more volume, and at that volume the person beside you can hear it too. On your front it still reaches you, a little quieter. You do not have to hold a position to keep the sound.
Yes. Set the sleep timer (30 / 60 / 120 min) and playback stops on its own. One charge runs 10+ hours at normal volume, so the timer is there to end the sound once you are asleep, not to save battery.
