How PillowConduction Works
No earbuds. No bedside speaker. Just sound that travels through your pillow, right where you need it.

The basics
Sound Through Your Pillow, Not Through the Room
A regular speaker pushes sound into the air. Everyone in the room hears it. That is great for music at dinner — not so great at 11 PM when your partner is already asleep.
Lullabar works differently. It sits under your pillow and transmits vibrations into the pillow material itself. Your pillow essentially becomes the speaker — conducting sound toward you while the surrounding air absorbs very little of it.
The result is a personal audio zone that stays close to you. At normal listening volumes, the sound dissipates within inches.
Three steps
From Pillow to Sleep Sounds in 30 Seconds
Slide It Under
Place Lullabar between your pillow and pillowcase, near where your ear rests. The 6mm profile is completely invisible — you should not feel it at all.
Connect & Play
Pair via Bluetooth 5.3 in seconds. Stream from any app — Spotify, podcasts, Calm, or use 100+ built-in sleep sounds.
Drift Off
Set a sleep timer (30, 60 or 90 min) and let the audio fade as you fall asleep. Most people only need sound during sleep onset.

What Sounds Work Best
Pillow conduction excels at certain types of audio. Here is what to expect so you can get the most out of your Lullabar.
Sounds great through a pillow
Rain & nature sounds
Low-frequency ambient audio travels beautifully through pillow material.
Brown & pink noise
Deep, steady masking sounds are where pillow conduction really shines.
Ocean waves & fan sounds
Rhythmic, continuous sounds feel enveloping and immersive.
Guided meditations & podcasts
Speech comes through clearly at comfortable volumes.
Ambient & lo-fi music
Gentle, bass-forward music sounds warm and cosy.
Good to know
Not hi-fi headphones
Lullabar is designed for bedtime, not critical listening. Think cosy and immersive, not studio-grade.
Very high-pitched audio may soften
Pillow material naturally absorbs some treble. Most users do not notice.
Volume sweet spot matters
Too loud and your partner may notice. Too quiet and you may not hear it. A little calibration the first night goes a long way.
Pillow thickness varies results
Thinner, firmer pillows conduct sound most clearly. Very thick or fluffy pillows may soften audio slightly.

Placement & Setup Tips
A little experimentation goes a long way. Here is what our community of 50,000+ sleepers has found works best.
Position near your ear
Place Lullabar underneath your pillow, roughly where your ear rests. Side sleepers: shift it slightly toward the side you sleep on.
Pillow in pillowcase
Sliding Lullabar between your pillow and pillowcase keeps it in place all night. No slipping, no adjusting.
Start at low volume
Begin quiet and raise to a comfortable level. In a quiet room, you need less volume than you think. This also keeps partner disturbance to a minimum.
Use a sleep timer
Most people only need sound while falling asleep. Set the 30, 60, or 90 minute timer and let it fade out naturally. Saves battery too.
Give it two nights
Like a new pillow, it takes a night or two to find your ideal placement and volume. Most users find their sweet spot by night two.
Charge during the day
With 12+ hours of battery, charging once or twice a week during the day is enough. We recommend not charging while under your pillow.
Pillow compatibility
Works With Any Pillow
Lullabar is designed to work with the pillow you already have. Here is how different materials perform.
Memory foam
ExcellentDense material conducts vibration really well. Clear, rich audio.
Latex
ExcellentSimilar to memory foam — firm, consistent contact gives great sound transfer.
Polyester fill
Very goodThe most common pillow type. Lullabar works well in standard to medium thickness.
Down & feather
GoodWorks well, though very fluffy down pillows may soften the sound a little. Place Lullabar closer to the top surface.
Buckwheat
Very goodFirm and dense — conducts sound nicely. The pillow conforms around the device.
Hybrid / gel
Very goodMost hybrid pillows have a firm-enough core for great sound transfer.
The partner question
“Will My Partner Hear It?”
This is the question we get asked most — and we want to give you an honest answer.
At normal listening volumes (the level that is comfortable for bedtime), your partner should not be disturbed. Sound travels through the pillow toward you and dissipates quickly in the surrounding air. Our users consistently tell us their partners do not notice.
That said, Lullabar is not a pair of sealed headphones. If you turn the volume up high, some sound will be audible to someone lying right next to you. The good news: most masking sounds (rain, brown noise, fans) work beautifully at low-to-moderate levels — you do not need it loud for it to be effective.
Tip: do a quick calibration together. Play your preferred sounds and ask your partner if they can hear anything. Most couples find a volume that works for both on the first night.
