Slumber B (USB-C) – How to Fix Low Volume

If your Slumber B sounds too quiet, first check the speaker position and the volume on both Slumber B and your connected device.

Quick Check

For the best volume, place Slumber B inside your pillowcase, on top of the pillow, close to your ear. Then turn up the volume on both Slumber B and your phone, tablet, or computer.

Step 1 – Check the Speaker Position

Place Slumber B inside your pillowcase, on top of your pillow. Position the speaker close to where your ear rests.

Watch the Video Demonstration

Why this matters: Slumber B is designed for close, gentle bedtime listening. If it is too far from your ear or underneath a thick pillow, the sound may seem much quieter.

Step 2 – Turn Up Both Volume Levels

Slumber B's final volume also depends on the volume coming from your connected device.

Increase the volume using the Slumber B volume control.
Increase the volume on your phone, tablet, or computer.

Important: If either volume level is set low, Slumber B may still sound quiet even when the other volume is turned up.

Step 3 – Play Different Audio and Check Again

Try another song, video, audiobook, white noise track, or app. Some recordings and apps are naturally quieter than others.

Test the volume while lying normally on your pillow.

Still too quiet? Move Slumber B slightly closer to your ear inside the pillowcase and test again.

Something Doesn't Look Right?

Only One App or Audio Track Is Quiet?

Try another app or audio track. If other audio sounds normal, the original app or recording may have a lower audio level.

Still Too Quiet?

Try connecting Slumber B to another compatible phone, tablet, or computer and test the volume again.

If the volume is normal with another device, the original device's audio output or volume setting may be limiting the sound.
