Slumber 2 – Fix Low Volume

Follow these steps if Slumber 2 sounds too quiet.

First, Check Where the Volume Is Low

Only Bluetooth audio is quiet: Check the volume and sound settings on your phone or other connected device.

Bluetooth audio and built-in sleep sounds are both quiet: Start with Steps 1 and 2 below.

Step 1 – Move the Speaker Closer to Your Ear

Place Slumber 2 inside the pillowcase.
Keep the speaker on top of the pillow, not underneath it.
Move the speaker close to where your ear normally rests.
Play audio while lying in your normal sleeping position, then test the volume.

Move the speaker a little closer to your ear if it is still too quiet.

Step 2 – Turn Up Both Volume Controls

Slumber 2 and your phone or other Bluetooth device have separate volume controls. Turn up both.

Slumber 2: Turn the volume scroll wheel on the remote up.
Phone or other device: Turn up its media volume.

If only Bluetooth audio is quiet, also check your device for a volume limit, media-volume setting, hearing protection, or “Reduce Loud Sounds” setting.

Step 3 – Voices Are Hard to Hear?

If the volume is high enough but voices are unclear, switch to Voice Clear mode.

Slumber 2 has two remote versions. Hold the correct Voice Clear button on your remote for 5 seconds to switch between Balanced and Voice Clear.

Still Too Quiet? Test the Speaker Outside the Pillow

Take Slumber 2 out of the pillowcase.
Play audio and hold the speaker near your ear.
If it sounds louder, put it back inside the pillowcase and move it closer to where your ear rests.

Still Too Quiet? Try Another Phone or Device

Disconnect Slumber 2 from your current phone or device.
Connect it to another phone, tablet, or computer.
Turn up the volume on both devices.
Play audio and test again.

If it is louder with the other device, check the sound settings on the original device.

Still Too Quiet? Reset Slumber 2

Turn on Slumber 2 and switch it to Bluetooth mode.
Press and hold the Previous Track and Next Track buttons together for 10 seconds.
Wait for the Bluetooth light to change.

Solid PINK = Reset is starting.

Flashing RED and BLUE = Reset complete and ready to pair.

Reconnect Slumber 2 to your phone or other device, turn up both volume controls, and test again.

Sound Only on One Side?

Check the speaker connection and the left/right audio balance on your phone or tablet.
