Slumber 2 – Fix Low Volume – Avantree Support

Slumber 2 Low Volume

Start With the Speaker Position and Volume

These are the most common reasons the Slumber 2 sounds too quiet. Follow the steps below in order.

First, check where the volume is low

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

Bluetooth and built-in sleep sounds are both quiet: Start with the Slumber 2 volume and speaker position.

Before You Start

Check the Position

Keep the speaker close to where your ear rests.

Turn Up Both

Raise the Slumber 2 volume and your phone volume.

Test Again

Play audio while lying in your normal sleeping position.

Step 1 – Check the Speaker Position

The speaker position can make a big difference in volume.

Place Slumber 2 inside your pillowcase.
Keep the speaker on top of the pillow, not underneath it.
Move the speaker close to where your ear rests.
Play some audio and test the volume.

Still too quiet? Move the speaker a little closer to your ear and test again.

Watch: How to Position Slumber 2

The video shows how to position the speaker close to your ear for better volume.

Step 2 – Turn Up Both Volume Controls

Slumber 2 and your phone or device have separate volume controls.

Slumber 2

Turn the volume scroll wheel on the remote up.

Phone or Device

Turn up the media volume.

Important: Both volume controls may need to be turned up.

Only Bluetooth is still quiet? Check your phone for Volume Limit, Reduce Loud Sounds, Hearing Protection, or Media Volume. You can also try another song, video, or app.

Step 3 – Voices Hard to Hear? Try Voice Clear

If the volume is okay but voices are hard to understand, try Voice Clear.

Slumber 2 has two remote versions. Use the guide below to find the correct button.

Hold the indicated button for 5 seconds to switch between Balanced and Voice Clear.

All sounds are too quiet? Continue to Step 4.

Step 4 – Test the Speaker Outside the Pillow

Take Slumber 2 out of the pillowcase.
Play some audio.
Hold the speaker near your ear.

Louder now? The speaker is working normally. Put it back inside the pillowcase and move it closer to your ear.

Still very quiet? Continue to Step 5.

Step 5 – Try Another Phone or Device

This checks whether the low volume is coming from your phone or Slumber 2.

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

Louder now? The original phone or device is likely causing the low volume. Check its sound settings.

Still very quiet? Continue to Step 6.

Step 6 – Reset Slumber 2

A reset can clear temporary Bluetooth problems.

Turn on Slumber 2.
Switch to Bluetooth (BT) mode.
Hold the Previous and Next Track buttons together for 10 seconds.
Watch the BT light.

Solid Pink — Reset is starting

Flashing Red and Blue — Reset complete and ready to pair

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