Frequently Asked Questions - Slumber Avantree

Is the pillow washable?

Yes, the pillow is hand washable. Before washing, remove the speakers. When reassembling, make sure the speakers are facing upward. Visit avantree.com/support/slumber/install for more instructions.

Why is the sound still audible to others despite a low volume?

Adjust the volume on both your source device and the Slumber. If sound persists, place your ear directly on the speaker and reduce the volume further.

How do I switch between MP3, Bluetooth, and AUX audio modes?

Use the MP3/AUX button to manually switch between MP3 and AUX. For Bluetooth, press the BT button once. The Slumber remembers the last used mode.

Can I add my own audio files in MP3 mode?

Yes, connect the Slumber to a PC via the USB-C cable. It will appear as a drive named 'Avantree Slumber'. Copy your MP3 files directly to this drive.

How do I set the sleep timer?

Press the timer setting button to cycle through options: 30 min, 1 h, 2 h. The corresponding LED lights up to confirm the selection.

What if Bluetooth doesn't connect?

Make sure the Slumber is in pairing mode (flashing blue/red LED). On your device, select 'Avantree Slumber'. For manual reconnection, press the BT button once.

How do I clear the Bluetooth pairing history?

Press and hold the replay/previous track and skip buttons (buttons 7 and 8) for 10 seconds until the LED flashes.

What is the difference between stereo and mono modes?

In stereo mode, the sound is split between the left and right speakers. In mono mode, both speakers play the same audio signal. Use the stereo/mono button (#10) to switch.

Does the Slumber work without a power cable?

No, the Slumber must be plugged in via the provided USB-C cable to a 5 V/500 mA-2 A power source to function. It does not have an internal battery.

Getting Started

You can use the Slumber by placing it on top of your existing pillow, or by inserting it into your pillow cover, or placing it under your pillowcase for minimal sound leakage. Make sure that both speakers are facing upwards.

The two speakers facing upward

STEP 1

The Slumber must be connected to a power source via the provided power cable in order to function. Plug the provided type C charging cable into the charging port, then connect the other end to a 5V/500mA-2A rated USB adapter (your phone charger or similar should work) or PC USB port.

STEP 2

Slide the ONOFF switch to the "ON" position to turn the Slumber on.

Choosing an Audio Mode

You can choose to stream audio in three different ways: via MP3, Bluetooth, or AUX. The Slumber will default to the last-used mode each time it's powered on.

MP3 Mode

For first time use, the Slumber will enter MP3 mode automatically, playing the built-in white noises. If not, press the MP3 / AUX button once to enter MP3 mode manually. You can change the playback mode by pressing & holding the MP3 / AUX button until the corresponding indicator turns solid white.

11 Ordered playback
1-2 Single cycle playback
Shuffle playback

The Slumber contains a built-in 4GB storage card that it uses while in MP3 mode. In addition to the 10 enclosed white noise options, you can upload your own tracks by connecting the Slumber to your PC via the included USB C cable. Transfer your chosen files to the "Avantree Slumber" disc and enjoy!

AUX Mode

Plug the AUX 3.5mm audio cable into both the Slumber and your audio output device (i.e. your phone / PC / tablet), and the Slumber will enter AUX mode automatically. If not, press MP3 / AUX once to swap from MP3 mode or twice if you're swapping from Bluetooth mode.

NOTE: The ◀◀ and ▶▶ buttons do not work in AUX mode.

Bluetooth Mode

STEP 1

Press the BT button once to enter Bluetooth mode. For first time use, the Slumber will enter PAIRING mode automatically. If not, put your Slumber into PAIRING mode by pressing & holding the BT button until the LED flashes blue and red alternately.

STEP 2

Turn on your device's Bluetooth and select "Avantree Slumber" in the Bluetooth menu.

STEP 3

Keep them close and wait for 5-10 seconds or until they connect. Once connected, the Slumber's Bluetooth connection indicator will turn solid blue.

For subsequent use, the Slumber should automatically reconnect to the last-paired device within a few seconds of being switched to Bluetooth mode. If not, you can manually activate reconnection by tapping the BT button once, or by selecting "Avantree Slumber" in your device's Bluetooth menu.

NOTE: You'll need to adjust the volume on both the Slumber & your audio device to reach the lowest volume level.

Setting a Sleep Timer

The sleep timer can be set to make the Slumber automatically turn off after a specified amount of time. You can choose among 30 mins, 1 hour, or 2 hours by pressing the Ⓤz button. The corresponding LED will light up to indicate your selection.

FAQ

Below are some of the most common questions people have during setup.

Is the pillow washable?

Yes, you can wash the pillow by hand whenever necessary. Please take out the speakers before washing. When re-assembling, make sure that the main speakers are facing upwards. You can find more specific directions on re-assembling at avantree.com/support/slumber/install.

I turned the volume down as low as possible -- why can someone else still hear?

Make sure to adjust the volume on both your device and the Slumber in order to reach the lowest volume levels. If the sound is still leaking, you can consider resting your ear directly on top of the speaker and turning the volume down even further.
