Accepted Answer

Without a network connection, Calm audio (Sleep Stories and Meditation) cannot be played. However, if the audio has already been played, it will be cached and can be played offline within 15 days.

Question 15

What should I do if Sleep A30 Special doesn't fit securely?

Accepted Answer

1. Make sure you are wearing the ear tips and ear wings correctly.
2. Choose the ear tips and ear wings that fit your ears the best. We recommend that you start with size M ear tips and ear wings.
3. Insert the earbud into your ear and find a suitable position for the best fit. If the earbuds are too deep in your ears, it may affect the Bluetooth connection. If you experience connection issues, we recommend that you replace the ear tips and wings with larger ones.
4. Try other sizes of ear tips to ensure the one you're using fits well and create a tight seal. If one earbud feels stable and the other does not, try a combination of ear tips such as medium in the left and large in the right.

Question 16

What should I do if I feel strong pressure or discomfort in my ears after wearing Sleep A30 Special for a long time?

Accepted Answer

1. Try using the foam ear tips for a better fit.
2. Look at the L / R logo on the back of the earbuds to ensure that the correct earbud is in the correct ear. Turn the earbuds while wearing them and find the most comfortable position.
3. When using them in bed, try a different pillow. Pillows that are too hard may exert more pressure on your ears if you sleep on your side, which may cause discomfort and affect the connection to your phone.
4. Do not use water pillows or pillows with metal or magnetic components.

Question 17

What can I do about strong discomfort in my ear while sleeping on my side?

Accepted Answer

Make sure you're wearing the earbuds correctly. We recommend trying different ear wings and ear tips, and/or switching to a softer pillow.

Question 18

Why do the earbuds squeak when they rub against my pillow when I sleep on my side?

Accepted Answer

The squeaking is from friction between the earbuds and pillow material, which could be an issue especially when the pillow is made with a smooth fabric. To reduce this noise, try adjusting the earbuds, using a pillowcase, or switching to a softer pillow.

Question 19

How do I turn on my Sleep A30 Special?

Accepted Answer

1. The earbuds turn on automatically when the charging case is opened.
2. For first-time use, remove the insulating sheet under the earbuds, place the earbuds back into the charging case, and then open and close the case to turn them on.

Question 20

What can I do if the double-tap function on my Sleep A30 Special doesn't work or isn't responding properly?

Accepted Answer

1. Tap more firmly, as the earbuds use a G-sensor that requires a stronger tap for detection.
2. Tap using your fingertips as the earbuds respond better to them.

Question 21

What should I do if my Sleep A30 Special is prone to accidental double-taps or mistouches?

Accepted Answer

1. The earbuds’ G-sensor may mistakenly detect double-taps or mistouches. To reduce such instances, please avoid dropping the earbuds on hard surfaces, rolling them around, or using them during vigorous exercise.
2. When placing a single earbud in the charging case, double or triple taps may be triggered, causing mode switches or volume changes. This is not a malfunction, but rather the earbuds detecting a tap when placed in the case. This is how the sensor operates and is completely normal.

Question 22

How do I reset Sleep A30 Special?

Accepted Answer

Open the charging case, place the earbuds inside, and press and hold the Reset button on the back of the charging case for 10 seconds. The indicator light inside the charging case will start flashing quickly, indicating it is in pairing mode, and blink slowly once pairing is successful.

Question 23

How does Sleep A30 Special connect to the soundcore app?

Accepted Answer

1. On your device's Bluetooth settings, tap “Sleep A30 Special” to pair.
2. Open the soundcore app > Add Device > Sleep A30 Special to connect to the soundcore app.

Question 24

Why is the volume level inconsistent after switching modes?

Accepted Answer

1. Local Mode is designed to help you sleep at night and plays noise-masking frequencies (or white noise) at a preset volume. The system remembers your previous Bluetooth audio playback volume, ensuring that mode changes don't disrupt your sleep.
2. Bluetooth Mode is intended for daily entertainment like music or podcasts. In this mode, volume can be controlled directly from your phone, giving you more flexibility.

Because these two modes have different functions, the volume of what you're listening to will also vary.
You can adjust the volume separately for each mode, and the system will remember your preferences in Local Mode. If you find that the difference in volume when switching modes significantly impacts your experience, please feel free to share your thoughts with us in as much detail as possible. We’ll pass along your feedback to our product team to make improvements.

Question 25

How do I switch between Bluetooth and Local mode?

Accepted Answer

1. Double-tap the left earbud (turns the earbuds on by default).
2. Switch through the soundcore app.
3. When the earbuds detects that the user is asleep, they will automatically switch to Local mode and play the built-in white noise by default.

Question 26

How do I adjust the volume in Local mode?

Accepted Answer

You can adjust the volume manually through the soundcore app, or by tapping the earbuds.
Binaural Mode: Triple-tap the left earbud to decrease the volume, and triple-tap the right earbud to increase the volume. You can also control the volume directly from the app.

Note: In Local mode, the volume cannot be adjusted using the volume buttons on your phone.

Question 27

How do I use the Sleep Onset Detected feature?

Accepted Answer

You can access Auto-Switch Once Asleep settings within the app:
1. Play Local Audio, ANC Off: After detecting you've fallen asleep, the device (if playing audio) will switch to Local mode and turn off active noise cancellation.
2. Pause Audio: After detecting you've fallen asleep, the device will switch to Local mode, stop audio playback, and maintain pre-sleep active noise cancellation settings.
3. Keep Audio: After detecting you've fallen asleep, the device will stop playing audio and maintain pre-sleep audio and active noise cancellation settings.
Note: If no audio is playing before you fall asleep, audio will not play after you fall asleep.

Question 28

How long can Sleep A30 Special earbuds be used on a single charge?

Accepted Answer

With active noise cancellation (ANC) enabled, it can provide up to 9 hours of playback time. If sleep is detected, Bluetooth playback stops automatically for an undisturbed night. The times presented below were measured in soundcore labs with the volume set at 50%.
Other Usage Scenarios:
- Bluetooth Mode with ANC On: 6.5 hours
- Local Mode with ANC On: 8.5 hours
- Bluetooth Mode with ANC Off: 10 hours
- Local Mode with ANC Off: 14 hours

Note: It is recommended to charge the earbuds before sleeping to ensure enough battery for a full sleep cycle.

Question 29

What can I do if my Sleep A30 Special earbuds won't charge?

Accepted Answer

1. Make sure the earbuds are properly placed in the charging case. Check that the ear wings are correctly in place and that nothing is blocking the charging pins.
2. Clean the charging pins on the earbuds and in the charging case.
3. If the charging case battery is below 5%, it may stop charging the earbuds. Try recharging the case first, then place the earbuds back inside.

Question 30

Why is my Sleep A30 Special's battery draining quickly?

Accepted Answer

1. In Bluetooth mode with ANC on, battery life is up to 6.5 hours at 50% volume. In Local mode with ANC on, the earbuds can last about 9.5 hours. Please ensure the earbuds are fully charged before use.
2. Turning off Bluetooth on your phone while the earbuds are in Local mode keeps them in search mode temporarily, which increases power consumption.
3. Over time, regular use and charging can cause natural battery wear, which may reduce overall battery life. This is normal.

Note: When sleep is detected, the earbuds switch to Local mode to conserve battery. If the alarm clock is enabled, it uses approximately 5% of the battery, leaving 95% of battery charge for playback.

Question 31

How to Fix Sleep A30 Special Earbuds Charging Issues? 1) The earbuds won't charge in the charging case. 2) The earbuds stay connected to my device even after being placed in the charging case and the lid is closed. 3) The earbuds won’t turn on after being taken out of the case.

Accepted Answer

1. Ensure that the ear tips and ear wings are properly attached and not blocking the charging pins. Insert both earbuds securely into the charging case. The indicators should light up to indicate the earbuds are connected.
2. Use a dry cloth or a cotton swab with a small amount of alcohol to gently clean the charging pins inside the case and on the earbuds. This ensures a better connection.
3. Use a different charging cable and wall adapter to fully charge the case. Make sure the case is charging properly.

If your earbuds have not been used for a long time, charge them for at least 2 hours first and see if this fixes the issue.

Question 33

How many times can I charge my earbuds with Sleep A30 Special's charging case?

Accepted Answer

Question 34

Why does one earbud drain battery faster than the other?

Accepted Answer

1. One earbud is designated as the primary earbud, which usually consumes more power. A difference of up to 20% in battery usage between the two earbuds is normal.
2. Battery drain can also be affected by factors such as volume level, type of audio played, interference in the environment, and features open in the app. These factors are for reference only, and your actual experience may vary.

Question 35

Do the earbuds support wireless charging?

Accepted Answer

Question 36

What should I do if there is no indicator light after opening the charging case lid?

Accepted Answer

2.If the charging case firmware version is 1.31, please update it to version 1.57 or later to resolve the issue.

Question 37

What do I do if Sleep A30 Special disconnects, or the sound is intermittent?

Accepted Answer

Please note that this does not necessarily mean that there is a problem with the earbuds, and may be related to your connected device and surrounding environment. Bluetooth signals can be affected by obstacles like walls, pillars, household appliances, Wi-Fi, and more. To ensure a stable connection, we recommend avoiding such obstacles.

To resolve this issue, please try the following steps:
1. Adjust earbud position, or try using larger ear tips and ear wings. Inserting the earbuds too deeply may interfere with the antenna and affect the stability of the Bluetooth connection.
2. Shorten the distance between your earbuds and phone for better connectivity.
3. Fully charge and reset the earbuds by following these steps:
Open the charging case and place the earbuds inside. Press and hold the Reset button on the back of the case for 10 seconds to reset the earbuds.

Question 42

What if there is little or no sound coming from one of the earbuds?

Accepted Answer

1. Please pause audio playback or other operations on your phone while downloading.
2. Please check that you have a stable network connection.

Question 55

White noise looping sounds unnatural.

Accepted Answer

We recommend trying different white noise options.

Question 56

Why is the Sleep A30 Special Sleep Test not accurate?

Accepted Answer

The earbuds detect sleep or wakefulness based on your movement, then generate local data in the app. Because everyone moves differently while asleep, some degree of error in detection is normal.

Question 57

Why is there no Sleep Report data?

Accepted Answer

Principle of sleep detection: The earbuds determine whether you're asleep based on your amplitude of movement within a specific time window. If there is minimal movement over 30 minutes, the earbuds will judge that you’ve fallen asleep and generate local sleep data. However, if you frequently toss and turn or move your head during sleep, the earbuds may misjudge that you’re still awake, resulting in no sleep data being recorded.

To rectify the issue, we recommend:
1. Reconnecting the earbuds. The latest sleep data syncs to the app only when the earbuds are connected.
2. Not opening the app every time you go to bed.
3. Connecting to the app once a week to make sure your data stays up to date.

Question 58

Why doesn’t the Sleep Reminder do anything when I turn it on?

Accepted Answer

The Sleep Reminder feature only works within the app and requires the app to be running in the foreground for the reminder to appear. Currently, reminders are not supported directly through the earbuds to avoid disrupting your listening experience.

Question 59

How do I download white noise to my Sleep A30 Special?

Accepted Answer

White noise must be downloaded through the soundcore app while your earbuds are connected in Bluetooth mode. Downloads are supported in both Local and Bluetooth mode, but third-party audio cannot be imported. Only 1 white noise track can be saved in your earbuds at a time.

How to download:
1. Open the soundcore app and go to “Audio Library”
2. Tap the “White Noise” tab and select the audio you want to download
3. Tap the Up-Arrow icon at the bottom of the play bar
4. Tap “Transfer” in the pop-up menu to start the download 
5. Once download is complete, the white noise will automatically be saved to your earbuds and be available for playback in Local mode

Question 60

Why can Sleep A30 Special only store one white noise sound locally?

Accepted Answer

Compared with Sleep A20, Sleep A30 Special features improved sound quality for white noise playback. This means each file requires more storage space, which limits the number of white noise tracks that can be stored locally. If you'd like to store a different white noise sound, please delete the current one and then add your preferred option.

Question 61

How do I set the playback duration for Local mode?

Accepted Answer

Switch to Local mode. Then, select “Playback Duration”. The default duration is set to two hours, but you can choose your preferred playback time.

Question 62

How do I turn the tapping feature off?

Accepted Answer

Select “Tap Control” to enter settings, then toggle the feature on/off in the desired mode.

Question 63

Can I add music from my phone to the Audio Library in Local mode?

Accepted Answer

Adding your own music to the Audio Library is not supported. You can only select from the existing tracks available in the Audio Library. To play your own music, please use Bluetooth mode.

Question 64

Can AI brainwave audio be added to the built-in audio of the earbuds/transmitted to the earbuds?

Accepted Answer

AI Brainwave audio requires dual-channel Bluetooth support and can only be played in Bluetooth mode. This feature is not supported in Local mode.
Note: If you play AI brainwave audio in Local mode, the sound will come from the connected device.
