Question 13

What should I do if Sleep A30 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.
5. Please refer to this video on how to use Sleep A30: https://youtu.be/gtXbSUZSY-Y?list=PLYHuc9nw_t9px6fbU8qgtIgQ6aPJn0_w_

Question 14

What should I do if I feel strong pressure or discomfort in my ears after wearing Sleep A30 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 15

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 16

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 17

How do I turn on my Sleep A30?

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 18

What can I do if the double-tap function on my Sleep A30 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 19

What should I do if my Sleep A30 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 20

How do I reset Sleep A30?

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.

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

Question 24

- Left earbud: Double-tap > Switch mode, Triple-tap > Decrease volume
- Right earbud: Double-tap > ANC on / off, Triple-tap > Increase volume
2. You can customize or disable tap functions in the soundcore app.

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 28

Why is my Sleep A30'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 29

Earbuds: 90 min
Charging case: 120 min

Question 30

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

Question 31

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 34

What do I do if Sleep A30 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:

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 53

Why is the Sleep A30 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 54

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 55

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 56

How do I download white noise to my Sleep A30?

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 57

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

Accepted Answer

Compared with Sleep A20, Sleep A30 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 58

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.

Note: If you play AI brainwave audio in Local mode, the sound will come from the connected device.

Question 62

Why is the battery level shown in the app different from the actual level?

2. To check the current battery level of the charging case, place the earbuds back into the case and open the app. The value displayed will reflect the most up-to-date status.

Question 63

Why does audio from the Audio Library play through the phone's speakers?
