Trouble Shooting

Q: What should I do if the pairing failed?

A:

  1. Put the earbuds back to the charging case and make sure that they are off.
  2. Take the earbuds out of the case and they are automatically on.
  3. Wait that the indicator on the left earbud flashes red and blue alternately and earbuds enter pairing mode.
  4. Choose “ST-BE30-L” in your phone to pair.

If the pairing still fails, check the following points:

  • Make sure the earbuds and your Bluetooth device are next to each other or within 3 feet and there are no obstacles between.
  • There are no signal interference nearby (check the “Connection is not stable” part for signal interference conditions).
  • Try to reboot your Bluetooth device.

Q: Earbuds are connected to phone A. What should I do if I want to pair earbuds with phone B when I am not able to disconnect earbuds from phone A?

A:

  1. Turn off the earbuds by pressing and holding the MFB buttons for 6 seconds.
  2. Press and hold the MFB button of the left earbud until the indicator on the left earbud flashes red and blue alternately and earbud enters pairing mode.
  3. Choose “ST-BE30-L” in phone B to pair and turn on the right earbud.

Q: Why isn’t the sound clear/consistent sometimes?

A: Connection is not stable.
Bluetooth signal is transmitted wirelessly and signals can be affected, which results in intermittent sound of earbuds, in the following conditions:

  • The distance between the earbuds and your Bluetooth device is at the edge of the Bluetooth pairable distance.
  • Transmitted signals encounter obstacles or human body blockage.
  • There are high-power electronic devices nearby.
  • There are other Bluetooth devices and are being turned on/off nearby.

To resume stable connection between the earbuds and your Bluetooth device, try to avoid the above conditions and do the pairing again following the steps in the pairing failed part.

Q: Is there a latency when I am watching a video from laptop or cell phone?

A:

  1. Video latency depends not only on the earbuds, but also the cell phones and the apps.
  2. Due to the Bluetooth 5.0 and high sensitivity antenna, the latency is hardly noticed on iOS devices, such as iPhone and iPad series.

For Android and Windows devices, the latency may be noticed in a few apps.

Q: Why is the power running out fast?

A: The earbuds playtime varies according to volume level and audio content. The following conditions may cause fast power consumption:

  • When the charging case is out of power, you put the earbuds back into the case and close the case, the earbuds will not turn off automatically. To avoid unwanted power consumption, turn off the earbuds manually.
  • When the earbuds are being charged in the charging case and the charging case is out of power, the earbuds will turn on automatically. To avoid unwanted power consumption, turn off the earbuds manually.
