What should I do if the earbuds keep disconnecting or sound is constantly being interrupted?
Please note that this doesn't necessarily mean there is an issue with the earbuds, but may have something to do with the connected device and environment. Bluetooth signals may be influenced by obstructions, such as walls, pillars, home appliances, Wi-Fi, and more. To ensure a stable connection, we recommend avoiding such obstructions:

We kindly ask you to try the following troubleshooting as they have often proven to help:
1. Try reducing the distance between your right earbud and your audio device, like having your audio device in your right pocket or keeping it on your right side. Your right earbud is the master (main) earbud. It connects to your audio device and to the left earbud.
2. Reset the earbuds as per the following steps:
- Delete the pairing history from your Bluetooth device.
- Place the earbuds in the charging case and leave the case open. Press and hold the reset button on the charging case for 10 seconds until the LED indicators on the charging case start to scroll and then stay on for 5 seconds. At this time, your earbuds have been successfully reset.
3. Reset your Bluetooth connection by turning off the Bluetooth from your device (phone/tablet/etc.) for at least 10 seconds and then turning it back on. Please note, turning Bluetooth off and back on quickly will not reset the connection.
4. Try closing any other apps you are not using on your device.
5. Test the earbuds by listening to downloaded music/videos.
6. Please try with another device (phone/tablet/etc.) and see if the issue is the same.

What should I do if there is a delay between the earbuds and the device?
It's important to note that there may be a slight delay when using any type of Bluetooth audio device, which is a common limitation of Bluetooth technology. In most cases this delay is minimal and should not impact your experience. However, it's worth mentioning that the delay can be influenced by various factors such as the
Bluetooth audio device itself, the connected device, the audio source, the specific application being used, and even the network conditions.
To fix this issue, please try the following:
1. "Forget" the earbuds in your device's Bluetooth history. Reboot your Bluetooth device such as your phone or computer.
2. Make sure the charging case has enough power, and reset the earbuds as per the steps below:
- Place the earbuds in the charging case and leave the case open.
- Press and hold the reset button on the charging case for 10 seconds until the LED indicators on the charging case start to scroll and then stay on for 5 seconds. At this time, your earbuds have been successfully reset.

When resetting the earbuds, make sure the earbuds are well properly connected to the charging case, or it may cause the reset to fail. When you place the left and right earbuds in the charging case, there will be white LED indicators in the charging case which confirm the earbuds are properly connected to it.

If the indicators in the charging case don't light up, please check whether the charging case and earbuds are properly connected, have enough power, and clean the charging pins with a dry cloth.

3. Test your earbuds with a different Bluetooth device, app, and/or downloaded music/videos to see if the problem still persists.
4. Make sure the Bluetooth device and earbuds are within Bluetooth range, and there is no signal interference between them.

What should I do if I experience sound leakage?
First and foremost, the open-sound headphones are designed to deliver a more natural and expansive soundstage, coupled with a comfortable wearing experience. This design permits some ambient noise to seep in, allowing you to stay aware of your surroundings while indulging in your music. This feature proves particularly useful for outdoor activities or situations where it's crucial to be mindful of environmental sounds.

However, a byproduct of this design is the "sound leakage" issue. It's not a flaw in the product's quality, but rather a natural occurrence associated with the open-sound design. This might result in others hearing some sound at high volumes, but under normal volumes, this should seldom happen.
