The advantage of open-sound devices is that they allow ambient noise to filter in, but the downside is that loud external sounds can overpower the audio from the earbuds, making it difficult to hear. You can adjust the volume of the earbuds accordingly for a better listening experience.

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.

It is recommended to use Spatial Audio for games and movies. Please use the default EQ or custom EQ settings for music.

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: - Try reducing the distance between your right earbud and your audio device, like having your audio device in your right pocket or right side.
