1. First, confirm whether this noise originates from the earbuds themselves, and if it persists after switching to Normal or an ANC mode.

If the noise disappears, it is caused by the capturing of ambient sounds in Transparency Mode, which is normal.

2. Transparency Mode amplifies surrounding ambient sounds to help you stay aware of your environment. This may result in faint background noise.

3. If it is a slight, persistent noise, this is normal. If the noise is loud enough to interfere with normal use of the earbuds, please contact customer service for assistance.

If you encounter any other issues or your issue has not been resolved, please contact us for further assistance.
