soundcore C50i are open-back earbuds designed to keep you connected to your surroundings while providing a comfortable fit and a natural, spacious soundstage. This structure allows air and sound to flow freely, providing an unobtrusive fit and a high-fidelity experience. However, this also means that a certain amount of some sound leakage is unavoidable.

We recommend the following:

1. Set the volume to a level that suits your environment and listening needs.

2. Adjust the earbuds' angle for the best fit—the farther the sound outlet is from your ear canal, the more sound may leak.
