* How the Advanced Noise Cancelling System Works
Three elements work in tandem to detect and cancel out up to 98.5% of noise.
The 11mm oversized driver features a unique curved design and specialized material to counter louder ambient noises. The high sensitivity in-ear sound sensor picks up a wider range of sounds without distortion, so the algorithm can accurately identify and counter more types of external noises. The noise isolation chamber is carefully designed to work alongside the custom-made driver to reduce distortion, so opposite sound waves repel noise more accurately.
* Less Plastic for a Greener Future
Soundcore now use FSC-certified, 100% paper-sourced materials in their headphone packaging.
