Advanced Noise Cancelling System
A high sensitivity in-ear sound sensor, 11mm oversized driver, and an innovative noise isolation chamber work in tandem to detect and cancel out up to 98.5% of noise.
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.
11mm Oversized Driver
Features a unique curved design and specialized material to counter louder ambient noises.
Noise Isolation Chamber
Carefully designed to work alongside the custom-made driver to reduce distortion, so opposite sound waves repel noise more accurately.
