What is QuietOn 4?
QuietOn 4 is an autonomous active noise cancelling earplug device specifically designed for sleep. Unlike conventional headphones, this device does not stream audio, lacks Bluetooth connectivity, and requires no mobile application to operate. It uses high-precision microphones to sample ambient noise and generate phase-opposition waves to attenuate low sound frequencies. The system combines this active technology with passive noise reduction using memory foam ear tips. The device is designed to be worn all night, including by side sleepers, due to its compact and ergonomic shape. It is powered by a dedicated charging case that provides weekly autonomy depending on usage.
