The unique QuietOn provides you with peace through active noise cancellation and acoustic sound dampening. The QuietOn operates at the same level as the best on-ear noise-cancelling headphones. It boasts a battery life of 50 hours. Enhanced performance by reducing workplace distractions helps to lower stress. Replace uncomfortable ear protection with small, lightweight QuietOns. Simply switch off during exhausting flights and arrive at your meeting refreshed. Work efficiently on trains or planes. Sleep more soundly and better in hotels or next to your snoring partner. The noise levels in aircraft cabins are around 100 Hz. At this frequency, all passive earplugs fail. While they may provide broad-spectrum coverage, they do not address low frequencies. QuietOn combines both features: passive broad-spectrum noise reduction and active noise cancellation in the low-frequency range.
