Active Noise Control (ANC), Active Noise Cancelling (ANC), and Active Noise Reduction (ANR) are methods used to reduce unwanted sounds by introducing another sound designed to cancel them out. Our active noise-canceling earbuds employ a microphone to capture the sound, and a speaker to generate a phase-shifted sound that counteracts the original sound.
The charging case comes with its own battery, guaranteeing that the earbuds are always fully charged when you need them. For those using the earbuds solely for sleep, charging the case just once a week is enough, and it only takes about 3 hours to complete.
The sales package includes a charging cord, although it doesn’t include a wall plug. However, the provided charging cord is universally compatible, meaning it can be used in any country regardless of the electrical output. Moreover, the charging cable is designed to adjust power to the appropriate level, making it convenient to charge the earbuds smoothly from any location.
There’s no need for a noise-cancellation adjustment setting. The earbuds automatically minimize noise to the maximum extent possible at all times.
The QuietOn earbuds are designed exclusively for sleep, without any connectivity features or emission of electromagnetic radiation. As a result, our products are not meant for music playback, cannot connect to smartphones, and do not produce any additional noise, such as white noise.
QuietOn cannot alleviate tinnitus because it’s not an external noise but rather an internal error signal within the head. However, the effective noise reduction provided by QuietOn earplugs can act as a preventive measure against the development of tinnitus.
