Oneodio ANC Headphones
Noise always made us crazy when enjoying the audio. Luckily, the Oneodio finds the audio nirvana and makes its active noise cancelling headphones. Oneodio stunning Bluetooth headphones offers incredible noise cancelling features and crystal-clear sound to effortlessly keep up with your urban and outdoor lifestyle.
Active noise control (ANC), also known as noise cancellation, or active noise reduction (ANR), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first. Noise cancellation makes it possible to listen to audio content without raising the volume excessively. Active noise-canceling headphones can do everything that passive ones can do — their very structure creates a barrier that blocks high-frequency sound waves. They also add an extra level of noise reduction by actively erasing lower-frequency sound waves.
