Sony WH-1000XM4

Advanced noise reduction system Whether you are flying on a long trip or relaxing in a cafe, the WH-1000XM4 headphones will perfectly suppress noise and transmit high- and medium-frequency sound as efficiently as possible. Technology that gives new opportunities The Dual Noise Sensor technology captures ambient noise using four microphones on the headphone bowls and transmits data to the QN1 HD processor, which performs noise reduction in real time, taking into account the acoustic characteristics of the environment. With a new single-chip audio system and Bluetooth support, it evaluates the parameters of music and noise at a frequency of 700 times per second, the acoustic characteristics of the space between the speakers and the auricles and adjusts the sound signal accordingly. How to set up noise reduction Two developments are used for the most effective noise reduction in the WH-1000XM4 headphones: the technology of personal noise reduction optimization and the atmospheric pressure optimization function, designed specifically for airplane travel.
