The "high-quality noise canceling processor QN1" installed in the WH-1000XM3 is also installed in the neckband style. By enabling high-performance noise canceling processing, you can immerse yourself in high-quality sound without worrying about noise even in various environments. The noise collected by the two sensors (microphones) located on the outside and inside of the headphones and the player's music signal are all digitized. The DNC (Digital Noise Canceling) software engine integrates two methods of feedforward and feedback to generate highly accurate anti-phase sound that has the effect of canceling noise. Clearer music playback is now possible in a quieter environment. Supports a function that optimizes noise canceling performance according to changes in atmospheric pressure. It also provides a high quality noise canceling experience when used on an airplane. It is also possible to switch to "ambient sound (external sound capture) mode" where you can listen to the surrounding sounds while listening to music. It can also be used in scenes where you want to listen to music but want to pay attention to the surrounding sounds. It is equipped with technology that allows you to enjoy all kinds of music with high sound quality, from high-resolution sound sources to compressed sound sources. When connected to an LDAC compatible device, high-resolution content can be transmitted with up to about three times the amount of information of conventional Bluetooth Audio, so you can enjoy high-resolution content with sound quality that faithfully reproduces even the finest expressions of the original sound. Even if you do not have a high-resolution sound source or a high-resolution compatible terminal, you can enjoy high-resolution sound quality because it complements the high-frequency range of compressed sound sources such as CD sound sources and MP3s.
