Variations

The SONY/ WH-1000XM4 is a wireless headphone with an industry-leading noise cancellation function that has been further evolved. Equipped with DSEE Extreme that incorporates AI technology, you can enjoy high-resolution sound quality from various compressed audio sources such as CDs, MP3s, and streaming.

■ Industry-leading noise canceling performance that has evolved even further
・ Equipped with a new algorithm that further enhances the performance of the proprietary ""High-quality noise canceling processor QN1"". Compared to previous models, the cancellation performance for mid-to-high range noise has been further improved. You can immerse yourself in music in a quieter environment, not only in noisy environments such as airplanes, but also in environments with a lot of people's voices such as in the city or in a cafe.

■ Equipped with DSEE Extreme incorporating AI technology, compressed sound sources can also be high-resolution class high-quality sound
・ Equipped with DSEE Extreme that realizes even more realism by incorporating AI technology. You can enjoy various compressed sound sources such as CD, MP3, and streaming with high-resolution class high-quality sound. In addition, since it supports LDAC, you can enjoy high-resolution equivalent sound quality wirelessly, and you can also enjoy high-resolution listening with a wired connection using the included cable.

■ ""Speak to Chat"" function and ""Adaptive Sound Control"" function to create the optimal listening environment
- Even while listening to music, the new ""Speak to Chat"" function allows you to pause music playback and switch to ambient sound capture mode just by speaking when you want to talk, and the ""Adaptive Sound Control"" function switches to the noise canceling / ambient sound capture setting and equalizer setting registered in advance in conjunction with the user's behavior and location, automatically realizing the optimal listening environment according to the scene.

■ Comfortable fit and long battery life even for long periods of listening
- The soft ear pads and ergonomic design make it comfortable to listen to music for long periods of time. With noise canceling ON, it has a long battery life that allows up to 30 hours of music playback. It also supports quick charging that allows 5 hours of playback with 10 minutes of charging, so you can rest assured even if you suddenly go out.

■ Realizes even higher quality hands-free calls
- Hands-free calls are possible with smartphones, iPhones, and PCs. High-precision voice pickup technology optimally controls five microphones and performs advanced audio signal processing to deliver clear voices even in noisy environments. ■Industry-leading noise canceling performance that has evolved further
・The performance of the proprietary ""High-quality Noise Canceling Processor QN1"" has been further enhanced, improving noise canceling performance
・Equipped with ""Dual Noise Sensor Technology"" that accurately captures noise
・""NC Optimizer"" that optimizes the noise canceling function according to the user's wearing condition and environment
・""DSEE Extreme"" that incorporates new AI technology to bring high-resolution class (＊1) realism to any sound source
・LDAC compatible for enjoying high-resolution sound quality even wirelessly
・The DAC and amplifier built into the ""High-quality Noise Canceling Processor QN1"" express high-quality sound even wirelessly
