Sony Wireless Noise Cancelling Headphones SM Silver Alexa Audio Up to 30 Hours Continuous Playback Headphones with Microphone [Refurbished] WH-1000XM4

Improved noise cancellation performance thanks to an advanced algorithm. Cuts 20%* more everyday noise than the previous model. The algorithm has been improved with the addition of a high-performance new chip. Adapts in real time with high precision to music, noise, and acoustic characteristics. Further evolved high-quality sound design ~DSEE Extreme~ DSEE Extreme, powered by AI-driven deep learning, analyzes music in real time and upscales it to the optimal sound. LDAC transmitted audio sources and DSEE Extreme upscaled audio sources can also be adjusted to your preferred sound with the equalizer. The "Speak to Chat" feature allows you to have conversations without removing your headphones, and it also lets in ambient sounds depending on the situation. Adaptive Sound Control AI automatically switches between noise cancellation and ambient sound modes based on the user's behavior, selecting the preferred noise cancellation or ambient sound mode based on the user's frequently visited locations. It supports a wear detection function that stops music playback simply by putting on or taking off the headphones. Lightweight design and optimized side pressure/ear pad contact area ensure a comfortable fit even during extended use. ■Industry-leading noise-canceling performance that has evolved even further Equipped with a new algorithm that further enhances the performance of our proprietary "High-Quality Noise Cancelling Processor QN1," this new model offers improved noise cancellation, particularly in the mid-to-high frequency range. This allows you to immerse yourself in music in greater silence, not only in noisy environments such as airplanes, but also in environments with many people, such as city streets and cafes. ■ Equipped with DSEE Extreme, which incorporates new AI technology, compressed audio sources can now be transformed into high-resolution audio. Equipped with DSEE Extreme, which incorporates AI technology to deliver an even more immersive experience, you can enjoy various compressed audio sources such as CDs, MP3s, and streaming services with near-high-resolution sound quality. Furthermore, LDAC compatibility allows for high-resolution sound quality wirelessly, and the included cable enables wired high-resolution listening as well. ■ Newly added smart features to create the optimal listening environment It features numerous smart functions that automatically create the optimal listening environment for each scene, such as the new "Speak-to-Chat" function, which allows you to pause music playback and switch to ambient sound mode simply by speaking when you want to talk, even while listening to music, and the "Adaptive Sound Control" function, which switches to pre-registered noise cancellation/ambient sound mode and equalizer settings in conjunction with the user's actions and location.
