Amazing sound quality. Experience richer vocal sound and more detail thanks to the new Dynamic Driver X, a specially designed driver unit to reproduce a wide frequency spectrum. The diaphragm structure combines different materials for the dome and rim of the headphones, ensuring low distortion and clear sound quality. For less distortion, HD Processor for Noise Cancelling QN2e and Integrated Processor V2 have been combined to integrate precise 24-bit audio processing and powerful analogue amplification. The result is minimum distortion and crystal clear audio reproduction. Thanks to LDAC, our industry-recognised audio coding technology, the WF-1000XM5 support High-Resolution Audio as well as High-Resolution Audio Wireless. You'll also enjoy precise upscaling with these headphones. Using Edge AI (Artificial Intelligence), DSEE Extreme upscales compressed digital music files in real time, including those from popular streaming services. These Sony headphones are also certified for 360 Reality Audio. Optimise your listening experience by analysing your individual ear shape with the Sony Headphones Connect app for the optimal, immersive music experience.
