Sony WF-1000XM4 wireless noise cancelling headphone

• Specially developed by Sony, the new Integrated Processor V1 takes the noise cancelling performance of our acclaimed QNle chip and goes even further. 
• Improved noise cancelling performance and Bluetooth 'System on Chip' technology delivers the industry's highest level of noise cancelling yet uses less power.

• Two noise sensing microphones per side in Sony WF-1000XM4 wireless noise cancelling earphones - one feed-forward and one feed-back - on the surface of the headphones catch more of the ambient sounds of your surroundings, whether it's in-flight noise, city traffic or office chatter.

• Newly developed Noise Isolation Earbud Tips feature a unique polyurethane foam material. 
• Soft and elastic, it maximises the surface contact area between the earbud tip and the ear canal, eliminating gaps to insulate sound and reduce noise.
• It also improves adhesion to the ear canal for a more stable fit, making Sony WF-1000XM4 wireless noise cancelling earphones easy to wear.

• Sony WF-1000XM4 wireless noise cancelling earphones now supports High-Resolution Audio Wireless. 
• Thanks to specially designed 6mm drivers, they reproduce a dynamic sound despite their small size, and the high compliance diaphragm reproduces a rich bass range. 
• The Integrated Processor V1 also enhances sound, quality and reduces distortion, and enables LDAG codec processing and DSEE Extreme.

Enjoy High-Resolution Audio without wires

• LDAC transmits approximately three times more data (at the maximum transfer rate of 990 kbps) than conventional Bluetooth® audio
• Enjoy HighResolution Audio content in exceptional quality, as close as possible to that of a dedicated wired connection.

Real-time restoration of all your compressed files

• Using Edge-Al (Artificial Intelligence), DSEE Extreme Digital Sound Enhancement Engine) upscales compressed digital music files in real time. 
• Dynamically recognising instrumentation, musical genres, and individual elements of each song, such as vocals or interludes, it restores the high-range sound lost in compression for a richer, more complete listening experience.

• Precise Voice Pickup Technology uses beamforming microphones and a bone-conduction sensor to allow Sony WF-1000XM4 wireless noise cancelling earphones to pick up your voice clearly and accurately for hands-free calls — at home, in a café or wherever you are. 
• In addition, Noise Cancelling lets you hear the person on the other end of the call more clearly, even in noisy situations.

• Beamforming microphones are calibrated to only pick up sounds from your mouth. 
• With an improved signal-to-noise ratio they'll catch every word, even when there's a lot of noise around you.

• A bone-conduction sensor only picks up vibrations from your voice - it doesn't register ambient sound - enabling even clearer speech when making calls.

• You can enjoy a full working day of charge - 8 hours - from Sony WF-1000XM4 wireless noise cancelling earphones and store another 16 hours in the case.
• A full 24 hours listening time every time you leave the house.
• Just a 5 minute quick charge gives you up to 60 minutes of play time and the Sony|Headphones Connect app will even notify you when your charging case drops below 30%.
• No cables necessary, Sony WF-1000XM4 wireless noise cancelling earphones feature Qi technology for easy wireless charging. 
• You can even use a smartphone with Qi technology, like the latest Xperia model with battery share function, to charge your headphones and charging case.

• The optimisation of the transmission algorithm with the Integrated Processor V1 has made the connection more stable and less prone to sound skipping, even in an environment where there is interference. 
• It allows sound to be transmitted to both ears at the same time with very low latency, and with a higher signal strength than ever before.
