Description
Advanced noise cancelling—now even better
Everything in the WF-1000XM4 headphones has been designed from the ground up. Like our new Integrated Processor V1, specially developed by Sony, which cancels more noise than ever, a new driver unit with better performance, noise-sensing microphones and innovative Noise Isolation Earbud Tips with a more stable fit.
Exceptional sound quality
The WF-1000XM4 now supports High-Resolution Audio Wireless. 1 Thanks to specially designed 6-mm 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 LDAC codec processing and DSEE Extreme.
Integrated Processor V1
Specially developed by Sony, our new Integrated Processor V1 takes the noise cancelling performance of our acclaimed QN1e 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.
High-performance dual noise-sensor microphones
Two noise-sensing microphones per ear—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.
New 6-mm driver unit
A newly designed 6-mm driver unit, featuring a 20% increase in magnet volume and the high-compliance diaphragm, gives you improved performance in low frequencies. It also enhances noise cancelling by generating a high-precision cancellation signal to the low frequency range.
Noise Isolation Earbud Tips
Newly developed Noise Isolation Earbud Tips feature a unique polyurethane foam material. Soft and elastic, it maximizes 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 the WF-1000XM4 headphones easy to wear.
Enjoy High-Resolution Audio without wires
The WF-1000XM4 now supports High-Resolution Audio Wireless2, thanks to LDAC, our industry-adopted audio coding technology. LDAC transmits approximately three times more data (at the maximum transfer rate of 990 kbps) than conventional Bluetooth® audio, allowing you to enjoy High-Resolution 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-AI (Artificial Intelligence), DSEE Extreme™ (Digital Sound Enhancement Engine) upscales compressed digital music files in real time.3 Dynamically recognizing 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.
Listen all day, charge in minutes
You can enjoy a full working day of charge—8 hours—from your headphones and store another 16 hours in the case. That means a full 24 hours2 of listening time every time you leave the house. In a hurry? 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%.
Easy wireless charging with Qi technology
No cables necessary, the WF-1000XM4 feature Qi technology for easy wireless charging.3 You can even use a smartphone with Qi technology, like the latest Xperia model with battery share function4, to charge your headphones and charging case.
Everything’s at your fingertips
The WF-1000XM4 headphones feature intuitive touch control settings—for example, tap on the left earbud to change from Noise Cancelling to Ambient Sound and long tap for Quick Attention, or double tap on the right to skip to the next track. What’s more, you can assign your own functions to each earbud using the Headphones Connect app.
A clearer, more stable Bluetooth signal
The optimization 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.
