Industry-leading Digital Noise Cancellation1
Everything in the WF-1000XM4 headphones has been redesigned from the ground up. Like our new Integrated Processor V1, specially developed by Sony, that cancels more noise than ever, a new driver with more performance, newly designed noise sensing microphones, and innovative Noise Isolation Earbud Tips with a more stable fit.
Integrated Processor V1
Specially developed by Sony, our new Integrated Processor V1 takes the noise canceling performance of our acclaimed QN1e chip and goes even further. Improved noise canceling performance and Bluetooth 'System on Chip' technology delivers the industry's highest level of noise canceling yet uses less power.
High-performance dual-noise-sensor microphones
Two noise sensing microphones per earbuds – one forward-facing and one backward-facing – catch more ambient sound around you. This means more stable noise canceling and less distortion at any volume.
New 6 mm driver unit
A newly designed 6 mm driver unit, featuring a 20% increase in magnet volume, gives you improved performance in low frequencies. It also enhances noise canceling 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.
Minimizing wind noise
Even on windy days, you'll stay totally immersed. Automatic Wind Noise Reduction mode detects when it's windy and automatically suppresses wind noise for more effective noise canceling.
Exceptional sound quality
The WF-1000XM4 support 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 LDAC codec processing and DSEE Extreme.
Enjoy High-Resolution Audio without wires
The WF-1000XM4 support High-Resolution Audio Wireless3, 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.5
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. 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.
Beamforming microphones pick up every word
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.
Detects speech vibrations to enhance clarity
A bone-conduction sensor picks up vibrations from your voice without registering ambient sound, enabling even clearer speech when making calls.
Smarter talking, smarter listening
As soon as you speak to someone, Speak-to-Chat automatically pauses the music and lets in ambient sound so you can conduct a conversation7 – handy if you want to keep your headphones on, or if your hands are full. And once your chat is over, your music starts playing again automatically.8 Speak-to-Chat uses an acceleration sensor to recognize and react to your voice. It is based on Precise Voice Pickup Technology, which combines four microphones and sensors with advanced audio signal processing.7
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 hours6 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%.
Water resistant for everyday use
With an IPX4 water resistance rating2, splashes and sweat won't stop these headphones – so you can keep on moving to the music.
Easy wireless charging with Qi technology
No cables necessary – the WF-1000XM4 feature Qi technology for easy wireless charging.4 You can even use a smartphone with Qi technology, like the latest Xperia models with reverse wireless charging, to charge your headphones and charging case.
With the Sony | Headphones Connect app, Ambient Sound Control lets you adjust the volume of background sound and gives you the option to allow voices alone to be heard. Meanwhile, the Equalizer lets you customize sound levels to suit your music.
Ergonomic surface design for a better fit
Since introducing the world's first in-ear headphones in 1982 (MDR-E252), we've surveyed huge amounts of data relating to ear shapes from around the world. The WF-1000XM4 headphones are the product of that research, combining a shape that matches the ear cavity with a new ergonomic surface design for a more stable fit.
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.
Instant pause. Instant play.
Just take the earbuds out of your ears and the music stops – a proximity sensor knows when you are wearing one or both earbuds. Pop the earbuds back in and the music starts again.
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 Canceling 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.
Easy pairing with your computer
Swift Pair makes it quick and easy to pair your WF-1000XM4 headphones with your Windows 10 laptop, desktop PC or tablet. Pop-up pairing guidance appears on nearby Windows 10 devices when pairing mode is selected.
Get hands-free help. Just say "Hey Google" or "Alexa" to activate your preferred voice assistant.9 You can manage your day and even control your headphones with commands like "Turn off noise cancellation" 6
