Product Information

Take the next step in truly wireless noise-canceling performance and exceptional sound quality. The new Integrated Processor V1 delivers unmatched performance while using even less power. Adding in drastically enhanced call quality, IPX4 water resistance, and up to 24 hours of battery life 6 with wireless charging, the WF-1000XM4 Truly Wireless Earbuds are unlike any other before them.

Industry-leading Digital Noise Cancellation

Everything in the WF-1000XM4 headphones has been redesigned from the ground up. Like Sony's 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 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 LDAC codec processing and DSEE Extreme.

Enjoy High-Resolution Audio without wires

The WF-1000XM4 supports High-Resolution Audio Wireless, 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. Dynamically recognizing the 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 conversation – 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. 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.

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 hours 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 playtime 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 rating, 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 features Qi technology for easy wireless charging. 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.

Customize sound

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), Sony has 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.

Voice assistant

Get hands-free help. Just say “Hey Google” or “Alexa” to activate your preferred voice assistant. You can manage your day and even control your headphones with commands like “Turn off noise cancellation”.

Ear tips starts breaking apart after a week's use
The memory foam ear tips start breaking apart after about a week's use - certainly not something you would expect after paying a premium price and the Sony quality you'd expect.

Expensive - all the more so when they don't work
Just bought these as my other wireless headphones were about to give up. But I guess I'll be using the old ones for a bit lnger as these new ones only work on my iPhone. I get them paired with other devices like my LG TV - but no sound so completely useless. Ther may well be a fix somewhere, but whe I pay for expensive stuff I expect it to play straight out of the box. Sony don't understand this - thehy seem yo think we have nothing to do but look for a fix. I'll juust send them back.

Better than expected!
I was hesitant as first on buying the XM4 since I have the XM3 which wasn't too great. I've had my XM4 for over 2 weeks now and love it. I also bought the Devialet Gemini before the XM4 was out. Put a deposit on the B&W PI7 as well and awaiting delivery. But after buying the XM4 I've cancelled the order for the PI7. Totally satisfied with my new XM4 now!

Sony wf1000mx4 wireless earbuds
I have a pair of mx3 and is very happy with it, particularly the sound quality and sound stage.
The mx4 fits my ear better and has some improvements on sound quality as well. Its app is second to none. I love it.

Unhappy with this product
I am very unhappy with this product, I actually put it aside and went back to the old XM3s.
1. The sound quality is incomparable to the XM3s
2. The harmonics and sonics are less than the XM3s
3. The bass that Sony is known for is lost with the XM4s
4. The buds are already ruined and unusable

Great sound, & stylish
I also owned M3, and this M4 is vastly improved in terms of stability, and this new shape design for much better into ears. Sound quality is much clearer during calls. Compared to M3, treble sounds more crispy while bass is more stable - clearly outperforms M3.

Defenitely true to the description!
I bought this last month and I'm truly happy with them, it does all it says on the description, they are very comfortable and don't hurt my ears after wearing them for a while! I've tried 3 different ones and all hurt. I don't have to remove them to talk and can walk with them and they don't fall. Haven't done any fast pace walk or exercise with them yet.
I recommend them for sure!

Almost Grandeur features
I bought it for 1 week and I found it rather great since the noise-cancelling were flawless. Moreover, the intelligent earphone features made life so much easier as you no longer needed to turn on ambient and noise-cancelling function manually since they were fully intellectually automatic.
