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 V1Specially 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 microphonesTwo 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 unitA 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 TipsNewly 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 noiseEven 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 qualityThe 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 wiresThe WF-1000XM4 support 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 filesUsing 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 wordBeamforming 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 clarityA bone-conduction sensor picks up vibrations from your voice without registering ambient sound, enabling even clearer speech when making calls.Smarter talking, smarter listeningAs 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 yourheadphones 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 minutesYou 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 play time and the Sony | Headphones Connect app will even notify you when your charging case drops below 30%.Water resistant for everyday useWith 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 technologyNo cables necessary - the WF-1000XM4 feature Qi technology for easy wireless charging.

Meanwhile, the Equalizer lets you customize sound levels to suit your music.Ergonomic surface design for a better fitSince 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 signalThe 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.

Used Sony WF-1000XM4 Truly Wireless Noise Canceling Earbuds, Black undefined

I received these as a gift a couple of years ago and they were great. Now I can't go more than a minute and the left ear bud says the battery is drained...which it's not...and it disconnects. Super disappointing as I know these aren't cheap (well cost wise anyway). I wouldn't recommend. I can't use them anymore. This isn't just my problem..I see many people have this issue. Sony should replace them.

Junk

The earbuds claim to be fully charged but now only last 15-20 minutes. Bluetooth connectivity is average and does tend to disconnect often. The app is horrible to use. However, the audio quality is good.

Poor Battery Life

These worked well but did not have the promised best sound. After not using them for some time for fear they would be lost as they never fit properly, even with the earpads provided, I decided to give them another try. 
After fully charging them with the provided cords the, the left ear dropped the charge within minutes (100% to 0% in under 5minutes). Went online and read that it might be a firmware issue. Tried updating to the latest but was unable to do it in one try because of the draining battery. When I was able to finish the update, the battery went from 60% left and 75% right to 0% both. Even after resetting the battery now drains not in 5 minutes but on the left, almost immediately, on the right I may get 10 minutes out of it. Very saddened by this as they are expensive and seem to work poorly, much more so than the cheaper Monsters I wound up buying to replace these.

Great Until Not Great

After 18 months the battery fails and the earbuds will not charge. You may as well purchase a far cheaper option.

Poor battery

I originally purchased these earbuds January of 2023. They were excellent and lasted very long even with prolonged use. But that changes when a firmware update rolled out and caused damage to the battery life of the earbuds. Now when fully charged they barely last an hour and the drain is unequal for each earbud. 

Since this happened after my warranty period there's nothing I can do. It's a shame because they were a quality pair of earbuds.

Excellent until a firmware update

I'm not going to rehash everything that has been written online about these earbuds. Suffice to say, a firmware update by Sony has all but rendered these earbuds useless. Battery in the case and right earbud deplete fully in about 2 1/2 hours. Battery level in the left earbud still has plenty of power.
Sony may have got their wish to ensure users buy a replacement. I will - but they will definitely NOT be made by Sony.

Waste of money

Great phones until a sony firmware update ruined the battery of the left earphone. Now sony want me to pay their repair. Customer service is useless.

Great earphones until sony messed up firmware

I purchased these earbuds about a year ago. They sound great and fit nicely in my ear. The look of them is classy. There is an app you download to pair the earbuds to your phone. The downside is that if you are unable to access that app via internet or wifi you may not be able to connect them to a new device. They dont have a pairing button on the case so the app is a must. I took a flight and was unable to connect them to another device because they were not previously paired, rendering them useless. Im also already having major issues with them holding a charge, one earbud draining as much as 80% within 30 minutes. Im performing another software update which will take about 30 minutes to complete so we will see if that fixes the problem!

Mixed feelings

This product cost 180£ and in less than 2 yrs the batteries are kaput . Sony should have at least offered a trade in against new ones as they knew there was an issue with these expensive headphones

Great but terrible sony support

Had to send both pairs I bought back in October of 2024 cause of a charging issue. BOTH my husbands and my case and headphones were getting hot during charging. They gave us both a new pair, after 4 months the left earbud started making a wind noise when it was on noise canceling or ambient sound. Didn't make it when those were turned off. I take great care of them, they have not been dropped or beat up in anyway. Honestly makes the earbuds worthless since I can only wear one now. The whooshing noise in the left ear bud is enough to drive you crazy. These earbuds have been way more trouble than they were worth. It sucks that they only have a one year warranty because my husbands, mine and others I know that have this model, they started having issues shortly after the year. It's almost like they degrade in quality after some updates, so that you have to buy new ones.

Too many issues for what they are worth

After reading many reviews I went ahead and bought these headphones in November 2021. The sound quality and noise cancellation is excellent. I have really only used them while travelling which is not too often. When I got them the fully charged batteries indicating 100% would last up to 6 hours before needing a recharge or top up from the charging case, ideal for most travel destinations within Europe. I used them on a flight to London last September and noticed a big deterioration in the battery life. Thinking I did not charge them properly I fully charged them for a recent 4 hour flight and got approx 2 hours usage before they needed a recharge. I have to say I am very disappointed with the life span and reliability of these headphones considering they were bought from a very reputable retailer and were not cheap. I acknowledge that they are outside the warranty period but considering the little use they have had I would expect a far greater life from them. I have been in touch with Sony customer service and unfortunately because the warranty period is up I would need to pay for a chargeable repair. I will conclude by saying don't leave them in a drawer waiting on the next flight make sure you use them a lot during the warranty period in case any problems develop that way at least you will be covered. Very disappointed.

Very disappointing battery life.

Wouldn't buy again, always trusted Sony products to last the test of time

Battery died after 2 years

These were great for about a year. Now the right ear bud has next to no battery life. Won't charge passed 80% and will go from 80% to 10% in 15 minutes. The last 10% will only last about 2 minutes before it "dies."

DO NOT BUY!!

Unfortunately I was looking forward to have them.cos I love sony brand and have few of ur products but this one was Unfortunately full miss... sound is great noise cancellation superb battery very bad holding only 30 min and need to recharge case holds only for 2 recharges ... and had to return them ... shame

Great sound but battery...

The battery will drain really quickly on the earbuds. Even if you start with fully charged earbuds, using them for 5 minutes will drain it down to zero and turn it off. This is very frustrating!

Battery drains quickly!

Won't stay in your ears. Great sound quality, buy they missed the mark by not designing them to stay in your ears. Not worth a purchase

Won't stay in your ears!

Although all the reviews online say "Buy these if you can't afford the XM5 model", don't buy them. One little firmware update and they're useless. The Left Ear battery life drops to about 15-20 minutes. This is by far and away the worst purchase of Sony equipment I have ever made in my life.

Abysmal battery life

Left earbud exploded while in case. Very loud pop, blew case top open and the earbud had separated. Chemical/burn smell and a connection severed.

Earbud exploded on my desk

The battery drains quickly, especially in the left earbud which lasts less than 10 minutes. The headphones don't fit properly in your ears, and initially, I thought this was just the future design. However, even if you walk a little fast, they fall out of your ears. Reaching customer service is difficult, and for this price, I expect them to last longer or have additional service centers for repairs. However, I'm not sure about the cost yet.

Battery drain and won't properly fit in ears

Great sound and features. Comfortable fit. Totally let down by batteries. They now only last about 20 minutes. Read that it could possibly be software so have updated but still have a terribly frustrating product. I have now gone back to using wired headphones.

Great sound but..

These headphones sound absolutely great but just be prepared to buy another set within a year and a half or so after the warranty expires the battery drain is significant and they are almost useless. Probably get 20 minutes out of a full charge if that and I have another pair of Sony earbuds. That does the same thing. Please do not buy these products

Rapid battery drainage after 16 months of use. Gar

Bought these earbuds nearly three years ago and the right earbud drains slot quicker than the left. I absolutely loved these earbuds when I bought them. They replaced the Sony WF-XB700 only purely because they weren't compatible with the Sony connect app. I still have my XB700 and they still to this day hold their charge I think they're nearly 5 years old at this point. Also I was disappointed with the volume level out the 1000XM4 so had to use a third party app to boost the volume. It's such a shame for expensive earbuds to not last even 4 years is disappointing. I'm afraid if I upgrade to the WF-1000XM5 will I be here in another three years with the same issue?

It only happened after the last update the buds got. Everything was ok up to that point. I don't know if an update can fix them however if it does fix them I'll update my review.

Just very unhappy now.

After nearly 3 years they're caput

I bought this in Nov 2021. It worked fine for about 8 months then had issues with the battery. The left side drains so quickly that only lasts for 10 minutes. Then I contacted with technical support and they agreed to replace it in Sep 2022. Now, the same issue happens again. The left earbud only lasts less than 20 minutes and when it's charging, it gets really hot with red flashing on the case. I can feel that when I put in my ear and I doubt if it's safe to use it.

This is definitly a defective product!

I just registered these after 3 years. I have used them for a while now. The earphones when working correctly are amazing.

However poor hardware, construction or the various (and most likely latest) firmware updates (currently v2.1.0) have rendered my earphones almost unusable. The battery drains from both buds inside 45 minutes. Sony have said I'll have to pay to get them fixed at an unknown cost.

You can also not downgrade the firmware, therefore stopping you from fixing them yourself.

Shocking really, near enough £200 for under 3 years use.

Sound is great, software is horribly bad

After about a month the ear plugs began disintegrating and now after four years the lefthand bud will not hold a charge.

Ear buds And battery issues

Bought 1 for myself and another for my wife. Both started developing battery problems within a year, and 1 became unusable at around the 2 year mark, outside of warranty. Since this happened to both pairs, i doubt the quality of the batteries used

Batteries dont last

Had them replaced two days ago and now perform as expected.

Great devices, Finally fixed

Listen ??! (pun intended).When i tell you it's Feb 2025, i decided to pull these things out the drawer, and completely fell back in love. These are hands down the best earbuds ever. I don't even feel the need to upgrade, theyre just that good to me.

Top Tier Quality

I was given these headphones in November 2022. For an year and half they worked well without any issues. After some software updates, I have noticed that the battery was lasting way less, but I could still used the headphones. In the Past 6 months the battery condition has decreased, and now I just can't use the headphones because the battery does not last more than 10/15 mins which is unacceptable. This was clearly a problem caused by Sony and they should have resolved it. I have added some screenshots of the battery that highlight this problem.

Batery Drain after software update - Do not buy!!

,

I am writing to report a battery issue with my Sony WF-1000XM4 earbuds. Despite following all recommended maintenance steps, the battery depletes within 20 minutes of use, making them nearly unusable.

To troubleshoot the issue, I have already:

1. Cleaned the earbuds thoroughly.

2. Updated the software to the latest version.

3. Shut down the Ambient Sound Control feature.

However, none of these steps have improved the battery performance. Given that these are premium earbuds, I am disappointed by the rapid battery degradation.
I would appreciate guidance on possible solutions, including a repair or replacement if covered under warranty.

Please advise on the next steps at your earliest convenience.

Sincerely,
Vikram saini
