Sony WH-1000XM4 is currently one of the best in its class (or even the best) full-size wireless headphones with active noise cancellation system. This is a rare case when a producer does not have to develop a model from scratch with each generation, but to improve once again the already very successful existing one. Which, by the way, is not so easy. In the new model Sony has expanded the functionality of the headphones and added a number of convenient things. In particular, auto-pause when you take off the headphones or start a dialogue. Also, the headphones have the ability to pair with two devices simultaneously and got an updated technology DSEE Extreme to improve the compressed audio materials. Sony WH-1000XM4 is still easy to use, sounds good and can live on a single battery charge for a long time. There are only a couple of small things and it is probably unfair to say that they are reasons not to buy the model. First of all, there is no support for aptX and aptX HD codecs. But, almost all modern Android smartphones support LDAC, so it’s actually not a problem. Secondly, they are not waterproof.

What’s in the box?

The contents of the package have not changed at all since the last generation. The Sony WH-1000XM4 come in a large beautiful box with lots of printing. Inside you’ll find a hard travel case, which contains everything else, i.e the headphones themselves, a Type-C USB charging cable, a 1.2 meter audio cable for wired connection, an adapter for an aircraft and documentation.

What is New Compared to Sony WH-1000XM3?

It is quite difficult to distinguish Sony WH-1000XM4 from Sony WH-1000XM3 by appearance. In general, the design is very similar. The main changes affected functionality of Sony WH-1000XM4.

• In the model WH-1000XM4 there is a wearing detection sensor, through which headphones can automatically pause and resume playback when you take them off and on.
• It uses the same Sony QN1 chip as the previous model, but the algorithms have been improved. And it is claimed that the noise cancellation works even better. At the same time, the customization for a specific user needs and the wearing conditions of the headphones have been preserved. As well as different scenarios depending on the current actions and location.
• In contrast to Bluetooth 4.2, Bluetooth 5.0 is now used and it is possible to connect to two devices at the same time (but it does not work if LDAC is used).
• The list of supported codecs includes SBC, AAC and LDAC. This means there is no support for aptX and aptX HD. I don't consider this a problem, and I explain why below.
• Speak-to-chat technology automatically reduces volume during conversations. Having heard the voice, the headphones automatically stop the music and restore the playback after a set interval after last words.
• There is support for 360 Reality Audio (Virtual Surround Sound) format, the corresponding records are already available, including streaming services of Deezer and Tidal. Also the manufacturer claims to have better microphones on the new release.
• WH-1000XM4 have the DSEE Extreme sound enhancement technology, which replaced the older DSEE HX feature.
• The microphones are better at capturing voices.

What does Sony WH-1000XM4 Look Like?

Externally and structurally Sony WH-1000XM4 are not much different from the previous headphones. What we think is a benefit in this case: the headphones look very stylish and expensive. Matte plastic is primarily used in the design, no gloss. The coating itself resembles soft touch, but in reality it is not. In any case, Sony WH-1000XM4 do not collect any fingerprints. The model is available in two colors: black and silver.

Cups are of medium size, they do not look big on the head. On the front panels of cups there is practically nothing, just a small NFC stamping on the left side, and on the perimeter - microphone holes. In the previous version NFC sign was printed. The decorative elements are the golden SONY logo on the cups in the place of attachment to the headband and a little lower - the same golden edging around the microphones of the noise canceller.

The headband design is standard, with sliding mechanisms for size adjustment and a metal inner frame for strength. The upper part of the headband is upholstered with artificial leather, and with foam filler on the inside. Left and Right marks are placed on the inner part of the headband next to the cups.

The design allows the cups to be turned to hang comfortably around the neck when not in use. Sony WH-1000XM4 is also foldable and fits well in a compact travel case.

The earpads are also made of artificial leather, inside - fabric. They are quite wide, deep and very soft. Inside the left cup there is a Wearing Detection Sensor, thanks to which the headphones automatically pause when removed and resume playback when on again.

There are not so many functional elements on the headphones. On the left headphone there is a 3.5 mm jack for wired connection and two buttons, power button with LED and the so-called Custom button, the action of which can be configured via application. By default you can control the ambient sound. A short press switches the modes of noise cancellation, and a long press starts its optimizer. On the right earpiece only USB Type-C is visible. The rest of the control is done using the touch panel on the right cup lid.

As for the quality of materials, assembly and appearance, there is nothing to complain about at all. These flagship headphones look appropriate. Perhaps users of the previous models may feel a little disappointment by almost no exterior differences. But, actually there is not much to add.

Is It Convenient to Use Sony WH-1000XM4? 

Sony WH-1000XM4 are compact full-size headphones with a decent headband size adjustment range and rather lightweight. We couldn't find exact data on the official website, but the previous model weighed 0,5 pounds (255 g). There shouldn't be any big difference with the new one. The size of cups and ear cushions allow the ears to be completely inside, and the headband tracking force is optimal. The headphones are not pressurized. You can wear them almost the whole working day (tested) without any discomfort or desire to take them off. As for the street, in summer, at +27 ° - +30 ° ears sweat. This is not critical and half an hour walk in the fresh air does not turn into hell. But, still, full-size headphones in general are not the best option for a hot summer. In any case, we haven't yet met any models where ears don't sweat in the heat. It is important to use artificial leather to ensure good sound insulation. A more "breathable" fabric is not suitable for this.

The connection is carried out in a usual way: to switch to the pairing mode you need to press the power button and wait for the LED to flash, then - the usual procedure is already on your smartphone. The producer promises a stable connection at a distance of up to 33 feet (10 meters). The quality of the connection depends on a lot of factors, starting from the walls and ending with the total load on a radio channel. At a distance of 20-23 feet (6-7 meters) there was no failure observed. Let’s also look at peculiarities about codecs: SBC, AAC and LDAC are supported, aptX and aptX HD are not. And it’s not clear - why. But it is not a critical problem, as far as LDAC is available in the form of open source code and is included in the "standard set" of Android. In this case, the maximum bitrate can reach 990 Kbps. While the limit of aptX HD is 576 Kbps, and aptX/aptX HD should be licensed from Qualcomm. During the test, only the LDAC codec was used, its own audio library, approximately 95% of which is in FLAC. And as a streaming music service - Deezer HiFi with FLAC up to 1411 kbps. Of course, you shouldn't expect that absolutely all tracks on the service are provided in the maximum quality.

Control "on the go" is carried out with the touch panel on the right earpiece: horizontal movements are responsible for switching tracks, vertical - for volume control. Double touch - Play/Pause, as well as Receive/End calls. And if you cover the right cup with your hand, "attention” mode is activated to hear what is happening around. The control is intuitive and easy to understand. We haven't had any problems with touch control since the first launch. In the past there were complaints on the previous model regarding the sensor's operation in the cold weather, it’s reaction to moisture and condensation. SONY promises to improve the new model's sensor and battery.behavior in cold weather. We’ll see it soon.

Sony Headphones Connect App manages all the functions of Sony WH-1000XM4. It is divided into three tabs. The first one, called "Status", is not very functional. It displays battery power, a codec used, a current track and adaptive sound control.

The second tab "Sound" is much more interesting. In this tab you can adjust the noise cancellation level, speak-to-chat technology, noise cancellation optimizer, equalizer, 360 Reality Audio, sound quality mode (a choice between quality or stability of connection) and DSEE Extreme.

In the third tab "System" you can set up simultaneous connection to two devices, select the action of the Custom button (by default - ambient sound control, can be reassigned to Amazon Alexa or Google Assistant), disable the touch panel, set up auto-pause and auto-off, select the language of voice prompts and set up software auto-update.

Now about noise cancellation and adaptive tuning. In addition to the usual level adjustment with the slider through the application, there are three presetings between which you can switch on the headphones themselves with the Custom button (if you have not reassigned it to the voice assistant). They are full noise cancellation, selective and complete disabling of noise cancellation. The adaptive sound control automatically adjusts itself to the current situation, including geolocation. And for every such situation you can adjust the level. For example, maximum level if you are in public transport and minimum level if you are outside.

There is also a user-specific optimization function and an external pressure level. The function is not new, it was also present in previous models. The application asks to place the headphones in a usual position, then headphones begin to emit sounds at different frequencies, which are read by the appropriate microphones inside the cups. Further, based on a bunch of factors (including even presence of glasses) the algorithms optimize the noise reduction system under specific conditions.

To set up 360 Reality Audio, the application asks the user to take pictures of his ears, and then automatiсally adjusts everything to the specific user. The next step is to configure applications. Deezer, Nugs.net and Tidal have content in 360 Reality Audio format. 

What about Sound and Microphone Quality?

If you consider the category, target audience and price range, Sony WH-1000XM4 sounds very good. The headphones have outstanding features in comparison with their closest competitors. For example, Bose QuietComfort 35 II sounds more flat. Bowers & Wilkins PX7 sound smart, but they are behind Sony WH-1000XM4 in noise cancellation. If we go back directly to sound quality, it seems that Sony was trying to please the widest possible audience. The headphones have a very nice V-shaped frequency response, without extremes. Lower frequencies are slightly accentuated, dense and massive. They give the sound the necessary weight and drive. They are not super detailed and fast, but everything is very good. The average frequencies are not "drowned", with enough amount. They sound quite natural, balanced and with good details. Live instruments and vocals sound nice. The upper frequency range sounds the same as it should sound in good quality headphones with a scope for the mass audience. There are enough of them, there is a slight rise, but the "dangerous" part of high frequencies is softened. Thanks to this, there are no symbilants and high frequencies do not grate on you. In general, Sony WH-1000XM4 sounds pleasant, but it is not a music fan level. Modern pop music and electronics sound best on the headphones, as well as instrumental genre. 

Now a few words about 360 Reality Audio. On personal sensations, it works approximately the same as the virtual surround sound in gaming headsets. We have tested them with Deezer 360. In general, it sounds very good and interesting, adding a kind of “Being There” effect. Personally, old jazz like Miles Davis sounds great.

Judging by design, three microphones on the left earphone are used for voice transmission. They do not cope with their main task perfectly, but quite well. In noisy places the other person hears the surrounding noise, but the voice is not lost and the information is heard. Even speaking in the subway, the partner did not have to ask again. In terms of quality of the sound transmitted - no surprises: the voice sounds flat and quite deaf, with no detachable microphone in all models.

How Good is Noise Cancellation?

To cut off external noise effectively it is not enough for headphones to have just an active noise cancellation system. The headphones themselves should have good sound insulation. Sony WH-1000XM4 is perfect with both, the ear cushions fit tightly to the head and provide good "protection" from external sounds. The Active Noise Cancellation System worked perfectly in previous models as well. But the new Sony WH-1000XM4 perform fantastic. They almost completely cut off the listener from surrounding sounds, especially monotonous hum at low frequencies. In closed spaces like offices they provide almost complete silence, and the hum of the subway can only be heard if you pause music. And it is not even hum, but something more like a distant rustle. So no external noise prevents you from listening to music under any circumstances. At the same time, maximum level of noise reduction does not create an unpleasant feeling of vacuum.

Battery Life

Sony states WH-1000XM4 can run on a single charge for up to 30 hours with noise cancellation enabled and up to 38 hours without noise cancellation. But it's worth considering that these data are valid for medium level volume and with SBC codec. During the test we only used LDAC and the volume level was around 70-80%, with an average working time of 3-4 hours per day. As a result, we did not manage to discharge them in a week, so battery life is very good. Fast charging is supported. 10 minutes of charge is enough for 5 hours of work.

• Can work in passive mode

Check Price

Bose QuietComfort 35 II delivers balanced sound and offers three noise canceling modes. If you want to hear some ambient sounds, you can set ANC low level or disable this function completely. In High mode headphones remove most of the external noise, although Sony's flagship model is still better in this regard. During audio and video calls you will not be asked to repeat what you have said, the built-in microphones perfectly capture voices. The Bose QC35 II does not put much pressure on your ears and is suitable for long wearing. The battery life lasts up to 20 hours. Fast 15 minute charging gives 2.5 hours of work. The only drawback is the old Micro USB port. If there is no power source nearby, you can connect the cable and listen to music in passive mode.
