Sony WF-1000XM4: the TWO kings with noise cancellation and... how they sound!

Sony WF-1000XM4

Sony has just announced the arrival on the market of the long-awaited renewal of the truly wireless headphones that occupied its highest range. The WF-1000XM4 has been seen with a revamped design, eco-friendly packaging, a more compact box, and promises of better noise cancellation and Hi-Res sound quality.

The first thing we want to say is that we have received a unit to be able to analyze them and certainly Sony is making a remarkable effort in terms of removing plastics from its packaging. As we can see, we are dealing with a small box made of recycled cardboard.

Once we open this box we find directly the box of the headphones inside which are the same. Under that first platform, we have the silicone and foam heads for the headphones, a USB-C cable for charging the box but also charge wirelessly.

To use them we are guided to download the Sony Headphones application via a QR code. It is available for both iOS and Android and allows us to access all the possibilities offered by these headphones.

At first glance we are facing a clear redesign of them, being more compact and discreet. They have a design that achieves a better grip on the ear and is differential compared to most TWS wireless headphones on the market. It is available in black and white.

Sony promises better noise cancellation with this version of headphones thanks to the integration of a new processor, the Sony V1 that allows an improvement of up to 40% of the noise compared to the previous generation QN1e chip with lower consumption. This is also due to a redesign of the driver that has a more powerful magnet and helps in the cancellation of the most serious frequencies.

All this makes it possible for the headphones to work connected by Bluetooth 5.2 up to 8 hours with active noise cancellation and the box provides two additional loads, that is to say, a total of 24 hours of use.

If we leave the active noise cancellation disabled, that autonomy is extended up to 12 hours per charge so we would have a total autonomy with the two charges of the box of up to 36 hours.

The WF-1000XM4 mounts two high-performance microphones with noise sensors. Both signals are processed to achieve a great noise cancellation that is also improved with a new system of foam pads with a tunnel insulated.


This generation of Sony headphones can play Hi-Res music wirelessly thanks to the use of the LDAC codec that allows a transfer of up to 990 kbps. The integrated V1 processor uses processing technologies to enhance sound such as Edge-AI, DSEE Extreme™ 4 (Digital Sound Enhancement Engine).

In addition to this, there is support for Speak-to-Chat technology that allows you to detect when you speak, stops canceling the sound, and allows the passage of ambient sound so that you can have a conversation without taking them off.

In terms of noise cancellation, these headphones inherit Adaptive Sound Control functionality, which analyzes where you are and what you're doing, and varies the noise cancellation mode.

Another feature is the use sensor that allows you to pause or start playing your music as you take them off or put them on. And something that I find very useful is also the proximity sensor that detects when you're wearing one or both.

Price and availability of the new sony top headphones

The Sony WF-1000XM4 headphones will be available in two models: black with copper accents and silver with gold accents.

They will have an approximate price of 280 euros and can be purchased this June. Yes, we talk about the highest range and struggle with top models in the price range of 250 euros onwards.

We are testing them right now for within a few days and some cycles of load and daily use to be able to offer you our complete analysis.

We can tell you that they sound very good and that Sony has done a great job of optimizing to achieve this level of sound with a driver of only 6 mm. It's going to be true that size isn't everything.
