Design of the Sony WH-1000XM4

The design remains virtually unchanged from the previous version. This is not a negative point, as the 1000XM3 has a refined, elegant and subtle appearance. The Sony WH-1000XM4 are over-ear headphones that look sober, and you can use them anywhere without attracting too much attention. They are made of durable plastic, and feature soft-touch padding. The construction quality is excellent, and they are very comfortable. You can use them for hours without them causing any discomfort.

They integrate a pair of physical buttons for power and Bluetooth synchronization, and an additional one that allows you to switch between the modes of the active noise cancellation technology. In addition, the outside of the cups function as a touch control panel that you can use to control playback, change songs and turn the volume up or down. They feature a 3.5mm auxiliary audio port, and a USB-C port for charging.

One of the best features offered by the new Sony WH-1000XM4 is the QN1 chip. This processor offers improved ANC technology by constantly sampling the ambient sound to adjust noise cancellation levels. It's a very smart technology that separates these headphones from the competition.

The Sony WH-1000XM4 are stylish, comfortable, offer the best noise cancellation on the market and a unique sound quality for wireless headphones. They are also portable: they can be folded inward, for easy transport in the carrying case included in the purchase package. Our only complaint is that they don't have water protection. They are perfect for everyday use and insulate you in any type of environment, but you cannot use them in the rain.

Best active noise cancellation

the WH-1000XM3 remains one of the best headsets on the market. The touch controls, noise cancellation and smart features stand out. The new Sony WH-1000XM4 inherits all the greatness of the previous version, and adds significant improvements that put it at the top end of the market. The most important upgrade is the new active noise cancellation.

Noise cancellation technology has improved considerably, and is rivaled only by the Bose QuietComfort 45 and Sennheiser Momentum Wireless. At first, the difference is not very noticeable, but after using them for a few hours you realize that they block mid-range noises considerably better. Once you start playing your favorite music, it completely isolates you from the outside world. The winds may cause some noise, but they offer the best ANC technology on the market.

Another unique feature of the Sony WH-1000XM4 is the ability to apply your preferred levels of noise cancellation or ambient mode according to where you are. The headphones play a tone when you arrive at any location, and adjust the noise cancellation level automatically. It needs GPS technology, so this function doesn't work on a subway, but you can create different settings and save them through the Sony Headpohones Connect app.

New functions of the Sony WH-1000XM4

As for noise cancellation, the Sony WH-1000XM4s use two microphones in each cup to isolate and analyze noise for you. The microphones, together with the superb QN1 processor, allow the headphones to analyze noise and adjust the ANC more than 700 times per second. The technology works flawlessly, and allows you to enjoy your music as clearly as possible.

In addition to unique noise-cancelling technology, the Sony WH-1000XM4 offers simple and efficient features to make your life easier.

Sony WH-1000XM4: Sound Quality

These Sony headphones use the same 40mm drivers as the previous version. They also offer the same quality in tonality and sound mixing. The audio feels warm and beautifully balanced. These are closed Over-Ear headphones, but the sound spatiality is surprising. Bass response is noticeable, but all frequencies are perceived as crisp, separated and with subtle detail.

We tested the Sony WH-1000XM4s by playing different formats through MP3 players and online streaming services. Performance was impeccable at all times, and they handle complex mixes with ease. The clarity and strength of the vocals stand out, but all the instruments are perceived as rich.

The rhythm and percussions are presented with enviable precision. The Sony WH-1000XM4 delivers dynamic, clear audio with great separation across all instruments. They are able to offer you the best sound quality in any kind of music genre.

They don't support the aptX HD codec, but this is because they work with Sony LDAC which offers really remarkable audio details for wireless transmission up to 990 kbps. They also feature the new DSEE Extreme technology, a process that restores detail in compressed formats to provide greater clarity. Even the lowest quality files sound great on the Sony WH-1000XM4s.

In addition, they integrate Sony 360 Reality Audio technology, a surround sound format that works amazingly well. For now, the digital library in this format is limited, but its performance is remarkable, and manages to create a very realistic surround effect.

Battery life

The battery of the Sony WH-1000XM4 has the same performance as the previous model. They offer an autonomy that reaches 30 hours with noise cancellation on, and up to 38 hours if you turn it off. At first, we were surprised that they did not improve battery performance, but it's understandable as they offer new features such as speech detection and new sensors. That said, it's a remarkable capability for a wireless headset with so many features. They outperform the Bose 700 and equal the B&W PX7 in this department.

The 30 hours are sufficient for weekend trips and international flights. The sensors that automatically pause or turn off the headphones when you take them off provide maximum autonomy. Furthermore, they charge very fast thanks to the USB-C port. Only 10 minutes of charging is enough to use them for more than five hours, and the entire charging process takes approximately three hours.
