Speaking of noise reduction headphones, the Sony WH-1000XM3 launched two years ago is still my first choice because of its powerful noise reduction effect and comfortable wearing, but people are always not satisfied with the status quo and always want to pursue new features. With new attributes, Sony has also launched the WH-1000XM4 under its own pace of continuous exploration. It uses the AI technology that has become popular in recent years to allow users to have better control over the sound and bring a more intuitive user experience.
Appearance part
The appearance of the Sony WH-1000XM4 is almost the same as the WH-1000XM3. It is the same as the previous generation. It is still available in black and platinum and silver, but with some improvements in details. The WH-1000XM4 adopts an integrated dumb body. Light design, improved the connection structure of the details, increased the contact area of the earmuffs, and concealed the sewing thread of the earmuffs. Although these improvements seem insignificant, it is this series of improvements that make the WH-1000XM4 headset have better texture, stronger workmanship, weaker ear pressure, and reduce the possibility of itching and allergies caused by sewing threads.
Button customization is what Sony has been doing in all its products in recent years, and this trend has also begun to spread to headphones. Sony WH-1000XM4 changed the original noise reduction button to a custom button, and the user can set the desired function through the “Headphone Connect” APP. Based on user habits, the custom button is still noise reduction control by default.
Functional experience
Intelligent, pick-free dialogue, this feature is also a major feature of Sony WH-1000XM4. The specific performance in practical applications is that if someone speaks to you while you are listening to music, the music will automatically stop playing, or you will speak to others. Triggering this function can effectively reduce the frequency of taking off the headset due to conversations; at the same time, the wearing induction function can automatically pause the music playback when the user takes off the headset, and automatically start playing when the user puts it back on. The benefits not only make the product smarter, but it also saves power to a certain extent and improves battery life, which greatly improves the overall user experience of the product.
Sound quality
This year’s Sony WH-1000XM4 ushered in two innovations in sound processing technology. The first is to make iterative improvements on the basis of the original DESS digital sound enhancement engine and upgrade to DESS Extreme; regarding this, the official Sony statement Through the Edge-AI technology jointly developed with Sony Music Entertainment, DSEE Extreme improves digital audio quality in real time, dynamically recognizes music styles and various elements, restores high-frequency signals lost during compression, and brings a richer and fuller listening experience. You can also enjoy Hi-res Wireless sound quality experience when connected. In short, it uses AI technology to dynamically identify the genre of music and supplement the audio signals lost in wireless data transmission, thereby outputting better sound quality.
Battery life
The official data of Sony WH-1000XM4 is the same as that of WH-1000XM3. It can be played for about 30 hours when noise reduction is turned on, and about 38 hours when noise reduction is turned off. Although there is no breakthrough in the data, don’t forget that this battery life is based on the Sony WH-1000XM4, which has been maintained on the basis of adding many new sensors and detections. Moreover, it can be used for about 5 hours of fast charging after 10 minutes of charging, and the battery life is not to worry about.
Summary
As a leader in the field of noise reduction headphones, Sony has always had a high level of noise reduction. Sony WH-1000XM4 also continues the excellent quality of WH-1000XM3, and has made improvements in many details, such as “Smart Pick-Free “Technology, combined with AI technology, is smarter and more “humanized” at the same time, making it feel better for users!
