1, positioning description Sony launched WF- 1000XM3 last year, which is already an excellent product. Today Sony has brought a new generation of WF-1000XM4, which has changed a lot compared with the previous generation. Let's see what upgrades have been made.
2. Appearance Description The outer packaging of Sony WF- 1000XM4 gave me a refreshing feeling. Because it is made of bamboo, sugarcane fiber and recycled paper, it can be recycled. It feels different from the outer packaging of 3C products that I dismantled before, and it has a natural intimacy.
3. Volume description: Sony has obviously reduced the size of battery compartment of WF- 1000XM4 this time. It seems that many users have complained that the XM3 battery compartment is too big to carry. Not only does it look much smaller, but the weight including headphones is almost twice as light. (The measured XM4 is 54.6g and XM3 is 92.4g)
4. Design changes Design changes also include earphone cavities. Sony chose to overturn the cavity design of WF- 1000XM4. The overall outline becomes round and full. This professionally customized in-ear monitor headphones must be designed to enhance the feeling when wearing headphones.
5. Before wearing it, users with oily ears reported that wearing XM3 would be unsafe. Sony realized this, so it chose to redesign the appearance of the cavity and cooperate with the matching sponge sound insulation sleeve to further strengthen the stability of wearing, even if it shook its head hard.
6. Get started quickly If you used to be an old user of Sony WF- 1000 series products, you can get started quickly with XM4. The control logic is still the familiar formula, and because of the increase of the touch panel area of XM4, you will feel much more practical when doing blind exercises. In addition, most of the functions are basically the same, which can be viewed in the official headset connection APP, so I won't repeat them.
7. Intelligent Pick-free Intelligent Pick-free function was first realized on Sony WH- 1000XM4 products, and now it has been transplanted to WF- 1000XM4. Simply put, this function is to judge whether the wearer speaks through microphone beamforming technology and bone conduction sensor. If so, stop the current audio task and enter the ambient sound mode, mainly to solve the problem of suddenly talking to people when wearing headphones.
I have to praise that the sensitivity and recognition of XM4 smart no-pick function exceed expectations. As soon as you speak, it can be recognized and started immediately, very quickly. But even so, I won't turn on this function in my daily use. There is a simple reason. If you are like me, you like to sing along or hum two songs when listening to songs, but this function becomes a burden. In addition to my situation, intelligent picking is still very practical in life. Of course, you can also change the pickup sensitivity and function residence time.
8. Noise Reduction Description The excellent noise reduction performance of XM3 is largely due to the built-in high-definition noise reduction processor QN1E. In the XM4 era, Sony once again broke through the limit and developed a new generation of integrated processor V 1, in order to make noise-reducing beans provide better noise reduction effect and lower power consumption.
In addition, XM4 also supports ambient sound adjustment of 1-20 gears, which can automatically adjust the corresponding noise reduction or ambient sound mode according to the current state of users. This humanization is also the excellence of Sony WF- 1000 series compared with other competing products.
As mentioned earlier, the power consumption of V 1 processor is lower than that of QN 1e processor. With the Bluetooth 5.2 transmission protocol of XM4, there is indeed a new breakthrough in battery life.
Prior to this, XM3 needed to turn off the noise reduction function to achieve a single 8-hour battery life, and now XM4 can achieve the same battery life even if noise reduction is turned on. In addition, this time XM4 also supports wireless charging QI function, and the fast charging efficiency has also been strengthened. Now it only takes 5 minutes to charge, and it can be used for one hour.
9. Finally, it is concluded that although the appearance is somewhat grandiose, Sony WF- 1000XM4 has made real progress in all aspects, which not only improves the noise reduction performance, but also strengthens the weight, wearing stability, sound quality optimization and endurance performance of headphones, not to mention the practicability of the newly added smart no-pick function, but at least the smart part has opened a clear gap with other manufacturers, which proves Sony's technological level.
Following WF- 1000XM3, Sony redefined the industry benchmark of in-ear noise canceling headphones by introducing a new generation of WF- 1000XM4. If you are looking for an all-round player-type noise-reducing earphone that integrates sound quality, noise reduction, wearing and intelligence, then Sony WF- 1000XM4 is the answer you are looking for.
