On the morning of June 9, Sony officially released a new generation of noise-reducing beans-WF-1000XM4 true wireless noise-reducing Bluetooth headset in the domestic market, with a price of 1999 yuan, and has officially started pre-sale.
Sony's new generation of noise-reducing beans has changed a lot from the inside out, and any keywords such as new processor, LDAC support and Hi-Res wireless support are enough to make people look forward to. Headphones also integrate high-energy selling points such as wireless charging, professional sound quality, ultra-low delay, integrated control, clear call, waterproof and sweat-proof. To create a cool technology gameplay experience with comprehensive strength, so that more users can enjoy the convenience brought by real wireless noise canceling headphones.
So what is the performance of Sony WF- 1000XM4? Learn quickly through the actual hands-on experience of technology dogs.
Appearance analysis: the brand-new design is highly recognizable, and the "slimming" of the charging bin and headphones is very successful.
When the technology dog first saw the outer packaging of WF- 1000XM4, it became interested in it. The packaging materials not only use green recyclable raw materials such as bamboo, sugarcane and recycled paper, but also have obvious differences in packaging style.
Above: WF- 1000XM4 packing box is made of zero plastic and environmental protection "primary mixed material".
I have a special liking for "lossless unpacking", which can restore the packaging design of the product itself to the greatest extent and is more conducive to placement and storage. However, Sony's outer packaging "waist seal" adopts a disposable design, which means that when you open it and take out the headphones, it is impossible to restore 100%. The biggest advantage of this design is that it is a good guarantee for users, because you don't have to worry about the products you buy.
Sony WF- 1000XM4 comes with "simple" accessories, C-cable, two sets of extra earplugs and instructions. Take out the charging bin (storage bin) to play. The feeling of being small and light arises spontaneously. The size of the charging bin is reduced by 40% compared with the old one. The storage mode of the earphone host is also horizontally arranged, which maximizes the internal space of the charging bin and has good anti-drop and impact resistance. At the same time, it can protect the headphones very well, and it will not appear abrupt in your pocket.
In terms of appearance, Sony WF- 1000XM4 adopts a round and compact design and is decorated with golden circles. The radio microphone is placed inside, and the other microphone is located at the top of the earphone. The biggest area outside the earphone is the touch area, which is sensitive to touch, rich in functions and convenient to use with one hand. The quick reminder function is very useful. Just press your finger on the left touchpad to instantly reduce the music volume and amplify the ambient sound. So when you need to communicate with others for a short time, you don't need to take off your headphones. If you have used Sony's earphone products, the difficulty of getting started is almost zero.
In terms of details, the left and right Bluetooth headsets are embedded in the charging bin, and the headsets are marked with "R" and "L", which is convenient for users to identify and wear. Both the charging bin and the earphone have realized the "weight reduction" design. The weight of single-ear headphones has dropped from the previous 8.5 g to 7.3 g, and the comfort of wearing for a long time has also improved. The weight of the charging bin has also dropped from 77 g to 7 1g, which seems very small, but you can still feel subtle changes when you reach it.
In terms of battery life, the charging bin of Sony WF- 1000XM4 adopts the Type-C interface, which is compatible with the charging cables of mainstream Android phones and notebooks. When going out, I lost a wire, bid farewell to redundant wires, and increased support for Qi standard wireless charging. I have to praise it.
In terms of battery life, it can provide about 12 hours of battery life when noise reduction is turned off and 8 hours of battery life when noise reduction is turned on. The charging bin can provide two additional battery charges, which can provide a battery life of up to 36 hours when the noise is turned off and about 24 hours when the noise is turned on.
When the size and weight of the earphone and charging compartment are reduced, the battery life has not shrunk, but has been improved to some extent. For non-heavy users, this change is still very obvious. Taking the usage habits of technology dogs as a reference, a single charge can basically meet the needs of one week.
Technical analysis: brand-new V 1 processor, LDAC support, high-resolution wireless support.
Sony WF- 1000XM4 has been fully upgraded in hardware specifications. This new generation product adopts the newly developed integrated processor V 1. Sony officially said that V 1 absorbed and improved the noise reduction performance of QN 1e, which not only had stronger performance, but also lower power consumption, satisfying users' desire for a quiet environment.
Sony WF- 1000XM4 is equipped with a 6mm drive unit with a flexible diaphragm, which can increase the magnet volume by 20% and enhance the low-frequency performance. Because it has dual feedback microphones, it can capture more ambient sounds and perform better in noise reduction. Equipped with brand-new polyurethane earplugs, it is not only comfortable to wear, but also increases the contact surface between earplugs and ear canal, thus achieving better physical noise reduction effect, effectively isolating high-frequency noise and wearing more stably.
Speaking of the sound quality of wired headphones, we regard the "Hi-Res Audio" gold standard as one of the standards for high-frequency extension and detail restoration of headphones. In the field of Bluetooth headsets, the symbol to judge whether the sound quality is excellent is LDAC certification, and both of these certifications are from Sony.
The biggest feature of LDAC technology is to ensure the transmission speed of wireless audio, and it can also have enough information. In the practical sense of music listening, the sound is fuller.
Sony WF- 1000XM4 also brought a new improvement in call quality. Equipped with microphone beamforming technology, it can effectively improve the signal-to-noise ratio of the call and capture the sound accurately and efficiently even in noisy environment. At the same time, the bone conduction sensor is used, which is different from air pickup, but distinguishes speech from environmental sound by collecting the vibration of bones, further improving the call quality.
Above: Microphone beamforming (left) and bone conduction sensor (right) cooperate to improve pickup accuracy (schematic diagram).
Wear and use experience: the sound quality is in the first echelon of true wireless headphones.
In terms of sound quality, Sony WF- 1000XM4 supports LADC transmission, and has passed the high-resolution audio wireless authentication of "Hi-Res Audio" and "Hi-Res Audio Wireless". In fact, the density and intensity of sound are higher, the details of music are much richer, and the low frequency is deeper, which is not only a vague quantity, but also a stronger "texture". Users can feel the quality enjoyment brought by Hi-Res, and the sound quality is in the first echelon of true wireless headphones.
In terms of noise reduction, Sony WF- 1000XM4 integrated processor V 1 has improved the noise reduction performance compared with QN1E. At the same time, polyurethane foam earplugs can effectively isolate noise and enhance the passive noise reduction ability of headphones. Moreover, the dual feedback microphone can capture more ambient sounds and provide stable noise reduction effect in various environments.
In our daily life, we are often troubled by noise. No matter at home, in the office or on trains, planes and other vehicles, the noise emitted by vehicles has low frequencies, and these low frequencies are the best range for Sony WF- 1000XM4 to reduce noise.
On the plane, the technology dog wears Sony WF- 1000XM4 for practical experience. After putting on headphones and turning on noise reduction, it is obvious that the noise seems to have "disappeared". Sony WF- 1000XM4 If you often need to take transportation and want to have a quiet and comfortable journey, it is well worth having.
Sony WF- 1000XM4 supports 360 realistic audio at the same time. The' Earphone Connection App' of headphones can be used as the structural basis of sound optimization by taking photos and inputting the ear shape. The setup process only needs to follow the "wizard" step by step.
From the actual experience, the most intuitive feeling of 360 live sound effect is the enhancement of "sense of orientation", and the sound comes from all directions, just like being there. You can also enjoy the charm of immersive listening anytime and anywhere through 360 live tracks recommended on apps such as "Sony Selected Hi-Res Music".
Not only that, Sony WF- 1000XM4 has also added a "smart dialogue-free" function, which can identify whether you are talking or not, thus automatically adjusting the noise reduction level.
As shown in the above figure, the main interface of the APP terminal will display the power of the left and right headphones and the charging bin. We can also turn on Sony's signature adaptive sound control here. This function can switch different noise reduction modes by monitoring the user's actions and fixed position. Users can also customize settings and add fixed locations in the menu.
You can also set up advanced technologies such as noise reduction mode, intelligent pickup, equalizer, Bluetooth connection quality, 360 realistic audio and DSEE extreme digital sound enhancement engine.
We can set three modes: noise reduction, ambient sound and off. Ambient sound provides 20-speed adjustment. In the noise reduction mode, in addition to the standard mode, there is an automatic wind noise reduction function. This mode is recommended to be turned on in windy weather or riding.
The riding test of the technology dog is about 8 kilometers and takes about 33 minutes. Usually, wind noise will have a certain impact on general noise-reducing headphones. When Sony WF- 1000XM4 is used and the automatic wind noise reduction function is turned on, Sony WF- 1000XM4 will turn on certain ambient sound after detecting wind noise, and the phenomenon like "wheat blowing" will disappear immediately, and the actual feeling and effect will be displayed.
In the actual wearing experience, it is found that Sony WF- 1000XM4' s "intelligent conversation-free" function is very accurate, and it will only trigger when the wearer speaks. Even if someone is talking nearby, the headset will not trigger this mechanism. And you can also make personalized settings in the APP, the sensitivity of voice detection can be adjusted by yourself, and the start time of smart off-hook can be set according to your own habits. In addition to the powerful algorithm, this function should also have bone conduction sensors playing a role, and the actual effect is really good.
In the system, we can also set up a voice assistant, customize the touch function, change the default operation of headphones, and determine the best earplugs. Determining the function of earplugs allows users to choose the earplugs that are most suitable for them. It is achieved by testing the air tightness of earplugs, which is actually part of improving noise reduction performance.
Taking Chen Zhou's "Whale on an Island" as an example, the song adopts a brand-new arrangement method, skillfully arranging the distant and lonely whale songs into music. When Charlie's song and the whale's song are integrated, it is extremely ethereal and beautiful, telling a story of growing up in loneliness and love.
Zhou Chen sang his strong and brave feelings with rich emotional expressions. In the output of WF- 1000XM4, the vocal performance still maintains the first-class level, and the vocal is moist and clear, while continuing the style of WF- 1000XM3. Sony's best resolution and details are that WF is still outstanding-1000xm4, with stronger low-frequency dynamics and deeper dive. More importantly, with the addition of LDAC, WF- 1000XM4 can use higher standard music. When you turn on the noise reduction and hear this song again, you will instantly enter a very quiet world.
It should be noted that because the above listening sense is based on the feeling of pairing WF- 1000XM4 with Android phone, if you connect with Apple iPhone or devices that do not support LDAC, you can only choose the connection mode of AAC and SBC, and the sound quality performance will also be discounted.
In terms of game experience, the technology dog has experienced the game through the most popular mobile games "the glory of the king" and "Peace Elite", and the sound details can be reflected. People coming from a distance can clearly detect the footsteps of the enemy and the sound of opening the door in the building.
In terms of quality, Sony WF- 1000XM4 adopts a customized chipset. After repeated call tests, it is found that the call quality is clear and does not drift. Adopt "home" call noise reduction technology to further optimize noise recognition ability. Noise reduction microphone can identify environmental noise, eliminate noise in real time, and ensure the quality of answering and talking. From the actual experience, the call quality is very clear. When you make a phone call, noise reduction can filter the background noise, make your voice clear and audible, and bring a better call experience.
In terms of signal connection, wireless signal coverage is wider, and the connection is as stable as wired, which not only enhances the connection stability of binaural call, but also reduces the signal transmission delay, and the synchronization of listening and speaking effectively reduces the "time difference" of the call.
As long as you search for "Travel Notes of Technology Dogs" in "Du Niang", you can find out whether technology dogs are tired of hiking, climbing the Great Wall, driving long distances and other outdoor sports in the past six months. Therefore, the technology dog must be not afraid of rain erosion, not to mention sweat erosion, and professional protection from the inside out can give the so-called athletes the necessary protection. Sony WF- 100XM4 also supports IPX4 level.
Experience: If you can accept its price, it has almost no shortcomings.
Compact charging box, comfortable and stable wearing design, stable Bluetooth connection and true wireless LDAC provide better sound quality performance and better noise reduction effect. From the product strength and hardware level, Sony WF- 1000XM4 has reached a high degree of completion, and it also supports IPX4 sweat prevention and wireless charging.
At the same time, it is equipped with more intelligent adaptive voice control, smart and clear call, giving people an intelligent experience of "almost no manual control of headphones". Unfortunately, there is no NFC quick pairing and the same brand opening function. However, Sony has added more advanced functions such as bone conduction sensor and newly developed integrated processor V 1 to this headset, and has become an all-round player in its kind.
Then the final conclusion of the technology dog is simple. If you can accept its price, it has almost no shortcomings.
