Why is IT 168 digital channel also called See Walkman? In fact, it is because I feel that it is difficult for Sony's previous generation machines to find the fashion soul that originally belonged to Sony. Walkman brings you too many good memories. Can Sony, which has been troubled for a long time, give new vitality to its products? If it doesn't die in silence, it will break out in silence, and now, Suojia's eye-catching products are finally on the market. NWZ-A 845 million stars, the new flagship of A series, has attracted much attention. Slim and fashionable appearance, charming texture, brand-new S-master technology, products that countless walkman fans have been waiting for for a long time.
Packaging and accessories:
The packaging of A845 is similar to that of a machine, with a long strip and black as the main tone. Transparent packaging can directly see the whole picture of 845. The packaging style is relatively simple, which saves a lot of materials and makes people pay more attention to the protagonist 845, but it is also very three-dimensional. Unpacking is similar to many machines. There are two floors, one is the machine and the other is the accessories. Accessories are relatively simple. In addition to a lot of pieces of paper from the Bank of China, there are also special USB data cables (with a large circle of common TDK magnetic rings), large, medium and small silicone ear muffs with earplugs, and Walkman has been wasting plastic player racks, plug converters and audio input cables used in airplanes. The original earplug of A845 is NC033, which adopts NC noise reduction technology.

Presided over the work and details:
A845 comes in three colors, black, champagne gold and purple, but it's a pity that the Bank of China only has black at present. In fact, the other two colors are more eye-catching. Black is a bit too tired in recent years, and many people choose to go another day.
Take A845 out of the plastic box. Wow, it's really thin. The thickness of 7.2mm will be very slim even without any trimming design, which is also a highlight of A845. The long fuselage has parallelogram sides, which is not monotonous, but also reminiscent of the design similar to MOTO E8. The whole fuselage is made of metal matte material, which is not easy to leave fingerprints, moderate in weight and feels good. The screen is covered with a transparent mirror material similar to a CD, which has high flatness and strong reflection, so it is no problem to be a mirror. There is a film above the screen, which may protect the mirror from being scratched. A 2.8-inch OLED organic light-emitting screen on the front of the machine occupies most of the area, and Sony LOGO is clearly visible above the screen.
The area below 1/3 is the main operation area of A845, which keeps the key arrangement before Walkman, including navigation key+play key+exit and set key. The ring, even the middle ring, looks a bit like Mickey. To tell the truth, it's a bit embarrassing to see the shell like A845 for the first time, but the silver metal buttons adorn the black host for a long time, which has a special mood. There is a golden Walkman Logo in the lower right corner of the outermost circle of silver, which also increases the metallic texture of the host. The buttons are basically concentrated at the bottom of the machine, and the screen itself occupies the upper part of the fuselage. When operating with one hand, the machine feels unstable, and the buttons feel similar to Sony's previous buttons, but they feel good and not too hard. There are volume increase and decrease keys and lock keys on the right side of the fuselage. Among them, the play key and the volume+key are both set with blind spots, which are used as identification keys for blind operation, so that people will not be unable to find the north in actual use. There are three oblique damping protrusions above the mechanical locking key, which are just consistent with the oblique direction of the fuselage parallelogram and form an echo. It reflects the consideration and intention of Sony product design details.
Under a big golden WalkmanLogo on the back of the machine, CCC certification mark, manufacturing model and other information are scattered randomly, and of course there is a reset hole. The left side of the lowest part of the fuselage is a 3.5mm standard earplug hole. The NC in this area has no previous small protrusions, and it is all integrated in the plug. So, the plug looks normal. It is worth noting that the ear hole of A845 has two layers, so it can move slightly. Below the machine is the data cable interface, which is directly exposed. On the far right is the fixing buckle of the hand rope, which hides a small screw. Plus two screws on the back of the fuselage, you can see three screws on the fuselage. The overall workmanship of A845 is acceptable, which belongs to the upper-middle level. Personally, I think it is better than the previous generation A8 1X and S61X.
More details
GUI and operation function FM
Tear off the sticker showing the organic light-emitting diodes at the top of the screen and you can get a glimpse of the whole screen. Boot up quickly, and the same familiar Jiugongge interface is displayed in front of you. As I said just now, the operation buttons of the 845 have kept the way of the previous generation, which is very convenient and easy to use. The host function is not complicated, but it is also a common function of foreign brands, such as music playing, video playing, radio, picture browsing and so on. The response speed of the machine is as fast as ever, and the settings haven't changed much. China Bank supports multiple system languages. Added voice learning function, this function is purely for parents, right? Moreover, the battery protection function is added, as if it means to stop charging when charging reaches 90%? But this function is really a bit strange. Generally speaking, the GUI setting of A845 is still relatively fine, with slight dynamic effect, and the main interface icon has a faint light, which is relatively simple as a whole, and it also supports the function of custom wallpaper, which looks very eye-catching.
The FM function interface is good, simple and clear, the function is still the same, the measured radio effect is normal, and no radio station can be found here.

Screen performance
The A845 uses an organic light-emitting diode (OLED) like XK. The screen display effect can basically be described as stunning. Although the precision of 2.8-inch resolution 400X240 is not high, the display effect is still delicate and the color saturation is very high, so the color will feel gorgeous by comparison, the screen brightness will not be too high, and it can be adjusted by 5 levels. The screen basically does not exist, but the angle is a problem. It's really like putting a picture on a distant screen. This screen should also be regarded as one of the highlights of the machine, making it easier for people to feel the exquisiteness of A845.
The picture browsing function of A845 supports the generation of thumbnails, but the thumbnail size cannot be adjusted. In practical application, many 800X480 JPG images are copied, and the image analysis speed is a little behind the rhythm when switching images. Thanks to the excellent screen, the picture browsing performance is excellent. It is a brand-new experience to enjoy many beautiful pictures while listening to songs.
Contrastive display
By the way, here are some screen contrast pictures, please upload them for reference. The screen color saturation of A845 is very high.
Music playing
This time, A845 switched to a music playing interface similar to XK, which changed the style that the album cover was very small in the past. The album cover is greatly stuck in the middle of the screen, the song information is displayed above the album cover, and the playback progress bar is below. You can still choose songs conveniently by artists and albums, but I usually use folder items. In the music playback interface, pressing the navigation key up or down can directly preview the album cover, and long pressing will have a dynamic effect similar to Piclens. Press the option setting key to bring up the music option, and you can directly adjust the sound effect and cycle mode. And you can press and hold the Return key to directly return to the main interface for other operations.

Sound performance, numerical control noise reduction:
As the flagship of Walkman A series, the sound performance of A845 is the second digital player product with S-master technology. (Official introduction: S-Master is widely used in Sony's home theater series products, which can process sound signals, eliminate analog signal errors and distortions, and reproduce exciting original sound effects. At the same time, A845 also supports all audio technologies of Sony MP3 digital players, such as ClearBass ClearStereo Dess VPT noise cancellation, which was common in the past. It can be seen that Sony is committed to the music restoration of this product, which gives music lovers and walkman lovers more choices at the same time as the historical peak XK. Of course, this is also one of the reasons why people pay so much attention to the A845, which combines thousands of stars and splendors. But I personally don't burn equipment, and I'm not a fan of Sony. I believe everyone knows that the sound performance is more personal experience, and different plugs can also produce different listening feelings. Here I just say my true feelings. As for music, I won't talk about the audition album here, and there is no plug in my hand now. And I suddenly found that the music files in my notebook add up to only a little more than 4 G. Originally, I didn't know how to listen to songs with this notebook. After copying music files to A845 with a capacity of 16G, there are still many movies, animations and OST. In fact, I personally listen to miscellaneous music, and prefer light music and instrumental accompaniment. I just listen in a mixed environment, in the dead of night, outdoors in the warm winter sun. My own digital products have a high turnover rate, but I can get straight to the point that 845 is indeed an excellent performance of the sound I have heard in MP3, both in sound quality and sense of hearing, but also in details. If you have been listening to Sony's machine before, you can hear a friendly and familiar voice in the first ear of 845. Feeling maintains the style positioning of the previous generation of machines, with small sound field, solid sound, balanced density, sweet sound, full sense of encirclement, easy to fascinate people and prominent intermediate frequency. The pop music style is more colorful and rhythmic. Compared with the previous 8 1X series, the A845 integrated with S-master music restoration technology is more calm when performing large-scale textures or complex musical instruments in sound stage, and some shelves that are in danger are more easily taken back. Of course, the equipment in hand at present may not be able to evaluate the performance of 845 analysis and hierarchy. But A845 can promote PX 100 in my hand very well. This was originally used by me to watch movies with my notebook. Compared with the sparse low frequency on the notebook, the low frequency of PX 100 on the 845 converges a lot, and CB also brings more flexibility and texture. Compared with the rough mine in the notebook, the sound is more delicate. I feel that the overall sound quality is much better than that of a notebook. Although the equipment limited the play of 845, it still moved me. A845 is really born for music. In addition, the low noise of the 845 is not obvious, but it can be felt by the original plug, but it belongs to a constant type and will not become a variation of the noise floor.
The original plug of A845 is NC033, which is supported by NC technology. It's rare to see your evaluation of it. I wonder if everyone bought all the plugs and threw them away? Let me talk about my personal feelings here. I think the sound performance of the original plug NC033 is a bit disappointing, and the overall workmanship is not bad. Like the machine, it is made in Malaysia, and the bright paint can also be well matched with 845, but the sound performance is not satisfactory. Personally, I feel that the sound is dull and chaotic, especially for sound stage, such as the new century symphony, which will be very inadequate, and I feel that there is a lack of transparency. I've been cooking for a long time and I haven't seen any improvement. Compared with Suojia's non-NC plug, NC has one more Mic module, so it also has a certain impact on wearing comfort. However, I am used to Sony's plug wearing comfort, which is far from MX760 and EX500. It is basically difficult to have surprising details. I always thought it was the NC version of the EX300, and my first ear was shocked. I'm a little anxious to go to Kyushu. Although the praise has improved slightly, I still feel that even compared with the previous generation 082, it is half a catty. NC033 bass also belongs to many types, with sufficient sense of quantity, moderate dive but lack of texture. After cooking for a while, the sound is a little less stuffy, but it still looks a little stiff. The middle and high frequency performance is not outstanding. Compared with EX500, the sound field of 033 is also very small, but the sound of 500 is extremely delicate and touching. 033 is more like a lout and looks rough and fearless. As a machine plug whose hearing is more important than sound reproduction, NC033 is not brilliant. In contrast, the PX 100 at hand is basically high-frequency, unappreciative and muddy, but vivid, breathable and full of vitality. Listening is much better than NC033. 033 is closer to the plug feeling of the innovative EP630 rambler H260, and it doesn't match Suojia machine. But such a plug, coupled with the NC noise reduction technology of Sony Niu X, makes it impossible for you not to love him.
Application of numerical control noise reduction;
The application of numerical control noise reduction technology (full name digital noise reduction) is still necessary. The noise reduction effect of turning on NC in noisy environment is obvious, especially when the bus covers all low-frequency engine sounds, which is obviously reduced after turning on, but the voice of the person next to it will be displayed at a very special frequency, which will still be vivid, but after all, it is not the most annoying roar on the subway bus and has little impact. Therefore, the noise reduction effect is not ideal for intermediate frequency and high frequency, but ideal for low frequency noise. After turning on the numerical control technology, the sound pressure will increase, but I didn't feel the obvious mixed sound as some friends said. In another case, I found that the shaking car on the bus will make abnormal noise in the plug, and noise reduction will produce new noise. I wonder if it's a BUG? Generally speaking, NC033 can't really show the infinite charm of 845. After all, Sony's own 500 700 wouldn't have to be sold if it was original. As a plug equipped with NC technology, it is acceptable to listen to pop and minority music. After all, it is enough to listen to the rhythm in a noisy environment, and there is no need to ask for too many details. There are also aircraft environment and office environment to choose from in the NC noise reduction technology selection panel. I feel that the roar on the plane is more harsh. I don't know what the noise reduction effect is, so I can't try it here.
video display
A845 supports AVC-encoded video, and tested several self-suppressed videos. The video is encoded by AVC BL, the sound is in AAC format, and it plays normally. Thanks to the excellent screen, the video performance of 845 is also good, but the screen resolution and size also make the video very nervous, so it is still possible to play MV. The machine can directly check the video information, coding method, file size and so on. The video supports fast forward, and the speed is 1X to 3X. A845 video also has a video browsing function similar to PSP, which is very fast and it is more convenient to find specific video content. The video that has just been put in and has not been played will be marked with a new one on the video icon. Video preview also needs a picture, which cannot be generated automatically. Why not learn Sony Ericsson's mobile phone? Of course, for those who use software to transform themselves, there is no need to do that.
Yeah, that's right. Recently appeared frequently "Avatar" trailer
Alas, pay attention to the content on the screen.
Evaluation summary
Accessory function, speed test and durability:
Sony also comes with its own software Content Transfer to transfer files, but I still like the feeling of freedom. Dragging files directly into A845, 16g, also makes the transmission of friends who listen to small format music like MP3 AAC as free as running in the wild. The transmission speed of 845 is satisfactory. In the actual test, the transmission speed of fragmentary pictures and music files can reach 5M/S, and the transmission speed of large files is faster, which greatly saves the copying time. For A845' s slim figure of 7.2mm, the endurance of 10+ is not bad. If it weren't for the train party, it would be enough. After all, this machine does not aim at battery life, and high-level music performance is believed to shorten battery life.
Summary: surprisingly slim, inspired and daydreaming design, textured metal shell, outstanding display effect, perfect system and exciting sound performance. As for more, I'd better experience it myself, otherwise my passion here is useless. In short, all this has brought me too many surprises, and I have to say that A845 is an eye-catching product.
Yes, this is Walkman, a little warm, a little touched, full of life and vitality. I believe A845, which is full of fashion, charming fragrance and even more intoxicating, will not let you down.
