About artifact, Sony NW-WS413 Walkman started evaluation
Intro: Trick walking out of the gate of the community, just to cross the road, to the cuff of a grandfather stopped, he reminded me on the road wearing headphones to listen to songs is not safe, "thank you, I can hear" . I have several pairs of sports headsets, but this artifact is the focus for me. It comes from Sony Dafa, a new type of sporty Walkman. Its model number is NW-WS413. In fact, it is a well-known fact that sports headphones are not well-selected. There are all kinds of pits everywhere. The wired ones seem to be embarrassing. Bluetooth has to have a mobile phone or a Walkman to wait on it. When noise is reduced, no ambient sound can be heard on the road. In addition to fear of danger, in addition to the wind, rain and sweat, it is necessary to take into account the waterproof function of the earphone (otherwise the bath can not bring, swim can not bring, rain can not bring, once wrong, no medicine can save) . Since the Sony NW-WS413, these troubles have been solved, because it combines the advantages of the public, taking into account the waterproof, cold, can monitor the environment, sound quality is not bad.
Sony NW-WS413 Walkman currently only supports local playback, without a Bluetooth module can not link with the phone, memory is only 4GB, a total of opal, yellow-green, gray black, light blue four-color optional. If you think the memory is too small, you can add one hundred dollars to buy the NW-WS414 to 8GB of memory. After the two, there is the new NWZ-WS615, which supports Bluetooth, NFC and other functions, so you can link with a smart phone, and comes standard with a ring-type remote control, unfortunately the price of NWZ-WS615 compared to the former Both are nearly doubled. The S in the WS two letter of the model should represent the meaning of SPORT.
Four pairs of conventional earphones (one of which is already installed on the machine), this is nothing to say, after all, headphones are standard on the market. Sony's pads are very comfortable to wear.
There are also four pairs of special earphone sets for swimming. The opening of the swimming earphone cover is covered with a thin film to prevent water ingress. The opening of the standard earphone cover is open.
In addition, a set of dedicated chargers is also standard. This is different from the NW-A25, NW-A27HN, NW-A25HN and other players. It takes a big step in the charging mode. It accepts the Micro USB interface adapter cable and the magnetic charging port. It has a lot of innovative points. , for the introduction of a waterproof chapter foreshadowed.
Sony NW-WS413 Walkman charging mode is a bit odd, first comes standard with a magnetic suction charging stand (seemingly suitable only for NW-WS413, NW-WS414, NWZ-WS615 equivalent type of product use), charging stand and standard With the combination of Micro USB short lines, together constitute a full set of NW-WS413 charger.
In any case, this kind of charging method is worthy of recognition and worthy of criticism. First of all, taking into account the waterproof requirements of the Sony NW-WS413 charging interface, the appearance of the NW-WS413 is also an important parameter for the design of the charger, the two need to be a collision, it will shape!
At present, this type of charging is still ideal. The charging stand can hold the metal contact with the body of the NW-WS413 and clamp it tightly. In the long run, this kind of charging method is not perfect, for example, it is easy to lose the charging seat (it is not universal before, and after the loss, the big trouble has only just begun).
The SONY logo is printed on the left ear, the Walkman logo is printed on the right ear, and a microphone is built into the left and right sides of the NW-WS413. Through it, you can listen to the ambient sound of the outside world. Even more rare is that this kind of monitoring is designed to be Controllable operation, just press the button in the process of movement, you can chat with others without having to take off the headphones, you can do while chatting while listening to music. After personally trying, I found that the effect of this button is still quite obvious. In the case of noisy environment and many people about running, it is recommended to open the monitor of environmental sound. Of course, this kind of monitoring is not a panacea. If the environment is complicated, it is recommended to take off the headset properly. Safety must not be ignored.
Is it Walkman also has a fast charge function (the recent write a small review of mobile phone crazy write, fast charge, hey), the official said the Sony NW-WS413 Walkman three minutes "fast charge", can play for about an hour of battery life, apparently for outdoor sports For one family, this is one of the selling points (charging treasure can handle several times).
Sony NW-WS413 Walkman's buttons and interfaces are done with waterproof (this is no surprise, after all, Sony's mobile phone sister favorite, because you can take it hot springs). NW-WS413's waterproof capacity is strong enough to be slightly abnormal, reaching the level of IP65/68 waterproof and dustproof (it can be soaked in water depth of two meters for half an hour).
Have to admit that the magnetic type charging interface is also going for the waterproof requirement (there may be wireless charging in the future, I'm very confident to affirm this! In addition, by the way, the so-called magnetic contact is The NW-WS413 was not magnetic, but it was just because it was seen on the tablet. I personally tested it. The contacts on the NW-WS413 are not magnetic. There are five gold-plated contacts. , waterproof performance is indeed blessed by them. Of course, when we copy songs, it is also achieved through the recharging USB cable.
We briefly introduce his button, the left side of the headset is arranged with volume addition and subtraction, MODE, environmental sound monitoring keys, the right layout has up and down song, pause/play and power switch (press and hold for about 3 seconds to start, the yellow light will light up ) Under normal use, the indicator light is yellow-green!
There are not many things that can be seen on the sound quality. Compared with the popular sports headphones on the market, Sony NW-WS413 Walkman's performance is basically in line with expectations, and it should be enough to satisfy the demand for the appreciation of the “about running†process. Although the figure is inconspicuous, there is still “energyâ€, like the sound of a tweeter floating in the campus. It is empty, open, hearty and reveals an ethereal, youthful atmosphere, bringing a pleasing state to the people. , Many people must be longing for and miss this time.
Summary: Sony NW-WS413 Walkman's introduction to the "about run" enthusiasts brought the gospel, wearing a very comfortable, but also both waterproof, cold, can monitor the ambient sound, good sound quality, with "fast charge" and so on, Will be "killed" opponents are not a piece of film. In addition, there are a number of products to choose from in the "Runabout" series. If you think that 4GB of memory is small, consider NW-WS414. If you want to take into account the smartphone's headset role, you can consider supporting Bluetooth, NFC, and NWZ with a ring remote control. -WS615, these three Walkman flesh hit your inner deer deer in minutes.
Suggestions: Maybe it's because the NW-WS413 in my hand is due to engineering prototype. The bit rate is too high or the lossless sound quality can't be played (it can only listen to 128kps or less). The official version should solve this small problem? An uncle in the park told me that if you also have a radio function, he will start with one. Do you not know whether Dafa can accept this uncle's suggestion? Should the charging stand also be more versatile?
