In January 2018, Sony released a new generation of WF all wireless series noise reduction earphones - WF-SP700N. Different from the previous wireless noise reduction series, this is the first all wireless sports noise reduction earphone in this series. Although WF-SP700N is a sports noise reduction headset, it has a strong sense of technology in its design. Sony seems to want to bring this "technology trend" into sports. WF-SP700N is also called "sports noise reducing bean" because it is similar to beans in shape.
appearance
After opening the package, you can see a WF-SP700N, charging box, earplug replacement, ear buckle replacement, data cable, and instructions. WF-SP700N adopts colorful color matching. There are four different color matching versions: black, white, pink and yellow. We Love to play computer games This time I got the pink version.
The charging storage box of WF-SP700N is made of plastic material, which is very light. The overall design is round and feels good. The color of the box corresponds to the color of WF-SP700N.
The charging storage box of WF-SP700N is square in design. The cover is opened by rotating, and the headset is still charged by contact. The charging storage box can fully charge the headset for up to two times.
The WF-1000X is called "noise reducing bean" because of its compact and round shape. This time, the WF-SP700N adopts a sporty design, but it is still a round bean design.
As a full wireless noise reduction earphone, there is a button on the left and right earphones of WF-SP700N, and the left ear is a function button to switch between ambient sound and noise reduction; The right ear is the play/pause function key;
As a sports noise reduction headset, the WF-SP700N has a waterproof level of IPX4, which can prevent splashing. At the same time, its earplug part is curved fitting silicone, which is more ear fitting and firm to wear.
Wear
In terms of wearing, the WF-SP700N does not have the "top heavy" feeling of noise reducing beans. Its internal components are evenly distributed. Although the weight is not too different, it is much more comfortable to wear. The earplug is still an in ear design of waterproof rubber plug. It is equipped with curved ear sticking silica gel, which is very firm to wear. The earphone will not fall out even when running violently or even standing upside down.
The design of WF-SP700N has a slightly curved shape, which is close to the curve of the ear side face. The Sony Logo is clearly printed in the center of the left and right headphones. After wearing, it has a full sense of technology.
experience
WF-SP700N does not support adaptive noise reduction. Users can adjust the ambient tone switch and noise reduction switch through the function keys on the left ear of WF-SP700N.
In terms of noise reduction, the noise reduction effect of WF-SP700N is worse than that of WF-1000X (neck worn). It can be understood as "blocking the ambient background sound". The noise reduction effect is not strong, but it is still available. Such noise reduction effect is also reasonable for WF-SP700N, which focuses on sports noise reduction.
In terms of sound quality, the author believes that the WF-SP700N is still a mid high frequency sound. The low frequency is not prominent, but it has a sense of speed. The sound trend is popular voice. Both male and female voices are OK. The mid frequency has a certain flavor. The high frequency is bright, overtones are few, and attenuation is weak.
In terms of connection stability, the connection of the WF-SP700N is very stable, and the disconnection has basically been cut off. Even in the complex signal environment, users only need to set the connection mode to "stability first" in the App to have a stable connection.
In terms of endurance, although the official announced that the WF-SP700N can be used for 3 hours with the noise reduction function turned on. However, in actual use, its endurance is basically about 2.5 hours, which may be related to the fact that the author adjusted the volume to more than 70%, and the official did not specify its volume when defining the 3-hour endurance. You can refer to the author's 2.5 hour range, which is a range of 70%. The charging storage box can provide two complete charges for the WF-SP700N, and the measured charging storage box can basically fill the WF-SP700N in 30 minutes.
summary
Although the WF-SP700N has no outstanding performance in terms of sound quality, it is understandable that it is a sports noise reduction headset after all. The advantage of WF-SP700N is that it not only maintains the design with a sense of science and technology, but also gives consideration to comfortable and stable wearing. It is also one of the few full wireless headphones equipped with noise reduction function. Although the WF-SP700N has no outstanding highlights (in fact, the design is also "bright"~), it is a practical sports noise reduction headset that covers all aspects. It has no obvious shortcomings, and its performance in all aspects is very balanced.
