Speaking of earphones or walkmans, I believe that the first voice of every post-80s and post-90s generation is Sony. Yes, this legendary company is still active in the forefront of the consumer market after experiencing ups and downs. Although we have experienced difficult times, we will win if we persist in everything. Under the leadership of Ichifu Hirai, Sony has turned losses into profits and re emerged into the public consumer's vision. Among them, the most popular category is Sony Audio. Although the Walkman has been replaced by mobile phones, there is still a large market for earphones, speakers and players.
With the removal of 3.5mm headphone jack from smart phones of major brands, the market demand for Bluetooth headsets has surged in the past two years, and the major headphone brands have set foot in the Bluetooth headset market, which has become a must. The category of wireless earphones also includes multiple product forms such as full coverage headworn, neck hanging and true wireless. The true wireless earphones are the most convenient to carry and use. Sony has also recently launched a new product of true wireless sports earphones - WF-SP900, an IPX5/8 waterproof sports headset that can be worn not only for running but also for swimming.
Appearance and accessories
If the design style of the last two generations of products is classic, calm and commercial, the new generation of noise reducing beans is the representative of youth, vitality and sports. The bright color matching and dynamic design show that it is a product designed for young people and born for sports.
WF-SP900 provides a total of four colors, bright silver, light yellow, pink and black. This time, we got the light yellow. Unlike the flat storage of the previous generation, the SP900 uses a plug-in design similar to AirPods, which is also a popular design nowadays.
The main body and accessories are family photos. There are eight sets of earplug sleeves, four sets of normal earplugs, four sets of swimming earplugs, and three shark fins of different sizes. A nylon connecting cable is also attached. Users who are afraid of losing can put it on when they exercise to prevent loss. In addition to these, a USB-C charging cable is also attached.
The design language of the headset this time is relatively simple. It does not have a very complicated bending fit design like the SP700N. However, because of its smaller size, the actual wearing experience is not much different.
There is an ergonomic design of the ear on the inner side of the machine, which will not cause discomfort due to various projections when the ear is brought into the ear. This is also the basic design of earphones. The bottom of the headset is a charging contact. The left headset has more contacts than the right headset because it is a "host". When in use, pull out the left earphone, that is, Bluetooth connection with the mobile phone, and pull out the right earphone alone, it will not automatically connect.
As for the control mode, it is similar to the previous generation of products. It is still the touch+physical button mode, but there are some changes in the operation logic. The touch part is only responsible for the volume. Other operations such as connection, noise reduction switch, and sound mode are responsible for the physical button, which is easier to operate than the previous mode.
Wearing feeling
In fact, the wearing is basically similar to the previous generation product WF-SP700N, which comes with silicone shark fins of various sizes to meet the needs of users with different auricle sizes. Although some users are not accustomed to wearing shark fins, it is also the most real and effective means to prevent falling off in sports.
Earmuffs are special. WF-SP900 adds IPX5/8 waterproof grade to support the use of underwater swimming, so it also comes with two sets of six pairs of silicone earplugs. One set of earmuffs is for normal use, while the other one is waterproof earmuffs for swimming without holes. At first, it looks very special. After all, earmuffs without holes are not common.
Compared with other brands of sports earphones and pure wireless earphones, WF-SP900's biggest feature is that it supports IPX5/8 waterproof, which is also one of the few earphones that can really wear swimming at present, of which IPX5 is the level of water spray protection, IPX8 is a continuous immersion protection level. The SP900 equipped with swimming earplugs can not only withstand the water spray level, but also be immersed in the water 2 meters deep for about half an hour. It is a rare earplug design in the market that can be really worn when swimming. This design is quite rare.
In terms of wearing experience, it is not very different from normal earplugs. For users who are accustomed to wearing earphones, there should be no wearing problems, and the comfort is guaranteed.
The underwater mode has some special features. After all, it is a non perforated waterproof earplug. The sound transmission is obviously not so clear and smooth compared with ordinary earplugs, which is normal. Therefore, the volume needs to be properly increased when using underwater to ensure the music effect. However, there are not many kids who really can swim with earphones... Users who like swimming should pay attention to it.
experience
First, in terms of pairing, the basic logic of pairing is similar to that of other Sony true wireless headsets. The left ear headset is still the "host" connected to the mobile phone. All pairing operations are performed through the left headset, while the right headset is still the "auxiliary". This is quite different from AirPods, which does not distinguish between the main and auxiliary headsets, The difference in design thinking is also the main reason for the disconnection problem of the noise reduction bean right ear earphone.
In terms of operation, it is quite different from the previous one. The only way to increase and decrease the volume is to double click the headset this time. All other operations are transferred to the physical keys. The success rate of the operation is much higher. After all, the tapping operation is not very sensitive. However, everything has its advantages and disadvantages. After all operations are transferred to entity keys, the disadvantage is that the combination operation is very complex. Although the operation logic is similar to that before, for new users, it really needs to take some time to remember these complex operations.
In terms of the endurance, there are two cases. First, the Bluetooth mode. On the premise of full power+turning off the ambient sound, the endurance is about 2 hours. The Bluetooth mode basically maintains the same level as the previous generation of products, which is not good enough, but not bad enough. It performs normally.
The other is to play the music in the built-in storage. In this case, the Bluetooth connection does not need to be turned on, and the power consumption is reduced, so the endurance time is also improved. The endurance time is nearly doubled when the battery is fully charged. The total amount of music that the built-in 4GB storage can hold is basically enough for daily running. In order to maintain the endurance time, The author recommends using the built-in memory to play music. It is worth trying to double the endurance. However, it should be mentioned here that you need to download the supporting APP provided by Sony Music to import songs.
In terms of charging, similar to the previous generation, the earphone body is still charged through contacts. A single full charge takes about half an hour. When the charging box is fully charged, it can charge the earphone about 2.5 times. The charging box itself takes about three hours to charge. That is to say, in actual use, the total use time of the Bluetooth headset mode is about 4.5 hours, while the built-in memory playback mode is about 9 hours.
As for the connection that has attracted much attention, the connection mode between the two earphones has changed from Bluetooth connection to NFMI technology (Near Field Magnetic Induction, Near field magnetic induction). The connection stability is much better. In most scenes, there will be no connection problem. However, in narrow spaces, such as narrow corridors, there will be intermittent disconnection of the right ear at some angles. That is, there should be some space on both sides of the earphone, and it should not be too close to objects such as walls. This may be related to technology or engineering machine, There is no pressure to use it in most normal scenarios. In addition to improving the connection stability of the two earphones, the reason why the NFMI technology is replaced is that the connection problem after launching should be taken into account. After all, the characteristics of Bluetooth determine that its connection distance and stability will decline in solid and liquid media.
summary
With the gradual elimination of 3.5mm headphone jack for smart phones in the past two years, more and more mobile phone and audio equipment manufacturers have gradually shifted the focus of their product lines to Bluetooth headsets. Bluetooth headsets of various forms and functions have come one after another, and Sony Audio will certainly not miss this market. The most competitive market is clearly the pure wireless headset market. In addition to traditional headset manufacturers, major mobile phone manufacturers have also launched their own pure wireless headphones, which can be said to be very competitive. Sony has launched many well-known products in this segment. The WF-SP900 we experienced this time is Sony's latest work. However, compared with noise reducing beans, this one is more sports oriented, and waterproof and sports are its labels.
WF-SP900 In terms of design idea, the design idea of SP700N is basically continued. However, in order to improve the connection stability and take into account the data transmission requirements of underwater swimming, new connection technology is adopted, and the connection stability is improved compared with the previous generation of products. Although it is still not perfect in some scenarios, it is also a more thoughtful product in the current pure wireless sports headset.
On the whole, for users who like sports, the SP900 is a choice worth considering. On the one hand, after adding IPX5/8 waterproof, the adaptability of the sports scene has increased a lot, and you can even really wear it to swim. On the other hand, after adding the built-in storage, its working time in the independent working mode has increased a lot, and the change direction has increased the endurance time. Maybe this scheme is not perfect, but it is already a reasonable and effective solution for the current real wireless Bluetooth noise reduction headset.
