Sony is one of the world's largest manufacturers of electronic products, and its headphones have a large number of products, from entry-level to audiophile-level, covering all aspects, not only excellent appearance, but also excellent performance. In addition, Sony is also the most concerned headphone brand among consumers, ranking first in the U.S. market in terms of product ownership.
 
Although there are a large number of products, Sony is rarely seen in the selection of various media, and its award-winning products are concentrated in a few models. Among them, the WF-SP700N is Sony's sports headphones that have received relatively many recognitions, and well-known media including CNET and bestproducts have praised it.
 
WF-SP700N is a split Bluetooth headset, the advantage is that it has added a noise cancellation function, which can be regarded as a sports version of WF-1000X, but its noise reduction ability is relatively average. At the same time, the WF-SP700N also has an ambient sound mode, which can avoid excessive sound insulation and reduce safety. In addition, it is fixed with shark fins, the weight of the unilateral earbuds is 7.6g, it supports NFC, and the battery life of 3 hours is short, but fortunately, it supports the fast charging function of charging for 15 minutes and listening to songs for 70 minutes, but the waterproof ability of IPX4 is really average. WF-SP700N supports AAC Bluetooth coding, the driver unit is 6mm, and the equalizer can be adjusted in the mobile phone APP.
 
Sony's new WF-SP900 is an evolution of the WF-SP700N. Compared to the latter, the biggest change is that the protection rating has been upgraded to IP65/8, which can be used in both fresh and sea water (with swimmer earplugs); The built-in 4GB storage space also makes the WF-SP900 more uninhibited. But it does not support fast charging, and other aspects such as appearance are the same as WF-SP700N, supporting noise cancellation and ambient sound mode, priced at 1999 yuan. Since the WF-SP900 was just launched in September 2018, it has not yet been evaluated by relevant media. And if you don't like split headphones, and need noise cancellation function, then WI-SP600N is the first choice, which is equivalent to a line between the two headphones of WF-SP700N, the appearance and performance are the same as the latter, the battery life is increased to 6 hours, and the price is 1199 yuan.
 
Consumers who pay special attention to the sound quality of headphones can also choose Sony's MDR-XB80BS, which is supported by LDAC, AAC and aptX, which is very rare in sports headphones. LDAC is an upgrade of Sony's Bluetooth-based compression transmission, which has higher specifications than AAC and aptX, and achieves the restoration of Hi-Res level listening effect, and there is no problem with Bluetooth listening losslessly. Audiologically, the MDR-XB80BS's low frequencies are thick but not loose, and the mid and high frequencies provide enough lines for vocals and instruments to stand out from the low frequencies, and the spatial sense of sound is not large. In other aspects, the MDR-XB80BS adopts an earhook design and is IPX5 waterproof, but it weighs 27g and does not have a strong battery life of 7 hours.
 
It should be noted that XB is Sony's bass series, and there are three sports headphones under this series: MDR-XB80BS, MDR-XB50BS and MDR-XB510AS. Overall, the MDR-XB80BS has the most balanced performance; The MDR-XB50BS is lighter at 22g and has a battery life of 8.5 hours, but it is only IPX4 waterproof and only supports AAC Bluetooth encoding. The MDR-XB510AS is a wired headset.
 
Last but not least, the WS series is defined by Sony as a sports waterproof player with IP65/8 protection and can be used in water. And it supports the fast charging function of charging for 3 minutes and listening to songs for 1 hour, and the ambient sound mode can be turned on, and the wearing mode is all over-the-head type. In addition, the WS6 series can play music from its built-in storage space and can also be connected to a mobile phone as a Bluetooth headset, while the WS4 series can only play music from its built-in storage space.
 
NW-WS625 is the flagship product of the WS series, the biggest feature is the addition of a ring remote control, which can be put on the finger for blind pressing, no need to touch the earphones frequently, and has 16GB storage space. The WS6 series only has two products, NW-WS625 (1299 yuan) and NW-WS623 (899 yuan), the latter does not have a ring remote control and has a storage space of 4GB. Otherwise, both products are the same, supporting AAC Bluetooth encoding, and the battery life is between 4 and 12 hours depending on the form of music playback. The WS4 series has NW-WS414 (669 yuan) and NW-WS413 (559 yuan) two products, the difference between the two is only in the storage space, the former is 8GB, the latter is 4GB, and the battery life is between 7 and 12 hours.
