The TWS noise reduction earphone market is now competing with each other, as the strong entry of Apple's AirPods Pro and the influx of mobile phone manufacturers have led to a sharp increase in pressure from the traditional mighty Sony and BOSE.

February 26 news, the United States FCC filing page appeared the figure of Sony WF-1000XM5, that is, the fourth generation noise reduction beans.

Slightly unfortunately, FCC released limited specification information, including extended touch control, upgrade support for Bluetooth 5.3 and LE audio, support for Qualcomm aptX lossless transmission technology, and so on.

Of course, from the analysis of the product itself, noise reduction chip / algorithm, drive unit / sound quality training, battery life and other core functions are also expected to be improved to varying degrees.

At present, the domestic price of the cash XM4 is 1199 yuan. XM5 is expected to compete head-on with Apple's AirPods Pro 2 and Bose QuietComfort Earbuds II when it goes public in June and July this year.
