Bluetooth headset can be said to have been widely used, and it can be seen in both office and life. I'm afraid the story is inconsistent. Technically, Bluetooth headsets are updated faster, and new products are introduced every year. From the marketing point of view, in order to compete for more market share, various brands will also launch corresponding new products, which seem to be updated faster. However, from the actual use, the basic functions of the Bluetooth headset have not changed much, but the headset shape, supporting software and sound effects are constantly optimized and upgraded. To sum up, whether the Bluetooth headset is updated quickly needs specific analysis.
