The concept of TWS true wireless earphones has begun to germinate as early as 2005. From the earliest products that only support call ears, after so many years of development, wireless headsets have derived a lot of categories, such as sports Bluetooth headsets, call headsets Hanging wireless headphones and more.

Through methods such as 2.4G radio frequency, a true wireless connection between the left and right of the two stereo headsets is realized, and the solid wire is no longer connected in the middle. Therefore, the TWS solution requires very high radio frequency signal technology.
