For most people, the earphone is a necessary device that will be used every day. Many people are used to wearing it in commuting, running, working, or something else. Especially in the past two years, with the popularity of AirPods and the development of Bluetooth 5.0 technology, TWS earphones have become more and more popular.

Its best advantage is to get rid of the traditional physical cable. The Bluetooth earphone with the main and secondary ears, and relying on the coil to achieve the two Bluetooth signal transmission. When using it, you need to first turn on the Bluetooth on your smartphone. The phone will be paired with the main earphone (usually the right ear) first, and then the main earphone is transmitted to the secondary earphone to form a stereo system.

However, this way of connection brings some problems because the audio is transmitted from the main earphone, so the power consumption of the main earphones will be greater, which leads to the differences of battery life, charging time and service life between the main and secondary earphones. Besides, the transmission between the primary and secondary ears takes a certain amount of time, which affects the user experience more or less.
So, can TWS earphones be simplified to not distinguish between the main and secondary ears, and realize the independent connection of sound sources with the both earphone to achieve a better audio experience?

The answer is yes.
