True Wireless Stereo Technology - Facts and Background
Before we dig deep into TWS technology, let's first know more about why this wireless technology is related to headphones or earbuds. Bluetooth earphones, which are also called wireless headphones in general, work by radio waves instead of wires or cables to connect with cell phone, smartphone or computer. Compared with normal wireless headphones, true wireless headphones are designed without any wires, not even a wire connecting each in-ear headphone. True wireless headphones offer a truly tangle-free experience that allows people to feel free when they do something at some time.
What is TWS exactly?
It is the short form for True Wireless Stereo. The implementation of this technology is based on the development of chip technology. Technically, it means that the mobile phone is connected to the main headphone through Bluetooth wireless connection. Then the main headphone would connect with the slave speaker via a Bluetooth wireless mode connection, so as to achieve true wireless Bluetooth for two separate left and right channels of the Bluetooth headphones.
When no connection is made from the headphone, the main headphone returns to the monophonic sound quality. It is designed to provide customers with stable performance characteristics of high-end Bluetooth loud speaker programs. It needs 2 pieces of Bluetooth modules with TWS function to utilize TWS technology.
For TWS headphone, the left and right earphone are independent individuals. When two separate headphones near each other, they can match automatically and shift to double channel stereo. This technology could give you high quality sound.
On the other hand, true wireless headphones do not need any cables to charge. They could directly charge on its built-in high capacity lithium battery case. You would not worry about the signal problem when using TWS headphones, because there's a 10-meter range of signal. No matter what you do, driving or running, you can just leave your phone and go, which also means you could share music with others.
