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. Friends who have used TWS earphones know that it has main and secondary ears. You need to connect the main earphone first, and then connect the secondary earphone so that both ears can hear the sound. Do you know why?
This will start from the characteristics of TWS earphones. TWS is the abbreviation of True Wireless Stereo. TWS earphones are also true wireless stereo earphones, which consists of two independent earphones and a rechargeable storage box.
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.
That is equipped with master/slave switching technology, and the core is the chip solution. At present, there are many chip solutions provided by many chip manufacturers that support master/slave switching, with Airoha and Qualcomm as representatives.
UGREEN, which pursued to create high-quality products. The newly launched TWS Bluetooth earphone, UGREEN HiTune True Wireless Earbuds, uses the leading chips of these two manufacturers. The main features include master-slave switching, high-definition sound quality, dual-microphone noise reduction, Bluetooth 5.0, and so on, and it also designs with a Type-C charging port. I believe that Android and Apple users will have a wonderful audio experience of better sound quality, stable connection, low latency, and long battery life with True Wireless Earbuds.
