What is a TWS earphone?

TWS is the abbreviation of True Wireless Stereo in English. TWS technology is also based on the development of Bluetooth chip technology.

TWS earphone has those characteristics

1. Truly wireless can achieve single and double ear wearing

The TWS Bluetooth earphone does not require a wired connection and gets rid of the shackles of traditional earphones. The two left and right earphones form a stereo system through Bluetooth, which improves listening, talking, and wearing. If you add professional acoustic pickup technology, intelligent noise reduction technology & AI algorithm noise reduction technology, you can achieve a perfect sound experience.

2. Intelligent noise reduction function

From the product point of view, the noise reduction function is an essential technology.

3. Semi-intelligence & intelligence

With the in-depth content in the APP, it immediately transforms into a smart interactive smart product.

Current drawbacks of TWS earphone

1. Battery life issue

Because of the size of a single ear, the battery capacity is difficult to increase. Although some manufacturers advertise that the battery life can reach 3-7 hours, according to a large number of measured data, the battery capacity of a single ear is between 25-60mAh. The longest use time is no more than 3 hours.

2. Noise reduction problems in complex environments

Noise reduction technology achieves the effect of noise reduction through methods such as network optimization + hardware support + software assistance.

3. The bottleneck of wireless transmission distance

Because the TWS earphone itself is a wireless call based on Bluetooth technology, according to the Bluetooth 4.2 protocol, its theoretical call range can reach 100 meters, and the new Bluetooth 5.0 theoretically can reach 300 meters, but in actual use, the complex environment, The circuit itself, radio frequency interference and many other issues limit its use distance; according to the measured data, the current mainstream use range in the market is 10 meters, and the farthest is only 12 meters. At this stage, according to domestic application scenarios, it is obvious Can not meet the user's experience needs.

4. The problem of sound quality and sound effect

Sound quality and sound effects, in addition to the need for good chips and solutions, good materials in the hardware are also needed. On the other hand, it also requires tuning in hardware + software (very professional). The cavity structure design of the earphone will be straightforward. The experience effect that affects the sound quality and sound effects.
