TWS is now all the rage as chip technologies play a key role

True wireless stereo (TWS) earbuds market has grown rapidly. According to Counterpoint Research, the global shipments of TWS earbuds will reach 230 million in 2020 with a compound annual growth rate (CAGR) of 80% from 2019 to 2022. With the introduction of Bluetooth 5.0, the communication speed, distance, and capacity of TWS earbuds have been greatly improved. Nowadays, in addition to the focus of appearance size and refinement, how to deal with the complex use scenarios and enhance the anti-interference capability, accelerating binaural synchronization, and integrating with the functions of voice biometric authentication, health detection, and wireless charging are the key indicators pursued by every leading manufacturer. 

Unlike traditional earphones, TWS removes the physical wire restraint and give earbuds the edge of multiple functions and better UI. How to ensure the noise-canceling effect, voice recognition rate, and the stability of binaural communication are the major challenges to the leading TWS earbuds brands. EDOM Technology is committed to providing the cutting edge solution to our partners with the latest processors, Bluetooth chips, power management chips, MEMS microphones, MEMS accelerometers, and bone conduction sensors.
