True Wireless Stereo (TWS) headphones enable you to listen and communicate freely without being restricted by cables or wires, and TWS headphones with active noise cancellation (ANC) make it possible to immerse yourself in a world of sound. Huawei launched the first-ever headphones featuring intelligent dynamic noise reduction technology in 2020, the HUAWEI FreeBuds Pro, advancing TWS technology to new heights.
Recently, Huawei opened up the anechoic chamber, which is free from echo, in its audio lab to outside observers, providing an in-depth look at the R&D that goes into Huawei’s noise reduction technology for TWS headphones. The anechoic chamber is used for collecting sound data in acoustic tests. It minimizes internal sound reflection, external noise, and provides a simulation environment for testing and verifying sound parameter curves.
