The audio market for wireless Bluetooth headsets is growing rapidly. Audio devices using Bluetooth (BT) connectivity are more ubiquitous than ever. People have gotten used to wireless audio systems, and the mobile phone industry is pushing towards a world without audio connectors and cables. The latest trend in wireless headsets and speakers is True Wireless Stereo systems (TWS), consisting of two independent units that are each charged in their own charging case. These headsets or speakers are typically connected through Bluetooth to an audio source while some contain additional memory to store music. TWS smart devices often contain integrated Active Noise Cancellation (ANC) to eliminate unwanted background noise from the received audio and at the same time minimize disturbances in the transmitted audio stream e.g., during voice calls.


1) What is True Wireless Stereo (TWS) technology?


True Wireless Stereo (TWS) uses Bluetooth signals instead of wires or cables to transfer sound. TWS differs from existing wireless accessories that do not physically connect to a media source but still rely on physical connections to ensure that both audio channels function together. As they are not connected to each other, the left- and right-side headphone of Bluetooth TWS can work independently. Technically, this means that a mobile phone is connected to the main headphone through Bluetooth wireless connection. Then the main headphone connects with the slave speaker through a Bluetooth wireless connection, thus achieving true wireless Bluetooth between both separate left and right channels of the Bluetooth headphones.
