True Wireless Stereo (TWS) is the main solution for a new generation of true wireless stereo

True wireless stereo Bluetooth headset, the English special vocabulary is True Wireless Stereo, or TWS for short, is the latest innovation of Bluetooth headset / speaker technology, which can realize the wireless separation of Bluetooth left and right channels.

The core principle is to divide the speaker into a master speaker (TWS Master) and a slave speaker (TWS Slave):

The main speaker is a speaker that can receive A2DP protocol audio and AVRCP protocol streaming media control signals transmitted by smartphones, laptops and other devices (audio sources), and transmit audio to other TWS devices.

The slave speaker refers to a speaker that can receive A2DP protocol audio from the main speaker.

Comparing high-end TWS Bluetooth headsets, generally both speakers can be used as the main speaker.

The audio of the mainstream A2DP protocol of TWS technology can be transmitted from the main speaker to the speaker, so that the audio can be played synchronously in two separate speakers to achieve a stereo effect.

In addition to the whole machine, TWS's main solution provider, British chip manufacturer CSR, and NXP's NXP affiliated manufacturer integration have been acquired by Qualcomm, which is also a representative case of the industry's giants in the field of radio sound.

Compared with the ordinary Bluetooth headset, the wireless Bluetooth headset using TWS technology has obvious advantages in portability, high-definition sound quality, volume, intelligent level, and waterproof.
