The Bose USB Link is a device designed to facilitate Bluetooth connectivity between Bose headphones and a computer, primarily for use in professional communication and audio applications. It allows users to connect their Bose Bluetooth-enabled headphones to a computer via a USB port, enabling features such as audio playback and microphone functionality for calls and meetings.
Function Description:
The primary function of the Bose USB Link is to act as a dedicated Bluetooth adapter for Bose headphones, ensuring a stable and optimized connection with a computer. It is designed to enhance the user experience by providing reliable audio and microphone performance, especially in scenarios involving communication platforms like Microsoft Teams. The USB Link supports multipoint connectivity, allowing compatible Bose headphones to connect to both the USB Link and a mobile device simultaneously. However, the Voice Assistant feature on headphones is not available when connected to the USB Link.
