With the rapid iteration of wireless audio technology, the transition between classic Bluetooth audio and the new-generation LE Audio technology has brought unprecedented opportunities and challenges to audio system upgrades across industries. How to preserve existing device assets while embracing the improvements in sound quality, مصرف برق, and multi-device connectivity brought by new technologies has become a core challenge for both enterprises and end users. Feasycom’s dual-mode Bluetooth audio transceiver USB Dongle solution delivers a one-stop answer for full-scenario wireless audio transmission with its innovative integrated architecture.

 

Industry Challenges

Ecosystem fragmentation, upgrade dilemma: Classic Bluetooth has built a mature device ecosystem based on HFP and A2DP protocols, but lacks capabilities in multi-device synchronization and low-power transmission. While LE Audio has achieved revolutionary breakthroughs in sound quality, مصرف برق, and connectivity, its market penetration remains limited. Enterprises are caught in the dilemma of “compatibility with old devices” در مقابل. “embracing new technologies” during upgrades.

 

Lack of Multi-Device Audio Sharing Capability: Traditional Bluetooth uses one-to-one connections, making it impossible to synchronously transmit high-quality audio from a single source to multiple devices. This fails to meet the needs of scenarios such as museum group tours, multi-lingual conference broadcasting, and family multi-person audio-visual sharing.

 

Inadequate Scenario Adaptability: Transmission distance requirements vary significantly across applications. Desktop offices require compact, portable short-range devices, while exhibition halls and large conference rooms need 100-meter coverage. A single product cannot accommodate diverse scenarios.

Solution

Feasycom’s dual-mode Bluetooth audio USB Dongle solution innovatively merges two independent audio transmission systems into a single unified platform. It delivers full compatibility with the existing classic Bluetooth device ecosystem and complete support for all LE Audio features, enabling seamless integration and smooth transition between legacy and new technologies.

  • USB Audio + A2DP/BIS/CIS Transmit Mode: Connect directly to a computer via USB. It can simultaneously broadcast BIS audio to multiple LE Audio devices, transmit CIS audio to designated devices, or stream A2DP music to classic Bluetooth device. One device satisfies the requirements of both legacy and new audio equipment.
  • A2DP Receive + BIS/CIS Transmit Mode: Only requires USB power supply. After devices such as mobile phones and tablets connect via A2DP, audio is automatically broadcast in BIS/CIS format. Connect-and-play with no complex configuration, enabling fast multi-device audio sharing.

The solution relies on two core LE Audio technologies to achieve comprehensive performance upgrades:

  • سیس (Connected Isochronous Stream): Supports two-way communication, precise left-right channel synchronization, and low-latency transmission. It ensures high-quality stereo music playback and clear voice calls, meeting scenarios with high reliability requirements.
