Description
The Esense D704 Bluetooth Mini Receiver is a professional-grade Class I wireless adapter engineered to eliminate the range limitations of standard Bluetooth dongles. By integrating the British CSR chipset and Bluetooth V4.0 + EDR specifications, it delivers a reliable 3 Mbps data transfer rate across distances up to 50 meters. This compact USB 2.0 device serves as a robust bridge for Windows-based systems, enabling seamless interaction with mobile devices, peripherals, and audio equipment without the constraints of short-range connectivity.
This product is for:
- Remote workers requiring consistent wireless headset connectivity across large home offices or multiple floors.
- Desktop PC users lacking built-in Bluetooth who need low-latency connections for wireless keyboards, mice, and game controllers.
- Audio enthusiasts utilizing A2DP-compatible headphones for high-quality wireless music streaming from a computer workstation.
- IT professionals seeking a stable, NCC-certified Bluetooth solution for legacy and modern Windows systems ranging from XP to Windows 10.
- Smart home hobbyists connecting multiple Bluetooth-enabled IoT devices to a central PC hub for data logging and control.

Operating the Esense D704 provides a significant upgrade over standard integrated Bluetooth modules, particularly in environments with high physical interference. The Class I radio technology ensures that signal dropouts are minimized when moving away from the workstation, while the CSR chipset maintains a high level of data integrity for sensitive peripherals. The inclusion of a dedicated LED indicator offers immediate visual feedback on the device's status, and the A2DP profile support ensures that wireless audio remains crisp and synchronized during media playback or VOIP calls.
Unlike standard Class II Bluetooth adapters that are typically limited to a 10-meter radius, the Esense D704 utilizes Class I specifications to quintuple the effective operating area. While many modern laptops include internal Bluetooth, those internal antennas are often shielded by the chassis, leading to poor signal penetration; this external USB solution provides a dedicated antenna path for superior range. Compared to newer Bluetooth 5.0 adapters, the D704 focuses on long-range stability for standard V4.0 peripherals, making it a specialized choice for users who prioritize distance and legacy Windows compatibility over the high-bandwidth, short-range focus of newer standards.
Q&A:
- Can I use the Esense D704 in a car stereo or with a standalone speaker? No, this adapter is designed specifically for PC use and requires a Windows operating system to function; it cannot be used directly in car USB ports or non-computer audio equipment.
- Does this adapter support wireless audio streaming? Yes, it supports the A2DP profile, allowing you to stream high-quality stereo audio from your computer to Bluetooth-enabled headphones or speakers.
- Is the 50-meter range guaranteed in all environments? The 50-meter range is the maximum specification for Class I devices in open spaces; actual range may vary based on walls, electronic interference, and the Bluetooth class of the connected device.
- Do I need to install drivers for Windows 10? The device is designed for plug-and-play convenience on most Windows systems, though specific CSR drivers may be required to access advanced software features or specific multi-language support.
- Can I connect multiple devices simultaneously? Yes, you can maintain concurrent connections with multiple Bluetooth peripherals, such as a mouse, keyboard, and smartphone, provided they utilize different Bluetooth profiles.
