Portable plug-in subwoofer sound card reader with 800mAh battery, 2.1 track sound, 32GB storage, and 10m wireless range for desktop PC use, available in five colours including black and blue
Portable USB Sound Card Reader with 2.1 Track Audio, 800mAh Battery, and 32GB Media Support

This compact multifunction device addresses several common desktop computing needs in one portable unit. It serves as a plug-and-play USB sound card for computers lacking adequate audio output, while simultaneously functioning as a wireless Bluetooth 4.1 speaker and multi-format media card reader. The integration of these three functions – audio enhancement, wireless playback, and physical media access – makes it particularly useful for desktop PCs without built-in card slots or quality audio outputs. With a built-in 800mAh lithium battery providing up to 2 hours of operation, the device maintains portability despite its multiple capabilities, allowing it to function independently from continuous power connection when needed.
Features and Construction

The device combines several audio and media functions in a single metal-shelled unit designed for straightforward desktop use. Its construction centres around practical integration rather than specialised single-purpose performance, making it suitable for users seeking basic enhancement of their computer audio setup without complex installation or multiple separate devices.
Material and Build
The metal shell provides durable housing for the electronic components while offering some degree of heat dissipation for the internal circuitry. This construction choice supports the device's portable nature, as metal typically offers better protection against everyday bumps and impacts compared to plastic alternatives. The physical interface includes buttons for operation mode selection and speaker adjustment, maintaining simple control without requiring software configuration or complex setup procedures. The metal exterior also contributes to the device's aesthetic presence on a desktop, with colour options including black, blue, golden, red, and silver to match different workspace preferences.
Size and Practical Fit
As a portable plug-in device, its design prioritises desktop convenience rather than permanent installation. The 10-metre effective Bluetooth distance allows the speaker component to be placed optimally within a typical room while maintaining wireless connection to the host computer. This range supports flexible audio positioning for better sound distribution compared to directly attached speakers. The device's multi-function approach reduces cable clutter and device count on the desktop, since it consolidates what would typically require separate sound card, external speaker, and card reader units. The plug-and-play USB interface ensures compatibility with standard desktop PCs without requiring dedicated sound card slots or internal expansion.
Uses and Placement

This product serves both basic enhancement of desktop audio capabilities and convenient media access for various computing scenarios. Its combination of features makes it particularly relevant for users working with multiple audio sources or physical media formats who prefer a consolidated solution rather than multiple peripheral devices.
Event or Professional Use
For presentation environments or small-scale audio playback scenarios, the 2.1 track sound with subwoofer output provides adequate audio enhancement beyond basic computer speakers. The signal-to-noise ratio of ≥75dB helps maintain clear audio reproduction during playback of presentation media or background music. The card reader functionality supporting 32GB storage allows direct access to presentation files or audio content from various memory card formats without requiring separate adapters. The Bluetooth 4.1 wireless capability enables the speaker to be positioned optimally within a small meeting room or presentation space while maintaining connection to the host computer up to 10 metres away.
Everyday Home Use
For general desktop computing, the device enhances built-in computer audio with its dedicated sound card circuitry and separate speaker driver. The frequency response range from 100Hz to 20kHz covers the essential spectrum for music, video, and gaming audio at moderate volume levels. Media playback from USB flash drives or inserted memory cards provides convenient access to personal music collections or downloaded content without occupying the computer's primary storage. The 2-hour battery runtime supports temporary portable use, such as moving the speaker to another part of the room while maintaining audio playback from the computer via Bluetooth connection.
Benefits and Buying Value

The primary value of this product lies in its functional consolidation and straightforward enhancement of standard desktop audio capabilities. It addresses specific limitations of many desktop setups while maintaining simplicity of operation through button controls and plug-and-play connectivity.
Reuse and Low Maintenance
The device's multi-function design reduces the need for multiple separate peripherals, which in turn decreases cable management requirements and potential points of failure. The metal shell construction typically offers longer service life than plastic equivalents for desktop use where occasional movement or adjustment might occur. Simple maintenance involves occasional charging of the 800mAh lithium battery to maintain the 2-hour portable runtime, with no complex software updates or driver installations required for basic functionality. The card reader and USB flash drive support extends the usefulness of existing physical media collections without requiring computer-internal card slots or separate adapters.
Why Choose This Product
This device offers a practical solution for users seeking to enhance desktop audio while adding convenient media access capabilities. The combination of USB sound card, Bluetooth speaker, and card reader addresses several common peripheral needs in one compact unit. The 2.1 track audio with subwoofer output provides noticeable improvement over basic computer speakers, while the 10-metre Bluetooth range allows flexible speaker placement. For desktop setups lacking built-in card readers or quality audio outputs, this product delivers these functions without requiring internal hardware installation or multiple separate devices. The available colour options – black, blue, golden, red, and silver – offer some aesthetic choice to match different workspace preferences.
