Features and Construction

The speaker's construction centres on its practical connectivity options and portable power system. The compact design prioritises functionality within limited space, making it suitable for both stationary and mobile audio applications.
Material and Build
Power is supplied by a built-in lithium battery system, which stores energy for cord-free operation. The battery can be recharged using the USB power supply mode, providing a convenient charging method compatible with standard USB ports on computers, power banks, or wall adapters. The external finish is available in either black or white colour options, offering choice in aesthetic presentation.
Size and Practical Fit
With dimensions of 90x73x73mm, the speaker maintains a compact footprint that fits easily on desks, shelves, or in bags for transport. This size makes it suitable for personal audio in smaller spaces where larger speakers might be impractical. The square proportions provide stability during use while minimising the surface area required for placement.
Uses and Placement

The speaker's combination of wireless connectivity and compact design supports both casual and practical audio applications. Its features address scenarios where simplicity and flexibility are priorities over complex audio setups.
Event or Professional Use
The card reader function allows direct audio playback from memory cards without requiring a Bluetooth connection to another device. This can be useful for presentations, background music in retail settings, or situations where you need reliable audio without depending on a phone or computer connection. The built-in lithium battery ensures operation continues even when power outlets are inaccessible.
Everyday Home Use
For general home use, the wireless Bluetooth connectivity pairs easily with phones, tablets, or computers for streaming music, podcasts, or audio from videos. The compact size makes it suitable for bedrooms, home offices, or kitchen counters where space is limited. The black or white colour options allow matching with different room décors.
