Features and Construction

The speaker's core features revolve around its wireless connectivity, power output, and battery. The construction details beyond the electronic specifications are not provided in the source text. The following sections outline what is known about the material and build, and the size and practical fit.
Material and Build
The source text does not specify the housing material or construction materials. Only the electronic components are described: a built-in 400mAh lithium battery, a USB interface, and Bluetooth connectivity. The 2.1 channel design suggests separate audio channels for a fuller sound, but no further build details are available. Without material information, no claims about durability or finish can be made.
Size and Practical Fit
No physical dimensions or weight are provided in the source text. The speaker is described as a "mini cannon" shape, implying a small form factor, but exact measurements are not given. Its practical fit depends on the user's needs; it is a compact device suitable for desktop or shelf placement. The absence of size data means no specific portability claims can be supported beyond the wireless feature.
Uses and Placement

This speaker can be used in various settings where wireless audio is desired. Its Bluetooth connection allows pairing with smartphones, tablets, or computers. The USB interface is for charging the built-in battery. The following sections describe potential event or professional use and everyday home use.
Event or Professional Use
With a 3W output and 2.1 channels, this speaker can serve as a personal audio device in small gatherings or presentations. The 60Hz-15KHz frequency range covers typical music and speech. The ≥75dB signal to noise ratio helps reduce background hiss. However, without a battery life rating or maximum volume, it is not positioned for large venues or professional sound reinforcement. It is best suited for intimate settings.
Everyday Home Use
At home, this speaker can be used for listening to music, podcasts, or audio from a connected device. The five colour options allow matching with different decors. The built-in 400mAh battery supports cordless playback, though runtime is not stated. The USB interface provides a standard charging method. It is a practical addition to a desk, shelf, or countertop where a small speaker is needed.

Reuse and Low Maintenance
The built-in lithium battery is rechargeable via USB, so the speaker can be used repeatedly without disposable batteries. No maintenance instructions are provided in the source text, but standard care for electronic devices applies: avoid moisture and extreme temperatures. The lack of specific care details means only general guidance can be given. Recharging is the primary upkeep required.
Why Choose This Product
