This compact wireless speaker delivers versatile audio playback in a portable package designed for on-the-go use. It connects wirelessly via Bluetooth 5.0 to smartphones and tablets, while also offering direct playback from TF memory cards and external audio sources via a 3.5mm input. The integrated 1500mAh rechargeable battery supports extended listening sessions, providing up to eight hours of operation at 70% volume setting. With physical button controls, an included carrying belt, and multiple colour options, this speaker provides a practical audio solution for various environments.

Features and Construction

The speaker's design prioritises portability and straightforward operation. Its construction centres on a 5W audio system suitable for personal or small-group listening.

Material and Build

The speaker utilises an external magnetic speaker system rated at 4Ω5W, paired with an external magnetic horn of the same specification. This configuration is designed to deliver audio output with a stated separation of ≥90dB and a signal-to-noise ratio of ≥80dB. The unit's physical controls use button-based adjustment, providing tactile operation for power, volume, mode selection, and playback functions without requiring a smartphone app.

Size and Practical Fit

With dimensions of 81 millimetres in width, 81 millimetres in depth, and 116 millimetres in height, the speaker maintains a compact form factor. The inclusion of a portable belt attached to the unit's bare metal size allows for easy carrying by hand or attachment to bags. This design makes it suitable for use in various locations including outdoors, in vehicles, or around the home where space is limited.

Uses and Placement

The speaker's multiple input options and portable nature support use across different scenarios, from casual listening to more practical audio applications.

Event or Professional Use

For presentations or outdoor events where reliable audio is needed, the speaker's TF card support allows playback of pre-loaded MP3 files without requiring a separate Bluetooth device. The hands-free calling function via Bluetooth can facilitate conference calls or communication in settings where keeping hands free is beneficial. The FM radio function provides access to broadcast content without internet connectivity, which can be useful in areas with limited network coverage.

Everyday Home Use

Around the home, the speaker's wireless Bluetooth connectivity allows streaming from personal devices for background music in kitchens, studies, or bedrooms. The auxiliary 3.5mm input supports connection to devices without Bluetooth, such as older MP3 players or computers. Its portable design with the carrying belt means it can easily be moved between rooms or taken into the garden, while the 8-hour battery life reduces the need for frequent recharging during daily use.

Benefits and Buying Value

The speaker combines several audio source options with extended battery performance in a single portable unit, offering practical advantages for users seeking versatile sound.

Reuse and Low Maintenance

The rechargeable 1500mAh lithium battery with double protection board is designed for repeated charging cycles, supporting the speaker's portable use over time without requiring battery replacement. The physical button interface provides durable, wear-resistant control compared to touch-sensitive panels. With no complex software or apps required for basic operation, the speaker maintains functionality through straightforward manual controls.

Why Choose This Product

This speaker offers a combination of wireless Bluetooth convenience with traditional audio inputs, catering to users who have diverse music sources including TF cards and wired devices. The inclusion of FM radio extends its functionality beyond streaming services. The specified 8-hour battery life at moderate volume provides a clear expectation for usage time between charges. The choice of five colour options allows personalisation to match individual preferences or environments.
