Wireless Bluetooth Speaker Square U Disk Portable Small Speaker with USB Interface

This wireless Bluetooth speaker is a compact audio device designed for portable use. It connects via Bluetooth 4.0 and also offers a USB interface for U disk playback, giving you two ways to play audio. The square shape and small dimensions of 117 x 79 x 39 mm make it easy to place on a desk, shelf, or table. It is available in five colours: black, blue, green, grey, and red. The built-in 300mAh lithium battery provides a stated playing time of 1, though the unit is not specified in the source text. The speaker has a single channel and one speaker unit, with an output power of 3W and a frequency response range of 100Hz to 20kHz. The signal to noise ratio is at least 75dB. With an effective distance of 10 metres, you can move around a room while staying connected. The button operation mode keeps controls simple. Expansion storage via U disk supports up to 32GB. This speaker suits short listening sessions, personal audio, or as a secondary speaker for small spaces.

Features and Construction

The speaker is built around Bluetooth 4.0 and a USB interface. It includes a built-in lithium battery and button controls. The square form factor and compact size are key physical traits. The source text does not specify casing materials or construction details beyond these functional elements.

Material and Build

The source text does not state the materials used for the speaker casing, grille, or buttons. It does confirm a built-in lithium battery, a USB interface, and button operation. The speaker is described as having one channel and one speaker unit. No further construction details are provided, so no claims can be made about durability, finish, or specific build quality.

Size and Practical Fit

The speaker measures 117 x 79 x 39 mm, which is a compact square size. This makes it suitable for placing on a desk, bedside table, or shelf without taking up much space. It is small enough to be portable, though no weight is given. The 10-metre effective Bluetooth distance means you can keep your device nearby or across a small room. The available colours are black, blue, green, grey, and red.

Uses and Placement

This speaker can be used for personal audio playback from Bluetooth devices or via U disk. Its small size and square shape allow it to fit into various spots around the home or office. The 1-hour stated playing time (unit unspecified) suggests it is best for shorter sessions rather than all-day use.

Event or Professional Use

With a 3W output and a single speaker, this is not intended for large rooms or parties. It may be suitable for a small presentation, a desk in a quiet office, or as a backup speaker for a laptop. The 10-metre range gives some flexibility, but the 1-hour playing time limits extended use. For professional settings where long battery life is needed, this speaker may not be ideal.

Everyday Home Use

At home, this speaker can be used in a kitchen, bedroom, or study for listening to music, podcasts, or internet radio from a Bluetooth phone or tablet. The USB interface lets you play files from a U disk without needing a Bluetooth connection. The button controls are straightforward. The five colour options allow you to choose one that fits your space. The 1-hour playing time means you may need to recharge frequently for longer listening.

Benefits and Buying Value

The main practical benefits are Bluetooth 4.0 connectivity, USB U disk playback, and a compact square design. The built-in 300mAh lithium battery and 3W output are modest specifications suited to personal listening. Expansion storage up to 32GB adds flexibility for stored audio files.

Reuse and Low Maintenance

The rechargeable lithium battery can be reused by charging via the USB interface. The source text does not provide charging time or battery lifespan. No specific maintenance instructions are given, so care should be limited to keeping the speaker dry and clean according to general electronics practice. The button operation and USB port should be kept free of dust and debris.

Why Choose This Product

This speaker offers a combination of Bluetooth and U disk playback in a small square format. It is available in five colours and supports up to 32GB expansion storage. The 10-metre range and 3W output are clearly stated. The playing time is listed as 1, but the unit is not specified, so buyers should be aware of this ambiguity. The Bluetooth version is 4.0, which is an older standard compared to newer versions. This product is best suited for basic, short-duration audio playback where a compact size and U disk option are useful.
