uStream Cube Wireless Stereo Bookshelf Speakers with HDMI ARC & Bluetooth

The uStream Cube Wireless Stereo Bookshelf Speakers with HDMI ARC and Bluetooth are created to deliver authentic hi-fi stereo sound in any space, without messy wiring or complex installation. Each Cube is a fully active, identical speaker, and once powered on they automatically connect to one another to create instant left and right channel separation. There’s no app to install, no Wi-Fi setup and no cable linking the two units, just straightforward, seamless audio from the start.

Compact enough to sit comfortably on a shelf or desk, the Cubes produce a surprisingly expansive and immersive soundstage. Deep, punchy bass, smooth midrange clarity and crisp, detailed treble combine to create a balanced and engaging listening experience. The custom 4-inch magnesium-alloy driver, driven by a substantial 20oz neodymium magnet, delivers low-frequency performance that exceeds expectations for their size, removing the need for a separate subwoofer in most rooms. Positioned either side of your television and connected via HDMI ARC or auxiliary input, the Cubes provide genuine stereo separation, offering a far more cinematic and spacious sound than a traditional single-unit soundbar.

Designed to fit effortlessly into modern lifestyles, the uStream Cube works seamlessly with smart home systems. You can assign the speakers as the default output for Amazon Alexa or Google Home, enabling convenient hands-free stereo playback through voice control. Bluetooth 5.3 connectivity makes wireless streaming from phones, tablets and laptops simple, while HDMI ARC allows a clean, single-cable connection to your TV. Additional inputs also make it easy to connect games consoles, media players and other devices.

Practical details enhance everyday usability. The mid and bass driver features a child-safe dust cap to help prevent accidental damage, and premium finishing touches such as an aluminium remote control and multiple input options add convenience and flexibility. A reassuring two-year warranty provides added peace of mind. In the box, you’ll find two active black-finish speakers, power adaptors with regional cables, an EU-UK adaptor, an aluminium remote control, an RCA to 3.5mm cable and a quick start guide, ensuring you can begin listening straight away.

Powered by 70W RMS of clean digital amplification from Texas Instruments, with a frequency response spanning 30Hz to 18kHz, Bluetooth 5.3 with 24/48 capability and a signal-to-noise ratio above 75dB, the uStream Cube delivers performance that competes with much larger and more expensive hi-fi systems. Each speaker measures 150 × 200 × 180mm and weighs 3.6kg, making them ideal for desks, shelves or TV units alike.

The uStream Cube demonstrates that true stereo sound still makes a difference. Compact enough for smaller spaces yet powerful enough to transform your living room, and versatile enough to replace a soundbar entirely, it offers a simple and stylish way to enjoy genuine hi-fi audio throughout your home.
