uStream One: What's special

uStream One is a truly wireless pair of speakers (apart from the power cables). In fact, the two speakers communicate with each other like true wireless headphones.
There is no cable that connects the active master speaker to the passive slave speaker, as is often the case with this product type.
All you have to do is connect it to the mains and turn on each device. The first device powered on becomes speaker 1, and the second device becomes speaker 2. In a few seconds, they will connect to a Bluetooth playback source that will be paired with them as a single device.
uStream One: Design

These are high-quality wireless shelf speakers available in durable high-gloss piano black or piano white colors. Each speaker weighs 3.3 kilograms.
The Boomer of this model is a copper-colored magnesium alloy membrane combined with an exclusive neodymium magnet system, while the tweeter has a 28 mm textile dome in the purest audiophile tradition.
uStream One: Power output

Each speaker has a 50-watt Class D amplifier based on Texas Instruments modules. Speakers in a pair can be used together (100 watts) in stereo as well as separately for playback from different sources.
uStream One: Connectivity

Equipped with Bluetooth 5.0 wireless chips, the uStream One wireless speakers from Mitchell also offer full analog and digital connectivity: RCA, mini jack, optical digital and USB inputs.
The uStream One wireless speaker system can also play music from Bluetooth sources like smartphone, tablet or mp3 player, so simply install it on the shelf to get the proper stereo sound.
You can also connect your uStream One to your smart device through the Alexa app or google home app and specify your preferred Bluetooth speaker for playback. This means that the sound does not come from the device itself, but from your uStream One.
uStream One: Sound quality

The uStream One wireless speaker system features specially designed driver units that deliver a strong and powerful sound that negates the relatively small enclosures in which they are housed.
The speakers allow you to listen to every note through patented CLARI-t driver technology. Coupled with high frequency (treble) tweeter and proprietary designed woofer with metal alloy diaphragm, the speakers provide amazing sound, smoothly and with great controls.
While the best performance comes when they are used on the stands, uStream One will happily work on bookshelves or desktops or other AV furniture.

UStream One speakers are now available in Europe at a retail price of $600 (€499 / £450) on the websites of uStream One and Amazon.
