uStream One
True Wireless Bluetooth Stereo Speaker System — 2-Way
SOUND The uStream One runs a two-way driver array — a silk-dome tweeter handling the top end and a magnesium alloy woofer taking everything below. Each has its own dedicated amplifier. At 50W RMS per channel the soundstage sits where you placed the speakers and stays there regardless of what is playing. This is what a stereo pair is supposed to do.
BUILD The cabinet is finished in black wood grain vinyl that absorbs rather than reflects. The proprietary voice coil runs a 20oz neodymium magnet — the same specification found in speakers at significantly higher price points. It produces bass without a subwoofer because the driver was designed to, not because the marketing says so.
CONNECTIVITY The OPTICAL Toslink and HDMI ARC inputs mean the One connects directly to any television without adapters. Place one speaker either side of the screen, connect via HDMI ARC, and control everything with your TV remote. RCA inputs handle a turntable or CD player. The 3.5mm jack takes anything else.
BLOCK 4 — SMART HOME Pair to Amazon Alexa or Google Home for voice control across the room. Connect a WiiM Mini to unlock AirPlay 2, hi-res audio, and multi-room streaming — the One becomes the output for an entire home audio system without a single additional cable.
