1Mii 3-in-1 Wireless Audio Transmitter & 2 Receivers – 320ft Range, 20ms Latency

Meet the 1Mii 3-in-1 Wireless Audio Kit

The 1Mii 3-in-1 wireless audio kit combines a compact transmitter with two receivers inside a durable metal shell. It handles optical, coaxial, and 3.5 mm connections, so you can send sound from your TV, computer, or AV processor to powered speakers, subwoofers, or soundbars without running long cables.

One TX is designed to wirelessly feed two RX units, enabling two speakers to play from the same source at the same time. The rugged metal enclosure helps guard against bumps in a living room or media area, while the automatic power-on feature makes setup simple: connect power, and the kit powers up and reconnects whenever you turn on your source.

Why this kit stands out

• The 3-in-1 design pairs a transmitter with two receivers to cover multiple listening zones.
• Long-range performance reaches up to 320 feet outdoors and 100–165 feet indoors, with two receivers active simultaneously.
• Low latency under 20 ms delivers tight synchronization with video content and clear, stable audio.
• Flexible connections include optical, coaxial, and 3.5 mm (RCA) inputs/outputs to fit most home setups.
• Cable-free listening can reduce clutter around your TV stand or entertainment center.
• Note: HDMI input is not supported; RT5066Pro transmits audio only and should connect to powered speakers or amps.

How to use it in daily life

Imagine turning your living room into a mini home theater: your TV audio feeds two powered speakers for immersive stereo without tangled wires. In a home office, you could stream PC sound to a desktop speaker at your desk and a bookshelf speaker in another room. In the backyard, the system can handle a wall speaker or a portable outdoor setup for lively gatherings.

To set up, connect the TX to your source via optical, coaxial, or 3.5 mm, connect each RX to a speaker, and power both units. They will auto-detect and establish a link, so you can start listening within moments. For best results, keep away from large metal obstacles and note that range varies with walls and routers nearby.

Important note

RT5066Pro is designed for audio transmission only; it is not an amplifier. Pair this kit with powered speakers, subwoofers, or power amplifiers to realize its wireless potential.
