Wireless TV audio transmitter

The 1Mii B06TX adds Bluetooth 5.3 to any television that lacks it, sending sound to wireless headphones or speakers. It accepts 3.5 mm, RCA, optical or coaxial outputs so older sets can be used without replacement. The unit is a transmitter only and cannot receive audio from a phone or tablet.

Range and latency in daily use

Dual antennas deliver up to 197 ft line-of-sight and 50–70 ft indoors through walls. aptX Low Latency removes lip-sync delay when the headphones also support the codec; otherwise some delay remains. aptX HD provides higher-quality audio with compatible headphones. The adapter draws 5 volts from a USB port or charger.

Volume knob and dual pairing

A front-panel volume control adjusts the wireless level independently of the TV remote. Two Bluetooth buttons pair separate headphones or speakers simultaneously, though connecting two aptX Low Latency devices switches the codec to standard aptX. Optical or coaxial inputs require the TV audio output to be set to digital.

Questions about this item

How do I connect the 1Mii B06TX to my TV using the 3.5mm AUX, RCA, optical or coaxial outputs and which step is often missed?

Plug the transmitter into 5 V power, connect the matching cable to the TV's audio output, press the power button and set the TV audio menu to optical or digital output when using optical or coaxial; many users forget to change that TV setting.

What ongoing maintenance or replacement will the 1Mii B06TX need?

The unit has no user-replaceable parts or batteries; keep the vents clear of dust and ensure the 5 V power supply remains functional.

What is the first range limit I will hit with the 1Mii B06TX during sustained use?

Expect up to 197 ft in open space and 50–70 ft indoors with walls; obstacles and Wi-Fi interference reduce the practical distance first.
