1Mii B03 Bluetooth 5.3 Transmitter Receiver aptX Adaptive Low Latency HD Optical RCA AUX Volume Control

Versatile Transmitter & Receiver

The 1Mii B03 adds Bluetooth 5.3 to a TV or stereo system. In transmitter mode it streams audio from a TV, DVD player or similar source to Bluetooth headphones or speakers. In receiver mode it lets a wired stereo play music from a phone, tablet or laptop. The adapter supports aptX Adaptive, aptX Low Latency and aptX HD codecs.

Range & Dual-Headphone Limits

Outdoors the unit reaches up to 230 ft (70 m) line-of-sight; indoors the practical range is 80110 ft (2535 m). Two headphones or speakers can be paired at once, but when both use aptX Low Latency the codec falls back to standard aptX. Optical, RCA and 3.5 mm connections provide digital and analogue paths.

Simple Setup & Common Issues

Power comes from a 5 V supply and the box measures 6.15 in x 3.15 in x 1.86 in. Switch between TX, RX and bypass modes with the hardware toggle, then pair devices using the front button. Volume is adjusted on the unit itself. No remote control is included, so all changes must be made at the device.
