Bluetooth Transmitter Receiver for TV and Home Stereo with Optical, RCA and AUX Audio Connections

The 1Mii B03 Bluetooth transmitter receiver sends TV or home stereo audio to Bluetooth headphones or speakers and can also receive music from a phone, tablet, laptop, or desktop. Optical, RCA, and 3.5mm AUX inputs and outputs support flexible connection to compatible audio equipment.

In TX mode, the B03 can send audio to a pair of Bluetooth headphones or speakers while also feeding a wired external speaker or soundbar. The documented range is up to 230 ft (70 m) line of sight outdoors and 80–110 ft (25–35 m) indoors. aptX Low Latency and aptX HD are supported when the receiving equipment supports the corresponding codec.

For optical transmission, set the source to PCM or stereo; Dolby and DTS input are not supported. The adapter does not transmit and receive simultaneously, has no microphone for headset calls, and aptX HD and aptX Low Latency cannot operate at the same time.

Frequently Asked Questions

Can the B03 send TV audio to headphones and a wired external speaker at the same time?

Which audio connections does this Bluetooth transmitter receiver use?

It supports optical, RCA, and 3.5mm AUX inputs and outputs for compatible audio equipment.

What optical audio setting is required for TV transmission?

Set the optical source to PCM or stereo; Dolby and DTS input are not supported.

Does the B03 support simultaneous transmitting and receiving?

No. The documented notice states that it does not support simultaneous transmit and receive functions.
