Introduction
1 mii B03 is a wireless long range audio transmitter & receiver incorporating the latest “AptX low-latency’ technology for CD-like quality sound with virtually no delay. Multifunctional, supporting optical, bypass and voice prompts. Providing the best solution to enable your TV or home audio system to wirelessly stream hi-fi audio directly to any wireless headphones or speakers.
To take advantage of the better performance of the APTX Low Latency Codec, the other side device must support the same codec. If the other side device only supports the normal AptX codec, or the SBC one, those codecs will be used instead.
