Currently, 1Mii has more than 10 million users, with products covering audio accessories, Bluetooth headphones, and HiFi audiophile devices.

The latest Bluetooth 5.3 technology in the 1Mii ML300 Bluetooth Transmitter Receiver enables backward compatibility with Bluetooth 5.2/5.1/5.0/4.2/4.0/3.0/2.0, delivering more stable wireless connections to your devices. Equipped with advanced aptX Low Latency technologies, the ML300 can provide up to 80% lower latency, ensuring high-quality sound without audio-video sync issues, whether you're gaming or watching movies.

Offering a 2-in-1 functionality, the ML300 can be used as both a Bluetooth transmitter and receiver. In transmitter mode, it's easy to turn a non-Bluetooth TV, PC, gym/flight equipment into a Bluetooth transmitter. In receiver mode, it can stream music to speakers, car, or home stereo systems without built-in Bluetooth.

The ML300 supports devices with 3.5mm aux/2RCA audio jacks, providing wide compatibility. It also boasts impressive battery life, delivering up to 12 hours in transmitter mode and 15 hours in receiver mode on a single charge.

When using the ML300 with Bluetooth headphones, ensure your headphones also support aptX Low Latency to achieve low latency. If they use a different codec (e.g., SBC, aptX), a 70-200ms audio delay may be noticeable.

If you encounter pairing issues, turn off Bluetooth on all mobile phones or PCs in the house, and make sure your headphones/speakers are not automatically paired with other devices during the pairing process. For first-time pairing, keep the distance within 1 meter. If problems persist, reset both the ML300 and your Bluetooth devices to factory defaults.

The ML300 is not recommended for live music or musical instruments like guitars or pianos; specialized adapters are better suited for those applications. To change the audio codec, double-click the Bluetooth button #1 to cycle through SBC (blue), aptX Low Latency (white), aptX HD (green), and aptX Adaptive (yellow).

The ML300 is compatible with AirPods but not with AirPods Pro 2nd Gen. It does not have a built-in microphone, so it does not support online calls or conferencing with a headset. Ensure your TV has a 3.5mm AUX AUDIO OUT, Headphone jack, or 2RCA AUDIO OUT for the ML300 to work properly.

To reset the 1Mii ML300, press and hold the Bluetooth button #1 for about 7 seconds until the LEDs flash purple for 3 times.
