Compact Bluetooth 5.3 audio adapter

The 1Mii ML300 is a 2-in-1 transmitter and receiver that adds wireless audio to TVs, PCs, gym equipment, home stereos, car systems or boat audio. It supports aptX Adaptive, aptX Low Latency and aptX HD codecs for high-definition sound with up to 80% lower latency, so video and game audio stay in sync when paired with compatible headphones.

Check your source and headphones first

Verify that your TV, PC or exercise gear has a 3.5 mm aux or 2RCA output for transmitter mode, or that your speaker system has a 3.5 mm aux or 2RCA input for receiver mode. Your Bluetooth headphones must support aptX Low Latency or aptX Adaptive to benefit from the low-latency claim, and aptX HD or Adaptive for the high-definition audio claim. The adapter is backward compatible with Bluetooth 5.2, 5.1, 5.0, 4.2, 4.0, 3.0 and 2.0 devices.

Pocket-sized build with dual 3.5 mm and RCA

The unit measures 1.96 x 1.37 x 0.31 inches and weighs 5.28 grams, making it easy to carry in a pocket or bag. A built-in rechargeable battery provides 12 hours in transmitter mode and 15 hours in receiver mode on a single charge. Both 3.5 mm aux and 2RCA cables are supported for wired connections, and a double-click of the Bluetooth button cycles through SBC, aptX Low Latency, aptX HD and aptX Adaptive codecs without needing an app.

Questions about this item

What comes in the box and what do I need to supply myself?

The unit ships with the ML300 adapter, a 3.5 mm auxiliary cable and a pair of RCA cables. You must provide your own Bluetooth headphones or speakers that support aptX Low Latency, aptX HD or aptX Adaptive to use the low-latency or high-definition codecs.

Should I choose the transmitter or receiver mode for my setup?

Use transmitter mode (TX) to send audio from a non-Bluetooth TV, PC, gym machine or airplane seat to wireless headphones. Switch to receiver mode (RX) to stream music from a phone or tablet to a wired home stereo, car audio system or powered speakers.

What does the 80 % lower latency claim mean when I am watching TV?

With aptX Low Latency the audio delay is reduced by roughly 80 % compared with standard SBC, so dialogue stays in sync with the picture provided your headphones also support aptX Low Latency or aptX Adaptive.
