2-in-1 Bluetooth 5.3 Transceiver

The 1Mii ML302+US is a dual-mode Bluetooth 5.3 audio adapter that works as a transmitter or receiver. It adds wireless streaming to non-Bluetooth TVs, PCs, projectors or gym equipment, and it upgrades wired stereos or speakers with Bluetooth input. Two headphones can be paired simultaneously for shared listening. The built-in rechargeable battery delivers up to 30 hours of playback per charge.

3.5 mm AUX and RCA Connectivity

A 3.5 mm AUX port and a pair of RCA jacks provide both input and output paths, so the unit slots into almost any line-level audio chain without extra cables. In transmitter mode it connects to an audio-out jack; in receiver mode it connects to an audio-in jack. A tactile volume button on the device gives immediate level control without reaching for the source. The compact 2.95 x 2.17 x 0.78 inch enclosure sits discreetly beside the host gear.

aptX Adaptive and Low-Latency Codecs

Support for aptX Adaptive, aptX HD, aptX Low Latency, AAC and SBC keeps audio synchronised with video when watching films or gaming, provided the headphones also support the relevant codec. The 300 mAh battery recharges in about three hours. Buyers who need optical or HDMI audio interfaces, multi-room streaming or a permanent mains-powered installation will need a different solution.
