Versatile 2-in-1 Audio Adapter

The YOCOWOCO RT3 is a Bluetooth 5.2 transmitter and receiver designed for travellers and home users who want wireless audio from non-Bluetooth sources. In transmitter mode it streams sound from seat-back screens, tablets or gym equipment to two pairs of headphones simultaneously. In receiver mode it adds Bluetooth input to wired speakers, car stereos or boat systems. A built-in microphone enables hands-free calls when connected to a phone.

Compact Clip-On Build With OLED Feedback

Measuring 2.2 by 1.2 by .59 inches and weighing .69 ounces, the unit clips to a lapel or seat pocket for easy access. A 3.5 mm auxiliary cable links the adapter to the source or speaker, while a USB-C port handles charging. The OLED panel shows active mode, volume, codec — including aptX Low Latency — battery level and the names of both paired devices, removing guesswork during pairing.

Replaces Wired Dongles And Single-Pair Adapters

The RT3 upgrades from basic airline plugs or single-connection dongles by supporting dual headphone output and aptX Low Latency for tighter lip-sync. Battery life reaches 25 hours in transmit mode and 20 hours in receive mode, with charging-while-playing for longer trips. Buyers who need more than two simultaneous connections or a dedicated aptX Adaptive implementation will need a different solution.
