Transmitter & Receiver for Travel

The Wothfav BT-20 is a 2-in-1 Bluetooth 5.3 wireless audio adapter that connects to any 3.5 mm AUX port. It streams audio from TVs, airplane seats, gym equipment or gaming consoles to Bluetooth headphones in transmit mode. In receive mode it adds Bluetooth input to wired speakers or car stereos from a phone or tablet.

Compact ABS Build with AUX Connection

The unit measures 4.72 by 1.18 by 0.59 inches and weighs very little, housed in white acrylonitrile butadiene styrene plastic. A single 3.5 mm auxiliary cable links it to the source or output device, so no proprietary connectors or mounting hardware are required. LED indicators show pairing status and mode selection at a glance.

25+ Hour Battery and USB-C Charging

The internal battery delivers over 25 hours of continuous playback on one charge, covering long flights or road trips. Fast USB-C replenishment keeps downtime short, while built-in protection guards against overcurrent, overheating and short circuits. Bluetooth 5.3 keeps latency low for synchronized video and audio.
