ElecMoga aptX Adaptive Bluetooth 5.4 transmitter for TV

This compact Bluetooth 5.4 transmitter and receiver combines versatile audio routing with low-latency codecs for watching films, gaming and listening on the move. It serves as a handy 2-in-1 wireless aux adapter that lets you send audio from non-Bluetooth sources to headphones or receive audio to a stereo from a phone, making it useful in the home, car or on flights.

Key Points

This device functions in both TX (transmit) and RX (receive) modes, so a TV or desktop without Bluetooth can stream to wireless headphones, and a phone or tablet can play to a non‑Bluetooth stereo. According to the manufacturer, Bluetooth 5.4 and a high-end QCC chip improve connection stability and reduce latency, while support for aptX Adaptive, aptX HD, aptX LL, aptX and SBC helps keep audio in sync for movies and games. Dual connection is available, letting two headphones pair in TX mode or two phones in RX mode for sharing audio, though simultaneous playback from two phones may require pausing one device to avoid lag. The built-in 300 mAh battery offers up to 16 hours in receive mode and around 12 hours in transmit mode under dual-connectivity conditions, and a full charge is achieved in approximately 2 hours.
