The M126 audio transmitter and receiver operates in two modes: as a transmitter, it sends audio from a TV or computer to Bluetooth headphones or speakers; as a receiver, it receives audio from a smartphone or tablet for playback on a non-Bluetooth audio system. It connects via a 3.5 mm AUX cable and supports Bluetooth 5.0, with a range of up to 10 m. The rechargeable battery provides up to 8 hours of continuous use, and its buttons let you switch between modes.
