Bluetooth 5.3 Transmitter Receiver Adapter

This 2-in-1 Bluetooth 5.3 adapter connects to any 3.5 mm AUX port and works as a transmitter or receiver. It streams audio wirelessly from devices such as in-flight entertainment, gym equipment, TVs or gaming consoles to wireless headphones. A Qualcomm chip supports SBC, AAC, aptX, aptX-LL and aptX-HD codecs for low-latency, high-fidelity stereo sound. The wireless range reaches 10 m / 33 ft.

Travellers and home listeners wanting wireless audio

Ideal for flyers who want to use personal wireless headphones with seat-back screens, or for anyone adding Bluetooth to a car radio, home stereo or amplifier. It pairs two headphones simultaneously for shared listening. Not suited for users who need a USB audio interface, a dedicated DAC, or a transmitter with optical or RCA inputs. Buyers requiring aptX Adaptive or LDAC support should look elsewhere.

Simple controls and battery-saving features

The adapter enters pairing mode automatically on power-up; a blue LED indicates transmitter mode and a red LED indicates receiver mode. An on/off switch conserves battery life and a reset button restores defaults. The supplier recommends turning off nearby Bluetooth devices such as phones when pairing in receiver mode to avoid interference.
