USB audio transmitter receiver for car and home

This adapter connects non-Bluetooth audio sources such as a TV or PC to Bluetooth headsets or speakers using a 3.5 mm auxiliary cable. It also receives audio from a smartphone or tablet and sends it to wired headphones, car audio systems or home speakers. The device is powered by a USB 5 V supply and includes a built-in microphone for hands-free calls. A single button switches between transmitter and receiver modes.

Suits users who want wireless audio from legacy

Buyers who need to stream audio from older equipment to Bluetooth headphones or speakers will find this adapter useful. It also works well for adding Bluetooth input to a car stereo or wired speaker system. Users who require video transmission, file transfer or multi-room audio synchronisation should look elsewhere because the adapter handles only stereo audio.

3.5 mm auxiliary interface for stereo audio

The sole wired connection is a 3.5 mm AUX port that carries stereo sound in both directions. Transmitter mode sends audio from the source through the cable to the Bluetooth link, while receiver mode routes Bluetooth audio back through the same cable to the output device. The USB port provides power only and does not carry audio signals.

Questions about this item

What devices can the 3.5 mm AUX cable connect to for audio input or output?

The 3.5 mm AUX cable plugs into any device with a matching 3.5 mm auxiliary port — TV, PC, CD or DVD player, smartphone, tablet, Bluetooth TV, speaker, headphones or car audio system — to send or receive stereo audio.

How do I switch between transmitter and receiver modes on the adapter?

Power the adapter via USB 5 V; it starts in transmitter mode with a red flashing LED. Long-press the function button until the LED changes to blue flashing — that puts it in receiver mode. Press again to toggle back.

What ongoing care does the adapter and its included cable need?

No scheduled maintenance is required. Keep the USB plug and 3.5 mm connectors free of dust and debris; if the AUX cable becomes damaged or the adapter stops pairing, replace the cable or the unit.
