What it is and who it fits

A 2019 USB wireless Bluetooth4.2 3.5mm audio stereo receiver in black. It adds Bluetooth connectivity to speakers, headphones or a car AUX input that lack it. The tiny 2.9×1.4×1cm plastic dongle draws 5 V from any USB charger, PC or powerbank. Buyers who need aptX, AAC or memory-card playback should look elsewhere.

Capacity and headroom

The single 3.5 mm analogue output feeds one wired device at a time. Pair a smartphone or tablet to stream music, video or game audio wirelessly. Range and stability follow the Bluetooth4.2 specification; walls or interference will reduce usable distance. No internal battery means continuous USB power is mandatory.

Thermals noise and power

Passive operation with no fan keeps the unit silent. A blue LED indicates the pairing and connection state. Power draw is limited to the 5 V USB supply; the adapter stays cool during normal use. No high-definition audio codecs or Wi-Fi hardware are present.

Questions about this item

Will this Bluetooth4.2 receiver work with my older car stereo that only has a 3.5mm AUX input?

Yes, it plugs into any 3.5mm AUX port and draws power from a USB charger, power bank or PC USB port so it works with older stereos that lack Bluetooth.

How do I know the XFN0433 receiver is paired and playing audio correctly?

The blue LED indicator shows the working status; once paired with your phone or tablet the light confirms the link and audio plays through the connected speaker or headphones.

Does the package include a 3.5mm audio cable or must I buy one separately?

A 3.5mm cable is listed in the specification, so the receiver, cable and USB power connection are all provided in the box.
