Bluetooth 5.4 Aux Receiver

The SMUGDESK Bluetooth 5.4 Aux Audio Receiver adds wireless streaming to any car stereo or home speaker system with a 3.5mm input. It draws power from a USB port and pairs with phones or tablets for music and podcast playback.

Hands-Free Calling

A built-in microphone enables clear hands-free calls while driving, automatically switching from music to call mode when the phone rings. Bluetooth 5.4 provides a stable, low-latency link that resists interference during daily commutes.

3.5mm Wired Limit

Audio quality and connection stability depend on the 3.5mm auxiliary cable between the adapter and the speaker system. The link cannot carry digital metadata or multi-channel formats supported by native Bluetooth speakers.

Questions about this item

Will the Bluetooth 5.4 receiver work with my older car stereo that only has a 3.5mm aux input?

Yes, the adapter connects via the 3.5mm aux jack and draws power from any USB port, so it adds Bluetooth 5.4 streaming to any stereo with an aux input.

How can I confirm the Bluetooth 5.4 link is active and the built-in microphone is picking up my voice?

After pairing, the phone shows a connected Bluetooth device; during a call the audio routes through the car speakers and the caller hears you through the embedded mic.

What comes in the box and do I need to buy any cables or a power adapter separately?

The kit includes the Bluetooth 5.4 receiver with its 3.5mm aux plug and a USB power cable; no extra cables or charger are required if your car has a USB port.
