UGREEN Bluetooth Aux Adapter 3.5mm for car audio 🎧

This Bluetooth aux adapter from UGREEN turns a car or home stereo with a 3.5 mm input into a wireless audio receiver, making it easy to stream music and take calls while driving or relaxing at home. It draws power from a USB‑A port so there is no internal battery to charge, and it includes a built‑in microphone for hands‑free calls and voice navigation, which helps keep attention on the road.

Key Points

The unit pairs using Bluetooth 6.0 which, according to the manufacturer, aims to deliver a faster transmission and a more stable connection than earlier versions. Playback uses the A2DP profile for audio streaming, so you can play music from services such as Spotify or playlists stored on a phone. The small aluminium body and short elastic TPE cord make it compact and simple to route in a vehicle or near a home stereo, and the plug‑and‑play operation means little setup is required. Note that this product is a receiver only and is intended to connect to devices that accept a 3.5 mm audio input. Also consider that compatibility can vary if the car charger’s USB‑A plug is unusually large.

Usage Recommendations

For use in a car, insert the 3.5 mm plug into the stereo aux port and plug the USB‑A into a vehicle USB socket for continuous power. Keep the adapter within a few metres of the source device to maintain a reliable connection. If the USB‑A plug does not fit comfortably into your charger, try a different USB port or a slimline adapter to avoid mechanical interference. For home stereo setups, the same arrangement applies, and the device can serve well for casual listening when a wired input is the only option.

Positive Aspects

The compact format reduces clutter and the aluminium finish feels robust. Hands‑free calling is practical for short conversations while driving and the lack of an internal battery eliminates the need to recharge the dongle between uses. Expect clear audio when using compatible streaming apps, though ultimate sound quality will depend on the car or speaker system and the streamed source material.
