UGREEN Bluetooth Aux Adapter, Car Aux Bluetooth 5.4 Receiver USB Audio Adaptor with 3.5mm Jack for Car or Home Stereo Music Streaming Built-in Microphone Plug and Play Auto on Handsfree Car Kit

This tiny BT receiver allows two devices to be paired with it at the same time. The last one to send audio to it seems to take it over (even if currently the other device is using it). That's how I prefer it. I installed it hidden in the car, and I use it with an iPad at times, and the phone at other times. There's no pairing button on the BT receiver, which is a good thing if you install it hidden away. (Behind the car audio head unit.) I wired it to be powered on and off together with the car audio. So as soon as I turn off the car, the phone is not trying to use the BT receiver. Turning on power connects it very quickly to the devices. Audio quality seems ok (even supports AAC). Perhaps a bit light in the lower frequencies.

Excellent device. Easy setup, Works instantly, great quality sound. Can't recommend highly enough

Worked a treat on old JVC car stereo .Was using usb-c to aux but phone mic wouldn't work so desperately needed Bluetooth. This cable is brilliant. Plugged into stereo , searched BT on phone and connected straight away with no fuss.Sound is really good and phone calls go through stereo while using phone mic . The coiled cable is very thin so don't know about longevity ( but once plugged in you can forget about it ) overall really happy with purchase

No issues or concerns, simple to use. Have tried other bluetooth devices in the past that break after a couple weeks due to their design. So far so good.

I have a 2012 Mini that has Bluetooth, but only for phone calls (not for audio streaming), a USB port that only recognises old iPods (not newer smartphones) and a 3.5mm aux input next to the USB.I needed a solution to be able to play music, podcasts and navigation directions from my phone to the car speakers, but I didn’t want to have loads of wires trailing around the dashboard.This adapter from UGreen is pretty much perfect for the job. In my car with the USB and aux input next to each other, it tucks away under the dash in front of the gear lever, there’s just one tiny blue LED that doesn’t distract when driving in the dark and the sound quality is exceptional. Providing you have the volume turned up on the phone, it’s plenty loud enough with no interference or distortion, and the fact that it’s powered from the USB means you never have to worry about charging a battery. I’ve made a couple of phone calls in the car, and the people I’m calling have said the microphone quality is good, too (which I find amazing as the USB is low down in the car, quite a distance from my mouth).The only downside (and I think this is more to do with how the car’s USB is powered rather than the UGreen unit itself), is that the unit does not immediately power off when the ignition is turned off. There’s a delay of a few minutes, so your phone remains connected and continues to play the current podcast / music selection, even though the car speakers are no longer powered, for as long as the unit is powered on or your phone is within Bluetooth range of the unit.If I plug the USB into the 12v adapter I use for charging my iPhone instead of the car’s inbuilt USB, the UGreen unit powers down within a few seconds, but this is not quite as neat as plugging into the car’s own USB socket.But apart from that, I’m really impressed. For £12, this is a really good value solution to get Bluetooth streaming into an older car.

Great product, very easy to use, easy to set up, my phone links to it straight away when I get into the car. Great for hands free phone calls and streaming music as I drive.

The media could not be loaded. So this UGREEN Bluetooth Aux Adapter is sold as a Car Aux Bluetooth adapter, but it will work with other things like HiFi's.I purchased this as I have a HiFi that is quite good but does not have Bluetooth built in and I wanted to stream online radio and Spotify etc from my phone to the HiFi. At first as a workaround I was connecting a 3.5mm to 3.5mm AUX cable from my phone to the AUX input on my HiFi and this works Ok but the phone has to sit connected to the HiFi.I was looking for something that did Bluetooth that could connect to my HiFi and found this Ugreen adapter.This adapter is a 3.5mm socket on one end and a USB plug on the other. Its designed and sold for use in a car as you would plug the USB end into a USB power socket and the 3.5mm AUX connector would link into the AUX input on your car radio. The USB connector is to power the device up.I wanted it for my HiFi so I connected the 3.5mm plug to the AUX input on the HiFi and plugged the USB end into the USB socket on my HiFi, as it has a socket so you can plug in and play audio from a USB stick, but these USB sockets provide power also. You then just pair with your phone, select the AUX input on my HiFi and I was able to play music from my phone to the HiFi via Bluetooth, no cables !Its worth noting that if my HiFi did not have a USB socket then I could connect the USB end to a USB power plug and it would work the same, as the USB socket is just to power the device.Setup was quick and easy and once you link the Ugreen then it will just work and play the audio to the HiFi as long as it is switched on and connected to AUX.Walking around my house it has a range of apx 10m, which is as advertised.This is sold as Bluetooth version 5, and I have an older Samsung phone and this worked fine with that phone.The audio quality is excellent, no static or humming, as you some times get this with cheap audio adapters.I believe this also enables you to answer calls as well via this as it has a built in microphone on the USB end, but as I am not using it in a car I have not tested this function myself.
