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

A great device that sounds good, is easy to set up, and auto connects right away when you are back in the car.The GoodGreat sound qualityStrong Bluetooth connectionAuto connects quicklyThe BadAux wire is a little thinI have used many aux Bluetooth adapters in the past and have usually been disappointed but this item is now my favourite. I avoided battery-powered adapters as they never last more than a few hours and you end up always keeping them plugged in anyway. Other devices where the aux jack is attached to the device end up breaking after a few months making the item useless, which is why I chose this item.You need an aux and USB connection for this to work but that suited my needs so was not a problem. Once plugged into my car it immediately shown up on my phone to connect and I had no problem with pairing. This item is stored within an arm-rest box on my car but I had no problem with signal or connection dropping out, even after a 4-hour car journey. Finally, when I am back in my car after leaving, my phone re-connects quickly and auto-plays any music I was listening to.This device also plays basic messages through the speakers such as 'power on' etc so you know the device is on. In regards to sound quality, it sounds better than my FM radio but could not comment from an audiophile perspective as it is used in a car with stock speakers and the audio source is from music streaming services.My only niggle is the aux cable is a little thin and could be a problem in the future. Time will tell.Overall I am very happy with this purchase and would recommend it to others. It should suit the needs of 99% of car owners looking for a Bluetooth solution for their car that may only have an aux and USB connection.

Great product and works very well.

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

Once paired connects automatically which is better than last one I had. Doesn’t work well for calls, but it’s good for music. My previous one had a battery which kept it functional with the engine off, this doesn’t. I found it gets very hot but could be the fault of the usb charger/12v socket so I’ve ordered a new one. I’ve a feeling the sound quality isn’t quite as good as previous battery powered one but I’m not 100% on that

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.

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.

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

Quite amazing. Seamless connection works like a charm. The only issue is the wire.. it's quite delicate & thin. If somehow get between anything it will get damaged very easily
