Bluetooth Aux Adapter, Car Aux Bluetooth 6.0 Receiver USB Audio Adaptor with 3.5mm Jack for 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 Good Great sound quality Strong Bluetooth connection Auto connects quickly The Bad Aux wire is a little thin I 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.

Brilliant bit of kit, I was worried it would ruin the sound quality but it’s very clear and doesn’t have any issues. Extremely easy to fit and use. Connects extremely quick and it plugs into a usb port so you do not have to worry about battery life I use it on a 2006 bmw and it’s brilliant

One of the best tech buys I’ve had. Bought to play music in my car from my phone. Once plugged in and connected it works the same as CarPlay. Super easy, the connection is great and no crackling, even at high volume. Would 100% recommend.

Excellent product, works great and connects within seconds, does exactly what it is designed for and is easy to setup in seconds. Audio quality is great considering the device is transmitting via Bluetooth then via an auxiliary port. The only downside and something anyone who is buying this product should take in to consideration is that the device will remain connected and in pairing mode even when vehicle is off if your vehicle has always on outlets which most vehicles do so something to consider as this will cause a battery drain if you forget to unplug USB element of the device. This is why I gave it a 4* rather than 5* as it does not explain this in the instructions when it really should

Works really well to connect Spotify on my phone to a 2016 Porsche Cayman's PCM via the aux jack and usb in the glove box. Signal seems strong and quality is good.

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.

Excellent little device, it gave me my music back in my Mercedes that only has an aux port. Connects fast, and sounds nice. It is a little quieter than an analogue cable but that is the nature of bluetooth. If your car has a call only bluetooth connection like mine, you can set your phone to send music only to the device and calls to the car to have the best of both worlds!

Needed to use this to effectively convert an Aux In plug on an amp into Bluetooth. Worked perfectly, just plug in to the mains with a regular USB A plug and works exactly as you'd hope. Easy to set up, seems high quality, no battery to worry about, no power switch etc. Spot on.
