UGREEN AUX Bluetooth 5.4 Adapter for Car, Bluetooth Receiver for Car/Home Stereo/Speaker/Wired Headphones, Bluetooth Car Receiver AUX, Handsfree Call, Dual Device Connection, 15 Hour Playtime

For £15, the sound quality and connection stability, which are the two things most important to me are virtually flawless.Connecting via an iPhone 13, I have been using the device for a number of months and my only main complaint is that the microphone for calls is pretty bad,I will expand on that, you have to be in a pretty much silent place in your car. So pulled over in a parking spot with your engine not running. It will work for receiving and making calls, just don’t expect great voice pickup from the built in mic.I didn’t plan on using it for calls anyway, just for streaming music from my phone to my car via the 3.5mm jack. For this, the device is excellent m, with great audio quality and no drop outs.This would be a 5 star review, but it loses a star for the poor quality microphone.Lastly, the battery is great though I have a 12 volt input connector right next to the 3.5mm input in my car, so I leave it permanently plugged in using a 12 volt to two usb adapter which you will need to power it or charge it in the car. If your car has usb, then you can use this, however I would imagine if you have a usb input on your car, you probably don’t need this bt transmitter in the first place, as most usb connectors on cars allow you to connect your phone and access your music that way, simply with plugging in a cable. Easy mode!

Works really well, used on a stereo system which is approx. 10 years old, wanted something to connect phones and tablets to play music to it and this is easy to use. Clear sound and no interruption.Plug and play, charge it (Charge lasts a long time) and plug it in, once turned on it will appear on your Bluetooth menu. Also used to play the radio via the phone and works without a hitch.It can connect 2 phones simultaneously, it tends to connect to the last connected device as soon as its turned on so just need to disconnect on device to use another.

The pack includes the Bluetooth device, short 3.5mm connector, longer 3.5mm cable, USB C charging cable and a manual.The device is very compact, around 2 inches in length with a multifunction centre button for turning on/off, pairing, pausing music and accepting a phone call, two buttons on the side for increasing and decreasing volume and holding either will skip songs forward and back, it does seem that the plus button skips backwards and the minus skips forward which is odd despite the plus increasing volume and the minus decreasing it.The device also has a microphone so it works for voice calls if the device is in a good position, in my car the Aux input is in front of the handbrake so it probably won't pick up my voice clearly.I used it today for around an hour driving around and it was great, sounded perfect through my car speakers and was easy to use the buttons on the device while driving.I can definitely recommend this for older cars that don't have Bluetooth built-in or a USB port on the stereo, previous I was just using a long Aux cable but when my phone is in the holder, the wire dangles and this makes it hands free. Plus when using maps, the voice assistant plays over the car speakers as well 🙂Happy with this product and hopefully the battery from full charge lasts a good while too(I'll update on exact usage time).

Great quality 3.5mm aux to Bluetooth converter. Used this several times now in my garage. I have an old sound system that only has a 3.5mm aux connection and wanted not to plug my phone in constantly. Sound quality is perfect and connectivity was seamless. I highly recommend this product.

Reviewing after owning the product for around 9 months. It always connects straight away, there are no problems with sound quality and it's made playing music from my phone incredibly easy. The battery life is great and doesn't drop much even if I don't use it for a couple of weeks. The only slight niggle is how long you have to hold the power button down to wake the device, but that's being very picky.Overall, fantastic quality, functionality, battery life and value for money!

Simply does not work. Numerous failed attempts in last few weeks - following the instructions thoroughly . Given up. Could it be that in the advert description it states 'stereos' as being compatible - but in fact they are not? For me - a waste of money, for which I am surprised, as I rate Ugreen products highly. Dissapointed

Works really well and connects as soon as I get into the car without having to manually switch on. Sound is great too. I am really pleased with this buy.

This product works well at it's core, but the battery life leaves a lot to be desired, and the voice messages are also quite annoying. If the battery is getting a bit low, it will repeatedly interrupt whatever you're listening to to tell you. This can be useful in some cases, but instead just means the usable time is further reduced. Even with an hour or more battery remaining, it will keep telling you 'battery low' every 20 seconds.Connection strength is fine, and it's compact and easy to connect to. But it is let down by the frustrating factors mentioned above.
