UGREEN Aux to Bluetooth 5.4 Adapter 3.5mm Bluetooth Receiver for Car USB 2.0 to 3.5mm Jack Kit with Built-in Microphone Aux Input for Hands-Free Calls Compatible with Car Speaker and Home Audio

Paired phone on first try. Application: pair of powered stereo speakers, with 3.5mm audio aux input jack. Insert 3.5mm plug in speaker aux jack. Plug USB cable into USB / 110v ac adapter plug. Then insert adapter plug in to household ac outlet.Finally pair phone with Bluetooth device connected speakers. Voila! Now I can send music wirelessly from the phone's music library to the speakers. Sound quality is clear, with good fidelity, and no loss of volume, and I am picky.Why did take me so long to think of this solution? 5/5.

I wanted a Bluetooth receiver so I could wirelessly connect Spotify to my 2009 Civic. Almost every other similar Bluetooth receiver I could find is battery powered, so you would need to manually turn it on and off. Since this product is not battery powered, it turns on when it receives power, and off when it doesn't. This makes it perfect for your car and is exactly what I needed. It remembers your phone so you only need to pair it once, and since the receiver is built into the USB male head itself, it is very under the radar and out of the way. Also seems like it is made out of durable, high quality materials, so I am expecting it will last a decent while. Got mine for 10 bucks, and I am very satisfied.

Update (10/30/2023): Samsung to the rescue!So I recently discovered that my Galaxy S20 has a routines feature where you can program the phone to automatically do certain tasks when certain conditions are met. So in this case I was able to use that to automatically play music on Spotify when my phone connects to this bluetooth device. So that basically solved the biggest gripe I had with this product. Even though it was my phone that fixed the issue and not the manufacturer of the device, I am still going to update this review to 5 stars because now I basically have no issues with it. Anyways, feel free to read the original review below.I love this thing! So much better than the previous two bluetooth adapters that I had in my car. I used to have a battery powered aux adapter and a cigarette lighter port powered FM radio adapter. The battery powered one sounded good but was so inconvenient because the battery would constantly die on me during car rides. I could keep it plugged in but then I'd have a cable dangling down from it which was annoying. Also because it had a battery, it was bigger and bulkier than it needed to be, which cluttered up my dashboard for no good reason. The FM adapter was a bit more convenient (no wires!) but it sounded terrible. The sound was tinny and full of static. Almost unusable because of that. And because my car's cigarette lighter is always powered on, even when the car is off, I had to unplug it and plug it back in every-time I used it or else risk killing my car battery. Not a big deal, but annoying enough that it caused me to rarely used it.This one solves basically every problem that my previous two adapters had. For one, it's powered by USB, so I don't have to worry about any batteries dying. Plus, I can power it by plugging it in to my car stereo's USB port which does power on and off with the car, so I don't have worry about plugging in and unplugging every time I get in and out of the car. Also, it has the form factor of basically just a cable, so it take up almost zero room on my dash. Super sleek and discrete!On top of that it connects to the stereo with an aux connection so it sounds fantastic and doesn't have any of that FM radio static. I even noticed that I don't have to crank up the volume on the stereo like I had to with my previous aux adapter. I guess since it was battery powered, it needed to cut back on the output to save battery life.There's one problem with this thing though, something that I feel is big enough to warrant taking off one star. The thing is that this doesn't have any buttons on it. No play, pause, fast forward, rewind, or anything like that. Understandable since it's so small and sleek that there wouldn't be any space on it for that. That's fine. They would have had to make it bigger to fit buttons on it, so I think that was a good call to not include buttons. BUT... one thing that would have made living without buttons so much easier is if it had auto play. It would have allowed me to hop in my car, the adapter would power on with my stereo that's powered on with the engine, the adapter would automatically connect, and the music would play on it's own without any user input. I wouldn't even have to think about it, it would just work.It does have auto-connect which is great, but no auto-play. Meaning I have to pull my phone out of my pocket, open the Spotify app, and hit play. Not a huge deal, but it's the one thing that stops this from being a truly hassle free experience where I don't have to fiddle around with anything to get music from my phone to my car stereo. If they changed that, this would easily be a five star product for me!

Love this product. It's exactly what I needed for my 2010 Cadillac CTS Wagon. Only minor issue is my vehicle is on air suspension. When the compressors are on, this product boosts the volume a couple notches(the radio doesn't have speed-compensated volume, that I know of or can find). Then when the compressors fill the tank, the volume goes back to where I have it set. Also this thing still receives signal when the car is off, which is odd too(Cadillacs have constant power to usb at all times too). But none the less, it lets me connect my phone to the car.

Amazing Bluetooth connectivity clean clear crisp voice no static super easy to connect and has a microphone for voice calls if you need a simple but effective way to make your car stereo Bluetooth enabled this is it get it honest review

Super easy to use - just needs usb power on one end, plug into the aux jack with the other, then sync your device via Bluetooth. Works very well with very little audio delay due to the BT 5.4 standard.

Works better than many of the built in bluetooth devices that I have had in some cars. It seamlessly connects when I get in and turn on my vehicle. It has never dropped out on me once and I have used it for many months. Really the best value I have ever gotten from a $10 purchase.

Love this!!! So easy to use, bought 2 my husband and I use it everyday. We’ve gotten a few different types in the past but not anymore cause we’ve finally found the perfect one.
