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.

HIGHLY recommend.I've been looking for an adapter for 5 years for my BMW that didn't require me pushing a button every time I got in the car. The AUX port and USB port are both located underneath the armrest, so every time I got in the car I had to pull it up and click. No more. This little thing is incredible and sounds amazing. There's no battery to charge so all you have to do is start your car and go. Connection is automatic.

I used the product in my older 2010 CR-V with an aux cord over a radio reciever because I figured the aux would be much more reliable. This is the product I chose, and I wasn't disappointed. Even though there is some very light static sound (to be expected for the price), it's barely audible even when nothing is playing. I had it out of the box and operating within five minutes and never lost connection until the car turned off and power to my cigarette lighter was killed. The only reason why I gave it four stars instead of five is it would get super hot on summer days (like almost burning) even in the shade, but it never affected playback quality once.

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!

This is the best USB out of three of the adapters. I tried the sound quality is better than thre three other Adapters that I’ve tried very easy to use does not run on batteries works very well and the music playback is consistent

Product works great! Streamlined auto-connect is super fast, and the sound quality is very good considering the price. highly recommend if you are looking for an affordable bluetooth adapter.

Connectivity was fast and very responsive. Took all of 10 seconds to install. Very small and compact in the center console which I like. Sound is pretty amazing. 5/5 stars.
