Bluetooth 5.4 Car Adapter, Hands-Free Call & Noise Cancelling AUX to Bluetooth Adapter for Car, 3.5mm Audio Blue-Tooth Receiver for Cars Stereo Home Speaker - 15H Battery Life

This car adapter works well in older vehicles that do not connectors for cellphones. Cable is provided to plug into the AUX for the car radio and a Type C connector for cellphone. The sound is very good and can use as hand-free device for phone calls. No ambient noise on calls and clear sound for listening to music, podcasts, audio books, etc. Good product.

Easy to use. No protruding buttons (to mess with your music while the receiver is in your pocket). Pairs easily. Good sound quality.

Have never had a problem with trying to get it to connect. Still works when charging, and is always in my car. Sound quality and noise levels are great. I don't normally call when in the car, bit I've noticed that my phone will default to the UGREEN microphone, which is annoying. Not great for calls, but it's great for normal music functions.

I finally have Bluetooth in my 2014 Mazda CX-5! I just wanted to be able to play audiobooks and music from my phone without having to connect a thousand cables first, and for that this thing is spot on. Pairing this adapter with my Moto Stylus 5G (with Android 12) was easy, and now it automatically connects every time I get in my car. I also had no trouble connecting the adapter to the car itself; the center console storage ... box?... thingy?... has the aux port - a standard headphone jack - and a usb port, so I just leave the thing plugged in in my center console all the time. I have not tried making a call with it nor have I done anything else with the microphone so I can't rate those features yet. However, for being able to play audiobooks and music from my phone via Bluetooth, this does exactly what I wanted. And, fwiw, I have not noticed any sound distortion with spoken word or music (although the stock radio in the Mazda isn't great to begin with, so who knows). My only beef with this adapter is that you can't turn it off. This is annoying and potentially problematic. For one, the range is really high and I keep finding that it remains connected to my phone even once I'm inside and upstairs, with my audiobook or podcast playing without me realizing it. Sure I could unplug the USB cable, but the battery holds a charge for a few hours so that doesn't solve the problem. Plus, I don't want to have to fiddle with cables the next time I get into my car. My biggest concern, however, is that if it's always on, then it's always pulling a little bit from the car battery even when the car is turned off. I doubt that the draw is enough to significantly impact the battery in the short term, but what if I go out of town for a few weeks and forget to unplug the adapter from the car before I go? That said, I'm still happy with this little adapter. It does exactly what I wanted it to do, it was very easy to set up, and it doesn't negatively impact audio quality, at least for me. I just wish I could turn it off.

Works very well. Haven't had any issues. Connected quickly and easily to my Android. I don't use it for calls as people have told me it's not great on the receiving end to hear me.

Works great, easy to pair, has great range, and sounds great! Stays charged for a VERY long time (many hours). I don't know just how many, because I haven't run it completely out yet. I use it for parties where we need music running, so I've run it for 4-5 hours straight with no problems. Hooked up to an amplifier, and there wasn't any connection noise, etc. — just great sounding music!

Unfortunately I was pretty disappointed in this little bluetooth adapter. While the device works, appears built well, and has no connection issues, the audio quality from the internal DAC is pretty poor. There is a distinct lack of highs and the bass is very muddy. There is a small amount of audible hum when your speakers also at high volume levels and no music is playing, although it is less than other devices I've tried. On the positive side it's very compact, and is very reasonably priced. The latency is decent, and the included cables and 3.5mm extension are nice. I'm just disappointed in the audio quality. If played on poor speakers you might not notice, but in my car I absolutely noticed. I'm giving 3 stars because the device does work, and I should have no expected so much from such a cheap device, but here we are anyways.

Works well, sound and signal is clear. Easy to connect to my iPhone. You can charge it in your car while using it
