Excellent product
Title: Easy to Use and Works Great I’m very happy with this Bluetooth adapter. It was easy to install and connect, and the connection has been stable and reliable. It works great for streaming music and connecting Bluetooth devices to my car. The compact design is convenient and doesn’t take up much space. Overall, a great little adapter that does exactly what I needed.

Love that it automatically connects
I got frustrated with my old one in my truck because it didn't auto connect and the connection point was above the glove box so it was quite a stretch. My sister recommended this one and it works great. If you don't drive much or very far for work you may have to bring it inside occasionally to fully charge it or leave a charging cable constantly connected to it.

These work really well.
These work really well. Our family has two of them. One is in my daughter's truck and allows her to connect her cell phone to an older radio. The other we use at our church to play music through the sound board remotely. The battery life is good and the sound quality is solid. I ended up using a mono adapter to connect it to the sound board. This seems to work better than a stereo adapter in that application. The ability to connect two devices is a nice feature.

It Works! And Sounds Fine
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.

Very quiet
It works well and has good battery life. It has a few annoying quirks that kill it for me though. When you plug it in it automatically powers on and connects to things. Also the volume is very low compared to similar products I have purchased. It is too quiet to hear over the background noise of the train with my koss portapros

One of my new favorite things
I found this gadget pretty intuitive. When I got it I plugged it into the aux port of my old Bosch boombox/charger. It's not a loud box. At first I was getting tiny sound, like a whisper. But over the years I've learned what a crap shoot these 1.5mm jacks are. So I fiddled around with it. The sweet spot for me was pushed in and backed out about 1/4 inch . Since the unit sits on the floor I have only had to re-adjust the jack position once in about 6 hrs of use. After adjustment, the sound was loud. I was not listening to music, so I can't say anything about the stereo properties of the jack in this hybrid position. I haven't charged it yet. It's nice that when it hooks to my Moto G 2022 it shows me the battery charge level. Still showing about 50% after 4-6 hrs of use. Some reviewers said there's no way to turn it off??? 🤯 I suppose I have had some similar interactions with Bluetooth stuff over the years. I instinctively just held the power button a few seconds and it came on. When I was finished, I held the power button a few seconds and it went off. It is of course, important to power off the device between uses to prevent battery draining. EZPZ. Would definitely buy it again.

Works as specified. Sounds a little better than wired connection. Recommended.
It works as specified. Connection and pairing bluetooth between my iPhone and an old Panasonic mini-Hifi set went without any glitches (so far). I find the sound quality quite good as compared to a wired connection from my phone to the hifi audio port. The song continued to play when I bring the phone 3 - 4 metres away and behind a wall. The item was made in China. I do not know how long it will last, but so far so good. Item was delivered the next day after ordering and payment.

Exatamente produto!
Incrível! Funciona perfeitamente bem no meu carro que não tem Bluetooth, encaixo na entrada p2 e pronto, só conectar no Bluetooth do celular. A bateria dura muito, fica até mês sem carregar e eu uso todos os dias. Vale super a pena!
