1Mii Bluetooth 5.3 Car Speaker, Handsfree Bluetooth Speakerphone for Cell Phone, Motion Auto On, Support Voice Assistant for Android and iOS, Wireless Audio Car Kit with Visor Clip

My car's head unit allegedly supports bluetooth, but doesn't work properly. I purchased this Mii bluetooth car speaker as a work-around. I like it! It pairs easily and the sound on both sides of a phone call is clear and crisp. I doubt music will sound nearly as good as my car's built-in stereo; that would be a tall order for a $40 product with two small speakers. No big deal. USB-C charging is a big win: there's no chance of ruining the USB-C connector by plugging in the cable upside down. Battery life is good. I've been turning this speaker on when I get in the car and off when I get out to extend the battery life. After re-reading the product description, I see that it will auto power on when you get in the car. I'll have to give that a try.

This is a game changer. I have an older car. So this is so helpful. Automatically connects when my phone is near. Sound is great! Works so good.

I'm impressed with this Bluetooth Speakerphone. 1. It lasts weeks on a charge (for me at least.) 2. People can hear and understand me. 3. It's usually loud enough (except when all my windows are down.) 4. It uses a USB-C charger, just like my phone and other devices which makes charging simple. 5. The buttons probably make sense, but I almost never need to use them. 6. It turns on when you open/close your doors. And it will turn off if no connection is made. 7. The clip for the visor is a nice, wide, metal clip. It's better than some expensive models. 8. The volume level knob syncs with the Bluetooth volume level. It sort of works a bit too well sometimes. If you get out of your car and are still in close proximity, it will stay linked. So if you answer a call shortly after getting out, you might be confused as to why you can't hear the people on the other end of the call. Every so often, I'm wondering if my phone is broken, but nope, it's just me being clueless.

The sound is awesome. Very clear & easy to use. The only negative I’ve got to say is that if I don’t turn it off before coming in the house it stays connected. I bought a second one for the other car

Extremely disappointed. Many people had difficulty hearing me. I had trouble hearing them. I had to return it. I was optimistic, until everyone started saying they couldn't hear me or couldn't understand me. Was only a couple days of attempted usage I quickly went back to just using the phone by itself. I will give another brand a try. Disappointed. I've got two layers of Dynamat on the floorpan of my car and two layers of Dynamat in each door. I also have six coats of undercoating on the bottom of the car. The difficulty of hearing should not have happened at all.

This works great once your connection is in place. Speaker and microphone work well and callers report that they can hear me fine above the road noise. The main drawbacks for me is the Bluetooth connection. Does not always connect automatically when I enter the vehicle, and often stays connected when I am parked in the garage, so I need to manually disconnect when at home.

This worked perfectly. I don't have an internal microphone in my car so I needed something to connect my phone. Had no problems using this. The sound was great. Definitely recommend it. It's worth the money.

This device will connect to your phone when it feels like it, whether you want it to or not. When you enter the vehicle it may take up to 5 minutes before the phone pairs automatically, or if at all, with the device. You can be out of the vehicle and have manually disconnected from the device, but if you are within range of the Bluetooth it will automatically reconnect, even after a long period of time having elapsed, without notifying you that it is connected. Sound quality is at best adequate. Unit does have a long battery life but that is about the only advantage of this device.
