Review on HDMI Adapter for iPhone to TV Projector Monitor - 1080P Digital AV Connector for iPhone 12/11/XR,X,8,7 & iPad-White (No App Required, Power Supply Support, All iOS Compatible) by Justin Early

I liked it for the first few weeks, but then I discovered a few things that made me turn it off and only use it to listen to music on my iPhone through my car speakers . If that's all you need, then this works great. Sounds great and is very easy to use. However bad. It adds hiss and hiss to all your FM stations. The only way to solve it is to turn it off. It will work for making hands-free calls, but I've had many complaints from people I speak to that the audio they hear is terrible. Ideal for listening to iPhone music through car speakers. Nothing more. Update: The company contacted me and sent me another device to test. I believe this is their new version. For that you need to give them +. However, the new block worked much the same as the previous block. However, the new device has a feature that allows you to easily turn it on and off. So when I'm listening to the radio, I no longer have to disconnect the device from the power supply, I just switch it off. Unfortunately, hands-free calling is still not acceptable. When I call someone they ask me to only use the phone because then they can't understand me if I use the device. I did a little experiment and found that it had to do with how far away you are from the device. If you approach the device directly and speak directly into it, the sound at the other end is okay. Not great but okay. However, when I sit upright and drive, I'm too far from the mic and it doesn't work for my car. Conclusion: if your computer allows you to get close to the device (microphone) it might work for you, but in my case it doesn't work. I think you need to be closer than 1.5 feet to be able to get even acceptable audio for the people you are speaking to. If possible then this is a really good unit.
