A:AnswerIt’s an adapter cable that mirrors your iPhone onto whatever you plug it into like your tv or a monitor. So if you are watching Pureflix on your iPhone and plug it into your tv it will display whatever you see on your phone to your tv. Whether it’s a streaming app or playing a game or surfing the web or social media. You might be thinking of a product like Roku which has streaming apps that include Pureflix. Hope that helps.
A:AnswerYour device must have a Lightning connector. This adapter will pass audio to TV monitor.
If you have a dedicated headphone jack or Bluetooth, ear buds should work.
A:AnswerI use it with the iPhone 11 Plus to watch Netflix and others. It works very well and better than expected. I have not used it with FaceTime but it should work fine as it mirrors your phone on your tv. I am not sure at this time what aspect ratio you will get on FaceTime.
