Review on SIMOLIO 2 Pack of Wireless Car Headphones: Kid-Friendly Automotive IR Headsets with Travel Bag for Universal Rear Entertainment System by Enrique Espinoza

I bought these for my kids to use in our van. They look beautiful and are comfortable. The problem with them is that they lose a lot of tone. They show they're on, but just won't connect I think. There is no rhyme or reason as to why this is happening or when it will happen. They can safely be watching a movie and suddenly one of them has no sound. Not even both. It's very random. They even try changing channels to see if there's a difference, but it doesn't. Then they suddenly work just as irregularly as they left off.
