hmmm so I am not sure I understand what u mean here. I plan on using these for just my big screen tv so as not to bother my kids while they are doing homework. I will sit in my chair about 10 feet away and do not really care about being able to walk around the whole house, in other words, they can work as line of sight and I am happy, so IR would work fine if the quality is decent. I hear RF can have hissing and what not if there computers, phones etc, around. Also, do I plug these headphones in the Line Out jacks of the TV or the Line Out ( Var Audio) jacks ?? THanks
