Front Seat Use
Brand new member here and this thread caught my eye as I also just bought the Circuit City headphones.
I just wanted to comment about using them in the front seat. I was hoping that they would work in the driver's seat so I could listen at night when the rest of the family was sleeping. Turns out they are not real good for that. The signal broadcast via infrared (as opposed to a radio signal), so they are pretty much line-of-sight. I was able to get get reception from the driver's seat by tilting my head just right, but that wouldn't work while trying to drive. It was probably pickup up some kind of reflected signal anyway. With the RSA on, you can see the infrared beams on in the lower portion of the screen.
Just thought this might help some out there make better decisions.
BTW, it works great for our kids, they can listen to something totally different than what we have on.
Great board here too, very regular reader.
Later!
