I found a pair of Auvio wireless headphones and found they won't work with my Classic III Plus box. They do work with my digital box though but....there is a slight delay and will probably just use them for around the house and teaching audio with the V3i. Now....does anyone know if an analog set would work with the Classic? I just did a trade to get this machine back in my hands and I just have no fundamental knowledge and sure as heck don't want to use trial and error with this. Once having the top quality V3i unit....wireless has spoiled me. (A small/tight set of "backpack" headphones would sure be nice....with delay and lesser build quality or not.)
