I just recently purchased the Sennheiser Rs130's, the i-doser approved headphones, and I have a question to all those wireless headphone users out there. How do I get my headphones to focus onto an audio signal without having to plug the transmitter in? The auto-tune function never focuses in on the signal, so which part, the headphones or the transmitter, receives the audio signals? And how would I get my headphones to pick up an audio signal? I've done it before, but now its just not working anymore. Should the television be on or off? Should it be at high volume or low? How far away should the television be from my headphones when I auto-tune?

wait, wait wait....
you're using your tv for i-doser?
i sense something wrong :S

What I meant to say is, that the closest outlet I have to my computer is the one by my television, and I want to know how I would be able to auto-tune onto my computer. Hence, would the tv have to be off/on, what volume would I need it to be at, and how far away should the transmitter be from my television or computer?
