I think I've got her on the right track. She DOES in fact have a HTIB and it DOES have a headphone jack. I told her to grab a pair of headphones and make sure that the speakers and headphones are working at the same time. Then to just order some wireless headphones with their own volume jack so that she can turn it up or down a little independently from the main speakers. I haven't heard back on her test or purchase. She likes the over the ear ones better as I found out when I too saw the woot today.
