I've been using mine for many years, in fact I have two sets one for main TV and the other for late viewing in bedroom. I had thought I'd see if there may be better available but now I see that other reviewers consider sound quality is very good so I'll stick with what I have. They are very good for the stereo effect when watching TV and sometimes I can even understand what Emily Proctor is saying on CSI Miami. I'm a bit deaf, but with these I hear background effects such as barking dogs which helps realism. I feel that more people, especially the deaf, should be made aware of the advantages. I fixed up an elderly deaf lady with a set, she lives alone on a mobile home park, now her neighbours are able to sit with their windows open in the summer without having to hear the deaf lady's TV, she can listen to the TV news with her back to the picture while doing the washing up, everyone's happy. Perhaps the manufacturers should consider making sets with two sets of headphones linked to the one transmitter; it is not unusual to have two deaf people living together in a block of flats, or similar, where the neighbours would probably appreciate a bit of quiet. Of course one important aspect is whether or not plugging the headphone 'transmitter' into the TV automatically mutes the loudspeakers. Unfortunately few TV manufacturers include this information in the specs but of course it is of vital importance if there is more than one viewer, but only one needing the headphones.
