Sennheiser Set 840 S Wireless Stereo TV Headphones - Premium Wireless Audio for TV Watching, Gaming & Movies - Comfortable Over-Ear Design with Long Battery Life

I bought this Sennheiser SET840s system hoping that it could do at least one of two things well: (1) enable me to hear spoken words on television through my own headphones clearly and at a much lower TV speaker volume than I have been using; and/or (2) transmit clear spoken words directly to the tele-coils in my Bernafon Veras 9CP hearing aids.The jury is still out on number 2, above, because I will have to have my hearing aids set up differently by my audiologist for them to work with the Sennheiser system. But number 1, above, is such a rousing success that I can already rate this product with five stars even if it turns out they can't work directly with my hearing aids at all.The manual is well written and set up was easy. Even used with just a five-dollar pair of Panasonic headphones, the Sennheiser system worked great: clear, clean audio with no static and no dropouts--none at all. Just clear sound with plenty of volume to spare, even with our TV set to half of the volume that we've been used to using, or no speaker volume at all. I no longer have any difficulty understanding all the words spoken in movies, even when the actors are whispering like Bruce Willis so often does. And music comes through beautifully in full stereo. My wife is loving this system because I no longer ask her to tell me what someone just said--never. Sometimes she asks me that. And the audio is just as clear three rooms away inside my home and 70-80 feet or so down the driveway outside.The manual describes several methods for connecting the system to your TV set with 3.5mm (1/8"), RCA or external microphone connections. We have have a 55" Visio TV with a 3.5mm audio out jack that works perfectly with this Sennheiser system.I will update this review in future to report on longevity and any problems that develop. And I'll also report on whether my hearing aids, once they are reset, work directly with this system. However, as long as the system continues to work so well with my own headphones, it will keep its five-star rating from me regardless of whether it ever works directly with my hearing aids.UPDATE (December 2013): After nine months of use, everything works just as perfectly as it did on day one. I have since learned that my hearing aids cannot be set up with a manual t-coil switch, so I could not get them to work with my Sennheiser system . . . UNTIL I mounted two small pieces of magnetic tape on my glasses right against where my hearing aids are. THAT activated the t-coils in my aids and--presto--with my Sennheiser system I could hear the TV directly into my hearing aids with no headphones necessary. The t-coil sound is clean and clear, but it is not in stereo as the Sennheiser system is with headphones, so movie music doesn't sound nearly as good. But I hear the dialogue loud and clear either way. I generally use the headphones when it's just the two of us watching a movie. But when family and friends come over to watch sports, a movie or whatever, I generally use the t-coil system so I'm not sitting there with headphones on all night. This Sennheiser system is one of the very best purchases I've EVER made -- and I'm 69.
