The ReSound Multi Mic does not do what it says on the box!! I'm high frequency deaf in both ears and rely on my i-Fit CS71W hearing aids to hear. I use an EchoLink Wireless TV system to listen to the TV. I like many others with hearing difficulties, struggle to understand speech in crowded places. I bought the Multi mic as it said that it can be placed on a table to pick up multiple speakers - It does! Everyone including yourself! I hoped it could be pointed to the people you were with and hear them and not everyone else. I found that it picked up my own voice, with loud side tone and people in all directions, making it worse than just having my hearing aids. The table microphone is not discrete enough and maybe the wearer mic is still active and picks up too much background... I have tried it with the TV and placed it by the speakers and it was sort of okay, but was 'tinny'. I have tried it with the line in mode, but there is no tone control, so the sound was not that great. I have tried it outside when I'm working and trying to listen to the radio - It helps, but 25m line of sight is very optimistic. If you turn round away from the mic it quite often cuts out. I have used it to listen on my computer, as apposed to headphones, which is good, as I don't have to remove my hearing aids to listen. - But paying over £400 (nearly as much as the computer) is a very expensive way to listen!! I have not used the single speaker mode (my wife was not that enthusiastic to wear it). I'm not sure if you were attending a lecture, if the person turned round away from you, whether you would get cut off... I am going to see my hearing specialist tomorrow, who recommended this product to see if they can help. I'm very disappointed with this portable audio streamer. When I'm out, I have to rely on my wife to relay what people are saying and this is quite socially excluding and makes her cross!!
