Having severe hearing loss, i must have the TV volume very loud to hear most of the words spoken

I now wear high-end within-the-ear hearing aids to correct a severe hearing loss and the Sennheiser SET840-S wireless system is designed to transmit a wireless radio signal from the sending unit connected to a TV, Home Theater System, or audio playback system directly to Telicoil equiped hearing aids.

I bought this for my husband who has a slight hearing loss

With my approximate 90+% mid- and upper-frequency hearing loss I am definitely at the upper end of what the Sennheiser SET840-S is capable of doing for my hearing loss, but in fairness to this fine product I have to say that I believe the sound volume of my within-the-ear hearing aids is rather limited and that the far higher sound amplification provided by external behind-the-ear hearing aids would very likely overcome the limitation some might have with in-the-ear hearing aids.

UPDATE (December 2013): After nine months of use, everything works just as perfectly as it did on day one
