I’ll throw my ears into this ring and perhaps represent the high-end option. For several years, I have been using a Williams Sound FM systemwith my home televisions. These PPA systems are not cheap by any comparison, but they are the system of choice for most churches, and many other theater/auditorium venues.
There are a few things I like about the WS PPA system that put them above all the rest in my world.
1.) The belt clip reciever is super easy and very handy for instant volume control (am I the only one who hates the high volume commercials?) WHen I watch TV, I wear a single earbud from the WS receiver (it can handle duals but is not stereo), and sit with the receiver either in my hand or pushed between the seat cushions so I can keep a finger on the volum wheel at all times. My ears will accomodate my open fit hearing aids AND an earbud at the same time, so I get the TV sound, and have the advantage of hearing aids for all other voices or noises around the house.
2.) The receivers use AA batteries that seem to last quite a while. I only watch TV maybe a couple hours per day, and it takes at least a month for me to run through a pair of AA batteries. No need to return the receiver to a charging base, or worry that if I watch too many movies in a single day that it will run down.
3.) My receivers are multi-channel receivers, so I can take my own receiver to church, or to a funeral or wedding, or the performing arts theater and tune right into their system for easy listening without having to adjust my hearing aids.
4.) With up to 1000 foot range, there’s nowhere in my house that can hide from the signal!
5.) With an inexpensive audio adapter cord (that came with my Seimens tek remote) I can plug the receiver directly into my tek or mini-tek to stream the TV audio directly to my hearing aids (although I actually prefer to use a bud(s) for the TV for richer sound quality). They also accept full headphones or any earbud set with a 3.5mm jack (watch Game of Thrones or Band of Brothers with full coverage headphones!! WOW!! )
6.) There’s also a Tele-coil neckloop for the receiver that will work with hearing aids that are TC equipped, so no buds required. I haven’t tried a neckloop with my Semiens aids because the telecoil amp is actually in the remote, not the aids, so it’s easier to just plug directly in.
My Semiens aids have blue tooth streaming, so I could do without the WS system entirely, except that the audio sound from the BT system sucks and there’s virtually no volume control that’s handy and instant. I was using the WS system before I ever got hearing aids, and have found that it is still a superior system than what my hearing aids can provide. My WS system cost around $550 which is a small fraction of what my hearing aids cost!! I actually purchased a second transmitter for the bedroom TV so I can have the same setup at both places. Pricey, yes, but worth every penny!
If I couldn’t have my WS, that Sennheiser SET840-S system looks like the closest second choice.
