Looking for TV system for elderly parents

If it is the Beam you want to use, it can be used without surrounds and have all the audio come from the front. There is also the Speech Enhancement feature that you can activate inside the app that will boost dialogue. 

They need the rear speakers to operate as the main dialogue speakers, the beam at the front would mainly be the key to connecting the TV to the sound system since it makes it really easy , using the TV remote as the main sound adjustment. They aren't very tech savvy ! I'm assuming just using the One's ( or newer version ) wouldn't work alone without having to use Bluetooth and fussing with that everytime they go to watch TV ? They need to ideally just use the remote as usual, with everything hooked up and ready to go ! 

You could do it with an Amp, connected to a set of third-party speakers. But, configuring the Amp would mean setting it up as the “main” speakers and then locating them beside the viewers’ seated positions.

Even so I wouldn’t recommend it  First the Amp needs setting up on their wifi (do they have that?). Then there’s the risk of anything going wrong. They don’t need a multi-room system. Surely a “conventional” system may be the lower-tech but better solution here?

And the Amp would be ‘behind’ the sound bar (Beam) by 75 ms.

Unfortunately, there is no great solution made by Sonos for the hard of hearing. No way of synchronously hearing the voice channel out of ‘other’ speakers. 

I was thinking of Amp as front channel, but with speakers by the seats; no Beam in the configuration. But I still think it’s not a great solution in this use case. 

If the Amp is connected via HDMI ARC, it is still considered a ‘Home Theater room’, so any grouped room would still be delayed by 75ms. 

But yea, you could instead connect the Amp via the analog line in and skip that issue…but the voice sync with the video would be an issue, as you’re paying the 75ms on the analog input, instead of between the two ‘rooms’ 

But, I agree, in your configuration, moving the ‘fronts’ to by the seated person, and no ‘grouped’ rooms, that would work. 

Ace headphones would be excellent for this situation...except you can only use one at a time, and you can’t have audio go through the headphones and soundbar at the same time.

My Mom needed a solution to that problem when she moved into an independent living apartment and I settled on a wireless portable TV speaker. We bought a Simolio model, but there are quite a few options on Amazon. It lacks the “gee whiz” factor of finessing a solution with Sonos speakers, but it’s simple and inexpensive. And also not prone to going batty when executives decide to rush out ill-planned software updates.

I agree with the others, if you want Sonos, the best setup would be the Amp connected to the TV with HDMI-ARC and to have CEC enabled (to use the TV remote) and a pair of passive speakers from any other brand connected to the Amp with speaker wires. The speakers could be in-wall, in-ceiling, bookshelf, floor standing, etc.
