I was given a Roger Select iN to trial a couple of weeks ago. It has an adapter that will plug it into a phone jack on the back of the TV. With that, I use the myPhonak app to adjust the volume I’m hearing from the Select against the volume my spouse has set from the TV itself.
I find that the streamed sound is an augmentation to the regular TV sound, but not a replacement. On the other hand, I’m not noticing any difference in sound-arrival times. It all sounds like whatever the TV is supplying, only I’m hearing some augmentation. When I mute the TV, I still get my feed. It’s just softer.
Were we more up to date, I gather that I could use some kind of fancy optical thingie to get TV sound to my Select. In theory, it might be a fuller sound. It appears to me that the phone jack thingie I have doesn’t do stereo, although I think it should. Perhaps the Select precludes that. The Phonak rep says she’ll send me an adapter that takes sound from RCA connectors, which in theory should then supply a fuller sound. We’ll know in about a week, just before I have to pony up the big bucks, which might mean I’ll have to adjust my wine budget to cover things.
Of course, I’m not considering the Select as an expensive TV streamer. That’s just something else it can do when it’s not needed for focusing in on speech in noisy places.
