Myredracer,
I also have Phonak hearing aids (Audeo B90)and the TV connector via bluetooth. It is amazing how well you can hear the TV using that device. Also, the wife can mute the TV during a phone call, or listen to it at her comfort level without affecting my listening at all.
The only drawback to it would be that you have to wear that necklace around your neck. I just tuck it under my shirt. I would urge you to try it out since you already have it and am pretty sure you will come back here and thank me. :B
