If you have a Costco within a reasonable distance I would suggest you go there. Their current Kirkland Signature model is the KS9. It does Bluetooth with either an iPhone or Android. These are premium level hearing aids nearly identical to the Phonak Marvel for $1500 a pair. I would suggest trying these before spending 2, 3, or 4 times more to get something that is no better or worse.
I have the KS8’s along with an iPhone. The hearing aids prompted me to get the iPhone, as I was (am) a smart phone hater. But the reality is that the phone makes the hearing aids more functional. I could certainly do without the smart phone if I had to though. Bluetooth is essentially ubiquitous in hearing aids today, and one should not have to pay extra for it. The real cost is the cost of the phone plan. It is nice to talk on the phone with the audio coming directly to your ears while the microphones on the HA are somewhat muted.
I do not use any supplementary devices or Bluetooth to watch TV. I find if anything I have to turn the TV down to listen to it.
Hope that helps some,
