Another option to consider (I’m assuming this is compatible with Jabras, as with ReSound aids, and it likely is) is a ReSound Micro Mic or ReSound Multi Mic. Turn it on and place it near the TV speakers. You can leave it turned on and connected to a charger at all times. The disadvantage to it is that it will pick up ambient room noise too, though this is not a major problem in many relatively quiet locations, as the TV dialogue is easy to follow even with a little ambient noise. As with the TV streamer, you only hear the transmitted sound from the mic in your aids when you select it, not all the time.
A mic tends to be cheaper than a TV streamer, especially when purchased on eBay. You can also move the mic around to different TV sets in the house if needed or take it out to, say, doctor’s appointments or meetings. If you use the smartphone app, as with a TV streamer, you use Bluetooth and can program the mic to work with your aids without an audiologist. You select it in the smartphone app when needed as you would the All-Around program, Restaurant program or a TV streamer. Your smartphone app can switch to send sound directly into your hearing aids from among one, two, or three devices including mics and TV streamers, and you can control playback volume from either the device itself, the smartphone app, or both to get the sound level needed.
I’ve used a ReSound mic rather than replace one of my ReSound TV streamers that died. (Note that TV streamers and mics bought on eBay can be hit or miss in my experience, as they’re often used or refurbs, but as you suggest, the substantial savings can make a roll of the dice worthwhile.)
