Harry asked: “My wife has 2 Bluetooth hearing aids. I have a fairly new 4K TV and a 4K receiver, but neither one has Bluetooth. So I bought a bluetooth transmitter that you can plug into the headphone jack. The problem is, it only works about 8 hours on a charge, then you have to plug it in and it doesn’t work while it’s charging. Is there a USB transmitter that i can use for the bluetooth hearing aids. It sure would help my wife who has profound deafness.”
Harry, there are bluetooth transmitters that are virtually the same as the one you have except that they work while they’re plugged in.
The TaoTronics Wireless Portable Transmitter sells for $28 and is one such transmitter.
The problem you’ll run into very quickly is that most bluetooth transmitters are chinese generics. We can’t really say “buy the Sony one” or “buy the Samsung one.”
We promise they do exist though, we know that because we use a chinese generic bluetooth transmitter on remote broadcasts to feed a speaker we use so that waiting guests and PR reps can listen live as we record interviews for the show. Our no-name generic works both on battery and A/C power.
Your best bet is to look at specs online and make sure they specifically mention that they work while charging.
Sorry we can’t give you specific models, Harry, but even the TaoTronics we mentioned earlier looks exactly like the one we use.
They really do look like they all come out of the same assembly line and just get stamped with different brands at the end.
