In the ear or behind-the-ear, that is the question

[Wonder Why]

9. IMHO, as a hearing aid user of many types since 2003, I consider the in-the-ear advantage to be primarily cosmetic

for those too embarrassed to be seen wearing hearing aids. The BTE ones have been far more reliable and less irritating because the part in the ear can be easily changed as compared to the in-the-ear type.

As to the TV communicator, you can get good ones for less than $50 that do audio to bluetooth. If your hearing aids support setting up multiple bluetooth pairing, there should be no problem. In fact many TVs now have built-in bluetooth and that means you need no external device. Look up your TV model and the word "bluetooth" on Google to check.
