Ihave two hearing aids and use a sound bar and sub-titles on my Living room tv, Still struggle with sound at times.
My very cheap (non-smart) bedroom tv I use with headphones. These are wired into the tv, but come off the charger device and I use wirless. These have the volume control on them and give me total clarity.
Seriously considering getting a further set for my Living room tv.
