Oticon TV Adapter 3.0 Problem with shrillness

My aids are Oticon OPN 1. They work well. But when I connect them to my TV Adapter 3.0, with TOS, the voices are outrageously shrill. At first I thought, “Wow, this is great.” An hour later, I wanted the speakers (and music) to lower their voices. Not a lower volume… a lower shrillness. Is there some way to adjust this? Thanks for any suggestions.

Yes, there are many adjustment settings;
Oticon Opn Phone/TV Adapter/ConnectClip sound settings for quality/bass/mic

Oh, you may be specifically interested in the TV Tab settings of;
Sound Quality = Fuller, not Brighter
and
Power Bass = off, low, mid, or high amount of bass
