Hi Jk. Group settings are hard I use my tcoil In my heating aid even there is no loop setting . It helps a little bit. There are devices that you have a mike to a mini box type thing like pocket talker. Having folks in a circle settting helps. There a new thing I am made aware of by my friend a designer writer.. way you set up your home and what type of furniture you have makes a difference in sound. Softer furniture is. Wetter than having wood type .
