I have constant tinnitus, same reason for my hearing loss - loud noises at a younger age - guns, construction (heavy equipment, rock crushers), loud concerts, and finally chemotherapy and radiation for cancer. It has been a constant companion for about five years now. I have learned to ignore it with the help of music playing in the background at home or with ear buds while out walking or public transit, (I no longer drive).
I now have Costco ReSound Forte 8 (same as ReSound Linx 3D) and I find they help to attenuate my tinnitus while wearing them. When home I always have music playing, when out I still listen to music via Apple Air Pods that fit well with my RIC hearing aids, so I keep that constant sound distraction, giving me something good to concentrate on while ignoring the hiss in my head. Depending on what I am doing, my music choices are highly eclectic, classic rock, jazz, blues, classical, world, reggae, just no rap or hip-hop.
I occasionally use the ReSound Relief app that is meant to help with tinnitus. I don’t think it helps tinnitus directly, but the nature sounds of waves on the beach, forest sounds of birds and wind in trees, crackling fireplace, thunder storms do let me read and helps me ignore the hissing tinnitus. I have a few coffee shops in my town that have outdoor seating where I read for a couple hours, thanks to generally nice weather, even in winter.
For me, just accepting the fact that this hiss is there and always will be makes it easier, staying calm and not frustrated. On very rare occasions the tinnitus will keep me from falling asleep, so I have a tropical forest in the rain sound that I play on bedroom speakers at a very low volume. I concentrate on the rain and breath deeply, and am asleep very quickly.
tl;dr I do not find that ReSound HAs make tinnitus worse, and actually make it less noticeable when wearing them.
