While they’re nice tones, I wouldn’t buy them just for masking tinnitus.
Hearing aids are expensive yes, but I’d only buy them to be hearing aids. The masking is a nice bonus feature.
Most research has found almost any sound can be an effective tinnitus masker. A lot of people that are bothered by tinnitus also have anxiety disorders and the calming tones are likely helping in other ways, like helping those people relax.
I fit hearing aids all day. Very rarely use the masker settings.
