I have them, but mostly for my hearing loss. I originally bought the Phonak Audeo Smart early last year and shortly afterwards they released the Audeo Q. Since mine didn't have the noise generators I upgraded to the Q a couple months back.
For my hearing loss I love them. Regarding the tinny sound someone mentioned, I had that in the beginning but over a few months and some adjustments it went away. Now, sounds without them in just sound weird because my brain has adjusted to the new high frequencies I am now getting more of.
If you are only getting them for masking, I would try the Widex Zen aids. I have never tried those, but I think they offer more masking features like music and soothing sounds rather than just plain white/pink noise.
I did have my audiologist set mine up so I can turn the noise generators on/off by switching into that program manually. Then I have a Phonak ComPilot that gives me the ability to adjust the volume of the noise. So on really bad T days where I am in a quiet environment, I can turn up the noise. But I rarely do that though. 90% of the day I hardly notice the noise generators on, but when I am in a quiet place it helps give me something else to focus on. It's slowly getting to the point where I don't even need it though.
