I believe I'm talking about the Sony CRE-C10 Over the Counter Hearing Aids. I heard about them from an article right before they hit the market They're like $1,200 I think, but they're effectively just Bluetooth hearing aids. They don't have any particular qualities that make them good for tinnitus, just as I mentioned before it's about just hearing something that isn't silence so that you're able to focus on something that isn't the tinnitus you're hearing. It should be noted, Sony themselves explicitly say they do not help with tinnitus, which is likely as true as me saying regular headphones don't "help treat" tinnitus. However, I am pretty much crippled without headphones if I have a really bad flare up.

I use almost the inverse of these, the Sony LinkBuds (and S series). These are Bluetooth earbuds that have a gap in the ear canal so you can hear the world around you. The LinkBuds S are closer to a standard pair of earbuds with the noise cancelling or pass-through sound options, which is over-all nicer due to being able to inherently block out sounds from the bus. Anyway all this to say, I only mentioned them because they're pretty similar to how I use my headphones.

I can't speak on how the CRE-C10's are or how effective they might be for my style of tinnitus, I'm merely making assumptions!
