Well usual disclaimer, I’m a huge Starkey fan. Of the brands listed the rest are foreign imports, Starkey is American, and in many areas of hearing aid technology lead the world. Including feedback cancellation, which will allow the aids to deliver better sound to your ears in those higher frequencies with less chance of distortion or whistling.
That feedback cancellation system is going to come in very handy if for example you wear CIC hearing aids, and you then put on a set of headphones like Bose Noise Cancelling on the plane. The weaker the feedback cancellation system, the more likely the aids are to whistle if you put other devices near them or cover them.
I’ve fitted Starkey CIC aids to your type of loss many times before. Nice and discrete, the same brand worn by all the United States Presidents who have ever worn hearing aids (Clinton, Carter, Bush Sr, and Reagan); and let’s face it it’s not like they couldn’t order any brand they wanted to.
The new Voice IQ2 system on the top of the line Starkey aids (at cost price it’s not going to be much extra to simply buy top of the line), can cut background noise by up to 20dB, delivering remarkable clarity in a social situations. For a bit more money you can put the same technology in the IIC, which goes in deeper and is even more invisible. But that depends on the shape of your ear canal.
The only suggestion I have regarding cell phone is that you’d need a Bluetooth device that doesn’t try and go way into the ear. Because obviously you’d be wearing a hearing aid there. Just get one, like my Motorola one that sits over the ear canal, but doesn’t try to go down it.
If I could not choose Starkey of the other brands you mentioned, I like Oticon, and think Siemens, Phonak and Unitron are kind of fair to middling.
