I used to use frequency transposition when it first came out with my Phonak. Then, the second generation came out of Sound Recover, named “Sound Recover 2” and it seemed to be very flexible.
Since I now have a cochlear implant (by Cochlear) in one ear, I switched brands to Resound which has a very very basic sound recover type of technology. I asked them if they had plans to add more creativity (there’s different variations available with Phonak from what I’ve read) and they said no. I thought I had benefit from Resound’s sound transposition, but when I had it turned off, I heard things that I’d assumed were a part of sound shifting is the best way to describe it: with my mild to profound hearing loss, some regions aren’t worth aiding and some are and yet when I upgrade (usually every 8-10 years with the highest tier tech) I notice such a difference!
This is undoubtedly due to the hearing aid itself being so much better as well.
I seem to think Sound Recover 2 would be wonderful for me, but given Resound and Cochlear’s Alliance, it’s best to stick with these brands.
I suppose I could trial a Phonak and also a Resound the next time I buy a hearing aid. But it would be quite confusing I would think, to me.
Plus, there’d be no bilateral phone calls since they each use a different type of Bluetooth (Cochlear uses what Resound uses, Low Energy MFi), although if Phonak decides to utilize 5.2 LE Audio then that could change but that’s for the future.
