I have been SSD since surgery in 2011. I waited 3 yrs then got the Cochlear BAHA 4 in Dec 2014. I had a hard time adjusting to it and found myself pretty unhappy most of the time with it's performance and didn't wear it much. I believe that mine was not functioning properly most of the time though as I had it fixed twice in the 2 year warranty period.
I have just upgraded to the BAHA 5 Power and so far I love it!! The sound is so much better. I can actually hear someone on my deaf side,, which I never could with the 4. It is blue tooth capable and if you have an IPhone,, it pairs with that and there is even an app to help with controls. Pairs for phone calls, streaming music etc, and phone can be used as a microphone during meetings or conversations at the table,,,, I haven't even tried all of it's capabilities yet! It even has the ability to find the device if lost,,,,
,,, basically tells you if you are close or far from it, ,,VERY helpful,,,
Clarice has good points about her device that also relates to the Cochlear BAHA,, I have difficulty wearing a ball cap but don't often,, I can sit on the couch with no interference until I turn my head,, not much of a bother. I have not had any infections and only minor irritation at the site a couple of times. Usually cleaning with a small brush that's provided and a q-tip of alcohol,,,
I agree that you should find an audiologist who is trained in BAHAs,, either manufacturer,, as they are more informed about the devices. They will also be able to program your device once you receive it. I travel an hour out of town to my audiologist because she is trained with the BAHA. She has been a wonderful source of knowledge to answer my questions,,,,
Good luck to you,, you can also pm me if you'd like discuss anything,,
Directionality is still a problem but will be with any aid I believe.
