If you get a chance, do some reading on the category cochlear implants forum. Lots of helpful information.
Some of us had problems with the Kanso 2 not holding well to the newer 600 series Cochlear implants, ci612, ci622 and ci632 implants. Swelling is usually the problem but some of us just have thick skin. It took me about 3-4 months for the swelling to go down enough for the K2 to hold with the #5 magnet. @debbie_o uses the K2, she will chime in if needed. I actually wear the N7 during the day then put the K2 on in the evening. I use an android phone, the Google Pixel 3 that streams without any intermediate device. The N7 and K2 processors need Android 10 or higher to do this or you could also use most any Apple phones, iOS without an intermediate device.
Each of us are different concerning hearing. Some get speech understanding faster than others but most always do within a month or two. Then it just gets better. Pretty amazing technology.
