Yes there are various models of Resound BTE as I told you in the previous post you should see for the Resound Key, there are also the Enzo but they are more expensive and also bigger because they are with 675 battery for severe to profound hearing loss. I’m 40 years old and I wear the Phonak Naída Paradise P90-UP with 675 batteries and closed silicone earmolds for my hearing loss which is profound.
