In what way? I have found them pretty easy to fit. It feels like they are ALL I am fitting lately, which makes me uncomfortable because I don’t love being narrowed down to one manufacturer. But people are loving them. I think that from a physical fit perspective there are some small changes that have been made that make them generally a more comfortable fit for a greater number of people as compared to Phonak’s previous devices. The domes are better, the wires are better, the buttons are better, the cutom tips are better. Previously, Phonak had been weaker on these things compared to other manufacturers. From a sound quality perspective patients are also loving them. I have found that fitting to prescriptive target has actually required a bit more tweaking than their previous line. They are better at providing high frequency gain (improved /s/ access) while simultaneously sounding less sharp than prior models. Note, however, that I am a heavy DSL fitter which is not necessarily uncommon in my area but atypical worldwide (DSL targets come out of a Canadian lab associated with the school that trains a good chunk of Canadian audiologists), so I can’t speak as easily to how true the NAL fitting is right off the mark. I also do not “ease” patients into full gain if I can avoid it–patients are of course individual, but if they can tolerate full prescribed gain from the get-go I’ll go straight there. So I cannot comment on how the user “experience” adjustment function works.
The app is lame. The wax filters are poor (well, not the filters themselves but the replacement mechanism). The multifunctional button on the rechargeable aids is confusing for some patients. I wish there were a remote available. There is wide variability on how the phone connectivity affects the battery, which has made setting expectations difficult. The loss of DECT phone compatibility sucks. Nothing is ever exactly what I want it to be. But on the whole, I feel like Marvel is going to sweep 2019 the way the Opn seemed to sweep a few years ago.
