I pulled out out of the fitting software. Tier comparisons and fitting ranges are going to be pretty identical to the lumity with the exception that if you get the sphere model you have access to the AI program.
Presumably it will just flip out of the AI program and back into the regular speech in noise program unless your clinician has turned off the limit, or if they have it will just continue in the AI program and give you a low battery beep earlier in the day.
I wouldn’t upgrade from the lumity if you already had it unless you were going to the sphere. If you don’t have the lumity already and are just holding off on upgrading, then getting to infinio over the lumity would probably be a cost comparison. There ARE improvements with the infinio, so unless you can get an extra good deal on the lumity I’d probably lean towards the infinio. I’m just expecting it to be a much more modest improvement than if one was getting the sphere. Along the lines of Marvel to Paradise, or Paradise to Lumity.
