Did Phonak fix the biggest problems with the Infinio Sphere?
I put the new EON Sphere through detailed testing, and there’s a lot to like:
âś… 25% smaller
âś… Longer battery life
âś… Better wind-noise control
âś… Earlier AI activation
âś… Auracast connectivity
âś… Improved receiver attachment
It keeps the impressive speech separation that made the original Sphere stand out, but it doesn’t provide more maximum noise reduction. Performance may also depend on using a properly fitted custom earmold rather than an open dome.
Most importantly, even advanced technology cannot overcome a poor fitting.
Proper programming, Real Ear Measurement, and comprehensive Audiologic Best Practices remain critical.
So, is EON Sphere better than Infinio Sphere? Watch my complete review for the test results, limitations, and everything you should know before upgrading.
