Bottom Line
AI summarizedThe Verdict
If your biggest struggle is following speech in noisy places — restaurants, parties, meetings — the data points clearly to the Phonak Audéo Infinio Ultra: it scored 4.4/5 on speech-in-noise in tuned lab testing versus 2.7/5 for the Horizon Go IX, and it costs roughly $350 less per pair.
That combination of stronger measured performance and a lower price makes it hard to justify the Horizon Go IX on noise performance alone.
Which is right for you?
The Horizon Go IX still has a place: it holds a more conventional RIC shape (versus Infinio Ultra's notably larger shell), strong build and comfort scores, and hands-free calling support, so it suits buyers whose environments are calmer and who prioritize a smaller, more discreet device over noise-fighting horsepower. Both share a real weakness in own-voice comfort, so raise that at the fitting regardless of which you choose.
What to ask at your fitting
AI summarizedTest Sphere mode in a noisy room
Ask your provider to demo Infinio Ultra's Spheric Speech Clarity in a real noisy setting, since that mode — not the standard program — is what drives its 4.4/5 speech-in-noise score.
Discuss own-voice comfort with your provider
Both devices show weak own-voice comfort in lab tuning (1.8/5 for Horizon Go IX, 2.8/5 for Infinio Ultra), so raise this specifically if you're sensitive to hearing your own voice through the aid.
Try Infinio Ultra for fit if you have small ears
Because Infinio Ultra's shell runs larger than a typical RIC, have your provider check fit against glasses or smaller ears before committing, especially if size/discretion matters to you.
Frequently Asked Questions
AI summarizedThe Infinio Ultra is the cheaper of the two, running about $350 less per pair than the Horizon Go IX.
Yes. Our hands-on review notes that Infinio Ultra's dual-chip design makes it noticeably larger than typical receiver-in-canal hearing aids, which the Horizon Go IX does not share.
Yes, both are prescription devices fitted and tuned by a hearing care provider, and lab testing shows professional tuning meaningfully improves performance on both — Horizon Go IX's tuned score rose to 4.3/5 and Infinio Ultra's rose to 5.2/5.
Horizon Go IX offers about 28 hours of typical use per charge. Infinio Ultra offers around 17 hours in normal use, dropping to about 10 hours when its power-intensive Sphere mode is continuously engaged.
