The real choice here is speech clarity in noise versus price and battery life: the Infinio Ultra posts a notably stronger noise score but costs about $1,200 more, while the Omega AI is cheaper, lasts longer per charge, and still beats the site-wide average in noise, just by a smaller margin.
Choose the Phonak Audéo Infinio Ultra if you struggle most with speech in noisy places like restaurants and parties — its 4.4/5 speech-in-noise lab score is 2.87 points above the site-wide average and edges out the Omega AI, and you're willing to pay roughly $1,200 more for that edge and a slightly bulkier RIC shell.
Choose the Starkey Omega AI if you want strong all-around performance and wellness features (fall alerts, respiratory tracking) for roughly $1,200 less, and can accept a speech-in-noise score (2.9/5) that, while 1.37 points above the site-wide average, is a clear step behind the Infinio Ultra's absolute result.
Phonak's lab score of 4.4/5 is well ahead of Starkey's 2.9/5 in absolute terms, even though both beat the site-wide average — for buyers whose main complaint is following conversations in loud rooms, this is the single biggest differentiator.
The Omega AI runs about $1,200 less per pair than the Infinio Ultra, a meaningful gap for buyers without full insurance coverage.
Starkey's Omega AI offers more adjustment bands (24 vs 20) for a hearing professional to fine-tune during fitting, giving slightly finer control over how gain is shaped across frequencies.
Starkey's real-world battery rating of 4.6/5 reflects up to 51 hours per charge, well above the site-wide average of 3.9/5, while Phonak's Sphere mode is more power-hungry by design and rated for shorter intensive use.

The Verdict
If your hardest listening situations are crowded restaurants or parties and you're willing to pay a premium for it, the Infinio Ultra's speech-in-noise lab score of 4.4/5 is the strongest reason to spend the extra roughly $1,200 — just make sure your provider does a real-ear-measurement fitting, since Phonak's own data shows that step is what unlocks the device's full performance.
Which is right for you?
The Omega AI is the more sensible pick for buyers who want strong, broadly above-average performance, excellent battery life (51 hours), and a feature-rich wellness app, without paying flagship-noise-mode pricing. Its speech-in-noise result, while respectable relative to the site-wide average, isn't in the same league as the Infinio Ultra's, so buyers who prioritize noisy-environment clarity above all else should lean Phonak instead.
Phonak's own lab data shows the Infinio Ultra's tuned score jumped from 3.27 to 4.13 after professional tuning, so ask your provider to verify they're using real-ear measurements rather than default settings.
If fall alerts, respiratory tracking, or the Gen AI Assistant matter to you, ask to try the My Starkey app during your fitting since these are a bigger part of Omega AI's value than raw speech-in-noise scores.
Given the sizable gap in measured speech-in-noise scores (4.4 vs 2.9), request a trial or extended demo in a restaurant-like environment rather than deciding from the quiet fitting room.
The Phonak Infinio Ultra scores clearly higher, with a lab speech-in-noise score of 4.4/5 versus 2.9/5 for the Starkey Omega AI. Both beat the site-wide average, but Phonak's margin is larger in absolute terms.
It depends on your priority: the Infinio Ultra costs roughly $1,200 more but delivers a notably stronger measured speech-in-noise result, so it's worth it mainly if noisy environments are your biggest struggle. If price and battery life matter more, the Omega AI is the better value.
The Starkey Omega AI is rated for up to 51 hours per charge under normal use, while the Phonak Infinio Ultra offers around 17 hours normally and about 10 hours when its power-hungry Sphere mode is active. Starkey's battery score of 4.6/5 reflects this longer runtime.
Yes, both are prescription hearing aids fitted and adjusted by a hearing care provider, not self-fit OTC devices. Both also support remote follow-up care through their respective apps.
