Quick Verdict
AI summarizedSummarized with AI assistance from our human-researched product information, in-lab testing, objective sound measurements, and expert ratings.
The real choice here is noise performance versus natural sound and size: Infinio Ultra posts a measured speech-in-noise score roughly 1.9 points above Allure's, while Allure counters with a smaller build and a top design score, for about $200 less.
Audéo Infinio Ultra
Choose the Phonak Audéo Infinio Ultra if you regularly struggle in loud, chaotic environments like restaurants or parties — its lab-measured speech-in-noise score (4.4/5, tuned) is well above the site-wide average and clearly stronger than the Allure's, even though you'll accept a bulkier RIC body and about $200 more per pair.
Allure
Choose the Widex Allure if natural, low-distortion sound and a smaller, sleeker design matter more to you than aggressive noise suppression — it costs roughly $200 less per pair and matches Infinio Ultra on design and comfort scores, but its tuned speech-in-noise score (2.5/5) is a real step down and feedback handling dropped sharply to 1.7/5 after professional tuning.
What actually separates them
AI summarizedSpeech-in-noise performance
Lab measuredHearAdvisor's tuned lab scores show Infinio Ultra at 4.4/5 for speech in noise versus 2.5/5 for Allure — a large, measured gap that matters most if noisy environments are your biggest complaint.
Feedback handling after professional tuning
Lab measuredAllure's feedback (whistling) control actually fell to 1.7/5 once professionally tuned, a notable weak point; Infinio Ultra held up better at 4.2/5 in the same tuned condition.
Size versus design score
Hands-on reviewOur reviewer notes Infinio Ultra is a distinctly larger RIC due to its dual-chip hardware, while Allure earns a full 5.0/5 design score in our expert ratings versus 4.1/5 for Infinio Ultra — Allure is the pick if discretion and fit matter more than raw noise performance.
Price
PriceAllure runs about $200 less per pair than Infinio Ultra, a modest gap given both sit in the $4,400–$4,600 flagship range.

Ear SimulationEar SimulationThe outer ear, or pinna, can have a significant effect on the frequency shape of sound arriving at your inner ear. Some hearing aids mimic the "pinna effect" when producing sound, to deliver more natural sound to the listener.
Real Ear SoundReal Ear SoundReal Ear Sound simulates the performance characteristics of the pinna. This restores localization and the ability to experience natural sound perception.
Digital PinnaDigital PinnaThe central auditory system uses input from both ears to form spatial judgment, such as spatial awareness, localization, distance estimation, etc. The use of independent fast-acting compression in each ear can disrupt the loudness and timing relationship of sounds between ears (IID and ITD cues). This may alter the spatial relationship of sounds and lead to poorer spatial performance. The use of algorithms, such as the digital pinna, are designed to preserve the front/back localization cues.

Soft-level noise reductionSoft-level noise reductionProviding more gain for soft sounds (low compression thresholds) is good for amplifying soft speech but it can also mean soft unwanted sounds - such as the noise from fans, refrigerators, or even hearing aid microphone noises, are audible even when in quiet environments. The Soft Level Noise Reduction Algorithm differentiates unmodulated soft sounds from modulated soft sounds and reduces their amplification. This results in an enhanced sound quality for the user.
Occlusion ReductionOcclusion ReductionWhen ears are plugged, or occluded, by hearing aids the low frequencies from one’s own voice are amplified and may be uncomfortable. This effect is typically reduced in hearing aids through venting or open-fit models.

Bottom Line
AI summarizedThe Verdict
Infinio Ultra is the stronger pick for anyone whose primary complaint is following conversation in loud, crowded places — its tuned 4.4/5 speech-in-noise score is one of the best we've measured, and Phonak's Ultra firmware update specifically addressed the original Sphere's battery and connectivity weak points.
That performance comes in a noticeably larger body and at a slightly higher price.
Which is right for you?
Allure is the better fit for buyers who prioritize natural, low-distortion sound, a sleeker RIC form factor, and want to spend a bit less — but go in aware that our lab measured a real drop in noise performance and feedback stability once the device was professionally tuned, so it's a stronger choice for quieter lifestyles than for noisy ones.
What to ask at your fitting
AI summarizedInsist on real-ear measurement tuning
Both devices' lab scores shifted meaningfully after professional tuning — Infinio Ultra's speech-in-noise rose to 4.4/5 and Allure's feedback control fell to 1.7/5 — so ask your provider to verify the tuned fit, not just the default program.
Demo Infinio Ultra's Sphere mode in a noisy room
Ask your provider to let you compare the Automatic program against the dedicated Spheric Speech in Loud Noise mode, since AutoSense is what actually switches you into Infinio Ultra's strongest noise performance.
Try both physically in your ear
Infinio Ultra's dual-chip design makes it notably larger than typical RICs, while Allure is built for a smaller, sleeker fit — have your provider let you feel both before committing, especially if you wear glasses or have smaller ears.
Frequently Asked Questions
AI summarizedAllure runs about $200 less per pair and scores higher on design (5.0/5 vs 4.1/5) and matches Infinio Ultra on comfort, so it suits buyers prioritizing natural sound and a smaller fit. But its tuned speech-in-noise (2.5/5) and feedback handling (1.7/5) are notably weaker, so it's a better fit for quieter lifestyles.
Allure is the more discreet option — our reviewer notes Infinio Ultra is distinctly larger than typical RIC hearing aids because of its dual-chip DEEPSONIC architecture, while Allure earns a top design score in our expert ratings.
Yes, both are prescription devices fitted and tuned by a hearing care professional. Our lab data shows professional tuning changes outcomes meaningfully for both — Infinio Ultra's noise performance improved with tuning while Allure's feedback control worsened — so the fitting appointment matters for either choice.
Widex Allure offers about 25 hours of general use with 7 hours of streaming, while Infinio Ultra offers around 17 hours in normal use but only about 10 hours when its power-hungry Sphere noise-reduction mode is continuously engaged. Which is 'better' depends on whether you need Infinio Ultra's noise mode all day.
