Measured Metrics

SoundScore: 5 Acoustic Dimensions

Five independent measurements assess speech audibility, noise management, frequency response accuracy, feedback control, and directional performance. The purple SoundScore graph is the overall result, and the five graphs after it break it into individual measurements for the selected fit. Each curve shows how scores are spread across all tested hearing aids, and the dot and number mark the score for Phonak Audeo R Infinio 90.

Lab Assessment

Phonak Audeo R Infinio 90 Performance Verdict

The Phonak Audeo R Infinio 90 is a premium prescription behind-the-ear hearing aid released in 2024, priced at $4,996. In our lab testing, it earned an A grade with a SoundScore of 4.4/5, ranking #18 among 39 prescription hearing aids tested.

Speech clarity is a standout strength in our testing. Speech in quiet scored 4.4/5, a strong result that sits 1.01 points above the category average. Speech in noise performance is more mixed at 2.5/5—above the category average by 0.37 points, but only moderate in absolute terms. This pattern suggests the Infinio 90 excels in calmer listening environments while offering incremental benefits in challenging noise.

Streaming music quality impressed at 4.0/5, a strong score that lands 1.24 points above category average. Feedback handling scored 4.2/5, which is strong in absolute terms though 0.52 points below the category average. Own-voice comfort was mixed at 2.2/5, falling 0.50 points below average—something to discuss with your hearing care provider if natural voice quality is a priority.

The Infinio 90 competes in a crowded premium segment. At this price point, alternatives like the Phonak Sphere Infinio (4.98/5) and Oticon Intent (4.83/5) achieved higher overall scores in our testing. Buyers seeking Phonak's ecosystem and strong speech-in-quiet performance may find the Infinio 90 appealing, though those prioritizing noise performance or own-voice comfort should compare options carefully with their provider.

Test Documentation

Phonak Audeo R Infinio 90 Lab Observations

Our audiologists documented fit observations and detailed the test configuration used during evaluation. Notes are available for both Initial and Tuned conditions tested in our lab.

Lab Notes

Initial fit observations

In initial fit testing with a closed vented dome and medium-power receiver using Phonak's Adaptive Digital 3.0 formula, the Infinio 90 achieved a normalized score of 4.3/5. Speech in quiet started strong at 4.0/5, while speech in noise was limited at 1.6/5. Music streaming performed well at 4.2/5, and feedback handling was excellent at 4.6/5. Own-voice comfort measured 2.2/5, a mixed result. This configuration delivers solid out-of-box performance for quieter environments and media consumption.

Tuned fit observations

After professional tuning—maintaining the same closed vented dome and medium-power receiver—the normalized score improved to 4.6/5, a 0.3-point gain. Speech in quiet rose to 4.4/5, and speech in noise improved notably to 2.5/5. Music streaming remained strong at 4.0/5. Feedback handling decreased slightly to 4.2/5, still a strong absolute score. Own-voice comfort held at 2.2/5. The tuning process delivered meaningful gains in speech intelligibility without requiring coupling changes.
