Phonak Audéo Sphere Infinio source record

Published sources describe the Audéo Sphere Infinio as a prescription receiver-in-canal device with a second DEEPSONIC processor intended for speech in noisy settings. Cited lab results report high speech-in-noise performance, while the physical size, shorter runtime in Sphere mode, professional-fitting requirement and reported price are material constraints. A qualified professional should assess fit and candidacy; confirm current model and seller details.

Reported strengths to verify

  • Independent lab sources report high speech-in-noise results for the dual-chip DEEPSONIC design (SoundScore 4.64/5 on the original and 4.58/5 on the Ultra refresh)
  • IP68 rated for dust and water resistance, suited to active and outdoor use
  • Rechargeable lithium-ion with up to about 56 hours per charge in standard use, plus fast charging
  • Modern Bluetooth (5.3 / LE Audio + Classic) with pairing to up to 8 devices and 2 active connections at once, and roughly double the range of older Phonak models
  • Fits a wide range of losses, from mild to profound

Worth checking

  • Larger physical form factor than several competing flagships, owing to the dual chips and bigger battery, so it is less discreet
  • The AI Sphere noise mode cuts battery life sharply (around 7 hours on the original model, roughly 10-11 hours on the Ultra refresh)
  • Prescription-only, so it needs a professional fitting and is not sold over the counter
  • Premium pricing, with the top I90 tier reaching roughly $4,598 per pair

Common questions

Is the Phonak Audéo Sphere Infinio available over the counter?

No. It is a prescription hearing aid that has to be fitted and programmed by a hearing-care professional, so it is not sold as an OTC device.

What makes the Sphere Infinio different from other Phonak hearing aids?

It adds a second dedicated AI chip (DEEPSONIC) alongside the main processor, used specifically to separate speech from background noise in real time. That is the basis of its Sphere noise mode and its strong speech-in-noise lab scores.

How long does the battery last?

Up to about 56 hours per charge in standard use. Running the AI Sphere noise mode draws more power and shortens that a lot (roughly 7 hours on the original model and around 10-11 hours on the Ultra refresh). It also supports fast charging, with a short top-up giving a few extra hours.

Is it waterproof and good for active use?

It carries an IP68 rating (1 m for 30 minutes) for dust and water resistance, which suits sweat, rain and active lifestyles. The manufacturer does not recommend it for lap swimming or full submersion during exercise.

What is the difference between the original Sphere Infinio and the Ultra version?

The Ultra is a free firmware update released in October 2025 for existing owners. It moves the device to AutoSense OS 7.0 and improves Sphere-mode battery life from about 7 hours to roughly 10-11 hours.
