Phonak’s AI revolution continues: new Infinio Ultra hearing aids with clearer sound and easier maintenance

Stäfa, Switzerland – October 21, 2025 – Phonak, a global leader in innovative hearing solutions, introduces Infinio Ultra, the next step in tackling two core challenges for hearing aid users: speech clarity from any direction and wax management.

The next generation of Phonak’s AI technology brings an even more natural listening experience with more efficient power management.

Wax buildup has been a challenge for hearing aid wearers, impacting performance and requiring frequent cleaning. This will no longer be the case with Phonak patented EasyGuardTM, a breakthrough in wax management for easier maintenance.

Infinio Ultra now brings the next level of Infinio performance to two new models, designed to adapt seamlessly to real life, connect effortlessly and help wearers hear even more clearly, every day:

Phonak Infinio Ultra Sphere In And Out Charger

Infinio Ultra, an easy-to-use solution for a more natural listening experience

  • Ultra adaptive - For a more natural listening experience

With 18x more real-world listening scenarios and 24% more precise environment detection, Infinio Ultra users will experience instant comfort and smoother transitions. Phonak AI sound classification system has been further trained to recognize a broader range of music styles, from Jazz to HipHop, Classical to Electronic.

  • Ultra connected - Connecting is simpler and more reliable than ever

With now one-step pairing to myPhonak, phones, and tablets, setup becomes effortless. Phonak universal connectivity enables pairing with as many as eight Bluetooth devices, while maintaining up to two simultaneous active connections. The updated myPhonak app gives easy access to essential adjustments with clearer language. 

Phonak Infinio Ultra Sphere Easy Guard

Ultra easy, no need to change wax filters anymore with EasyGuard

The new, patented EasyGuardTM, a break-through wax-management system, is mechanically sealed for extra protection with a membrane that is acoustically transparent, and it’s simple to wipe clean. Designed so that hearing aid wearers don't have to change wax filters means less fuss and up to 38% fewer service visits2. This marks a breakthrough beyond previous designs, dramatically reducing daily care and letting users spend more time wearing and enjoying their hearing aids.

The power and uniqueness of Phonak’s AI technology

  • Ultra clear speech from any direction with Infinio Ultra Sphere 

In 2024, Phonak introduced the world’s first hearing aid powered by a dedicated real-time large scale DNN chip delivering clear speech from any direction1 instantly. “Phonak’s AI innovation introduced last year was a true game changer for our industry, but we knew it was only the beginning of a new era.” says Oliver Frank, Vice President Phonak Marketing.” This year, we’re demonstrating our ability to push the technological boundaries even further in our pursuit of the best possible sound.” 

 

Unlike conventional AI approaches with small Deep Neural Network (DNN) that first classify the environment and then post-process sound, Phonak is the only one using a dedicated real-time large scale DNN chip to extract, enhance, and reintegrate voices from all directions, delivering clear speech from any direction instantly1. 

While each new generation of Phonak hearing aids incorporates increasingly advanced technology, life becomes simpler and more effortless for Phonak users. Rock legend Paul Gilbert, who recently tested Phonak’s latest innovation, shared his experience: “I've had the opportunity to try Infinio Ultra Sphere, and I would say to my musician friends, you've got to get those hearing aids, they make things so much easier.”

  • More efficiency means greater peace of mind about battery life

The dedicated real-time AI chip in Infinio Ultra Sphere has been optimized for even greater efficiency, and Spheric Speech Clarity 2.0 delivers clearer speech from any direction with up to 30% more efficiency than before. With its enhanced power management, a single charge provides all-day performance, even for active users in demanding, noisy environments.

Infinio Ultra R and Infinio Ultra Sphere will be available to order by licensed hearing care professionals as of October 22.
