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:
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.
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 visits1. This marks a breakthrough beyond previous designs, dramatically reducing daily care and letting users spend more time wearing and enjoying their hearing aids.
