Phonak Infinio Ultra i70 R – Overview

The Phonak Infinio Ultra i70 R is the advanced-level model in Phonak’s new Infinio Ultra lineup.

While it sits just below the premium i90 R, it still delivers highly capable performance through AI-trained sound classification, the full SmartSpeech Technology suite, and strong automatic processing. It’s an excellent choice for people who want advanced hearing performance at a more accessible price, without losing the core technologies that genuinely improve speech understanding.

Quick Highlights

• AI-trained sound processing

• Full SmartSpeech Technology suite

• Fully rechargeable

• Universal Bluetooth connectivity

• Swiss engineered

• Available colours: Sand beige, sandalwood, chestnut, champagne, silver grey, graphite grey, velvet black

• Accessory compatible with: Roger On, Roger Select, Roger Table Mic, Roger Clip-On Mic, and the myPhonak app

Advanced Automatic Sound Processing

The defining feature of the Infinio Ultra i70 R is how much advanced technology you get without needing the premium model. Using AI-trained sound classification, the device recognises your acoustic environment and adjusts its settings automatically — whether you’re relaxing at home, having a conversation in a café, walking outdoors, or working in a busy environment.

This gives you strong automatic performance with minimal manual input.

StereoZoom 2.0 is available at this level, but operates as a manual programme rather than activating automatically. You simply select the programme when you need extra focus in very noisy places.

Daily listening remains smooth and natural thanks to the ERA chip platform, which processes sound quickly and supports clearer transitions between environments.

AutoSense 7.0 – Automatic Processing Across the Day

The i70 R features AutoSense 7.0, Phonak’s latest generation of automatic sound adaptation. Trained on thousands of real-world scenes, it can accurately distinguish things like:

• Quiet conversations

• Busy restaurants

• Speech vs. background noise

• Speech vs. music

• Movement between acoustic environments

• AutoSense continuously analyses your surroundings and adjusts the programme, microphone settings, and processing features in real time. It’s seamless, reliable, and requires no effort from you.

This is the same AutoSense system used in the i90 R — the only difference is how certain supporting features (like StereoZoom 2.0 or tap control) are activated.

Strong All-Round Speech, Music & Everyday Performance

The Infinio Ultra i70 R delivers excellent day-to-day performance across speech, noise, and music. With SmartSpeech Technology — including SpeechSensor, Speech Enhancer, Dynamic Noise Cancellation, and Motion Sensor Hearing — conversations remain clearer whether you’re in quiet settings, outdoors, or in busier environments.

When environments become very loud or crowded, you can manually activate the Speech in Loud Noise programme to engage StereoZoom 2.0, giving you a narrow, focused listening beam for improved speech clarity.

Music performance is handled intelligently. The system recognises different music types and adjusts processing to give a more natural sound — clearer, richer, and more detailed whether listening through speakers, headphones, or live performances.

Fitting precision is enhanced through APD 3.0, which allows more accurate gain adjustments at each frequency. With 20 fine-tuning channels (the same as the i90 R), the i70 R can be programmed very precisely to your hearing loss.

Connectivity is another strength. Universal Bluetooth supports iPhone, Android, tablets, and laptops, with two simultaneous pairings and stable two-way audio for calls.

The device is also Auracast-ready, meaning it will support future public broadcast audio systems as they roll out.

Who Is the i70 R Best For?

The Infinio Ultra i70 R is ideal if you:

• Want high-quality automation without paying for the premium tier

• Spend most of your time in quiet to moderate noise

• Use Bluetooth regularly for calls and streaming

• Want rechargeable, reliable, easy-to-use hearing aids

• Don’t often encounter extremely loud or chaotic environments

If you frequently deal with heavy noise, multiple speakers, or complex sound environments, the i90’s advanced speech handling may be worth the upgrade.

What You Lose When Stepping Down from i90 to i70

While the i70 R is still highly capable, it has fewer advanced features than the i90. The main differences include:

• Less advanced SmartSpeech performance — The i90 includes the full SmartSpeech suite, offering better speech clarity in loud, challenging environments. The i70 handles moderate noise well but struggles more in very busy places.

• Reduced music optimisation — The i70 still processes music intelligently, but lacks some of the premium-level genre-specific enhancements found in the i90.

• Less adaptive directionality — The i90 can more precisely track and enhance speech from different directions, especially when multiple speakers are present.

• Lower-level noise management — Noise reduction is still strong, but not as aggressive or refined as the i90.

• Fewer automatic transitions — The i90 offers smoother, more seamless adjustments across sound environments due to its higher processing tier.

Overall, the i70 is excellent for day-to-day hearing but won’t deliver the same high performance in very noisy, complex listening situations as the i90.

Overall

The Phonak Infinio Ultra i70 R provides a well-balanced mix of AI-trained processing, strong automation, and reliable connectivity at a more affordable technology level. While it doesn’t offer the full performance suite of the i90, it still delivers excellent clarity and comfort for most everyday environments.

It is available exclusively through qualified hearing care professionals to ensure accurate fitting and the best possible results.
