Phonak Infinio Ultra i70 R hearing aids overview
The i70 R comes with AI-trained AutoSense OS 7.0, key speech enhancement features, universal Bluetooth connectivity, and the same 20 fine-tuning channels as the i90 R.
The main differences are minor: StereoZoom 2.0 must be activated manually, and tap control is not automatic. For many users, these small compromises make premium Phonak technology significantly more affordable.

How the i70 R Adapts to Different Environments
The Phonak Infinio Ultra i70 R uses AI-trained AutoSense OS 7.0, refined over seven generations and trained on thousands of real-world sound environments. It automatically recognises your surroundings—quiet home, busy street, restaurant, or car—and adjusts the hearing aids accordingly.
The i70 R includes all eight AutoSense OS 7.0 programs:
-
Speech in Loud Noise

SmartSpeech Technology
SpeechSensor monitors your environment from all directions, detecting where speech is coming from. If someone speaks from the side or behind, the hearing aids adjust automatically, so you don’t miss important conversations.
Speech Enhancer identifies and boosts soft speech in quiet environments, making it easier to hear without asking people to repeat themselves.
Dynamic Noise Cancellation reduces steady background noise while keeping speech clear. In noisy cafés or cars, it minimises distractions without affecting the voices you want to hear.
Motion Sensor Hearing detects when you’re moving versus stationary and adjusts processing to maintain speech clarity even while walking.
These features are not minor tweaks—they meaningfully improve speech understanding in everyday life.
Music
The i70 R handles music beautifully. AI-trained recognition distinguishes different music types and automatically adjusts processing. The Music program provides a wider frequency response and reduced compression, making music sound rich and natural in daily use.
Speech Understanding in Varied Environments
In restaurants, social gatherings, or workplaces, the combination of SpeechSensor, Speech Enhancer, and Dynamic Noise Cancellation maintains clear speech. In very noisy settings, you can manually activate the Speech in Loud Noise program, which engages StereoZoom 2.0 to focus on the speaker in front of you.
APD 3.0 Precision Fitting
The i70 R uses Phonak’s APD 3.0 fitting prescription, providing precise gain across all frequencies. Combined with 20 fine-tuning channels (same as the i90 R), it allows a highly customised fit for your specific hearing loss.
Universal Bluetooth Connectivity
The i70 R supports reliable universal Bluetooth for iPhone, Android, laptops, and tablets. You can pair two devices simultaneously, with double the transmission range of previous models. Two-way phone call streaming is stable, making it practical for daily use.
It’s also ready for Auracast broadcast technology, allowing future connection to public sound systems.

Researching for a Loved One
If you’re looking into hearing aids on behalf of someone else—whether a parent, partner, or friend—you’re not alone. Many people research options for family members who have struggled with hearing loss, and it’s one of the most thoughtful steps you can take.
The next best step is booking a consultation. You’re welcome to attend with them, as many family members find it helpful to be part of the discussion.
Our audiologists can assess whether this technology suits their hearing loss and lifestyle, answer any questions, and explain what modern hearing aids can realistically achieve. There’s no obligation—just expert guidance and support.
Ultra R or Sphere: Which Do You Need?
-
Infinio Ultra R: Ideal if you want premium hearing aid technology with excellent sound quality and adaptation across varied environments, but you don’t often face extremely challenging multi-speaker situations.
-
Infinio Ultra Sphere: Better if speech understanding in noisy, multi-speaker environments is a significant challenge, and you want advanced technology capable of handling situations previous hearing aids couldn’t.
Conclusion
The i70 R delivers what really matters: the full SmartSpeech Technology suite (SpeechSensor, Speech Enhancer, Dynamic Noise Cancellation, Motion Sensor Hearing), AI-trained AutoSense, and the same 20 fine-tuning channels as the i90 R.
You get advanced speech processing, seamless automation, and premium build quality—essentially everything that improves speech understanding in daily life.
The trade-offs? StereoZoom 2.0 requires manual activation rather than automatic, and you use your phone instead of tap control.
