Phonak Audeo Sphere Infinio: A Closer Look

Discover the Phonak Audeo Sphere Infinio at Hampstead Hearing. Explore its AI tech, pros and cons, and find out if it’s the right hearing aid for you.

Choosing a new hearing aid is a big decision. At Hampstead Hearing, we keep up to date with the latest technology so our patients can make informed choices. One of the most talked-about launches this year is the Phonak Audeo Sphere Infinio.

Phonak has introduced some impressive innovations, especially when it comes to hearing clearly in noisy places. But like any hearing aid, it’s not without its trade-offs. Below, we break down the main features — highlighting both the advantages and the points worth considering.

The Technology at the Heart of Infinio

Clearer Speech in Background Noise

What’s new: Phonak’s DeepSonic chip, powered by artificial intelligence.

Why it matters: It separates speech from background noise, trained on more than 22 million sound samples.

The result: Up to 36.7% better speech understanding in noisy environments.

What to keep in mind: Advanced processing uses more battery power, which may mean shorter life in busy environments.

Smarter Automatic Adjustments

What’s new: AutoSense 6.0, an upgrade from Phonak’s previous system.

Why it matters: It instantly adapts to seven listening situations, so you don’t have to keep adjusting settings yourself.

The result: Less effort, more natural focus on conversations.

What to keep in mind: While automatic, it isn’t perfect for everyone — some patients still prefer manual control at times.

Strong Connectivity Features

What’s new: Classic Bluetooth with universal compatibility.

Why it matters: You can pair to almost any device — phone, laptop, tablet — and even connect to two at once.

The result: Hands-free calls, stable streaming, and readiness for future Auracast technology.

What to keep in mind: Hands-free calling can struggle in very noisy places, meaning callers may not hear you clearly.

A Fit for Different Hearing Loss Levels

What’s new: Support for ActiveVent receivers, which automatically open or close depending on your environment.

Why it matters: More natural sound in quiet, more clarity in noise, and richer music during streaming.

The result: A single hearing aid that adapts across a wide range of listening situations.

What to keep in mind: The design is slightly larger than some ultra-discreet models, which may be a consideration for patients wanting the smallest option possible.

Durability and Everyday Reliability

What’s new: A reinforced build across the Sphere range.

Why it matters: Stronger hearing aids mean fewer breakdowns and more confidence in day-to-day use.

The result: A practical upgrade for anyone who relies on their devices all day, every day
What to keep in mind: The Infinio is currently only available in a rechargeable format — there’s no disposable battery option.

What’s Missing From The Phonak Audeo Sphere Infinio?

Despite its cutting-edge features, the Audeo Sphere Infinio does not currently include:

A telecoil, which is important for patients who regularly use hearing loop systems.

CROS compatibility, so it isn’t suitable for those with single-sided deafness.

The Bottom Line from Our Audiologists

The Phonak Audeo Sphere Infinio represents a big step forward in hearing technology. Its AI-driven DeepSonic chip, smarter AutoSense 6.0, and market-leading connectivity make it one of the strongest options available today.

However, it’s not perfect for everyone. The rechargeable-only design, slightly larger size, and lack of telecoil or CROS features may steer some patients towards other Phonak models or alternative brands.

At Hampstead Hearing, we take the time to understand your hearing profile, lifestyle, and preferences before recommending a solution. The Infinio could be ideal – but the right hearing aid is always the one that fits you best.
