Phonak Infinio Sphere 90 and other models

The Phonak Audéo Sphere™ Infinio represents a major step forward in hearing technology through the use of artificial intelligence. At the core of its design is the world’s first dedicated AI processor in a hearing aidPhonak’s DEEPSONIC™ DNN chip—working alongside its established ERA processor. This dual-chip architecture enables the device to process sound in real time, referencing over 22 million real-life sound environments to deliver context-aware adjustments.

The result is Spheric Speech Clarity, a feature that improves the signal-to-noise ratio by up to 10 dB, allowing users to hear speech more clearly from any direction, even in complex or noisy settings. This AI-driven capability is especially useful in situations where multiple conversations or background noise would previously make understanding difficult. Phonak’s AutoSense OS™ 6.0 also benefits from AI input, automatically recognising and adapting to seven unique sound environments, such as speech in noise, music, or car travel. AI enhances the OS’s ability to fine-tune settings for speech enhancement and listening comfort, reducing listening effort by up to 45%. Other intelligent features include motion sensors, which detect whether the user is moving or stationary and adapt microphone focus accordingly, and Environmental Balance, which blends environmental sound with streamed audio for a more natural experience. In addition to these AI capabilities, the Sphere offers universal Bluetooth connectivity, supports LE Audio and Auracast, and integrates with the myPhonak app, where users can adjust settings, track usage, and find their devices via GPS. Clinician and user feedback strongly support the AI performance: 100% of professionals rated it as delivering outstanding hearing, with significant reductions in listening effort in real-world tests. In short, the Phonak Audéo Sphere Infinio puts artificial intelligence at the heart of the hearing experience—transforming how users interact with their surroundings by continuously learning, adapting, and improving speech clarity wherever they go.

  • Choose Bolero (Marvel/BTE) if you need a traditional BTE fit, possibly require greater battery capacity, or prefer a slightly larger and simpler device without AI.
  • In short, Sphere leads in AI-driven noise control and speech clarity, while Bolero offers a reliable, traditional BTE choice with robust performance and options. Both benefit from Phonak’s quality build, connectivity, and accessory compatibility, so the best pick comes down to your lifestyle needs and listening environments.

Phonak Bluetooth hearing aids: things to know

Phonak’s Bluetooth-enabled hearing aids—such as Paradise, Lumity, Infinio, and Infinio Sphere—offer universal connectivity via Bluetooth Classic, allowing pairing with up to eight devices and simultaneous connection to two active devices. This ensures seamless streaming of calls, music, TV audio, and navigation instructions across both iOS and Android platforms

  • The Infinio platform, utilising the latest Bluetooth 5.3, nearly doubles wireless range compared to earlier models, with outdoor streaming distances of up to 108 metres on iPhones and 206 metres on many Android devices. These devices are also future-ready for LE Audio and Auracast, pending a firmware update—offering more efficient, low‑latency audio streaming and broadcast capabilities in public venues
  • Through the myPhonak app, users can adjust volume, switch programmes, configure tap controls, and access a “Find My Hearing Aids” feature, along with remote support from hearing-care professionals
  • However, some users caution that automatic switching between paired devices can occur unpredictably. One Lumity user stated:
  • “Their HCP can change the programming so that you manually change to the TV connector program when you want it.”
  • Phonak also supports a range of accessories like the TV Connector, Roger microphones, PartnerMic, and RemoteControl, all of which leverage Bluetooth streaming for added support in social situations.

Things to Know

Adopting Phonak Infinio Sphere: pros and cons

The Phonak Audéo Infinio Sphere is Phonak’s most advanced Receiver-in-Canal (RIC) hearing aid to date, powered by a dual-chip system including the groundbreaking DEEPSONIC AI processor. Below is a balanced breakdown of the strengths and potential trade-offs based on real user feedback and expert testing.

✅ Pros

  • Exceptional Speech Clarity in Noise: The Sphere mode offers industry-leading noise reduction, with users reporting speech is clearer even in loud environments like restaurants or supermarkets. Real-time AI adapts to dynamic situations, boosting speech from any direction. One user described hearing in noise as “the clearest I’ve experienced since my hearing loss.”
  • AI-Driven Features: Powered by a dedicated DEEPSONIC AI chip, Sphere dynamically improves speech-to-noise ratio by up to 10 dB. Auto activation of Sphere mode saves battery by engaging only when needed.
  • Advanced Bluetooth & Connectivity: Bluetooth 5.3 supports up to 8 paired devices and 2 simultaneous connections. Streaming is stable, with minimal dropouts, and it is Auracast-ready for future public broadcast audio compatibility.
  • Strong App Integration: The myPhonak app offers full control over volume, programmes, noise reduction, and more. Includes a “Find My Hearing Aids” feature and remote programming options.
  • Improved Everyday Performance: Effective for diverse situations: from conversations in cars to noisy shops. Compatible with Roger microphones and accessories for group environments.

⚠️Cons

  • Larger Size: Slightly bulkier than previous Phonak RIC models due to its dual-chip setup. While most users find it comfortable, those who wear glasses or prefer smaller devices may find it noticeable.
  • Reduced Battery Life in Sphere Mode: Battery life drops to around 7 hours during prolonged Sphere mode use, compared to the usual 16+ hours. However, some users reported better-than-expected battery performance in mixed usage.
  • ChargerGo Design Limitations: Lightweight charger can feel unstable, especially when using larger earmoulds. Some users found placement in the charging dock awkward.
  • Initial Bluetooth Setup Can Be Tricky: Pairing for the first time may require multiple attempts or support from an audiologist.
  • Not Yet Fully Auracast Functional: While hardware-ready, full Auracast functionality requires a pending firmware update.

🧰 Verdict

For users prioritising speech clarity in noisy settings and advanced AI features, the Infinio Sphere offers one of the best solutions available—despite modest compromises in size and battery runtime.

In summary, Phonak combines a venerable Swiss heritage with cutting-edge tech across diverse form factors, prioritising adaptive connectivity and holistic user support in its global ecosystem.
