Phonak
The hearing aid most recommended by hearing care professionals worldwide — expertly fit and verified with Real Ear Measurement at our Freehold office.
Swiss Precision, Built for Real Life
Phonak is one of the most trusted names in hearing care — a Swiss company with over 75 years of engineering heritage, fitting hearing aids in more than 100 countries, and the most prescribed hearing aid brand among hearing care professionals globally.
What distinguishes Phonak is not any single feature but a consistent engineering philosophy: build hearing aids that handle the full complexity of real-world listening automatically, precisely, and without requiring the wearer to manage them.
At Haynie Audiology, we fit the full Phonak lineup, and every device is verified to your specific hearing and ear anatomy so you experience the full benefit of what Phonak's platform can deliver.
The AutoSense OS Difference
Every major hearing aid brand has an approach to automatic sound processing — a way of detecting what environment the wearer is in and adjusting accordingly. Phonak's approach, AutoSense OS, is the most sophisticated iteration of this idea in the industry.
AutoSense OS scans the acoustic environment 700 times per second and automatically blends between more than 200 distinct listening programs in real time — without any manual input from the wearer. Quiet conversation, noisy restaurant, outdoor wind, music, phone call, driving in a car — AutoSense OS detects each environment and applies a precisely calibrated response, seamlessly and continuously. The wearer does not switch programs. The wearer does not touch a button. The hearing aid handles it.
For patients who want hearing aids that simply work — that require no management, no adjustment, no attention — AutoSense OS is one of the most compelling arguments for Phonak. It is the foundation on which every current Phonak platform is built, and it represents decades of refinement in automatic environmental classification.
The Sphere Advantage — AI That Separates Speech From Noise
Phonak's strongest technical story in 2025 and 2026 is speech separation in noise — and it is a story backed by independent verification.
The top-tier Phonak Sphere devices — the Audéo Infinio Ultra Sphere and the new Audéo EON Sphere — include a dedicated AI chip whose sole function is separating the voice you want to hear from competing noise. This is architecturally distinct from standard noise reduction, which reduces background sound broadly. The Sphere's dedicated chip identifies the specific voice of interest, enhances it, and reduces everything else — a targeted speech separation process that most closely mirrors what a healthy auditory system does naturally.
HearAdvisor, the independent audiological testing laboratory, ranked the Audéo Infinio Ultra Sphere number one for speech in noise out of all prescription hearing aids tested — a result that reflects the measurable difference this dedicated AI approach makes in the most demanding listening conditions. For patients whose primary challenge is understanding speech in noisy environments — restaurants, family gatherings, meetings, crowded events — this is the most independently verified solution currently available.
Universal Connectivity — Any Device, Any Platform
Phonak has a connectivity advantage that is worth understanding before choosing a hearing aid platform. Most hearing aid brands offer Made for iPhone compatibility — direct streaming from Apple devices only, with Android streaming requiring an intermediary device or a less seamless connection. Phonak's Universal Bluetooth connectivity streams directly and natively from both iPhone and Android devices without compromise — calls, music, podcasts, and television delivered to both ears from any modern smartphone.
Current Phonak platforms also support Roger technology — Phonak's proprietary remote microphone system, widely regarded as the most advanced and effective assistive listening technology available. Roger microphones transmit the speaker's voice directly to the hearing aid, cutting through distance and background noise in ways that no hearing aid microphone system alone can match. For patients who frequently face difficult listening environments — large conference rooms, group dining, lectures, outdoor conversations — Roger is a meaningful clinical tool.
Tinnitus Support
Phonak hearing aids include built-in tinnitus management programs — broadband noise and customizable sound therapy options that can be used alongside a structured tinnitus management plan. For patients managing both hearing loss and tinnitus, these features are accessible through the myPhonak app and can be adjusted at any appointment. If tinnitus is a primary concern alongside hearing loss, a comprehensive tinnitus evaluation helps determine the right combination of hearing aid and therapy approach for your specific presentation.
The Phonak lineup
Phonak offers a range of hearing aids to suit different needs, preferences, and hearing loss profiles. We fit and verify each one at our Freehold office:
-
Audéo EON Sphere — Phonak's newest 2026 flagship. A smaller, lighter Sphere device built on the new HYPERSONIC chip with up to 38 hours of battery life and the same dedicated speech separation AI that defines the Sphere platform.
-
Audéo Infinio Ultra Sphere — HearAdvisor's number one rated prescription hearing aid for speech in noise. Dual-chip architecture — ERA processing chip plus dedicated DEEPSONIC AI chip — delivering the most independently verified speech clarity in noise of any hearing aid currently tested. Up to 56 hours of battery life.
-
Audéo Infinio Ultra R — The Infinio Ultra platform's outstanding AutoSense OS 7.0 processing without the dedicated Sphere AI chip. Excellent automatic sound management in a rechargeable RIC at a more accessible price point than the Sphere models.
-
Virto R Infinio — Phonak's smallest rechargeable in-the-ear hearing aid ever made. Full Infinio ERA chip and AutoSense OS 7.0 in a custom-fit device. RogerDirect compatible. For patients who want Phonak's flagship processing in a nearly invisible form factor.
-
Audéo Lumity — The previous Phonak flagship, now widely available as a proven, clinically established option. SmartSpeech technology, AutoSense OS 5.0, and a track record of strong real-world performance at a more accessible price point than the current Infinio generation.
Each of these is explained in more detail on its own page — and part of our job is helping you understand which platform truly fits your hearing loss, your lifestyle, and your daily listening demands.
Why the fitting matters as much as the device
HearAdvisor's number one speech-in-noise ranking for the Phonak Infinio Ultra Sphere was achieved in a best-practices audiologist-optimized fitting — which means real ear measurement verification was part of the process. Manufacturer defaults, applied without objective verification, frequently over- or under-amplify — a leading reason hearing aids end up unused regardless of how good the underlying technology is.
At Haynie Audiology, every Phonak fitting follows a verified, best-practice protocol built around Real Ear Measurement — a probe microphone placed at the eardrum confirms your devices are delivering precisely the right amplification for your specific ear canal anatomy and hearing profile. The Sphere's AI is only as powerful as the amplification it is built on top of. Verification is what closes the gap between what a hearing aid can do and what it actually does in your ear.
