TL;DR: Phonak hearing aid customization at Direct Hearing means professional programming by a licensed hearing care provider using the same manufacturer software traditional clinics use, conducted entirely remotely. Your hearing aids arrive pre-programmed to your audiogram, and your first fitting appointment fine-tunes everything from AutoSense OS behavior to myPhonak app settings. Unlimited follow-up adjustments are included for as long as you own your devices. Take our free online hearing test to get started.
Most people picture hearing aid customization as a dial on the side of a device. Turn it up, turn it down. In reality, professional Phonak hearing aid customization is a layered process involving precise audiogram-based programming, environment-specific adjustments, and ongoing fine-tuning that takes weeks of real-world use to complete.
The stakes are real. Research published in JAMA Network Open found that people with moderate or greater hearing loss have approximately twice the odds of psychological distress compared to those without hearing loss. Hearing aid customization that actually works for your life can make the difference between wearing your devices every day and leaving them in a drawer.
We fit every Phonak hearing aid we sell remotely using the same professional customization process traditional clinics use. This guide explains exactly what that process involves, what you can adjust yourself through the myPhonak app, and how customization differs across the Sphere Infinio Ultra, Infinio Ultra R, and Lumity. For a full overview of current Phonak models, our Phonak hearing aid innovations guide covers the complete lineup.
Phonak hearing aid customization happens at two levels: professional programming and user-controlled adjustments. Understanding the difference matters because it shapes realistic expectations for what you can do yourself and when you need our team involved.
Professional programming is what happens in the fitting software that only licensed hearing care providers can access. This is where your audiogram gets translated into a specific gain prescription, where frequency response is shaped to match your hearing profile, where noise reduction aggressiveness is set, where AutoSense OS environment detection thresholds are calibrated, and where directional microphone behavior is configured.
This level of customization cannot be done through the myPhonak app. It requires the manufacturer software, a valid audiogram, and a licensed provider who knows how to interpret both. It is also where most of the meaningful performance difference between a well-fitted and a poorly fitted hearing aid lives.
User-controlled adjustments are everything accessible through the myPhonak app without a fitting session. These include volume changes, three-band EQ adjustments, program switching, and for Sphere Infinio Ultra users, real-time visibility into which AutoSense OS 6.0 environment mode is active. Tap control configuration on the Sphere Infinio Ultra and Lumity L90 also lives here.
User adjustments are valuable for day-to-day fine-tuning. They cannot replace professional programming but they extend it usefully between sessions.
Phonak hearing aid customization starts before your devices ship. You either take our free online hearing test or submit an existing audiogram. Our licensed hearing care providers review your results and use them to select the right Phonak model and technology level for your hearing profile and lifestyle. A buyer who spends significant time in demanding noise environments will be steered toward the Sphere Infinio Ultra's DEEPSONIC processing. Someone primarily in quieter settings who wants reliable performance at a better price point may be a stronger fit for the Lumity L90.
The hearing profile stage also covers practical questions: Do you use iOS or Android? Do you connect to multiple devices? Do you experience tinnitus? Are dexterity or vision considerations relevant to app and control usage? These answers shape both the model selection and the initial programming choices.
Once your model is confirmed and your audiogram is reviewed, our providers program your hearing aids before they ship. Your devices arrive ready to use, not configured to a generic default profile.
Pre-ship programming covers:
Your devices arrive within approximately five business days. Your first remote fitting appointment is where Phonak hearing aid customization becomes a conversation rather than a calculation.
During this session our provider connects to your hearing aids through the telehealth platform and can make real-time changes while you listen and provide feedback. You will typically spend time going through different listening scenarios, adjusting gain at specific frequencies, refining directional microphone sensitivity, and confirming that the overall sound quality matches your expectations. Sessions typically run 20 to 30 minutes.
What gets refined in a first fitting appointment:
Professional customization does not end at the first appointment. The first two to four weeks of wearing new hearing aids reveal things no appointment can predict. Your brain is adapting to sounds it has not processed properly in years. Environments you visit regularly expose the hearing aids to conditions that a 30-minute remote session cannot simulate.
We recommend keeping informal notes during this period. Which environments feel good? Which feel off? Is the overall volume comfortable across the day, or does it feel fatiguing by afternoon? Are there specific situations where speech sounds unclear despite noise levels being manageable? This detail makes your follow-up session significantly more productive.
Every Phonak hearing aid we sell includes unlimited remote adjustments for as long as you own your devices. There is no session cap and no time limit. Follow-up customization sessions are available whenever your hearing or listening environments change, when you notice something the myPhonak app cannot resolve, or simply when you want a professional review of your current settings.
Common reasons for follow-up Phonak hearing aid customization sessions:
The customization framework above applies to all three current Phonak models we carry. The specific options available within that framework differ meaningfully by model.
The Sphere Infinio Ultra runs AutoSense OS 6.0 on a dual-chip DEEPSONIC and ERA architecture. This gives our providers the most granular customization options of any current Phonak model. Spheric Speech Clarity intensity can be fine-tuned within fitting software. StereoZoom 2.0 directional behavior can be calibrated for specific use cases. The full AutoSense OS 6.0 environment library, covering more detected scenarios than OS 5.0, gives more targets for environment-specific programming.
Through the myPhonak app, Sphere Infinio Ultra users get real-time visibility into which AutoSense OS 6.0 mode is active, full EQ access, tap control configuration, and the complete health tracking dashboard. This is the most capable self-adjustment platform in the Phonak lineup.
The Infinio Ultra R runs AutoSense OS 6.0 on the ERA chip. Professional customization options are very similar to the Sphere Infinio Ultra, with the exception of Spheric Speech Clarity controls, which are exclusive to the DEEPSONIC chip. The app experience is functionally identical for the features most users access daily: volume, EQ, program switching, tap control, and telehealth access.
The Lumity L90 runs AutoSense OS 5.0. Professional programming options are strong across the full range of standard fitting parameters. The environment detection library is somewhat narrower than OS 6.0, which means slightly fewer environment-specific targets for customization. Tap control is available on the L90 and configurable through the app. The myPhonak telehealth session experience is identical to the Infinio series.

Traditional clinics charge thousands more for the same Phonak hearing aids you see here, require multiple in-person appointments, and often limit the number of adjustments included after your initial fitting. We provide licensed hearing care providers using the same manufacturer software and programming parameters, unlimited remote adjustments, and significant cost savings, all without leaving your home. Bare-bones online sellers ship pre-configured devices with no professional involvement, no licensed fitting, and minimal ongoing support.
The result in practice: a Phonak hearing aid purchased elsewhere and self-programmed via a generic app will underperform the same model professionally fitted to your audiogram by a licensed provider. Customization is where performance is made, not where the device is selected.
Every Phonak hearing aid we sell comes with a 60-day risk-free trial.
The initial programming happens before your devices ship. Your first remote fitting appointment runs approximately 20 to 30 minutes. Most people find the customization process feels substantially complete after two or three sessions over the first four to six weeks, though unlimited adjustments are included indefinitely. Hearing aid fitting is an iterative process, not a single event.
Yes, within the user-adjustment layer. The myPhonak app gives you volume control, three-band EQ adjustments, program switching, and tap control configuration. These are genuinely useful between-session tools. Professional programming at the audiogram and gain prescription level requires our licensed providers and the manufacturer fitting software.
AutoSense OS is Phonak's automatic environment detection platform. It continuously classifies the acoustic environment and adjusts the full processing profile of the hearing aids accordingly, covering scenarios from quiet to speech in noise to music to outdoor settings. Customization of AutoSense OS behavior happens at the professional level: our providers calibrate detection thresholds, noise reduction behavior, and directional microphone response within each environment class. The current Sphere Infinio Ultra and Infinio Ultra R run AutoSense OS 6.0. The Lumity runs AutoSense OS 5.0.
Schedule a remote adjustment session with our team. We will reassess your current programming against your updated hearing profile and make the necessary changes. If a new audiogram indicates a significant shift, we can reprogram your devices to match. Unlimited adjustments cover this scenario.
Yes, professional Phonak hearing aid customization requires an audiogram. You can submit an existing one or take our free online hearing test, which our providers review as part of the fitting process. Our hearing test is designed to generate the information needed for initial programming.
Phonak hearing aid customization done well is not a one-time event. It is a professional process grounded in your specific audiogram, refined through real-world use, and supported by unlimited access to licensed hearing care providers who use the same tools traditional clinics use.
We have been doing this remotely for over 30 years. Every device ships pre-programmed to your profile, and our team is available as your hearing and your life evolve.
