One of the first decisions hearing aid users face is whether to choose a traditional behind-the-ear device that represents the state of the art, or an in-the-ear offering that is more discreet. While discreet designs appeal, many ITE hearing aids historically lag behind BTE models in audio fidelity. Size constraints limit on-board electronics, and placing microphones inside the ear canal can reduce sound capture. Battery life can also suffer in smaller devices. Phonak seeks to narrow this gap with its Virto R Infinio, an advanced ITE option designed to rival larger models in performance.
The Infinio stands out as Phonak’s most sophisticated ITE model to date, primarily because it is offered exclusively with custom-fit ear molds. Audiologists create these molds by filling the patient’s ear canal with a soft material that hardens to form a precise, personalized shell. This bespoke shell positions the receiver as close to the eardrum as possible, potentially maximizing amplification and sound quality.
Design and Fitting Process
The Infinio is delivered in two basic designs, one open and one closed. The open design features a vented channel that allows a small amount of ambient sound to enter the ear canal, while the closed design provides a full seal similar to an earplug. In practice, the open design offers a balance between amplification and environmental awareness, whereas the closed design may enhance isolation for streaming use or in very quiet environments. A user may prefer open for everyday listening and closed for focused listening or streaming sessions.
In practice, the units fit snugly and resemble earplugs more than traditional earbuds, with a minimal external profile and a small retrieval wire. Operation relies on a single exterior control button used to power the device and manage calls via Bluetooth. All other settings, including volume adjustments and program selections, are managed through the myPhonak mobile app. A two-appointment fitting process is typical: one for initial molding and another to tune the devices after production, usually about a week later.
Sound Quality and Performance
The Virto R Infinio incorporates Phonak’s latest processor and software. In testing, overall sound quality was strong and notably improved for an ITE design, though performance did not fully reach top-tier BTE models from some competitors. Environmental programs are available, with most settings maintained in Automatic mode for best balance. Users reported generally clean amplification with quiet feedback and low self-noise, though some high-frequency artifacts can appear at high volumes.
Bluetooth streaming quality is solid, with audible bass prominence relative to many hearing aids. However, while streaming performance is good, noise cancellation does not match high-end earbuds, so the Infinio is not ideal for music listening in very noisy environments. A built-in hearing-aid locator via the myPhonak app helps locate devices if misplaced.
Battery Life and Charging
Phonak reports a maximum battery life of around 30 hours (without Bluetooth streaming). Real-world use in tests typically yielded about 23 hours of use between charges. The charging case provides magnetic attachments for the aids, but its full functionality depends on being plugged into a USB-C charger. Users should plan for overnight charging and consider carrying a charger for longer trips, as extended periods away from power can strain usage for heavy users.
Battery drain can occur even when the devices are not in use, a factor to consider for travelers and weekend road trips. The case design itself is notably large, with elegant magnetic fittings but no onboard battery—limiting portability if charging opportunities are scarce.
Fit, Comfort, and Practical Considerations
A key advantage of the Virto R Infinio is comfort. The devices are lightweight (about 2.28 grams per ear) and designed to be worn for extended periods without irritation. The fit is highly personalized due to the custom molds, which helps with both comfort and retention. The absence of a protruding stem reduces the chance of snagging on hair or clothing, contributing to a low-profile appearance.
Customization remains essential. The Infinio uses a single-power button for basic controls, while more advanced settings require the companion app or in-office tuning by an audiologist. The two-visit fitting process ensures precise calibration to an individual’s hearing profile and ear geometry.
Pricing and Availability
The Virto R Infinio is a prescription product requiring an audiologist fit. Phonak lists a typical price around $4,000, reflecting the bespoke molding and premium build. While this places it above many OTC options, the product aims to deliver enhanced fidelity, comfort, and personalization that some users prioritize over cost.
Strengths and Limitations
- Strengths: Custom-fit comfort and retention; close-to-ear receiver positioning; solid Bluetooth streaming; discreet, plug-style form factor; robust app-based adjustments.
- Limitations: Not always matching top BTE performance; high-frequency artifacts can appear at higher volumes; charging case requires USB-C power; price point may be a barrier for some users.
Bottom Line
For patients prioritizing discretion and a highly personalized fit, the Phonak Virto R Infinio represents a strong option within the ITE category. Its custom molds and refined sound processing help bring ITE performance closer to BTE standards, with the trade-offs of higher cost and continued reliance on professional fitting. If budget permits and a discreet design is a key requirement, the Infinio merits consideration.
