Oticon Intent vs. Phonak Infinio: Charlotte Audiologist's Analysis

July 11, 2025

When it comes to selecting the right hearing aids, Charlotte residents often find themselves weighing the latest innovations from leading manufacturers. Two premium hearing aids that frequently come up in our consultations are the Oticon Intent and the Phonak Infinio. Both represent significant technological advances, but each takes a different approach to addressing hearing loss challenges.

Design and Comfort: First Impressions Matter

The Oticon Intent introduces a completely redesigned exterior, making it Oticon's smallest Bluetooth receiver-in-canal hearing aid to date. Despite being slightly bulkier than previous models, the Intent maintains a discreet profile and comes in nine matte colors, including a distinctive sky blue option. The design prioritizes simplicity with a single-button interface, moving away from the traditional rocker switch.

The Phonak Infinio series maintains the familiar aesthetic of previous Phonak models but with subtle improvements. The Audéo Infinio R measures 31.9 x 14.0 x 9.5 mm and weighs just 3.0 grams, while the premium Audéo Infinio Sphere is even more compact at 28.8 x 12.4 x 8.7 mm. Both models feature dual-port microphones and an updated rocker switch positioned for easier access. For those preferring gesture controls, tap functionality is available on higher-tier models.

Technology Foundations: Different Philosophies

The Oticon Intent runs on the new Sirius chip, powering advanced features like Deep Neural Network 2.0 (DNN 2.0) and MoreSound Intelligence 3.0. This technology was trained on over 12 million sound inputs to help the hearing aid process speech and noise more naturally. The system provides up to 12-decibel noise suppression while maintaining access to the full sound environment.

Phonak takes a dual-chip approach with their premium Infinio Sphere model. The ERA chip handles core sound processing and connectivity, while the dedicated DEEPSONIC chip focuses exclusively on real-time AI processing for speech-in-noise separation. This DEEPSONIC chip performs 7,700 million operations per second and was trained on 22 million sound samples across multiple languages.

Speech Understanding: The Core Challenge

Both manufacturers recognize that understanding speech in noisy environments remains the biggest challenge for people with hearing loss, but they address it differently.

The Oticon Intent features 4D Sensor technology, which monitors conversation activity, head movement, body movement, and acoustic environment. This data helps the hearing aid adapt its response based on the user's listening intentions. When you turn your head toward someone speaking, the Intent recognizes this movement and adjusts accordingly. Oticon claims this technology can enhance speech comprehension by 15% in dynamic environments like restaurants.

Phonak's Spheric Speech Clarity system, available on the Infinio Sphere model, uses deep neural network processing to separate speech from background noise in real-time. The company reports up to 10 dB improvement in signal-to-noise ratio, with clinical studies showing 93% of users prefer the first-fit performance compared to leading competitors. The system maintains speech signal integrity while actively removing unwanted background sounds.

Connectivity and Modern Features

Both hearing aids embrace the latest Bluetooth technologies, but with different implementations. The Oticon Intent supports Bluetooth LE audio and is Auracast-ready, promising future compatibility with public venue audio systems. It provides direct streaming and hands-free communication with iOS devices (iPhone 11 or later) and compatible Android phones. The Intent also includes a built-in telecoil for use with hearing loop systems.

The Phonak Infinio series offers universal Bluetooth compatibility, supporting both Bluetooth LE and older Bluetooth Classic protocols. Phonak reports that their new chip increases transmission power sixfold, ensuring stable connections over longer distances. Like the Intent, Infinio models are Auracast-ready and support hands-free calling across multiple device types.

Battery Performance and Charging

Battery life represents a practical consideration for daily use. The Oticon Intent provides up to 20 hours of use on a full charge, with quick charging options available. A 15-minute charge delivers 4 hours of use, while 30 minutes provides 8 hours. The Intent requires only 2 hours for a complete charge.

Phonak Infinio models offer 16-18 hours of use on a full charge. The standard Audéo Infinio R charges completely in 3 hours, while the Sphere model requires 3.5 hours. Both provide quick-charge options, with 15 minutes yielding up to 3 hours of use. Multiple charger options are available, including portable models with built-in power banks.

Durability and Protection

Both manufacturers prioritize durability for active lifestyles. The Oticon Intent carries an IP68 rating, making it highly resistant to water and dust. The Phonak Infinio series also features IP68 protection and has undergone over 135 individual durability tests. Phonak incorporated additional protective measures like silicon-sealed seams and parylene coating, drawing from their Life model's robust design standards.

Customization and Fitting Options

The Oticon Intent accommodates mild to profound hearing losses with interchangeable receivers and four technology levels (Intent 1 through Intent 4). The hearing aid offers various acoustic coupling options, from soft domes to custom-made shells.

Phonak Infinio provides similar flexibility with receiver options for mild to profound hearing loss. The series includes four performance levels (I30, I50, I70, I90) and multiple acoustic coupling choices. Active vent receivers are compatible with Infinio models, potentially enhancing sound quality for appropriate candidates.

Real-World Performance in Charlotte

In our Charlotte practice, we've observed that both hearing aids perform exceptionally well, but patient preferences often align with their specific lifestyle needs and listening priorities. The Oticon Intent appeals to users who value natural sound processing and prefer technology that adapts to their behavior patterns. The 4D sensor technology particularly benefits active individuals who frequently change environments throughout their day.

The Phonak Infinio Sphere attracts patients who prioritize maximum speech clarity in challenging listening situations. The dedicated AI processing chip delivers impressive noise reduction capabilities, making it particularly suitable for individuals who regularly attend social gatherings, business meetings, or other speech-focused activities.

Professional Fitting Makes the Difference

Regardless of which technology you choose, proper fitting and verification remain essential for optimal performance. We use Real Ear Measurements to ensure that your hearing aids are precisely programmed to match your specific hearing loss and ear canal acoustics. This verification process helps maximize the benefits of either the Intent's environmental adaptation or the Infinio's AI-powered speech processing.

Both manufacturers provide comprehensive fitting software that allows us to fine-tune performance based on your feedback and real-world experiences. Regular follow-up appointments help ensure your hearing aids continue to meet your evolving needs.

Making Your Decision in Charlotte

The choice between Oticon Intent and Phonak Infinio ultimately depends on your individual hearing loss pattern, lifestyle demands, and personal preferences. Some patients prefer the Intent's natural sound philosophy and behavioral adaptation, while others benefit more from the Infinio's aggressive noise reduction and speech enhancement.

During your consultation, we can demonstrate both technologies and help you experience the differences firsthand. We'll consider factors like your typical listening environments, technology comfort level, and specific communication challenges to guide your decision.
