Phonak Hearing Aids: Costs, Reviews, and Sound Samples

Phonak is the top global hearing aid brand by sales volume and a leader in speech-in-noise, wireless connectivity, and rechargeable technology. The Phonak brand is part of the Switzerland-based Sonova Group and offers a wide range of quality hearing aids for people with mild to profound hearing loss, with products that cover almost any lifestyle.

Phonak’s newest Audéo EON family builds on the dual-chip technology introduced with Infinio Sphere. The flagship EON Sphere combines a dedicated Hypersonic AI processor for speech enhancement with Phonak’s ERA connectivity chip. Phonak says the redesigned Sphere is 25% smaller and 20% lighter than the previous generation, while adding more adaptive automatic processing, WindBlock 2.0, and Auracast broadcast audio. For buyers who wanted Sphere’s speech-in-noise technology but found the original too bulky, EON deserves a fresh look.

Over the last 10+ years, HearingTracker has reviewed over 25 Phonak product families. While many of the reviews are now archived, you'll find a number of recent reviews using the links above.

Phonak Hearing Aid Models

Phonak makes premium prescription hearing aids, which are programmed by an audiologist or other hearing care provider based on the results of your hearing test. The company has a broad range of hearing aid models addressing all levels of hearing loss. They come in multiple form factors, with advanced Bluetooth and other connectivity features and a variety of accessories.

Latest Flagships: Phonak Audéo EON Sphere and EON R

Phonak’s flagship Audéo EON family, launched in the US in August 2026, refines the previous Infinio Sphere Ultra concept in several important ways: it features a smaller and lighter design, more consistent automatic switching, improved wind management, and Auracast connectivity. With the Sphere model, it also brings Spheric Speech Clarity to the Standard 50 technology level, expanding access beyond the top two tiers.

EON Sphere versus EON R. The rechargeable Audéo EON Sphere uses two sound processors: the ERA chip for connectivity and key functions (see below), and the HYPERSONIC chip for Spheric Speech Clarity 3.0, which separates speech from background noise in real time using deep neural networks (DNNs).

In contrast, Audéo EON R is a conventional rechargeable RIC that uses only the ERA chip, but shares AutoSense OS AI 8.0 and WindBlock 2.0. In other words, it lacks Sphere’s dedicated HYPERSONIC AI-driven speech-separation processor.

More consistent automatic adjustments. AutoSense OS AI 8.0 analyzes the listening environment and adjusts the hearing aids as conditions change. A key goal is to keep Sphere processing engaged more consistently when a noisy setting briefly becomes quieter. Your hearing care provider can fine-tune the automatic programs around your needs and preferences.

Updated fitting approach. EON also introduces Adaptive Phonak Digital 4.0 (APD 4.0), Phonak’s proprietary fitting formula. The company says it is designed to maintain sound fidelity as listening environments change. Your provider still needs to tailor amplification to your hearing and check the resulting fit.

Bluetooth, Roger, and Auracast. EON retains Phonak’s broad Bluetooth compatibility—arguably the broadest in the hearing aid industry—with phones, tablets, and computers, including hands-free calls using the hearing aid microphones. It can remember eight paired Bluetooth devices, with two connected simultaneously. RogerDirect supports compatible Roger microphones, while Auracast adds access to broadcasts at equipped venues through the myPhonak app. The benefit depends on broadcasts being available where you go (Auracast is relatively new and just starting to catch on.) EON has no built-in telecoil—a consideration for people who regularly use hearing loops.

Battery life and charging. Phonak rates EON at up to 38 hours per charge; a more demanding manufacturer scenario, including 8 hours of streaming and time in noise, gives approximately 22 hours. (Note that these are manufacturer estimates, with runtime varying by use and the age of the hearing aid.) A full recharge takes about 2.5 hours. The cable-powered Charger RIC E needs an external power source; the portable ChargerGo RIC I E has a built-in battery for charging away from an outlet.

WindBlock 2.0 for outdoor listening. Wind blowing across hearing aid microphones can create a buffeting sound that often overwhelms conversation. WindBlock 2.0 compares the microphones and favors the cleaner signal, aiming to reduce that disturbance while preserving speech and surrounding sounds. Matthew considers it a potentially valuable improvement for walkers, cyclists, runners, and anyone frustrated by wind or an open car window.

What our testing found. Dr. Steve Taddei’s EON Sphere 90 review (see YouTube video below) reports a HearAdvisor SoundScore of 5.0/5 with an A SoundGrade; the overall HearingTracker score is 4.6/5. Professionally tuned speech results were nearly identical to Sphere Ultra’s. He found the smaller housing more comfortable, but competing voices could still interfere with the person you’re trying to listen to, and streaming-balance settings sometimes failed to stay put. (These findings apply to the tested Sphere 90 configuration, rather than separate tests of EON R or the lower technology levels.)

This propels EON into the ranks of some of the best Bluetooth and best in background noise hearing aids available.

Phonak Audéo EON is IP68 rated, the highest waterproof and dust-proof rating available for hearing aids, and comes in 8 colors including the new Sienna Red. The others are Sand Beige, Sandalwood, Chestnut, Champagne, Silver Gray, Graphite Gray, and Velvet Black.

Who should consider EON? EON Sphere is particularly worth a try if background noise is a major frustration, the earlier Sphere felt too large, or you value its combination of outdoor features and connectivity. We think a comfortable, satisfied Sphere Ultra wearer has less reason to replace their hearing aids solely for improved hearing aid performance.

Previous Generations: Audéo Infinio (Ultra) Sphere and Infinio R

Infinio Ultra is the preceding Audéo generation. Launched in the United States in November 2025, the larger Ultra Sphere model uses both the ERA and DEEPSONIC chips (EON Sphere replaces DEEPSONIC with the new HYPERSONIC chip), while the Infinio R model uses just the ER chip. The Ultra update improved the performance and battery life of both models through new firmware, whereas EON improved performance through new hardware.

Although EON is now the company’s flagship model, Infinio Ultra is still a very good hearing aid. Both Steve and Matthew suggest that new hearing aid buyers considering Infinio models should compare their complete price and care package with EON, and existing owners of Infinio Ultra should discuss comfort, listening needs, and model-specific connectivity updates with their hearing care professional before replacing them with EON.

Audéo Infinio (Ultra) Sphere R

Phonak Infinio product portfolio is the rechargeable Audéo Sphere Infinio R receiver-in-canal (RIC) hearing aid, which was the industry’s first dual-chip hearing aid with a dedicated AI-powered denoising chip called DEEPSONIC. Sphere Infinio runs on both the ERA chip and the DEEPSONIC chip that has a Deep Neural Network (DNN) trained on 22 million sound samples. This means it allows real-time audio processing while denoising the speech stream, effectively separating speech from noise, and reportedly yielding an unprecedented 10 dB Signal-to-Noise (SNR) improvement.

Phonak Audéo Infinio (Ultra) Sphere is still among the best waterproof and best overall hearing aids available. In HearAdvisor testing, Sphere Infinio is still in the top-5 for SoundScore (4.9 out of 5), earning it an “A” SoundGrade.

Additionally, Phonak has finally added a “Find My Hearing Aid” feature to the myPhonak app to help you locate your missing hearing aids if you lose or misplace them. The Audéo RIC models come in two tech tiers (70 and 90) and 8 different colors.

Audéo Infinio (Ultra) R

Although it may be slightly overshadowed by the unique Audéo Infinio Ultra Sphere, the rechargeable Audéo Infinio Ultra R, with the ERA chip platform, is also very impressive, even if it lacks the AI-related buzzwords of the DEEPSONIC chip. Those looking for a smaller RIC hearing aid with better battery life should consider the Infinio R, but just be aware that you will be compromising a little on performance in background noise.

The ERA chip delivers important features and enhancements:

The ERA chip can be thought of as the workhorse of all EON and Infinio (Ultra) hearing aids, directing the sound processing and connectivity functions, including these key functions:

• Enhanced connectivity and greater stability - The ERA chip can shift between streaming and acoustic input without missing conversations and provides impressive distance for transmitting audio from a smartphone to the aids.
• Exceptional sound quality - Phonak’s new APD 3.0 algorithm in its fitting software now uses Harman Curves (a tool typically found in headphones and loudspeakers) for finding the most natural and pleasing sound experience
• Smarter processing - Using AI, AutoSense OS with SmartSpeech technology identifies your speech environment then reportedly helps improve speech understanding by 16% and reduce listening effort by 45%
• New personalization features - New AI Dome Proposer for better RIC fittings from the get-to and an acoustically optimized vent that opens and closes depending on the listening situation

Features shared by EON, Infinio, and Lumity:

• Stereo Bluetooth streaming - Streaming from iPhone, iPad, MacOS, Android, Windows, and any other Bluetooth-enabled audio device; it can pair with up to 8 Bluetooth devices and has 2 active Bluetooth connections
• Hands-free calling in stereo - True hands-free calling from Bluetooth-enabled phones and VOIP services like Skype
• Clearer speech in quiet settings - StereoZoom 2.0 and SpeechSensor deliver clearer speech in background noise
• Tap controls - You can double-tap the hearing aids to accept/end phone calls, pause/result streaming, and access voice assistants like Siri, Alexa, and Google Assistant
• Motion sensing - An ultra-low power accelerometer detects when you move and adjusts the hearing aid microphones and noise cancellation settings
• Health tracking - If using the myPhonak app, you’ll be able to track steps, distances walked or run, heart rate, activity levels, and hearing aid wear times
• Improved noise cancellation - First introduced in Phonak’s Paradise line, “Dynamic Noise Cancellation” is an automated spatial noise cancellation system that works in combination with the directional beamformer microphones
• TV Streaming - Can stream directly from Bluetooth-enabled TVs, and can also stream from the Phonak TV Connector accessory
• Rechargeability - Hearing aids provide full day of hearing aid use from a single charge
• At-home adjustments - Hearing aids can be adjusted remotely by your hearing care provider
• Moisture protection - IP68 rating for resistance to moisture and dust/dirt is the best possible for hearing aids.
• RogerDirect - Users can stream audio from Phonak’s portable Roger remote microphone directly to their hearing aids
• Smartphone app - The MyPhonak app provides access to remote support services enabling your hearing care professional to customize your personal listening experience in real-time
• ActiveVent - A tiny mechanical receiver vent system that can open or close depending on the listening situation (see below for details).

For Single-sided Hearing: CROS Infinio

The Phonak CROS Infinio offers a practical solution for individuals with unaidable hearing loss in one ear. Paired with Audéo Infinio R or Infinio Ultra R, it provides sound by wirelessly transmitting audio from the non-hearing side to the functional ear, making it easier to engage in conversations and navigate daily environments. Designed with durability in mind, Phonak CROS is built to handle the wear and tear of everyday life, and its fully rechargeable battery ensures reliable, all-day performance.

CROS Infinio offers universal Bluetooth connectivity for seamless integration with smartphones, tablets, and other devices. It incorporates the new ERA chip, giving it improved sound processing and stable wireless connections, enhancing speech clarity and hands-free communication. Keep in mind that CROS Infinio is not compatible with Infinio Sphere.

Discreet Options: Virto Infinio

Phonak Virto R Infinio, introduced in August 2025, is designed to deliver full-featured RIC-level performance in a rechargeable custom in-the-ear (ITE) device. This hearing aid compresses the company’s impressive Infinio platform technology and ERA chip into a sleek, discreet form factor with a high-tech look and universal connectivity for Apple and Android devices. Virto R Infinio is the smallest rechargeable ITE Phonak has ever made—and one of the tiniest on the market.

Virto CIC and Titanium IIC/CIC

The Phonak Virto Infinio is a custom in-ear hearing aid line powered by Phonak’s new ERA chip, offering top-tier sound quality, seamless adaptability to different environments, and personalized fitting for optimal comfort. It is available in either a completely-in-canal (CIC) or invisible-in-canal (IIC) form factor.

Phonak also offers the non-wireless Virto 10 NW O. Combined with the ultra-durable Virto Titanium CIC/IIC, this lineup is ideal for those seeking discreet, high-performance solutions for mild to severe hearing loss. While both models lack wireless connectivity and rechargeable options, Virto Infinio excels in delivering clear, natural sound and a nearly invisible aesthetic.

Invisible Hearing Aid: Phonak Lyric

Placed completely out of sight in your ear canal near the eardrum by a trained professional, the Phonak Lyric 4 is an invisible hearing aid that is the hearing healthcare's only 24/7, disposable hearing aid sold on a subscription-type plan. It’s a worn round the clock for several months at a time through daily activities including exercise and showering. While traditional hearing aids capture and process sound outside of the ear, Lyric uses the natural anatomy of the ear to amplify and provide a full, natural listening experience.

HearingTracker Audiologist Matthew Allsop provides an update on the latest features and benefits of Phonak Lyric.

Phonak Lumity

Although the spotlight has now been taken over by EON and Infinio Ultra, Phonak’s previous Lumity hearing aid line retains its status as a great performer. In fact, we’ve listed it above as sharing many of the key features you'll find in EON and Infinio: universal Bluetooth audio streaming and hands-free calling from most Bluetooth-capable devices, speech in noise enhancement, noise cancelation, motion sensors, tap controls, AI sound scene identification (AutoSense 5.0), and more.

Budget Option: Audéo Lumity

Audéo Lumity, now superseded by Infinio, is still available to purchase in four Receiver-in-Canal (RIC) form factors, all of which are rechargeable. Lumity R is a rechargeable receiver-in-canal model that comes in a variety of colors from velvet black to sand beige. Lumity RT is similar to R, but adds a telecoil. And Lumity Life is like the R model (no telecoil) but adds much better water resistance—great for those who live in a more humid environment or have a more active lifestyle.

The fourth form factor, Lumity Slim, was designed to look more like a high-tech communication device than a hearing aid, with a distinct left and right design for a contoured fit behind the ear, even for those who wear glasses.

Phonak Lumity received an "A" SoundScore in HearAdvisor's independent lab testing, and was recognized by the lab as a 2023 Expert Choice Award Winner.

For Severe to Profound Hearing Loss: Naída Lumity BTE Models

Naída Lumity is the Behind-the-Ear (BTE) hearing aid Phonak designed for a wider variety of hearing needs. Naída Lumity L-PR is a versatile rechargeable BTE, Naída L-SP is a super-power device with a disposable size 13 battery, and Naída L-UP is an ultra-power device with a disposable size 675 battery designed particularly for people with severe to profound hearing loss. Both contain the best advanced Lumity features, although there are some differences. The rechargeable Naída L-PR comes with a motion sensor and tap controls, while the battery-powered L-SP and L-UP models do not; however, both the L-SP and L-UP include a telecoil, while the L-PR does not.

For Kids: Sky Lumity

Phonak also offers Sky Lumity for pediatric hearing loss. These hearing aids feature enhanced connectivity, enabling children to connect with and explore the digital world. Sky L hearing aids are designed to work seamlessly with myPhonak Junior—the only dedicated pediatric app—giving kids control over their hearing aids and lending a sense of ownership and personal connection to their devices. Parents can also utilize the app to monitor wearing time, schedule remote consultations with hearing providers, and set parental controls.

Phonak Hearing Aid Prices

Phonak prices depend on the model, technology level, provider, and care included. Compare the full package—not just the hearing aids—including fitting, follow-up adjustments, trial period, warranty, and ongoing support. EON Sphere’s dedicated speech-separation technology is available at Premium 90, Advanced 70, and Standard 50, giving buyers more options at different price points. See our EON product page for current offers and the services included with each.

Phonak ActiveVent

Phonak offers a unique receiver venting system called ActiveVent. While not for everyone, ActiveVent is an optional system designed to give hearing aid wearers some of the comfort and natural sound of an open-fit hearing aid, while still allowing the device to behave more like a closed-fit hearing aid when extra performance is needed. It's available for compatible Phonak rechargeable RIC hearing aids, including recent Phonak platforms such as Lumity and Infinio.

Standard earmolds generally have a fixed vent that allows natural sound to pass through and mix with the amplified sound. ActiveVent has a tiny mechanical vent that automatically opens or closes depending on the listening situation. In quieter environments, it can stay open to reduce the plugged-up feeling, preserve more natural own-voice sound, and maintain environmental awareness. In noise or while streaming, it can close to help Phonak’s directional microphones and noise-reduction features work more effectively and to provide fuller streamed sound.

ActiveVent may be especially appealing for people with mild-to-moderate hearing loss who like the comfort of an open fit but want better performance in noise; however, it may not be ideal for every wearer, including those who need more powerful amplification, prefer a simpler receiver/dome setup, or are not comfortable with the added cleaning and maintenance requirements.

In the video below, Matthew Allsop explains the pros, limitations, and real-world considerations of Phonak’s ActiveVent system.

Hearing Aid Accessories

Phonak provides a number of hearing aid accessories that improve hearing aid performance in challenging listening environments, while watching TV, when on the phone, and in numerous other ways. To learn which accessories work with the Phonak hearing aids you wear, consult with your hearing healthcare provider.

Accessories: Auracast, TV Connector, myPhonak app, PartnerMic™ and RemoteControl

EON adds Auracast broadcast listening to Phonak’s existing Bluetooth and Roger options. The myPhonak app can scan for available broadcasts, allowing users to find compatible audio at equipped venues. Before relying on Auracast for a particular event, check that a broadcast will be available and that your hearing aids and phone support the required connection method.

Unless otherwise noted, all Eon (E), Infinio (I), Lumity (L) family hearing aids are compatible with the TV Connector, myPhonak app, PartnerMic™ and RemoteControl. In the Costco world (which includes the Sennheiser Sonite Rise from Phonak's parent company, Sonova), the PartnerMic™ is referred to as PartnerMic Easy Line, and RemoteControl is referred to as Remote Control Easy Line.

Roger On Sphere: AI Speech Enhancement Beyond the Hearing Aids

Even advanced hearing aids can struggle with conversations across a table, competing noise, or a speaker at a distance. Phonak’s Roger On Sphere brings dedicated AI speech separation to a remote microphone, providing another option for these challenging situations.

Its RogerSense OS uses a DNN technology—similar to Sphere—to separate speech from background noise before transmitting audio wirelessly to compatible hearing aids or cochlear implants. The microphone automatically adjusts to different listening situations, including meetings, lectures, car rides, and social gatherings.

Phonak reports an additional 3 dB signal-to-noise (SNR) ratio benefit over the previous Roger On model.

Despite the Sphere name, the accessory is not limited to Audéo EON Sphere hearing aids; Roger supports a broad range of hearing devices; your provider can confirm the receiver or connection needed for your particular model.

Announced in October 2026, Roger On Sphere is scheduled to reach most markets in mid-November 2026. Ask your hearing care provider about availability and an in-clinic demonstration.

Other Roger Accessories

Phonak offers a strong portfolio of wireless accessories and apps. The wireless Roger portfolio is particularly innovative, with devices like the Roger Table Mic II being standouts in the industry. Multiple Table Mics can be connected to create a network and with a range of more than 20 meters (65 ft). Here are some of our favorites:

Chargers for Phonak Rechargeable Hearing Aids

Phonak offers model-specific chargers, including desktop options and portable cases with built-in batteries. Audéo EON R and EON Sphere use the cable-powered Charger RIC E or portable ChargerGo RIC I E, which provides up to 3 full recharges away from an outlet; both recharge the hearing aids in approximately 2.5 hours. 

Audéo Infinio and Infinio Ultra R use the Charger RIC I or portable ChargerGo RIC I, while Infinio Sphere and Sphere Ultra require the separate ChargerGo RIC SPH I. For Virto R Infinio, Phonak offers the desktop Charger Virto I and portable ChargerGo ITE, which provides up to 3 full recharges away from an outlet.

Phonak is Sonova Group’s flagship brand, known not only as a market leader but also as an innovator in digital hearing aid products and technologies. In 2017, Phonak was the first to deliver lithium-ion rechargeable hearing aids with all-day power. And in 2018, they delivered the first hearing aid with truly universal Bluetooth connectivity. And in 2024, they were the first to introduce a dedicated AI chip for speech-in-noise enhancement.
