Our experience with Starkey Genesis AI

Who may like Starkey Genesis AI: Those looking for top-of-the-line hearing aids with advanced AI technology and wellness tracking.

Who may want to avoid Starkey Genesis AI: People seeking a more affordable or over-the-counter (OTC) hearing solution without the need for extensive AI or wellness features.

Insights from our Starkey Genesis testers 

Introduced in 2023, the Starkey Genesis AI line combines great sound quality with advanced features. Our testers say the Genesis AI offers comfort (it was lightweight and secure in the ear) and good performance in five models (IIC, CIC, ITC, ITE, and RIC). The AI-driven sound processing is designed to reduce listening effort, even in noisy environments. We appreciate the advanced technology, including the wellness features, like fall detection and health tracking, with one of our testers dubbing this a “lifestyle hearing aid.”

A standout feature across all models is the Starkey neuro processor, powered by deep neural network (DNN), which is a software that mimics the brain’s natural ability to filter conversations from background noise. This allows users to experience more true-to-life sound quality, even in challenging environments like crowded restaurants or outdoor gatherings.

Genesis AI is also good at managing feedback by reducing whistling and unwanted background noise. Advanced tinnitus technology can help mask ringing or buzzing in the ears for those dealing with tinnitus Tinnitus is when a person hears ringing, buzzing, or other noises in the ear. It is often associated with hearing loss. . We also like that the wireless connectivity allows for hands-free calls, music streaming, and personalized setting adjustments through the app. 

This line’s rechargeable batteries are impressive—the RIC model provides up to 51 hours of battery life on a single charge, making it one of the longest-lasting rechargeable hearing aids available. For smaller styles like the CIC and IIC models, disposable batteries are necessary due to size constraints.

The My Starkey app’s exercise monitoring, step tracking, fall detection, and speech translation make these hearing aids wellness tools as well. Caregivers can use the Hear Share app to monitor care recipients, while Starkey’s TeleHear feature allows users to remotely adjust their hearing aids by connecting with a hearing care professional through video chat. Additional features such as reminders, Edge Mode+ for noisy settings (activated through the app or by tapping your hearing aid), and a customizable voice-activated Smart Assistant (which allows you to speak into the app and adjust settings, set reminders, and ask hearing aid questions) make these some of the most feature-packed devices we’ve seen.

From our tester

“The app is very easy to navigate considering how much it can do. The activity tracking and the ability to add goals, fall alerts, and Hear Share (caregiver network) are excellent. I also like the Find My Hearing Aids feature and appreciate that the Genesis AI translates up to 77 languages.”

The added wellness features, like fall detection and social engagement tracking, make it a versatile choice for those looking to improve both their hearing and overall health.

Who may like Starkey Evolv AI: Those who want a comprehensive hearing aid that not only enhances sound but also tracks wellness and activity.

Who may want to avoid Starkey Evolv AI: People who need the highest level of processing power and the latest AI features.

Insights from our Starkey Evolv AI testers 

The Starkey Evolv AI line was introduced in 2021 and offers a range of hearing aids with advanced AI technology. Offering up to 55 million personalized adjustments every hour, the Evolv AI works to reduce background noise, making conversations easy and more natural. Available in all styles, including a BTE option (which is not available in the Genesis line), these hearing aids are designed for people who want both high-performance hearing and wellness tracking. 

This line of hearing aids is designed to deliver 40 percent more noise reduction than previous models, which can improve your listening experience in challenging environments like cars or crowded spaces. Key features include Edge Mode, which provides real-time adjustments to help you hear better in noisy settings, and “2-Way Audio” for hands-free calling on iPhone devices.

Our experience with Starkey Signature Series

The Starkey Signature Series is a good fit for users who prioritize subtlety and comfort. However, the lack of streaming and Bluetooth options may be a drawback for some. 

Who may like Starkey Signature Series: People seeking a discreet hearing aid solution with the option for a rechargeable CIC model.

Who may want to avoid Starkey Signature Series: Those who prioritize Bluetooth streaming or want longer battery life.

Insights from our Starkey Signature Series testers 

The Starkey Signature Series is the latest addition to the company’s hearing aid lineup, released in March 2024 and offering three models: a rechargeable CIC, a disposable battery CIC, and a disposable battery IIC. This line is the next evolution of Starkey’s technology, focusing on smaller, more discreet hearing aids. Like the other Starkey lines, the Signature Series has advanced AI features, making it a versatile choice for people looking for a compact yet powerful solution to their hearing needs.

One of the Signature Series’ standout features is its tiny, nearly invisible size, custom-molded to your ear canal. Usually, such small devices compromise on battery power, but the rechargeable CIC model offers a 38-hour battery life and a waterproof shell.

Though these smaller models do not support Bluetooth or streaming, they still offer feedback management and natural sound processing. The IIC model, in particular, is nearly invisible when worn, making it ideal for users who prioritize discretion.

How much does Starkey cost? 

Starkey hearing aids are in the premium category, with prices typically ranging between $2,800–$5,000 per pair, depending on the model, technology level, and supplier.

From our expert

Ruth Reisman, an audiologist and hearing aid dispenser in New York, Florida, and Bermuda, told us that in her experience, some Starkey models can cost as much as $8,000.

The Signature Series line is on the higher end of this spectrum because it comes in such a small size. For comparison, other prescription brands like Phonak or Widex also offer devices in the same range, while higher-end OTC devices like Jabra Enhance or Eargo cost around $800–$3,000 per pair.  

Is Starkey covered by insurance?

Insurance coverage for Starkey hearing aids can vary based on your provider and plan. Private health insurance companies sometimes offer partial coverage for hearing aids, but many don’t cover the entire cost. Medicare A and B do not cover hearing aids or fittings, but Medicare Advantage plans may provide some assistance. Medicaid may provide coverage in some states, particularly for those with low-income or severe hearing impairments. It’s always best to check with your insurance provider to understand what’s included in your plan and ask your hearing care provider about possible insurance billing.

How to save money on Starkey

Although Starkey hearing aids are a premium investment, there are ways to manage costs. Many hearing aid providers offer financing plans, allowing you to break up the total cost into monthly payments. Additionally, Starkey has a public commitment division called Starkey Cares, with a Neighbors in Need program, which aims to get devices to those in need. You can also ask your hearing care provider if they offer discounts or promotions, especially for veterans or older adults. Some nonprofit organizations, like the Hearing Loss Association of America, also offer financial assistance for those in need. For those looking to save further, you may want to consider refurbished models or previous-generation devices like the Livio, which offers many similar features at a lower price.

Starkey smartphone apps

Starkey offers five smartphone apps compatible with the Genesis AI and Evolve AI lines.

My Starkey

Starkey offers the My Starkey app, which allows users to control and customize their hearing aids directly from their smartphones. The app is compatible with iOS and Android devices and allows users to adjust volume, switch between personalized programs, or monitor their overall health and activity.

With My Starkey, users can access features like Edge Mode+, which optimizes sound in noisy environments, and “2-Way Audio” for hands-free calling on iPhones. The app also offers remote control capabilities so you can adjust your hearing aid settings without visiting a hearing care professional. For those with health monitoring needs, the app tracks steps, standing time, exercise, and even fall detection, making it a useful tool for older adults or people with mobility issues. Additionally, the reminders, translation functions, and TeleHear for virtual appointments with your hearing care professional offer added convenience for daily life. 

Thrive

The Thrive app was created for the Evolve AI line and functions similarly to the My Starkey app. It allows users to adjust volume, switch modes, and manage other hearing aid features that were previously only accessible through an office visit. It is designed to be easy to set up and navigate.

Key features of the Thrive app include engagement and activity tracking, which monitor physical activity and social interactions. The app also provides assistive tools like Find My Phone, Translate, and Transcribe, making it useful for day-to-day tasks. The Self Check feature allows you to monitor hearing aid performance without visiting a hearing care professional.

Hear Share 

The Hear Share app is designed for caregivers and family to monitor and assist Starkey hearing aid users. Through the app, caregivers can track the user’s hearing aid activity, battery status, and important health metrics such as steps taken and fall alerts. This app enhances safety and peace of mind by allowing caregivers to receive notifications if a fall is detected and stay informed about the wearer’s overall well-being. It’s particularly useful for older adults or those who need regular support from family members or caregivers.

Relax

The Relax app provides relief from tinnitus by offering a selection of 12 unique soundscapes designed to help mask and lessen symptoms. In addition to sound therapy, the app offers educational resources about tinnitus. Users can also find nearby hearing professionals who specialize in tinnitus and other hearing-related issues, making it a helpful tool for both managing symptoms and seeking expert care.

SoundCheck Live

The SoundCheck Live app helps users monitor the noise levels in their environment to determine if they are safe or potentially harmful to their hearing. Using a sound level meter, the app provides real-time feedback about surrounding noise and offers insights into how sounds might affect your hearing over time. It also includes tips on protecting your hearing, such as using hearing protection devices and limiting exposure to high noise levels.

What hearing aid style is best for you?

Starkey offers a wide range of hearing aid styles to suit different preferences, levels of hearing loss, and lifestyle needs. Each type has benefits, and selecting the right one depends on comfort, your level of hearing loss, and preferences. Here’s a breakdown of the different hearing aid styles available from Starkey.

Behind-the-ear (BTE)

BTE hearing aids rest behind the ear and are connected to an earmold inside the ear canal by a thin tube. This style is ideal for those with severe to profound hearing loss due to its powerful amplification capabilities. BTE models are generally larger, which makes them easier to handle and maintain, and they tend to offer longer battery life.

Receiver-in-canal (RIC)

RIC hearing aids are similar to BTE models, but instead of an earmold, they use a smaller ear dome A flexible attachment that helps the hearing aid conform to the ear canal. that sits inside the ear canal. Starkey’s Genesis AI RIC models are popular because of their discreet design, sound quality, and rechargeable options. RIC devices are a great option for people with mild to profound hearing loss who want advanced features like Bluetooth streaming and health monitoring because their larger size allows for more powerful batteries and more features.

In-the-ear (ITE)

ITE hearing aids are custom-made to fit the outer portion of your ear. These devices are larger than other in-ear options, which makes them easier to handle and more powerful. Starkey’s Genesis AI and Evolv AI lines offer rechargeable ITE models with full Bluetooth capabilities and advanced AI features. ITE hearing aids are a solid choice for people with mild to severe hearing loss who prefer a single-piece device that fits snugly inside the ear.

In-the-canal (ITC)

ITC hearing aids are slightly smaller than ITE models, fitting partially in the ear canal. These custom-made devices provide a balance between power and discretion, making them a popular choice for people with mild to moderate hearing loss. Starkey offers ITC models with options for both rechargeable and disposable batteries, depending on your needs. Some of these models also support Bluetooth streaming and app-based controls.

Completely-in-canal (CIC)

CIC hearing aids are designed to fit entirely inside the ear canal. Starkey’s Genesis AI CIC model is unique for its small size and built-in Bluetooth functionality, allowing wireless streaming without compromising discretion. However, because of their compact size, CIC models are typically less powerful and are better suited for people with mild to moderate hearing loss.

Invisible-in-canal (IIC)

IIC hearing aids are the smallest and most discreet option, sitting completely inside the ear canal and remaining nearly undetectable. Starkey’s Signature Series IIC models are a great choice for users who prioritize invisibility over features like Bluetooth streaming and app connectivity. These hearing aids are ideal for people with mild to moderate hearing loss who want a barely-there hearing solution and don’t mind compromising on battery life and advanced functions.

Does Starkey offer a free hearing test online?

Yes, Starkey offers a free hearing test online, which provides a convenient first step if you suspect you may have hearing loss. While it’s not a replacement for a full hearing exam from a hearing care professional, it can help determine if you need further evaluation. The test assesses how well you hear different sounds and frequencies, giving you a basic understanding of your current hearing ability.

To access the hearing test, visit Starkey’s website, where you can take the test from the comfort of your home. The process is simple: You’ll be prompted to answer a few questions about your hearing experiences and then listen to a series of tones and speech sounds through your device’s speakers or headphones. After the test, Starkey will provide you with immediate results, indicating whether you have normal hearing or signs of hearing loss.

Keep in mind that the online test is not a comprehensive evaluation. If the results suggest potential hearing issues, it’s a good idea to schedule an appointment with a hearing care professional for a thorough in-person assessment.

Starkey tinnitus technology

What is tinnitus?

Tinnitus is when a person experiences ringing, buzzing, hissing, or other sounds in one or both ears that no one else can hear. These sounds can vary in pitch and intensity and may be constant or intermittent. 

Causes and symptoms of tinnitus

Tinnitus has a range of causes, most commonly related to exposure to loud noises, age-related hearing loss, or ear damage. It can also be linked to medical conditions like high blood pressure, ear infections, or even medications. In some cases, tinnitus is a side effect of prolonged exposure to loud environments, like concerts or industrial settings. Common symptoms include persistent ringing, buzzing, or clicking sounds that are most noticeable when it’s quiet or when trying to sleep.

“In quiet environments, our brain is trained to listen to sound 24/7 and identify what types of sounds are safe and what could potentially pose a threat to our safety. When you start developing hearing loss your brain is not receiving sounds from certain pitches or certain areas or in the quantity that it’s expecting. So it goes searching for these sounds and basically starts to make them up,” says Rachel Cook, an audiologist at HearingUp. 

Tinnitus can take a strong emotional toll and cause a lot of anxiety and stress. “It can easily turn into a vicious cycle where it becomes the only thing you notice anymore,” Cook adds.

How Starkey tinnitus technology provides relief

Starkey hearing aids use Multiflex Tinnitus Technology, designed specifically to help manage and reduce the effects of tinnitus. This feature works by providing sound therapy directly through the hearing aids, masking the internal sounds caused by tinnitus. Starkey’s tinnitus relief technology plays soothing tones and sounds that can distract the brain from ringing or buzzing.

Users can personalize the sound therapy through the My Starkey or Thrive apps, allowing them to adjust volume and pitch to find the most comfortable settings. Starkey’s hearing aids are also compatible with the Relax app, which offers more tools for managing tinnitus, such as guided relaxation exercises.

Our testing experience

With FDA approval, the OTC hearing aid market experienced rapid growth with an influx of new companies. While this improves accessibility and helps drive down prices, it also muddies the waters. How do you know which products are trustworthy? 

When choosing hearing aids to test, we survey the market, interview hearing health experts, and speak to real hearing aid users. To date, we’ve curated a list of 21 OTC models to test from nine brands: Audien, Audicus, Eargo, Go Hearing, Jabra Enhance, Lexie, Lucid, MDHearing, and Sony. We chose these brands because they have positive reputations and represent a range of prices, styles, and features. 

We also tested prescription models from Oticon, Phonak, and Starkey to experience the difference between OTC and Rx (prescription) hearing aids firsthand. 

The process looked like this:

Our testers try multiple devices and answer 25 questions about each. We use these answers to look for outstanding performers. For example, the clarity of the Jabra Enhance Select 200 immediately catches our testers’ attention like no other OTC hearing aid.

From our expert

“Jabra Enhance Select 200 has great sound quality for different environments. I can really tell the difference between the listening programs.”

We also look for hearing aids that demonstrate consistent quality in fundamental features, like sound clarity, setup, comfort, and ease of use. Brands that don’t meet those standards didn’t make it onto our best-of list. 

No brand’s hearing aids perform flawlessly. For example, one of our testers runs into trouble right away with the MDHearing Volt: the Quick Start Guide doesn’t explain how to turn it on.

We also complete onboarding calls with brand audiologists and talk with customer service representatives over the phone and through chat modules to accurately replicate the buying process and evaluate post-purchase support options.

Finally, we continue our testing by interviewing independent audiologists, hearing instrument specialists, mental health experts, and hearing aid users to get additional perspectives on OTC hearing aids.

 The case for OTC hearing aids is particularly compelling. Being able to reach a wider population by increasing accessibility, simplifying the ease of fitting, and reducing the cost barriers … opens the gateway to an array of possibilities [previously inaccessible] due to exorbitant costs and lack of insurance coverage.

Frequently asked questions

Starkey hearing aids may be worth the price for those seeking advanced features like AI-driven sound adjustments, health monitoring, and top-notch sound quality. While they come with a premium cost, they offer technology and customization options like wellness tracking that may help people hear better and monitor their health.

On average, Starkey hearing aids last three to five years, depending on care and usage. With proper maintenance, they can last longer, but regular upgrades may be needed to keep up with evolving technology and to maintain optimal performance.

Most Starkey hearing aids are highly water-resistant but not fully waterproof. Most models are rated IP68, meaning they can handle sweat, moisture, and dust, but they should not be submerged in water. The rechargeable Signature Series model is the one exception and is fully waterproof up to one meter.

Yes, you can answer the phone with a Starkey hearing aid. Most iPhone users can use hands-free calling with Starkey hearing aids via Bluetooth. For Android users, hands-free calling is more limited, and you may need to speak directly into the phone’s microphone while hearing the call through your hearing aids.
