How are hearing aids, amplifiers, and volume booster apps classified?
Before comparing products, you need to understand what the FDA actually considers each one to be. Getting this wrong can mean spending money on the wrong solution, or worse, delaying necessary medical treatment.
Prescription Hearing Aids = FDA Class I/II Medical Devices
Traditional hearing aids are FDA-regulated medical devices. A hearing-care professional can evaluate your hearing and adjust a device for you. Regulatory requirements and premarket pathways vary by device; see the FDA's guide to getting hearing aids and its consumer information for current details.
OTC Hearing Aids = New FDA Category (Since 2022)
In August 2022, the FDA finalized a rule creating a new over-the-counter hearing aid category for adults with perceived mild to moderate hearing loss. These can be purchased without a prescription or audiologist visit. They still must meet FDA safety and labeling requirements, but they lack the personalized professional fitting of prescription devices. OTC devices typically cost far less than prescription hearing aids.
PSAPs = Not Hearing Aids
Personal Sound Amplification Products (PSAPs) are not FDA-regulated as medical devices. They amplify all sounds uniformly and are not intended for people with hearing loss. The FDA has explicitly stated that PSAPs are not a substitute for hearing aids. Some inexpensive devices marketed online blur this distinction, which can mislead consumers.
VoicyCare = A Music Player App
VoicyCare is none of the above. It is a music player app that plays audio files stored on your iPhone with volume boost (up to 500%, or 5x, with earphones or headphones connected; up to 100% on the built-in speaker) and a 5-band equalizer. It does not use the microphone to capture environmental sound. It does not amplify conversations. It is not intended to treat hearing loss.
The developer does not consider this app a substitute for hearing aids. The use cases are entirely different.
What is a hearing aid, and what are its trade-offs?
How They Work
The core components are a microphone, a digital signal processor, and a speaker. Modern digital hearing aids use your audiogram to apply frequency-specific amplification: boosting the ranges where your hearing has declined while leaving audible frequencies mostly alone. They also include noise reduction, feedback cancellation, and directional microphones that prioritize the speaker in front of you.
This is technology specifically engineered for speech intelligibility in real-world environments.
What They Cost
Prescription hearing aids are a significant expense, often thousands of dollars per ear, and a pair costs more. OTC hearing aids are generally much cheaper but offer less customization. Most US health insurance provides limited hearing aid coverage, though this is slowly changing.
Strengths
- Real-time amplification of all environmental sounds: conversations, TV, phone calls, doorbells
- Professionally fitted to your specific audiogram with dozens of processing channels
- FDA-regulated for safety and efficacy
- Designed for all-day comfort
Limitations
- Expensive. Even OTC models are a significant purchase
- Prescription devices require audiologist visits for fitting and follow-up
- Ongoing maintenance: batteries/charging, earwax cleaning, moisture management
- On some models or speech-focused programs, music dynamics or tone can sound different. Ask the provider whether a music program or streaming option is available. For details, see why music can sound different with hearing aids
How well do the AirPods Pro 2 hearing features work?
In September 2024, Apple received FDA authorization for AirPods Pro 2 to function as an OTC hearing aid software device, the first of its kind. With iOS 18.1 and later, AirPods Pro 2 can perform a pure-tone hearing test and apply personalized amplification for mild to moderate hearing loss.
What It Can Do
- Hearing test: A ~5-minute pure-tone audiometry test conducted with AirPods Pro 2 and your iPhone
- Hearing aid mode: Personalized amplification based on test results, targeting mild to moderate loss
This costs much less than traditional hearing aids.
What It Cannot Do
- Does not address severe hearing loss
- Self-administered test, not professional audiological evaluation
- Battery life is standard AirPods duration, not designed for all-day wear the way hearing aids are
- Still earbuds, not a dedicated hearing device
For someone hesitant about visiting an audiologist, AirPods Pro 2 can serve as a useful first step; the hearing test alone gives you data. But for confirmed hearing loss, professional evaluation remains important.
What does VoicyCare actually do?
To repeat: VoicyCare is not a hearing aid alternative.
VoicyCare plays music files (MP3, WAV, M4A, FLAC, AAC, and OGG (Opus)) stored on your iPhone. During playback, it can amplify volume up to 500% (5x) with earphones or headphones connected (up to 100% on the built-in speaker) and adjust frequency balance across five EQ bands.
The iPhone's built-in Music app has no meaningful volume boost or granular EQ control; VoicyCare fills that gap. The app's purpose is narrow: make music sound better for people who need a bit more volume or a different frequency balance. That is all. For a comparison with other options on the market, see the 5 ways to boost iPhone volume guide.

When should you see an audiologist?
If any of the following apply to you, the right first step is a professional hearing evaluation, not an app or consumer device.
- You frequently ask people to repeat themselves
- Others tell you the TV is too loud
- Phone conversations are hard to follow
- You have sudden hearing loss in one ear (see an ENT promptly; early treatment matters)
- You have persistent tinnitus
The cause and appropriate response to hearing difficulty cannot be determined by age alone. Seek an evaluation when it affects daily life.
Where does VoicyCare fit in?
VoicyCare is useful in specific situations:
- Music volume is the only issue: Daily conversations are fine, but music on your iPhone sounds too quiet. The volume boost (up to 500% (5x) with earphones or headphones) addresses this
- You want to adjust music tone: The 5-band EQ changes the balance of bass, midrange, and treble according to listening preference
- You use hearing aids and want to improve music playback: Ask your audiologist about music programs, fitting, and supported streaming. An app is not a substitute for those adjustments
- You need a large-text interface: VoicyCare displays song titles, artist names, and controls in large, readable text. The music apps for seniors guide compares app options by text size, ease of use, and accessibility features
What are the risks of turning up the volume?
Any volume amplification tool carries risk. WHO guidance gives 80 dB for 40 hours a week as a listening-duration guideline; sustained exposure beyond that can cause permanent hearing damage. Cranking VoicyCare to 500% (5x) and listening for hours is not what I recommend.
The equalizer changes music tone. It is not a substitute for hearing-based amplification or professional assessment.

What's the difference between hearing aids and volume booster apps?
Hearing aids are regulated medical devices that amplify per-frequency based on a hearing test, providing personalized correction. Volume booster apps (like VoicyCare) are not medical devices and simply increase the playback volume of audio files digitally. They serve different purposes: VoicyCare adjusts volume and sound for music, and can support music listening for hearing aid users. If you have difficulty hearing conversations, see an ENT doctor rather than relying on an app.
What is the AirPods Pro 2 hearing aid feature?
Starting with iOS 18.1, AirPods Pro 2 function as an FDA-authorized OTC (over-the-counter) hearing aid in the U.S. Users can take a hearing check and the device applies a frequency-specific amplification profile based on the result. Availability and regulatory classification varies by country.
Is VoicyCare a medical device?
No. VoicyCare is a general consumer audio playback app, not a medical device. It is not intended to diagnose, prescribe, or treat hearing loss. If hearing difficulty is affecting your daily life, please get a hearing test from an ENT specialist first.
When should I see an ENT (ear, nose, throat) doctor?
Sudden hearing loss (possible sudden sensorineural hearing loss / SSNHL) / accompanying tinnitus or aural fullness / others tell you that you mishear conversations / hearing loss in only one ear — see an ENT promptly. SSNHL outcomes depend on how soon treatment begins.
What are the risks of constantly raising the volume?
WHO materials include 80 dB for 40 hours per week in weekly-exposure guidance. NIOSH's 15 minutes per day at 100 dB is an occupational-exposure reference, not a guaranteed safe duration for personal music listening. VoicyCare can use up to 500% (5x) playback gain with earphones or headphones connected (up to 100% on the built-in speaker), but actual output varies with the source and connected device. Use lower volume and breaks where possible.
What's the takeaway?
- Hearing aids are FDA-regulated medical devices. If hearing loss affects daily life, including moderate to severe loss, consult a hearing-care professional about suitable devices and fitting
- OTC hearing aids (available since 2022) are intended for adults with perceived mild to moderate hearing loss and can be purchased without a prescription. Professional advice and fitting support may still be useful
- AirPods Pro 2 received FDA OTC hearing aid authorization in 2024. Useful for mild to moderate loss, with a built-in hearing test. Not a substitute for professional evaluation
- VoicyCare is a music player app. Not a hearing aid. Not a medical device. It adjusts volume and EQ when playing music files. Free
- If daily conversations are difficult, see an audiologist. That is the priority, not an app
Use the right tool for the right job. Hearing aids for hearing loss. VoicyCare for music. They solve different problems, and trying to substitute one for the other will not work.
