Recognizing hearing change

Signs your family notices first

People with gradual hearing loss often don't notice it themselves. Common early signals: asking people to repeat themselves, turning the TV up, missing parts of phone calls, withdrawing from group conversations, and mishearing in restaurants. If two of these are familiar, it's worth a hearing screen.

When to see an audiologist (not OTC)

Sudden hearing loss, one-sided loss, pain, drainage, ringing that won't stop (tinnitus), dizziness, or hearing loss after a head injury are all reasons to skip OTC products and see a clinician. OTC hearing aids are FDA-regulated only for perceived mild-to-moderate loss in adults 18+.

How a hearing test actually works

An audiologist plays tones at different pitches and volumes and maps the softest sound you can hear at each — producing an audiogram. Self-administered in-app tests follow the same logic but with less precision than a sound booth.

Before you buy online

Checklist

Trial period & return policy

Most reputable OTC sellers offer at least a 45-day risk-free trial. Read the return rules carefully — some require the original packaging or charge a restocking fee.

Checklist

Warranty length

Look for at least a 1-year warranty on the device itself, separate from the trial window. Premium products often offer 2-year coverage.

Checklist

Support channels

Phone support during U.S. business hours and access to a hearing professional (even by video) are useful, especially for first-time users.

Checklist

App requirements

If the device requires a smartphone for setup, confirm whether it works with both iOS and Android, and what the experience is like without the app for daily use.

Checklist

Battery vs rechargeable

Rechargeable models are easier for many seniors. Confirm typical battery life per charge and how the charging case behaves when traveling.

Checklist

Fit & comfort

Multiple dome or tip sizes usually ship in the box. Plan to try a few during the first week — the right fit is the single biggest predictor of daily wear.
