Quick Answer: A complete hearing aid accessory kit covers five bases: power (rechargeable charger or zinc-air batteries), protection from moisture (a dryer — roughly 80% of hearing aid repairs are moisture-related, per industry drying-product makers PerfectDry and Dry & Store), cleaning (a brush-and-pick kit plus correctly sized domes and wax guards), loss prevention (a retention clip), and storage (a hard-shell travel case). Below is a quick pick for each category, with a link to our full in-depth guide if you want the complete breakdown before buying.
Most first-time buyers budget for the hearing aid itself and stop there — then discover a few weeks in that the device alone doesn’t cover power, cleaning, or protection. None of these are optional add-ons a manufacturer invented to upsell you; each solves a specific, common failure mode. This guide is the fast version: one solid pick per category, so you can stock a complete kit in a single order instead of researching each piece separately.
Hearing aid accessories by the numbers
- ~80% of hearing aid repairs are moisture-related, according to figures cited across the hearing-care industry by drying-product makers like PerfectDry and Dry & Store — the single biggest argument for a nightly dryer routine.
- ~$2,300 is the average cost to replace a single hearing aid, with a pair commonly running $2,000–$4,000, per cost reporting cited by Amplifon Hearing Health Care — the number that makes a $10–$25 clip or case cheap insurance by comparison.

1. Batteries or a charger — power comes first
If your hearing aid takes disposable zinc-air cells, keep a running supply on hand rather than waiting until you’re down to one. If it’s rechargeable, the manufacturer’s own charging dock is almost always the right buy — third-party chargers risk a poor contact fit.
Rayovac Advanced Zinc-Air Hearing Aid Batteries
- Standard zinc-air cells reach full rated voltage after the tab-pull activation window, so pull tabs a few minutes before you need them rather than the moment you insert the aid.
- No carry-on restriction when traveling — pack a spare card in any bag.
Once you know your size, Amazon Prime’s free 30-day trial gets a fresh batch to your door in two days instead of scrambling to a pharmacy mid-week — worth it if you’ve ever been caught with a dead battery and no backup.

2. A dryer — the accessory that prevents the most failures
Dry & Store Zephyr
- Pulls sweat and ambient humidity out of the device overnight, addressing the failure cause behind roughly 80% of repairs.
- A five-minute cycle fits into a normal bedtime routine without adding real friction.
See our best hearing aid dryer guide for desiccant-only options if you want something cheaper and travel-friendly instead of an electric unit.
3. A cleaning kit and correctly sized domes/wax guards
A brush-and-pick cleaning tool clears earwax and debris from the microphone and receiver ports daily, while domes and wax guards need to match your exact model and size — check your device’s manual or app before ordering, since these aren’t universal across brands.
Hearing Aid Cleaning Kit
- Clearing debris daily prevents the muffled-sound complaints that often get mistaken for worsening hearing loss.
- Pair with a sized wax-guard multipack matched to your specific model.

4. A retention clip and a travel case — loss and impact protection
Ear Gear Original Retention Clip
- A cheap safeguard against a roughly $2,300-per-device replacement cost if an aid slips off during activity.
- Pair with a hard-shell case like CASEMATIX for the suitcase itself — a clip protects against loss while worn, a case protects against being crushed in storage.
See the full rundown in our best hearing aid clip and best hearing aid travel case guides, plus hearing aid warranty coverage for what happens if a loss does slip through.
Building your kit in one order
- Confirm your exact model and size first — domes, wax guards, and chargers are brand- and often model-specific, so check your app or manual before ordering anything but batteries, a dryer, a case, or a clip.
- Start with power and moisture protection. These two categories prevent the most day-to-day problems and downtime.
- Add cleaning and loss-prevention gear next. A brush-and-pick kit and a retention clip round out daily-use protection.
- Buy a travel case last, once you know what else needs to fit inside it alongside the aids.
The bottom line
A complete hearing aid accessory kit doesn’t need to be complicated: batteries or a charger for power, a dryer for the moisture damage that causes most repairs, a cleaning kit plus correctly sized domes and wax guards for upkeep, a retention clip to prevent an expensive loss, and a travel case for storage.
