The $4,000 hearing aids get the attention. The $8 wax guard pack that keeps them working — not so much. But the accessories category is real money over time, and most buyers don’t factor it in when they’re sitting in the audiologist’s office. According to the NIDCD, roughly 37.5 million American adults report some degree of hearing trouble. Most of the ones who wear hearing aids will spend $100–$500 per year on the supplies and add-ons that keep those devices performing at their best.
Here’s the complete picture.

Batteries: Disposable vs. Rechargeable
If you wear traditional hearing aids with a battery door, you’re going through disposable zinc-air batteries on a regular schedule. Size 312 batteries — the most common for receiver-in-canal (RIC) aids — run $3–$8 for a pack of eight and last three to seven days per pair, depending on streaming use. Size 13 and 675 batteries, used in larger aids and cochlear implant processors, last longer and cost similar per-pack.
Monthly battery cost for most users: $5–$15 with moderate streaming, up to $20–$25 with heavy Bluetooth use (streaming drains batteries faster).
Rechargeable hearing aids have changed the math for many users. No disposable cells to buy — but the lithium-ion battery cells inside the aids eventually degrade and need professional replacement. That service typically runs $50–$150 per pair at an audiology clinic and is needed every one to two years. Still cheaper than years of disposables, but it’s not zero cost.
Buying batteries in bulk from online retailers (Amazon, Costco, Harris Communications) typically costs 40–60% less per battery than purchasing them at an audiology office. A 60-pack of size 312 batteries runs $10–$18 online versus $2–$3 per 4-pack at a clinic. If you use disposable batteries, buying online saves $30–$80 per year without any compromise in quality.
Domes and Ear Tips
Most receiver-in-canal and open-fit hearing aids use soft silicone domes that sit in the ear canal. These get waxy, compressed, and less effective over time. Replacing them every two to three months keeps the fit comfortable and the sound quality consistent.
A pack of ten domes runs $10–$30, depending on brand and size (open, closed, or power dome styles). Your audiologist can give you the correct size — getting this wrong affects both comfort and acoustic performance. You’ll go through four to six packs per year, so budget $40–$120 annually.
Wax Guards and Filters
The receiver — the tiny speaker that sits in your ear canal — is the component most commonly damaged by earwax. Wax guards are small mesh filters that block wax from getting into the receiver. They need to be replaced about once a month, or immediately if sound gets muffled or blocked.
A pack of eight wax guards runs $8–$20, depending on brand (Phonak, Oticon, ReSound, Starkey all use different systems). Annual cost: $96–$240. It’s the most tedious part of hearing aid maintenance, but skipping it leads to expensive receiver replacements ($75–$200 per ear).
Cleaning Kits and Dehumidifiers
A basic cleaning kit — a brush, wax loop, and vent cleaner — costs $15–$40 and should be replaced or replenished annually. You’d use it daily to brush the microphone ports and vent openings.
Dehumidification is worth taking seriously. Moisture is the leading cause of hearing aid failure, and it accumulates from daily ear canal humidity and perspiration — not just rain or sweat. Overnight in a drying unit consistently extends device lifespan.
- Desiccant jar (Dry-Aid, hearing aid dehumidifier capsule): $15–$35; replace the desiccant capsule every two to four weeks
- Electronic drying unit (Phonak DryBox, Zephyr DryCaddy): $50–$150; heated and UV drying; more effective, especially in humid climates or for active users
If you’re spending $3,000–$6,000 on hearing aids, a $75 electronic dryer that extends their life by a year or two is a straightforward investment.
TV Streamers and Bluetooth Accessories
TV is one of the most common frustration points for hearing aid users — even well-programmed aids struggle when dialogue, music, and background noise compete. A TV streamer plugs into your TV’s audio output and transmits audio directly to your aids, delivering a clean close-range signal regardless of room acoustics.
TV streamers cost $150–$300 and are brand-specific: a Phonak TV Connector won’t work with Oticon aids. If you’re buying, verify compatibility with your specific model. Many newer hearing aids with direct Bluetooth can stream from a smart TV’s Bluetooth output directly — ask your audiologist whether your aids support this before buying a dongle.
Remote microphones (also called partner mics or remote mics) clip to a speaker’s lapel and transmit their voice directly to your aids. They’re most useful in noisy restaurants, meetings, and lecture settings — situations where the 18-inch distance between your hearing aid microphone and the person speaking creates a processing challenge. These run $200–$400 at the entry level.
Accessories are brand-locked to your hearing aid manufacturer. Before purchasing any TV streamer, remote mic, or Bluetooth accessory, confirm it’s compatible with your specific hearing aid model and generation. Manufacturers sometimes break compatibility between product generations — a streamer purchased for one model may not work with a newer model from the same brand. Always verify on the manufacturer’s website or ask your audiologist before buying.
Annual Accessory Budget: What to Expect
If you’re wearing traditional disposable-battery aids and doing your maintenance properly:
- Batteries: $60–$180
- Domes: $40–$120
- Wax guards: $96–$240
- Cleaning kit and dehumidifier supplies: $30–$60
- Maintenance subtotal: $226–$600 per year
If you own rechargeable aids and a TV streamer (already purchased), ongoing costs drop to roughly $100–$250 per year for domes, wax guards, and cleaning supplies.
The first year often runs higher because you’re buying the dehumidifier unit, cleaning kit, and possibly a TV streamer or remote mic. After that, it settles into predictable consumable costs. Building this into your budget from day one — rather than being surprised by it — makes managing the total cost of hearing aid ownership a lot more straightforward.
Frequently Asked Questions
Hearing aid batteries typically cost $150–$250 annually, depending on battery type and usage patterns. Most users need 4–8 batteries per month at $1.50–$3 per battery, with rechargeable hearing aids eliminating this recurring expense entirely.
Most traditional health insurance plans and Medicare do not cover hearing aid accessories, leaving users to pay out-of-pocket for batteries, domes, wax guards, and cleaners. Some supplemental insurance or employer-sponsored plans may offer limited coverage, so check your specific policy details with your provider.
Domes typically need replacement every 3–6 months and cost $15–$40 per pack, while wax guards should be replaced monthly at $4–$8 per pack. Regular replacement prevents sound quality issues and extends the lifespan of your hearing aids.
