Hearing Aid Accessories: Which Add-Ons Are Worth Asking About?

People discover hearing aid accessories after the first purchase, when the TV streamer is not in the box, the wax filters run out, or the clinic mentions a remote control as an optional extra. The confusion is predictable: some accessories are bundled, some are sold separately, and compatibility is a minefield of brand ecosystems and model-year changes. This guide explains what each accessory category does, which are worth asking about, and the questions to ask before you pay for add-ons.

What counts as a hearing aid accessory? The direct answer

What are hearing aid accessories? Accessories are the tools, consumables, and optional add-ons that support daily hearing aid use. The most common categories are TV streamers and remote controls, smartphone apps, chargers and charging cases, drying kits and dehumidifiers, consumable wax filters and domes, retention clips and sport locks, and carrying cases and travel kits. Some are included in the initial purchase, some are sold separately, and some are available only through the manufacturer or clinic.

Accessories fall into three buckets:

• Bundled essentials: Chargers (for rechargeable models), initial wax filters and domes, cleaning tools, and user guides. These usually come with the hearing aids at purchase.
• Optional convenience add-ons: TV streamers, remote controls, drying kits, extra charging cases, and travel cases. These improve specific use cases but are not required for basic operation.
• Consumables and replacements: Spare wax filters, domes, thin tubes, and batteries (for disposable-battery models). These wear out and must be reordered. For zinc-air disposable battery guidance, see our hearing aid batteries guide.

TV streamers and remote controls

TV streamers send TV audio wirelessly into your hearing aids, bypassing room acoustics and background noise. You plug the streamer into the TV's audio output (optical, AUX, or HDMI ARC), and it transmits to your hearing aids. You hear the TV at your preferred volume, and others in the room hear the TV speakers at their preferred volume.

How TV streamers work

• Proprietary wireless protocols: Most TV streamers from hearing aid manufacturers (such as Phonak TV Connector, Oticon TV Adapter, ReSound TV Streamer+, Signia StreamLine TV, and Starkey TV Streamer) use a brand-specific wireless protocol. The streamer only works with that brand's hearing aids, and often only with specific models released in a certain year or later.
• Bluetooth Classic streamers: Some older hearing aids use Bluetooth Classic for TV streaming. These streamers pair like a Bluetooth speaker and may have slightly higher latency (audio delay) than proprietary protocols.
• Auracast transmitters: Hearing aids with Auracast support can connect to Auracast-enabled TV transmitters without brand-locked pairing. Auracast is newer, and adoption is growing as of 2026. For details on Auracast broadcast audio, see our Bluetooth and Auracast guide.

Remote controls

Remote controls are small handheld devices that adjust hearing aid volume, switch programs, and mute microphones without using your phone. They are most useful for users who do not carry a smartphone, who have difficulty with touchscreen apps, or who want tactile buttons instead of tapping a screen. Most manufacturers offer a remote as an optional accessory. Prices vary by brand and model, so ask your clinic or check the manufacturer.

Smartphone apps have largely replaced remote controls for most users because the app is free, always with you, and offers more control options. For more on apps, see the next section.

Smartphone apps

Hearing aid apps from major manufacturers are free downloads that pair with your hearing aids via Bluetooth. The app becomes a remote control, sound adjustment tool, and sometimes a remote fitting assistant.

What apps typically do

• Volume and program control: Adjust overall volume, change listening programs (such as restaurant, music, outdoor), and balance left and right ears.
• Treble and bass adjustment: Some apps let you customize frequency response in real time, though the range of adjustment depends on the model and technology tier.
• Streaming controls: When streaming phone calls, music, or media, the app shows battery level, connection status, and sometimes audio source selection.
• Find my hearing aid: Most apps can ping your hearing aids or show their last known location on a map if you misplace them.
• Tinnitus masking (if supported): Hearing aids with tinnitus features often control the masking sound (white noise, ocean waves, etc.) through the app. For more on tinnitus features, see our hearing aids for tinnitus guide.
• Remote fitting and adjustments: Some manufacturers and clinics offer remote fine-tuning sessions where your audiologist adjusts settings through the app while you are at home. This feature depends on the model and the clinic's service offerings.

App compatibility

Apps are brand-specific. Phonak hearing aids use the myPhonak app, Oticon uses Oticon Companion, ReSound uses ReSound Smart 3D, Signia uses the Signia app, Starkey uses Thrive, and Widex uses the Widex app. You cannot use the Phonak app with Oticon hearing aids.

Platform support depends on the hearing aid's Bluetooth protocol. Hearing aids with Made for iPhone (MFi) or Bluetooth LE Audio work with iOS. Hearing aids with Android Streaming for Hearing Aids (ASHA) or LE Audio work with Android. Most current models support both platforms. For a detailed explanation of Bluetooth protocols, see our Bluetooth and Auracast guide.

Chargers and charging cases

Rechargeable hearing aids come with a charging case. The case is usually included in the purchase price, but some manufacturers offer multiple charger options, and upgrades or replacements cost extra.

Types of chargers

• Standard desktop chargers: A small dock or case that plugs into a wall outlet. You place the hearing aids in the charger at night, and they charge in 3 to 4 hours. Most provide a full charge (16 to 24 hours of use).
• Portable charging cases: These include a built-in battery, so you can charge your hearing aids without a wall outlet. They work like a power bank for your hearing aids and are useful for travel, camping, or areas without reliable electricity. A portable charger typically holds enough power for 2 to 4 full charges before the case itself needs recharging.
• Premium or UV-sterilizing chargers: Some manufacturers offer chargers with UV-C light sterilization or desiccant drying compartments. These cost more than standard chargers but combine charging with cleaning and drying. Whether the premium is worth it depends on your care routine and whether you already use a separate dryer.

Charger compatibility

Chargers are brand-specific and often model-specific. A Phonak Audéo charger will not charge Oticon Real hearing aids. Even within one brand, newer models may use a different charger than older models. If you lose or damage your charger, you must replace it with the exact model designed for your hearing aids. Replacement charger prices vary by brand and model, so ask your clinic or check the manufacturer.

For the trade-offs between rechargeable and disposable-battery hearing aids, including what happens when the lithium-ion battery wears out, see our rechargeable vs. battery guide.

Dryers and dehumidifiers

Moisture is one of the leading causes of hearing aid failure. A nightly drying routine removes sweat, humidity, and condensation that accumulate during daily wear. Purpose-built hearing aid dryers are inexpensive accessories that can prevent expensive repairs.

Types of dryers

• Desiccant dehumidifiers: A small jar or case with desiccant beads (silica gel or similar). You place the hearing aids inside overnight, and the beads absorb moisture. The beads eventually saturate and must be replaced or regenerated. Prices vary by brand and model, so ask your clinic or check the manufacturer.
• Electric dryers: A small device that uses gentle heat (below damaging temperatures) and sometimes a fan to evaporate moisture. You place the hearing aids inside, turn it on, and let it run for a few hours or overnight. Electric dryers do not require consumable beads. Prices vary by brand and model, so ask your clinic or check the manufacturer.
• UV-C dryers: These combine drying with ultraviolet light to sterilize the hearing aids. UV-C light kills bacteria and mold that can grow in moist earpieces. UV dryer prices vary by brand and model, so ask your clinic or check the manufacturer. Whether the UV feature is necessary depends on how prone you are to ear infections and how thoroughly you clean your hearing aids. For cleaning routines, see our cleaning hearing aids guide.

What not to use as a dryer

The U.S. Food and Drug Administration (FDA) care guidance for hearing aids warns users to avoid heat sources such as hair dryers, ovens, microwaves, and car dashboards, because heat can damage internal electronics (FDA: How to Get Hearing Aids, content current as of November 18, 2022). Do not use a hair dryer, rice bag, or other household heat source as a drying substitute. Purpose-built dryers are designed to stay within safe temperature limits.

Wax filters, domes, and tubes (consumables you will reorder)

Wax filters, domes, and thin tubes are consumable parts that wear out and must be replaced regularly. They are not optional accessories; they are part of ongoing hearing aid maintenance.

Wax filters

Wax filters (also called cerumen guards or wax guards) sit in the receiver or sound outlet to block earwax from entering the electronics. Wax clogs filters over time, reducing sound quality and volume. Most manufacturers recommend replacing wax filters about once a month, or sooner if sound drops or the filter looks clogged.

Wax filters are matched to the receiver or earpiece design. The part number and tool matter: Phonak CeruShield, Oticon ProWax, ReSound WaxStop, Signia Click Sleeves, and Starkey Livio filters are not interchangeable. Always order the exact filter type your clinician specifies.

For detailed wax filter replacement cadences by manufacturer and model, see our cleaning hearing aids guide.

Domes

Domes are the soft silicone or rubber tips that sit in your ear canal on RIC (receiver-in-canal) and some BTE (behind-the-ear) hearing aids. Domes come in different sizes (small, medium, large) and vent styles (open, closed, power). They wear out, harden, or tear over time and should be replaced monthly or as your clinician advises.

Like wax filters, domes are model-specific. The receiver diameter and attachment design vary by brand and model year. For a complete guide to dome styles, sizes, and replacement schedules, see our hearing aid domes guide.

Thin tubes and earmolds

BTE hearing aids with thin tubes or custom earmolds require periodic tube replacement. Thin tubes yellow, stiffen, or crack after months of use and should be replaced by your hearing care provider when they degrade. Custom earmolds last longer but may need refitting if your ear shape changes or if the mold becomes stiff or cracked.

Retention clips and sport locks

Retention accessories keep hearing aids secure during physical activity, sports, or for users with small or uniquely shaped ears.

• Retention clips: Small wire or cord clips that attach to the hearing aid and hook over the ear or clip to clothing. They prevent the hearing aid from falling if it comes loose. Some manufacturers include retention clips in the box; others sell them separately.
• Sport locks or retention sleeves: Silicone sleeves that fit over BTE or RIC hearing aids and wrap around the ear for a more secure fit. These are useful for running, cycling, or activities where sweat and movement can dislodge hearing aids.
• Headbands or hats with built-in retention: Some third-party accessory makers sell headbands or hats designed to hold hearing aids in place during sports. These are niche products and are not universally compatible.

Generic retention clips and cords work with most hearing aid styles. Sport locks are often brand-specific because they must fit the exact shell shape.

Carrying cases and travel kits

Hearing aids are expensive and fragile. A protective case is useful for travel, storage, and protecting devices when not in use.

• Hard-shell cases: Rigid cases with foam inserts to hold hearing aids, spare domes or filters, cleaning tools, and a charging cable. These protect against drops and crushing in luggage. Prices vary by brand and model, so ask your clinic or check the manufacturer.
• Soft pouches: Fabric or neoprene pouches that protect against scratches but not hard impacts. These are lighter and more compact than hard cases. Prices vary by brand and model, so ask your clinic or check the manufacturer.
• All-in-one travel kits: Some manufacturers or third-party sellers offer kits that include a case, spare wax filters and domes, a cleaning brush, and a portable charger or battery caddy. These are convenient for travel but cost more than buying components separately.

Most hearing aids come with a basic case at purchase. Upgrade cases are optional.

Questions to ask before you buy accessories

Before you purchase hearing aid accessories, ask these compatibility and bundling questions:

1. What accessories are included in the purchase price?

Bundled packages vary widely by clinic and manufacturer. Some providers include a TV streamer, drying kit, extra wax filters and domes, and a premium charging case in the initial quote. Others charge separately for every accessory beyond the charger and basic supplies. Ask for an itemized list of what comes with the hearing aids and what costs extra.

2. Is this accessory compatible with my specific model?

Chargers, TV streamers, remote controls, and wax filters are often model-specific, not just brand-specific. A Phonak TV Connector may work with Phonak Audéo Lumity but not with older Phonak Audéo Paradise or Audéo Marvel models. Before you buy an accessory online or from a third party, confirm the exact model compatibility. The product listing should name compatible hearing aid models by year and product line.

3. Can I use accessories from my previous hearing aids?

Usually no. Even if your new hearing aids are from the same manufacturer, accessories are often not backward-compatible across model generations. The exception is generic accessories such as drying kits, storage cases, and cleaning brushes, which work with any hearing aid.

4. Where do I reorder wax filters, domes, and other consumables?

Some clinics include consumable supplies in follow-up visit packages or sell them at cost. Others expect you to order directly from the manufacturer or from online retailers. Ask where to reorder, because replacement filter and dome kits vary widely in price depending on brand and quantity.

5. Does the TV streamer require a specific hearing aid feature or technology tier?

Some TV streamers and remote controls only work with mid-tier or premium hearing aid models because they require certain Bluetooth or wireless radio hardware. Confirm that your specific model supports the accessory before you buy it. For Bluetooth and Auracast compatibility, see our Bluetooth and Auracast guide.

6. If I need a replacement charger, how much does it cost and how quickly can I get it?

Losing or damaging your charger renders rechargeable hearing aids unusable once the current charge depletes. Ask the clinic or manufacturer what the replacement cost is and whether they stock spares or if you must wait for shipping. Some users keep a backup charger for this reason. Replacement prices vary by brand and model, so ask your clinic or check the manufacturer.

7. Are there third-party or generic alternatives?

For consumables such as drying kits, storage cases, and cleaning brushes, generic third-party options are usually fine and often cheaper than brand-name equivalents. For electrical accessories such as chargers and streamers, stick with manufacturer-approved products to avoid compatibility and safety issues.

Where this fits in a purchase (soft product context)

Accessories are part of the total cost of ownership but not a separate product category you shop for on their own. When you browse the hearing aid catalog, ask each clinic which accessories are bundled in the quoted price and which cost extra. The decision order remains audiogram, loss pattern, style, features, and technology tier (see how to choose hearing aids). Accessory compatibility follows from those choices. We do not publish per-model clinic prices or star ratings here.
