Quick Answer: A hearing aid ear hook is the rigid curved piece on a behind-the-ear (BTE) device that loops over your ear and holds the sound tubing in place — a different part from the soft tubing itself. Hooks are sized by number (most commonly 1 to 3, plus pediatric versions) and sometimes by damped vs. undamped filtering, and they’re brand- and often model-specific rather than truly universal. The biggest trap when shopping: a plain “hearing aid ear hooks” search pulls in silicone domes and unrelated Bluetooth-headset ear clips alongside the real part, so check that you’re buying a BTE hearing aid earhook specifically, matched to your device’s size and damping code.
If your BTE hearing aid has started whistling, feels loose behind your ear, or the curved plastic piece at the top has gone yellow and brittle, the ear hook — not the tubing threaded through it — is often the real culprit. It’s an easy, inexpensive fix once you know what you’re actually shopping for, which is the hard part: this is one of the few hearing aid accessories where the generic search results are mostly the wrong product. This guide covers real ear hook sizing, the damped-vs-undamped distinction, and brand-matched picks for the most common BTE platforms.
Ear hooks by the numbers
- Sizes 1 to 3 cover most adult BTE fittings, with size 2 or 3 the most common fit, per hearing aid accessory guidance — smaller, dedicated pediatric hooks exist separately for children’s ears.
- Standard, pediatric, damped, and undamped are the four variant types Oticon alone offers across its BTE earhook lineup, which is typical of how granular sizing gets once you move past “one size fits all.”
- 70% to 80% of hearing instrument failures trace back to cerumen (earwax) and moisture, per the Hearing Review — a cracked or wax-clogged ear hook is exactly the kind of cheap, overlooked part behind a chunk of that figure, not a circuit failure.
- Roughly $5 to $9 each is the typical price range for a brand-matched replacement earhook from a hearing aid accessory retailer, based on current UK audiology-parts pricing converted to USD — far cheaper than a clinic repair visit.

1. Generic/Universal Replacement Ear Hooks — Best for Budget OTC BTE Devices
Generic Replacement BTE Ear Hooks (multi-pack)
- The closest thing to a true "universal" option, and realistically the right fit for lower-cost OTC amplifier-style BTE devices that use a simpler, less proprietary shell than prescription-grade aids.
- Sold in small multi-packs with a few sizes included, so you can test fit without committing to one size blind.
- Not a safe bet for a major prescription brand's BTE model — those still need a brand-matched hook, covered below.
If you’re also restocking domes, wax guards, or batteries for the same device, try Amazon Prime free for 30 days — it turns a small accessory reorder into two-day shipping instead of a week’s wait.
2. ReSound/Jabra Enhance-Compatible Ear Hooks — Best for ReSound-Platform Models
ReSound-Compatible BTE Earhook
- Matched to ReSound's BTE shell, which also covers Jabra Enhance Select since it runs on GN's shared ReSound hardware platform.
- Sold in separate adult and child sizes, with standard and large plastic variants for different ear shapes.
- Order through your audiologist or a hearing aid accessory retailer if you don't see an exact match on general marketplaces — these are lower-volume parts than batteries or domes.
3. Oticon BTE Ear Hooks — Best for Oticon Models
Oticon BTE Earhook
- Oticon sells four distinct variants across its BTE range — standard and pediatric for fit, damped and undamped for sound filtering — so matching the full code on your current hook matters, not just the size number.
- A damped hook filters out specific frequency peaks before sound reaches your ear; swapping to undamped (or vice versa) changes your sound, not just your fit.
- Available for multiple Oticon BTE ranges including newer Opn and Xceed-family devices, per Oticon's own parts documentation.
4. Phonak Colored Ear Hooks — Best for Phonak Models
Phonak BTE Ear Hooks
- Phonak sells its BTE ear hooks in several colors in addition to sizes, which doubles as a quick way for a caregiver to visually confirm the correct hook is on the correct ear or device.
- A different part from Phonak's 4.0 Retention Locks, which solve a receiver-in-canal (RIC) fit problem rather than a BTE hook issue — see our retention wire guide if your device is RIC, not BTE.
- Confirm your exact Phonak BTE model before ordering, since hook compatibility runs by shell generation.
The naming trap: why most search results aren’t the right product
Search for “hearing aid ear hooks” on a general marketplace and you’ll get three different products tangled together: real BTE hearing aid earhooks, silicone hearing aid domes (a different part that seals in the ear canal, not the piece that loops over your ear), and ear hooks/clips made for Bluetooth headsets and earbuds that have zero connection to hearing aids at all. Only the first one is what this guide covers. Before you buy, check that the listing specifically says “hearing aid” and “BTE,” not just “ear hook” — the generic term alone is too broad to trust.
Damped vs. undamped: the fit that’s easy to miss
Size isn’t the only variable. Some brands, Oticon among them, sell the same hook in damped and undamped versions: a damped hook has a small acoustic filter built in that tones down specific frequency peaks, while an undamped hook lets sound through unfiltered. Your audiologist chose one or the other when your hearing aid was originally fitted, based on your hearing profile — swapping the damping level without knowing it can change how your hearing aid sounds even when the hook clicks on perfectly. If your current hook doesn’t have a visible code, ask your audiologist which version you’re replacing rather than guessing from the size alone.
A quick health note
An ear hook is a wear part, not a hearing solution, and a cracked or wrong-size hook won’t fix sound quality issues caused by a bad dome fit or an outdated fitting. OTC hearing aids are intended for adults 18 and over with perceived mild-to-moderate hearing loss. If swapping the hook doesn’t resolve whistling or a loose fit, or if you have ear pain, drainage, sudden hearing changes, or hearing loss in only one ear, see an audiologist rather than continuing to troubleshoot with accessories.
The bottom line
Match the hook to your device’s brand and exact size/damping code, not the word “universal” in a listing title: a generic multi-pack is a reasonable bet for budget OTC amplifier-style BTE devices, while ReSound/Jabra Enhance, Oticon, and Phonak owners should look for their brand-matched hook specifically. Watch for domes and Bluetooth-headset clips cluttering your search results — none of those are the part you need.
