Quick Answer: For most receiver-in-canal (RIC) hearing aid wearers, the best retention wire is a brand-matched Sports Lock or Retention Lock — a soft silicone dome that clips onto the receiver wire and wedges into the outer ear to stop the aid from working loose during exercise, sleep, or an active day. Jabra Enhance Select owners should look for GN ReSound-compatible Sports Locks (about $15–$16 for a 10-pack), since Jabra Enhance runs on ReSound’s hardware platform; Oticon, Phonak, and Starkey each sell their own matched locks, running roughly $12–$26 depending on brand and pack size. These are different from a retention clip or cord, which tethers the whole hearing aid to your collar as loss insurance rather than holding the receiver seated in your ear.
A RIC hearing aid’s tiny receiver sits loose in your ear canal, held in place mainly by a silicone dome and friction — which is exactly why it’s the style most likely to work its way out during a run, a workout, or a restless night’s sleep. A retention wire fixes that at the source instead of just catching the aid after it’s already fallen: a small silicone lock clips onto the receiver wire itself and grips the bowl of your outer ear for extra hold. This guide covers the best brand-matched retention wires of 2026 and how they differ from a retention clip.
Retention wires by the numbers
- $12–$26 is the typical price range for brand-matched retention locks in 2026, per hearing aid accessory retailers — Phonak’s 4.0 Retention Locks run about $12, Oticon’s MiniFit Ear Grips and GN ReSound’s Sports Locks run about $15–$16, and a 20-pack of Starkey Sports Locks runs about $26.
- $150–$500 a year is what third-party loss-and-damage coverage typically costs once a hearing aid’s one-time manufacturer replacement is used up, according to providers like ESCO — a retention wire won’t replace that coverage, but keeping a receiver seated correctly cuts how often it ever comes to a claim.
- Jabra Enhance Select, the site’s top-ranked OTC pick, runs on GN ReSound’s hardware platform (confirmed with the Select 700’s 2025 ReSound-Vivia-based redesign) — which is why ReSound-branded Sports Locks are the compatible choice for that device rather than a generic universal lock.

1. GN ReSound Sports Locks — Best Overall / Best for Jabra Enhance
GN ReSound Sports Locks (SureFit 2/3 Receiver)
- Small silicone locks click onto the SureFit receiver wire and add grip inside the concha, so the aid stays seated through a workout, a run, or a night's sleep.
- Compatible with Jabra Enhance Select devices, since Jabra Enhance is built on GN's shared ReSound hardware platform — the same lock that fits a ReSound receiver fits the matching Jabra Enhance receiver.
- Sold in a 10-pack because the silicone wears out with regular wear; budget for a replacement pack every few months of daily use.

2. Oticon MiniFit Ear Grips (Sport Locks) — Best for Oticon
Oticon MiniFit Ear Grips (Sport Locks)
- Oticon's own matched retention lock for its MiniFit receiver line, sized to click on without needing a universal or generic fit.
- Designed for the same active-use case as ReSound's Sports Locks — sweat, movement, and sleep are the three scenarios most likely to dislodge a RIC receiver.
- Check your Oticon model's receiver size/power code before ordering, since Oticon sells the grips in multiple matched sizes.
3. Phonak 4.0 Retention Locks — Best for Phonak
Phonak 4.0 Retention Locks
- Matched to Phonak's 4.0 receiver wire across several recent Phonak generations, so one lock family covers multiple device lines.
- The lowest per-unit price of the brand-matched options in this roundup, which matters since these are a recurring consumable rather than a one-time purchase.
- Phonak also sells colored ear hooks separately for BTE-style Phonak aids, which solve a related but different fit issue than a RIC retention lock.
4. Starkey Sports Locks (20-pack) — Best Value / Bulk
Starkey Sports Locks / Retention Locks
- The largest pack size in this roundup at 20 locks, which brings the per-unit cost down for anyone who wears their aids through daily workouts or works outdoors.
- Matched specifically to Starkey's receiver line — like the other brand-specific picks here, confirm your exact Starkey model before ordering.
- A practical stock-up buy if you've already confirmed fit with a single pack and just need to keep a running supply on hand.
Retention wire vs. retention clip: which do you need?
They’re not competing products — they protect against different failure points. A retention wire/lock keeps the receiver seated correctly inside your ear, which is a fit problem: it reduces how often a RIC aid works loose in the first place. A retention clip or cord (see our best hearing aid clips guide) is loss insurance for after that happens anyway: it tethers the whole aid to your collar so a dislodged device dangles instead of vanishing. Anyone who’s active, sweats regularly, or has had an aid pop loose during exercise gets the most value from running both together — a lock to reduce the problem, a cord to catch the rare failure.
Before you buy: match the receiver, not just the brand
Retention locks are sized to a specific receiver wire and power level, not to your ear or even just your hearing aid’s brand name. Two things to check before ordering:
- Find your receiver’s size/color code. Most receiver wires have a small printed number or colored dot near the connector — that code, not the hearing aid’s model name, is what determines lock compatibility.
- Confirm with your audiologist or the OTC brand’s support line if you’re unsure. A wrong-size lock either won’t click onto the wire or will feel loose and fail to add any real grip, so it’s worth one quick check before buying.

A quick health note
A retention wire is a fit accessory, not a treatment, and it won’t fix a hearing aid that’s uncomfortable because of the wrong dome size or a poor initial fitting. OTC hearing aids are intended for adults 18 and over with perceived mild-to-moderate hearing loss. If your aid consistently won’t stay seated even with a matched lock, or if you have ear pain, drainage, sudden hearing changes, or hearing loss in only one ear, see an audiologist rather than relying on an accessory to compensate.
The bottom line
Match the lock to your receiver, not just the hearing aid brand on the box: GN ReSound Sports Locks are the right call for Jabra Enhance Select owners since it shares ReSound’s hardware platform, Oticon MiniFit Ear Grips and Phonak 4.0 Retention Locks cover their respective brands at $12–$15 each, and a Starkey 20-pack is the best value if you’re stocking up. None of these replace a retention clip if loss — not just fit — is your worry; see our best hearing aid clips guide for that separate problem.
