Naida CI Q90 Ear Hook Replacement

The Naida CI Q90 Ear Hook is a replacement ear hook for the Advanced Bionics Naída CI Q90, the newest processor in the Naída CI Q range. It attaches to the top of the Q90 and wraps over your ear to keep the processor stable through busy days, and it matches part number CI-5710 in small and standard sizes.

Just to be clear, this is for the Naída CI Q90 cochlear implant processor and not the Phonak Naída hearing aid. A Q90 is a valuable piece of equipment, and the ear hook is what stops it from dropping onto a hard floor or slipping off during a run. A fresh Naida CI Q90 Ear Hook restores that secure, comfortable fit for a few dollars.

There is nothing electronic in the Naida CI Q90 Ear Hook. It is a shaped plastic hook that positions the processor so its microphones face forward and the headpiece cable runs neatly to your coil. Replacing it is a two-minute job you can do at the kitchen table.

Will this Naida CI Q90 Ear Hook fit my processor?

Processor	Fits?
Naída CI Q90	Yes
Naída CI Q70	Yes, same hook: Naida CI Q70 ear hook
Naída CI Q30	Yes, same hook: AB Q30 ear hook
Naída CI M90 (Marvel)	No
Advanced Bionics Harmony	No, Harmony uses Auria hooks
Phonak Naída hearing aid	No

The quickest check is the model name printed on your processor casing. Because the Q90 and Q70 share a very similar body, read the label rather than going by appearance. You can also find the model in your clinic paperwork or on the processor box.

If the label has worn away, send a clear photo on WhatsApp and we will confirm the match before you order.

Why keep a spare Naida CI Q90 Ear Hook

The Q90 remains in daily use by many people, and it is worth protecting. One Q90 user on a hearing forum reported paying the equivalent of $1,100 for an off-warranty service. A worn hook that lets the processor fall onto tiles or concrete is an easy way to end up with a repair bill like that.

A spare hook in your processor case or bag means:

• A crack on holiday is fixed in a minute rather than days.
• You can swap to a plain hook instantly if your T-Mic 2 fails.
• Children have a ready replacement at school.
• You never have to wear the processor clipped to clothing while you wait for a part.

Some Q90 users wear a T-Mic 2 every day and only reach for the plain hook in emergencies. One Q90 user on a hearing forum reported replacing their T-Mic once and their headpiece cable twice in about three years, which shows how often small parts wear out over the life of a processor. Having the hook on hand covers you while a T-Mic replacement is on its way.

Signs your Q90 ear hook needs replacing

• The processor shifts every time you smile, chew or turn your head.
• The hook rotates freely on the connector instead of staying put.
• A crack or split appears at the base or along the curve.
• The hook looks yellowed or dull and feels stiff instead of slightly flexible.
• You feel rubbing or pressure behind the ear by the end of the day.
• The processor dropped and the hook now sits at a slightly different angle.

If the processor is moving around, the headpiece cable takes the strain. Users describe sound cutting in and out when they turn their head as a cable problem, but a loose processor is often the trigger. Fitting a new Naida CI Q90 Ear Hook is the first, cheapest step.

A quick monthly check catches most problems early. Take the processor off, hold it under a bright light and look along the whole length of the hook, paying attention to the underside and the base. Then press gently on the hook with your thumb: it should feel firm, with no creak or movement at the connector.

How to attach the Naida CI Q90 Ear Hook

1. Switch off the Q90 and lay it on a soft cloth on a table, so nothing falls far if you drop it.
2. Hold the processor body steady with one hand.
3. Take the old hook by its base and pull it straight off. Do not bend it sideways or use pliers.
4. Look at the connector and remove any lint or residue with a dry cloth.
5. Align the new hook with the connector and press it firmly into place.
6. Check it does not rotate, then put the processor on your ear.
7. Walk around and turn your head a few times to check the fit before switching on.

If you are changing from a T-Mic 2, keep the T-Mic in a clean, dry container so you can refit it later.

New hooks can feel snug the first time they go on, which is normal and shows a good grip. Press straight and firmly rather than wiggling. If it still will not seat, stop and contact us rather than forcing it, since forcing can damage the connector on the processor.

Naida CI Q90 Ear Hook troubleshooting

What you notice	Possible cause	Fix
Processor tips forward off the ear	Hook too large or worn	Try the small size or replace the worn hook.
Tight, pinching feeling	Hook too small	Try the standard size.
Hook loose straight away	Wrong part or damaged connector	Confirm it is the Naída CI Q hook; send us a photo if unsure.
Sound cuts in and out as I move	Processor movement pulling the cable	New hook first; if it continues, replace the Q90 UHP headpiece cable.
Hook keeps breaking at the same spot	Repeated knocks, or wrong size forcing it	Check the size, and use a hard case when not wearing it.
Plastic sticky or discoloured	Cosmetics, sunscreen or sweat	Wipe daily; replace if it stays sticky.

How to make your Naida CI Q90 Ear Hook last longer

• Wipe the hook each evening with a dry, soft cloth.
• Apply sunscreen, hair products and insect spray before putting the processor on, and let them dry.
• Do not leave the processor in a parked car or on a sunny window ledge.
• Store it in a cochlear implant dryer or its hard case overnight.
• Remove the processor before pulling clothes over your head.
• Check the hook for cracks each time you change the battery.

With daily wear, most people replace a hook every few months to once a year.

Moisture also plays a part. Sweat that dries on the hook leaves salts that make plastic harder and more brittle over time. A dry wipe every evening removes most of it, and drying the whole processor overnight helps protect the battery contacts and microphones too.

If you live somewhere hot, or exercise most days, think of the hook as a consumable part and replace it on a schedule rather than waiting for it to crack.

Is a replacement Naida CI Q90 Ear Hook safe for my processor?

Yes. It is a compatible, third-party ear hook made to fit the Naída CI Q90 connector. It is purely mechanical, so it cannot affect your implant, your program or your sound quality. A secure, comfortable fit is all it needs to deliver.

Every hook is checked before dispatch. If yours arrives damaged or is not what you ordered, we replace it or refund you. We are an independent supplier and not connected to Advanced Bionics.

Wearing a Q90 with glasses, masks and helmets

Behind the ear is crowded space. Glasses arms, face mask loops, hats and helmets all compete with the processor and hook.

• Glasses: put the processor on first, then slide the glasses arm in front of the hook. Thin metal arms usually sit more easily than thick plastic ones.
• Face masks: choose masks that tie behind the head, or use a strap extender, so loops do not flick the processor off.
• Helmets and hats: put the helmet on carefully, holding the processor in place, and check the hook is not bent under the strap.
• Sport: the small hook often holds better during running and jumping.

If you often wear a helmet or glasses, a slightly different hook size can make a real difference to comfort.

Children who wear a Q90 face the same challenges at school, often with bike helmets and sports gear. Teaching them to take the processor off before pulling on a helmet, then putting it back on afterwards, saves many broken hooks. Keep a labelled spare in their school bag so a teacher or school nurse can fit it if needed. You can also order a spare Naida CI Q90 T-Mic 2 to keep both options ready.

Naida CI Q90 Ear Hook FAQ

Does the Naida CI Q90 Ear Hook fit the Q70 too?

Yes. The whole Naída CI Q range shares one ear hook part.

How do I ask for the small size?

We ship the standard hook by default. Message us on WhatsApp before ordering if you need small.

Should I use the ear hook or the T-Mic 2?

The T-Mic 2 places a microphone at your ear canal for natural sound and easier calls. The plain hook is tougher and makes a good backup.

My processor keeps falling off during sport. What helps?

Try the small hook, and check it clicks firmly. A sports band can add security.

Can a loose hook damage my cable?

A loose processor puts strain on the headpiece cable, which can lead to dropouts over time.

Is the hook the same colour as my processor?

Colour is shown in the product photo. Message us if you need to check before ordering.

Will the hook fit a Marvel M90?

No. The Marvel processors use different hooks.

How long does an ear hook last?

Typically a few months to a year, depending on sweat, sun and knocks.

Do you ship to my country?

We ship worldwide. Details are in the shipping section below.
