Cochlear Nucleus 6 (CP900) Coil Cable Replacement – 8 / 11 / 28 cm

The Cochlear N6 CP900 Series Cable is a replacement coil cable for Nucleus 6 sound processors, the CP910 and the CP920. It carries sound and power from the processor behind your ear to the coil that sits over your implant. It is the thinnest and most flexed part of the whole system, which is why it is also the part Nucleus 6 wearers replace most often.

We stock it in 8 cm, 11 cm and 28 cm, all in black and all at $86. Below you can check the fit for your exact model, read the reference numbers for the CP910 and CP920, spot the early signs of a failing cable, and follow step-by-step fitting and care advice.

Will this Cochlear N6 CP900 Series Cable fit my processor?

Your processor	Does it fit?	What to choose
Nucleus 6 CP910	Yes	This cable in your current length
Nucleus 6 CP920	Yes	This cable in your current length
Nucleus 5 (CP810 / CP802)	Not this listing	Our Nucleus 5 CP810 coil cable
Nucleus 7 (CP1000)	No	Our Nucleus 7 slimline coil with cable
Nucleus Freedom	No	Our Freedom coil cable

To identify your model, look for CP910 or CP920 printed on the processor or in your clinic paperwork. Nucleus 6 processors are often called N6 by wearers and clinics alike, and the family name on most Cochlear documents is the CP900 series.

The coil cable on a Nucleus 6 unplugs from both the processor and the coil, so you only replace the cable, not the coil. If the coil housing is cracked or the magnet no longer holds, that is a separate repair.

Why Nucleus 6 wearers keep a spare cable

Nucleus 6 is now two generations behind the newest Cochlear processor, yet many people still wear it every day and are happy with it. The question that comes up on forums is which N6 parts carry over to a newer processor; wearers report that, apart from some wireless accessories, very little does.

That makes the N6 cable worth protecting. Clinics tend to hold fewer spares for older models, and waiting for one can mean days with no sound on that side. Keeping one spare Cochlear N6 CP900 Series Cable at home and, if you travel, one in your bag, removes that risk for a modest cost.

Bilateral wearers have an extra reason to keep spares. If both processors are Nucleus 6, one spare Cochlear N6 CP900 Series Cable in each length you wear covers either side. If your two sides use different cable lengths, label the spares so you can grab the right one in a hurry.

Signs your Nucleus 6 cable needs replacing

• The sound from your processor comes on and off, especially when you turn your head.
• You notice short dropouts when the cable rubs against a collar or scarf.
• The processor keeps losing contact with the coil and then reconnecting.
• The cable is frayed, kinked or has a white stress mark near a plug.
• Sound fails after rain, a sweaty workout or a humid day, then comes back once dry.
• No visible damage, but a spare cable fixes the problem straight away.

Damage nearly always starts at the ends, where the cable meets the plugs. Bend the cable gently near each plug while listening: if you hear crackling or gaps, the wire inside has started to break.

Wearers often describe a cable that worked fine at home but failed at work or on holiday, because it was already weak and the extra movement of a busy day finished it off. If your cable has started to crackle, it is worth replacing it before a trip, a school term or an important appointment.

How to fit your Cochlear N6 CP900 Series Cable

1. Turn the CP910 or CP920 off and remove it from your ear.
2. Grip the processor-end plug and pull it straight out of the socket.
3. Grip the coil-end plug and pull it straight out of the coil.
4. Lay the old and new cables side by side to confirm the length and which end goes where.
5. Insert the coil end of the new cable into the coil and press until it is fully seated.
6. Insert the processor end into the processor socket and press until it is fully seated.
7. Route the cable in a gentle curve behind your ear, place the coil on your head and switch on.
8. Listen in a quiet room, then turn your head slowly in both directions to check the sound stays steady.

The whole swap takes a couple of minutes and needs no tools. If you are replacing a CP910 cable on one side of a bilateral pair, change only that side first. That way, if sound does not return, you know straight away the fault is not the cable.

Keep the packaging for a few days after fitting your Cochlear N6 CP900 Series Cable. If the cable is defective or the wrong length was sent, we replace or refund it within 14 days.

Nucleus 6 cable troubleshooting

What you notice	Likely cause	What to do
Silence after fitting	One plug not fully pushed in	Remove and re-insert both plugs firmly
Crackling that comes and goes	Worn cable, or moisture on the pins	Fit the new cable and dry the processor overnight
Sound fails only when wet or sweaty	Moisture in the plugs	Dry the processor and cable; replace the cable if it continues
Coil lifts when you turn your head	Cable too short	Move up one length
Loop of cable sticks out	Cable too long	Move down one length
Battery drains fast and sound fades	Ageing battery	Replace the N6 battery

If a new Cochlear N6 CP900 Series Cable and a fully charged battery still give no sound, the coil or the processor needs attention, and your clinic is the right place to check them.

How to make your Cochlear N6 CP900 Series Cable last longer

• Disconnect by the plug every time; pulling the wire is the quickest way to break it.
• Tuck the cable under hair or a collar so it does not snag.
• For children, check the cable daily, as play and car seats put extra strain on it.
• Do not let the cable hang while the processor charges or dries.
• Dry the processor and cable overnight in an electric dryer.
• Keep a travel case so the cable is not crushed in a bag.
• Replace a cable at the first sign of crackling rather than waiting for silence.

A coil cable is a consumable part that wears with daily bending, so planning for regular replacement is normal.

Is a replacement Cochlear N6 CP900 Series Cable safe for my CP910 or CP920?

This is a third-party compatible part, not one made by Cochlear. It has the same plugs, lengths and specification as the cable it replaces, so it connects to the processor and to your current coil in the usual way, with nothing to set up.

Each cable is checked before dispatch. If it is faulty, stops working early, or is the wrong item, we replace it or refund you. Unsure about the fit? Send a photo of your processor and coil on WhatsApp and we will confirm before you buy.

CP910 and CP920 references and choosing a length

Processor	Cochlear reference range
CP910	Z285886–Z285901
CP920	Z299503 series

These ranges cover the different lengths and colours of the Nucleus 6 coil cable. If your old cable bag carries a number in one of them, it confirms you are in the right family; then simply choose the same length.

As a rough guide, 8 cm suits an implant that sits close behind the ear, 11 cm suits one placed further back, and 28 cm is for wearing the processor off the ear. Children may need a longer cable as they grow, so check the fit at each clinic visit. If you have no record, measure your old cable from plug to plug with a soft tape.

Other Nucleus 6 parts you may need

• Nucleus 6 charger – Charge your N6 batteries
• Nucleus 6 microphone covers – Covers with a removal tool
• Electric dryer – Overnight drying for processor and cable

Signs your coil cable is failing

• Sound cuts in and out when you turn your head, bend down or touch the cable.
• The Nucleus 6 processor beeps or shows a coil-off warning even though the coil is on your head.
• You hear crackling, buzzing or sudden silence.
• The cable looks bent, flattened, cracked or discoloured near the plugs.
• A spare cable fixes the problem straight away.

Coil cables are the part that breaks most often on any cochlear implant processor. They bend thousands of times a day, rub on collars and hair, and get pulled when the processor falls off. A worn cable can work most of the day and fail at the worst time, so many users keep a spare Cochlear N6 CP900 Series Cable at home and one in their bag.

How to make the Cochlear N6 CP900 Series Cable last longer

• Unplug the cable by holding the plug, never by pulling the wire.
• Do not wrap the cable tightly around the processor when you store it.
• Keep it away from scissors, pets and young siblings who like to chew.
• Use a clip or soft clothing clip so the processor cannot drop and yank the cable.
• Dry the processor and cable overnight in a drying box if you sweat or live in a humid place.

Choosing the right cable length

The cable must reach from the processor behind your ear to the coil on your head without pulling tight or hanging in a loop. If your current cable feels tight when you turn your head, try the next length up. If it sticks out or catches on glasses, choose a shorter one. Your old cable or your clinic notes usually show the length you use. Children often need a longer cable as their head grows, so check the fit every year.

Travelling with your Nucleus 6

Pack a spare Cochlear N6 CP900 Series Cable in your hand luggage whenever you travel. A broken cable abroad can mean days without sound while a replacement is found. A spare cable weighs almost nothing, fits in a wallet, and is the simplest insurance for a trip, a school camp or a long working week away from home.

• Check the processor model printed on your Nucleus 6 processor body.

Cochlear N6 CP900 Series Cable FAQ

Does it fit both the CP910 and the CP920?

Yes. Both are Nucleus 6 CP900 series processors and both take this cable.

Is the coil included?

No. This is the coil cable only. Your existing coil and magnet stay as they are.

Which length should I order?

The same length you wear now. Check your old cable bag or clinic notes, or measure the old cable from plug to plug.

What do the reference numbers mean?

Z285886–Z285901 is the Cochlear reference range for CP910 coil cables, and the Z299503 series is for the CP920. They help you confirm the part family.

Can I use my Nucleus 6 cable on a Nucleus 8?

Wearers report that very little apart from some wireless accessories carries over from N6 to N8. This cable is for the CP910 and CP920.

Why does my N6 cut out only in humid weather?

Moisture on the plug pins can interrupt the signal. Dry the processor and cable overnight; if it keeps happening, the cable is worn and should be replaced.

How quickly will it arrive?

We dispatch within 24–48 hours, with delivery usually in 12–22 business days.

My child keeps breaking cables. Any tips?

Tuck the cable under hair or a collar, check it each day, and keep a spare at school or with a carer.

What happens if the cable is faulty?

We replace it or refund you if it arrives defective or is the wrong item.

Do I need to pair or program anything after changing the cable?

No. The cable is a passive link between processor and coil. Plug it in at both ends, switch on, and do a listening check.
