GN Hear & Now



We’re all familiar with the anxiety that comes with programming a hearing aid you’ve never seen before. Fortunately, most hearing aids in our current portfolio can be programmed wirelessly using the Airlink, which makes fittings simple and easy. If a device can be programmed wirelessly, you will see a “W” in the product code e.g. LS961 MP DRW. But if the hearing aid is not wireless, or an Airlink is not available, we must revert to programming hearing aids with cables.
To ease any anxiety you may feel about the unknown, I thought I would put together a guide on the seven different connection types used to program ReSound hearing aids. You’ll find that there are only a handful of connection types used for new and old products, and it is often obvious which one is needed. You can also download a summary of the connections needed for older and newer products below.

​CS44 cables, also known as a standard four pin cable, are the most commonly used cables in clinic. These cables plug into your programming interface (e.g. Noahlink, Speedlink, HiPRO) and any intermediary connections such as flex strips, programming adaptors, programming pills etc.
In addition, the CS44 cable plugs directly into a few older ReSound hearing aids as shown below. Hearing aids that use this connection include all Sparx, Essence, Metrix, Pixel and Plus5 BTE devices, and some Azure, X-Plore and Ziga BTE devices. Keep in mind that you will need to open a cable cover on 70 and 80 model hearing aids to plug in the CS44 cable.
​Left to right: CS44 cable plugs directly into 60 models, you will need to open a cable cover before plugging the CS44 cable into 70 & 80 models.


​This connection style is used for most BTE and RIE devices. A good way to check if your hearing aid requires a programming adaptor is to look at the belly of the hearing aid and check for contacts.
​If your device has contacts like the one shown above, you will require a programming adaptor. The most popular adaptor is gray in colour and is used on BTEs and RIEs in the Azure, X-Plore, Ziga, Ziga Lite, Live, Alera, Verso, Linx, Linx2, Enzo2 and Enya families.
A beige adaptor is only required for Vea and Magna hearing aids. You can see that these hearing aids require a different programming adaptor because the contacts are much large
​Magna hearing aids have a contact cover which you must slide to the side before connecting the beige programming adaptor.


CS53s, also known as flex strips, are also commonly used to connect ReSound products. CS53s have three golden contact strips which must be inserted into the housing of a hearing aid.
This connection type is used to connect all ITEs, ITCs and CICs (except Canta) where the CS53 is inserted in the hinge of the battery door as shown below.
​We also use this connection for some RIE and BTE devices including the Pulse, Air, Dot, Dot2, and Alera 60 and 61 models as shown below.

​This particular connection is only used for the Lex and Be instant fit hearing aids. You must insert the pill just like you would a battery, and then close the battery door.


​This connection type is only used for our super power Enzo and Enzo2 98 model devices. You must slide the battery door pin out of the device, remove the battery door and attach the programming door using the battery door pin.


This connection type is used for all IICs. The IIC programming pills are red and blue in colour and will connect directly to your programming interface without the need for a CS44 cable. 
​You must remove the battery door of the IIC before inserting the programming pill into the device. If you’re worried about this, you can order an IIC battery door removal tool to help you.
Open battery door and insert removal tool in the battery door as if it is the battery. Align it as shown, then close the battery door with the removal tool. The battery door should pop off the hinge.


This connection type is only used for Canta devices as shown below. CS64 cables look similar to a CS53 flex strip although they are not interchangeable due to a different number of contact strips. ​
Lastly, all programming connections and tools can be ordered from or through your ReSound area manager. And if you have any trouble connecting devices, please feel to call our technical support line on 1800 658 955 or email us at
