As an audiologist who has worked with cochlear implants since 1984, I have seen technology explode – particularly in recent years. I find it amazing to witness how patient performance has improved alongside these technology advancements. In the early days of cochlear implants (CI), we hoped that patients could distinguish presence vs. absence of sound and maybe tell the differences between speech and environmental noise. Today, patients are now able to talk on the phone, carry on conversations in noisy environments and connect wirelessly to everyday devices with their CI. If you had told me 20 years ago that my patients would enjoy wirelessly streaming music – I would not have believed you.
So I was intrigued when Cochlear asked if I would be willing to fit their newest sound processor—the Kanso™ — on patients.
From my perspective, recipients want things to be simple, easy to use and effortless. I found this to be true when fitting the Kanso. Recipients were impressed with the ease of use—only one button to push and they were ready to go! My patients have enjoyed the automaticity of the device, including the automatic scene classification offered by SCAN*.
When counseling on device choice during the candidacy process, I saw patients quickly gravitate toward an off-the-ear option. In fact, their “eyes would light up” at first glance. As a center that offers two sound processors, this was a nice opportunity to offer recipients the wearing flexibility to have an off-the-ear option and a behind-the-ear option as their product selections.
My next question was “can this device deliver on performance”? I wanted to verify that this very simple off-the-ear device was equivalent to the Nucleus 6 sound processor that I have been fitting successfully for the past several years. Kanso offers dual microphones, SmartSound™ IQ* and access to the same wireless technology as the N6 sound processor. This is a truly remarkable innovation. In fact, I found that recipients wearing the Kanso demonstrated essentially comparable hearing experience¹ to that of their current N6 sound processor.
To my surprise, retention of the device was not an issue with most of the recipients I fit. I found that if the recipient was extremely active, using the very transparent retention wire assisted with any concerns that the device may fall off when used during a particular activity.
There was a definite reduction in the time it took to counsel on the device use, wear, and care during the initial fitting. This was particularly nice for my recipients as the information that I needed to provide on the device operation was straightforward, easy to understand and not overwhelming to them, which is not always the case! So because of the reduction in time, I was able to focus on other aspects of the fitting process like rehabilitation and use of the wireless accessories. 
A final question I always ask myself is “would I wear it?” And that answer is “absolutely!” To me it is important that when I make a recommendation to recipients that it is one that I can personally stand behind which is unequivocally the case with the Kanso. It is truly an extraordinary product that offers great flexibility and is discreet and easy to use for adult and pediatric patients alike.
