Oticon released Oticon Zeal NXT, an easy-fit, rechargeable, invisible Bluetooth and Auracast, which holds the same level of AI and DNN processing as its flagship Oticon Intent. It is quite a powerhouse in a miniature size. Read this article to learn more about Oticon Zeal hearing aids and it's features.
What are the highlights of Oticon Zeal hearing aids?
The Oticon Zeal NXT comes loaded with the best features that you can find in other hearing aids in the market. A short list of Oticon Zeal's features is:
Same-day fitting and flexibility: Oticon Zeal can be fitted with the same range of Oticon present open, closed and power domes. This enables the agility of a quick fit in a single visit to the clinic. I love the flexibility that they can also take a custom micromould for people with irregular, very large or those who have experience retention issues with hearing aids.
Discreet and comfortable: The size of the Oticon Zeal is a tad bigger than that of a CIC hearing aid. I cannot say that it would fit better than a custom-made CIC, but Oticon claims that the majority of the people who tried Oticon Zeal were happy with the size of them, being almost invisible. Again, this is something you'd better check in the clinic, especially the antenna, which is likely to be noticeable. As stated by Oticon, this is a new category of hearing aids which is bigger than CIC but smaller than ITC (e.g. Phonak Virto Infinio ITC).
Next-generation AI: I am impressed to see that the processor used in Oticon Zeal is exactly the same chip which is used in Oticon Intent. The AI sound processing technology delivers up to 12 dB noise suppression and AI-driven speech clarity enhancement up to 6 dB.
Superior connectivity: Oticon Zeal supports ASHA Bluetooth for connectivity to iPhone and Android mobile phones, as well as LE Audio and Auracast. This offers the utmost sound quality and battery saving. Oticon Zeal does not support Telecoil. I think we can compromise that one. Also, Oticon Zeal is the first hearing aid enabled for Google's Fast Pair: users can pair their hearing aid effortlessly with Android phones. Once paired, their connection is automatically recognised across other Android devices logged into the same Google account. Oticon is targeting the Android mobile sector with such a move.
Descent battery life: It takes only 2 hours to go from full charge. A fully charged Oticon Zeal offers 20 hours of run time with 4 hours of streaming. The charging technology enables quick power-ups, providing 4 hours of use with just 15 minutes of charging, or 8 hours of use with a 30-minute charge.
How is the sound quality of Oticon Zeal?
Oticon Zeal uses the same processor and speaker unit as Oticon Intent miniRITE hearing aids. So for the first time, you can enjoy the sound quality of a RIC hearing aid in a small CIC size hearing aid by Oticon.
Who would benefit from the Oticon Zeal hearing aid?
I believe that the following groups of patients could benefit from Oticon Zeal NXT hearing aids:
First-time users of hearing aids who wish to try a pair of hearing aids which look like music earbuds with full Bluetooth connectivity, Auracast and streaming.
Patients who are emotionally not prepared or comfortable to use behind the ear RIC models.
Those long-term patients who are looking for the cutting-edge in the canal technology, rechargeable, Bluetooth streaming and AI-DNN sound processing.

What level of hearing loss can Oticon Zeal support?
Oticon Zeal comes with a size speaker unit, which is 75 dB. That enables the hearing aid to support a flat or sloping mild to moderate to severe hearing loss. For severe hearing loss, you might need to use custom earmoulds.
Do Oticon Zeal hearing aids use Oticon BrainHearing technology/
Yes. Trained on 12 million sounds, Oticon Zealâ„¢ uses second-generation AI to identify and prioritise speech over background noise, making conversations easier.
Is Oticon Zeal truly a CIC hearing aid?
I wouldn't say that. Oticon called the Oticon Zeal an NXT generation, basically creating a new category for small-sized canal hearing aids. It might be comparable in size to Starkey Edge AI 312 CIC, which also has Bluetooth.
What are other hearing aids similar to Oticon Zeal?
The closest hearing aids that I can think of to Oticon Zeal are:
Starkey Edge Ai 312 CIC, which same as Oticon Zeal, has Bluetooth, but a. it does not have LE Audio, Auracast, and it is not rechargeable. But it is a custom design.
Signia Silk and Rexton Reach inoX rechargeable CIC. Both models are rechargeable and smaller than Oticon Zeal, but have no Bluetooth or streaming capability.
How good are Oticon Zeal hearing aids in noise management?
According to Oticon, the Oticon Zeal uses the same level of AI and DNN sound processing as Oticon Intent, so the sound of it should be impressive. I will report on this page as soon as I receive a trial set to try them myself. One thing to note is that, similar to other IIC and CIC hearing aids, Oticon Zeal only has one microphone. Nevertheless, the virtue of AI processing can provide a natural hearing experience, especially since the microphone is located in the concha and not top of the ear.
How secure is Oticon Zeal in the ear?
In my experience, more than 70% of the patients use the hearing aids with silicon domes and have no retention issues. However, the other 30% might need hearing aids to be fitted with custom earmoulds. It is a relief to know that I can make micromoulds for Oticon Zeal for better retention for my patients.
Can I do hands-free phone calls with Oticon Zeal hearing aids?
Yes. You can do audio streaming and hands-free phone calls through your Oticon Zeal NXT hearing aids. Amazingly, you can have your Oticon Zeal pick up a phone call by double-tapping on either of the aids.
