Oticon Zeal vs Phonak Lyric 4 – Features Comparison

The Oticon Zeal and the Phonak Lyric 4 are two discreet hearing aid options that sit deep within the ear canal. However, that’s where the similarities between the Zeal and the Lyric 4 end – there are stark differences in terms of features that buyers should consider before making the decision to purchase.

As an audiology practice in Perth, we believe in providing a clear picture of hearing aids, features, and comparisons for buyers to find the right fit. If you are comparing the Oticon Zeal vs Phonak Lyric 4, this in-depth guide will help you make an informed decision. 

Oticon Zeal Hearing Aids Overview

The Oticon Zeal is the latest and most advanced hearing aid device from the Danish manufacturer, released in Australia early 2026. The Oticon Zeal is a Completely-in-Canal (CIC) device with cutting-edge AI sound processing using Oticon’s second-generation DNN (Deep Neural Network) technology. 

The device’s claim to fame is the ability to automatically adjust sound profiles based on the surrounding environment to deliver the clearest listening experience. Examples include being able to easily hear conversations in a busy restaurant or setting without having to focus too hard. 

The Oticon Zeal will also come in multiple versions, with the highest tier model including Bluetooth LE (low-energy) connectivity and direct streaming from entertainment devices. 

Phonak Lyric 4 Hearing Aid Overview

Released in 2020, the Phonak Lyric 4 is an Invisible-in-Canal (IIC) hearing aid device that is highly-rated for its ease of use – with some users claiming that it has changed the way they hear and live. 

The Phonak Lyric 4 is unlike other hearing aids that require daily or frequent recharging – the key feature of the Lyric 4 is that it is designed to be worn 24/7, even while sleeping and showering. Once placed within the ear canal, it operates continuously and does not need to be removed, except to replace batteries (typically after months of use). 

Features Comparison of Oticon Zeal vs Phonak Lyric 4

Sound Quality

The Oticon Zeal is equipped with an AI-processing chip, which is capable of up to 12 dB noise suppression and 6 dB speech clarity enhancement. This same DNN (Deep Neural Network) technology is used in the Oticon Intent – a sister model acclaimed for sound clarity. 

Phonak Lyric 4 delivers an analogue sound instead of a digitally processed sound, resulting in a more open and natural-sounding listening experience. It does not have noise suppression capability, so it loses out in terms of sound clarity. 

The key difference in sound quality will ultimately come down to personal preference. Work with an audiologist who offers trial periods to get a feel for each hearing aid in your everyday environment. 

Comfort and Fit

The Oticon Zeal features a snug fit in the ear canal and is generally comfortable to wear for long periods throughout the day. After the initial hearing aid fitting with the audiologist, users can put in and take out the device on their own without any assistance. 

Phonak Lyric 4 hearing devices must be professionally fitted each time they are put in and removed. Following an initial period of a few days to get used to wearing the hearing aids at all times, it can feel like you are not wearing them at all. 

Battery Life

The Oticon Zeal has a built‑in rechargeable battery designed to last a full day on a single charge, typically around 18–20 hours, depending on streaming functionality. The Zeal also comes with a compact charger that can provide extra battery charge on the go.

The Phonak Lyric 4 can operate continuously for several months, depending on active use. Unlike the Oticon Zeal, however, the Lyric 4 uses a disposable battery, meaning that users must have it professionally removed and maintained when replacement is required. To extend battery life, the Lyric 4 has a ‘Sleep’ mode, where the device reverts the sound to as if users are not wearing a hearing aid. 

Durability

The Oticon Zeal is rated IP68 for moisture and dust resistance, making it safe from sweat, rain, and accidental exposure to water. Users are instructed to avoid extended contact with moisture.  

The Phonak Lyric 4 is water-resistant and can be worn while showering. However, the device is not waterproof – you cannot swim with Lyric hearing aids. 

Connectivity

The Oticon Zeal features Bluetooth LE Audio and Auracast, allowing users to stream music and media directly from devices. This is a big factor for many users who want the convenience of being able to connect directly for entertainment. 

The Lyric 4 has no digital connectivity features – all sound is amplified via analogue technology. 

Application and Controls

The Oticon Zeal has a dedicated smartphone application (Oticon Companion app) where users can control and customise sound profiles, volume, and connection to devices. The app also offers tinnitus support programs designed to mitigate the intensity of tinnitus symptoms. 

While the Phonak Lyric 4 has no digital applications, it does come with a control rod (SoundLync) that allows users to adjust volume or toggle Sleep mode for the device. The SoundLync can be used to adjust the hearing aid while it is being worn.
