Build Quality

Hearing Glasses
3.9BELOW AVERAGE

Nuance Audio Hearing Glasses have an IPX4 rating, which means they can withstand light splashes of water but may require extra care to ensure long-term reliability. Fortunately, their delicate components are less susceptible to moisture damage since they aren't positioned inside the ear like traditional hearing aids.

I found Zeal to offer easy and stable wireless connection. Their audio quality while streaming music, and during hands-free calling, was good and comparable to other prescription hearing aids.

App Features

Hearing Glasses
3.5BELOW AVERAGE

The Nuance Audio mobile app is user-friendly and available for both iOS and Android devices. It includes useful features such as volume control, microphone directionality, and noise reduction. Nuance hearing glasses are preset-based and use 4 default programs for adjustment, but they are not customizable based on a hearing test.

Zeal
5.0EXCELLENT

I found the Companion app easy to navigate and use. Other prescription hearing aid companies offer more in-depth health features, but there is still plenty of opportunity to customize settings from your mobile device. The HearingFitness component is also a nice feature for those who like to actively track their progress.

Comfort

Hearing Glasses
4.5EXCELLENT

Nuance Hearing Glasses are comfortable, lightweight, and fit similarly to other broad-rimmed eyeglasses. If you're accustomed to wearing both glasses and hearing aids, you may feel less encumbered since there's no need to fit both glasses and hearing aids on your ear.

Zeal
4.8EXCELLENT

Oticon Zeal were extremely comfortable and lightweight in my ears. In general, hearing care providers can make numerous physical changes to prescription hearing aids like Zeal to improve comfort.

Design

Hearing Glasses
5.0EXCELLENT

Nuance Audio currently offers two frame styles that may appeal to different aesthetic preferences. However, the frames are larger than traditional eyeglasses to accommodate the internal hearing components.

Zeal
5.0EXCELLENT

Zeal are sleek, easy to use, in-the-ear prescription hearing aids. They are nearly invisible in the ear which is extremely impressive given their battery life and wireless capabilities.

Better Ear FocusBetter Ear FocusSome modern hearing aids can share sound from one ear to the other. In some cases the sound from the less noisy side can be shared to the other ear, enabling the listener to hear a cleaner sound in both ears.

DirectionalityDirectionalityDepending on the types and number of microphones a hearing aid has, the hearing aid may be able to boost sounds from specific directions (by reducing sounds from other directions). This can be helpful to focus on a speaker directly in front of the hearing aid user, as well as to give the user information about where different sounds are coming from.

Clear DynamicsClear DynamicsClear Dynamics expands the input dynamic range, processing input sounds up to 113 dB SPL, to provide better sound quality without distortion and artifact at loud input levels, while still keeping the sound quality of soft input levels intact. Clear Dynamics has an operating range from 5 to 113 dB SPL. With speech cues preserved at high input levels, users enjoy a better listening experience without distortion even in loud environments. Clear Dynamics is especially valuable for users when listening to music or in conversations in busy, dynamic environments, where peaks can often be louder than the available input dynamic range.
Feedback SuppressionFeedback SuppressionIf any sound amplified by the hearing aid escapes the ear canal, it may reach the hearing aid’s own microphone and cause a harsh whistling noise. Some hearing aids are able to recognize when this feedback occurs and reduce or eliminate it.
No
