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.

Pure Charge&Go MaX
4.9EXCELLENT

Pure MaX have an impressive build quality, featuring a top-of-the-line IP68 ingress rating. I also found their portable charging case robust, though on the larger size.

Battery

Hearing Glasses
1.9BELOW AVERAGE

Nuance Hearing Glasses use internal lithium-ion batteries that provide up to 8 hours of use. To extend battery life throughout the day, Nuance recommends using them situationally and turning them off when not needed. Recharging takes approximately 3 hours.

Pure Charge&Go MaX
4.4ABOVE AVERAGE

Pure Max hearing aids have a reported battery life of around 30 hours per charge. While less than Signia's previous Pure C&G device, it is still plenty to get you through the day. Recharging takes 3 to 4 hours which can be done overnight while you sleep.

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.

Pure Charge&Go MaX

Signia's app stands out with its user-friendly interface and modern, appealing design. It includes practical features like the ability to control the focus of your hearing aids and a mask mode to enhance speech clarity. Additionally, the app offers wellness features, utilizing hearing aid motion sensors for activity tracking.

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.

Pure Charge&Go MaX
5.0EXCELLENT

I found MaX very comfortable due to their shape and earwire design. Your hearing care provider should ensure they are fitted for optimal comfort and hearing benefit before you leave the office.

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.

Pure Charge&Go MaX

Handling

Hearing Glasses
5.0EXCELLENT

Nuance Audio Hearing Glasses are easy to use, especially if you're already accustomed to wearing glasses. However, care is required when placing them on the charger, as they must be in a specific orientation to magnetically lock and charge properly.

Pure Charge&Go MaX
4.5EXCELLENT

I did not run into any issues while using MaX hearing aids. They are very easy to use once setup by your hearing care provider. First-time users may need some practice to get accustomed to inserting the receiver-in-ear style properly.

Pro Support

Nuance Audio Hearing Glasses can be ordered and picked up in-store, where a vision professional will provide basic fitting guidance. Remote technical support is also available online and through the Nuance Audio mobile app. However, remote programming and support from a hearing specialist is not currently offered.

Pure Charge&Go MaX
