Nuance Audio Hearing Glasses vs. Phonak Audéo EON

Nuance Audio Glasses seamlessly combine prescription eyewear with discreet over-the-counter hearing enhancement, offering solid performance in speech clarity but with some limitations in battery life and audio streaming.

The Phonak Audéo Eon is 25% smaller and 20% lighter than the outgoing Sphere, and it adds Auracast support and stronger wind noise reduction. The family includes three device models, the Eon Sphere, Eon R, and CROS Eon.

Nuance Audio Glasses achieved a SoundScore of 3.9/5 and a SoundGrade of B in HearAdvisor lab testing. It ranked #20 of 65 OTC Hearing Aid devices tested. The OTC Hearing Aid category average SoundScore was 3.68/5.

Phonak Audéo EON Sphere achieved a SoundScore of 5.0/5 and a SoundGrade of A in HearAdvisor lab testing. It ranked #1 of 39 Prescription Hearing Aid devices tested. The Prescription Hearing Aid category average SoundScore was 4.19/5.

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.

Phonak Audéo E90 Sphere have an excellent build quality with a robust, portable charging case and a high ingress rating of IP68.

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.

Audéo EON offer around 38 hours of use per change, which is a decrease compared to the previous firmware-upgraded Sphere Ultra. Regardless, the battery life should span your entire day and a full recharge takes 3 to 4 hours, or 30-minute quick charge can provide an additional 6 hours of use.
