Cearvol Wave vs. Phonak Audéo EON

Cearvol Wave is an affordable earbud-style OTC hearing aid with Bluetooth streaming, self-fitting controls, wired audio input, and a touchscreen charging case. Current lab results show useful speech benefit and good music streaming, with a B SoundGrade. Shorter runtime, a plugged-up own voice, and remote-microphone delay are its main compromises.

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.

Cearvol Wave achieved a SoundScore of 3.9/5 and a SoundGrade of B in HearAdvisor lab testing. It ranked #22 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.

We found Cearvol Wave to feel well built, especially the portable charging case, though they have a lower IPx5 rating. This suggests you should take extra care and limit exposing them to moisture and debris.

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

Wave's battery life falls below many other hearing aids with a max use time of up to 10 hours per charge. You can expect shorter run times in their Restaurant program and with heavy use of Wave's wireless audio features. While this could be better, Wave offer a quick-charge feature where 15 minute in the case gives you an additional 3 hours of use.

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.
