4.4ABOVE AVERAGE

The Cearvol Wave is a budget-friendly OTC hearing aid with a visible in-ear design, Bluetooth streaming, app-based personalization, AUX-IN support, and a charging case that can double as a remote microphone. In HearAdvisor lab testing, it earned a strong 4.32/5 SoundScore, with especially impressive speech-in-noise performance for its $399 price. The main trade-off is own-voice comfort, where users may notice a more plugged-up or boomy sound. A full HearingTracker review is still pending.

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.

2.7BELOW AVERAGE

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.

We found the Cearvol mobile app to offer many useful features for general sound customization. The user-interface could be modernized, though the large numbers and icons make it easier to see what you are adjusting.

I found Wave comfortable to wear with a nice "twist-in" feel. My main complaint is that they protrude slightly from the ear which can make them more prone to catching on things.

Cearvol mention offering both remote and online support from hearing care providers. You also have 24/5 access to their support specialists. In my experiences, they are quick to respond and you can easily receive help from a human.

Software Features

Adjustment BandsAdjustment BandsThese are frequency-divided sections that can be adjusted in a hearing aid in order to amplify sounds. Although there are rarely more than 10 frequencies measured in a hearing assessment, having more bands that can be adjusted may allow for improved speech understanding and user comfort.

Adjustment SynchronizationAdjustment SynchronizationThis feature allows for a more pleasant listening experience by ensuring that both hearing aids process sound the same way. If one hearing aid changes its processing in response to noise or speech, it will send a wireless signal to the other hearing aid so both process sound in the same way.
No
Yes
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.
