Cearvol Wave vs. Sony CRE-C20

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. 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.

Cearvol Wave achieved a SoundScore of 4.4/5 and a SoundGrade of A in HearAdvisor lab testing. The OTC Hearing Aid category average SoundScore was 3.49/5.

Sony CRE-C20 achieved a SoundScore of 3.7/5 and a SoundGrade of B in HearAdvisor lab testing. It ranked #21 of 63 OTC Hearing Aid devices tested. The OTC Hearing Aid category average SoundScore was 3.49/5.

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.

Sony CRE-C20 has an excellent IP rating of 68, which aligns with our hands-on experience as we observed an improved build quality compared to CRE-C10.

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.

CRE-C20 offer an impressive battery life of up to 28 hours. I also liked the portable charging case which offers you Qi wireless charging.

Cearvol Wave are Bluetooth compatible with both iOS and Android devices, allowing for audio streaming and hands-free calling. The case also offers unique additional wireless features.

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.

Sony's Hearing Control app includes good features and allows your to further personalize CRE-C20 with their on-ear hearing assessment. One downside though is that the hearing aids and app communicate with sound cues from your phone. I find this method of wireless communication less reliable that Bluetooth, and it overall makes the pairing process more complicated.

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.

CRE-C20 are good comfortable once you find the best tip for your ears. They are not overly plugging though it can take some time to get used to having a hearing aid so deep in your ear canal.

Wave offer a modern earbud-like design. This, along with their black and silver color, make them very noticeable in your ears. Depending on your preferences this can be a pro or a con.

CRE-C20 are surprisingly small and sit mostly invisible in your ears. The style works well and was originally designed as an "instant-fit" prescription hearing aid from Signia.

Cearvol Wave has a value score of 4.9/5 based on lab performance and public display price.

Handling is one area where Wave shine. The portable charging case includes a touch-screen and doubles as a wireless remote control for your hearing aids. It also offers additional features like a remote microphone and direct audio input.

CRE-C20's smaller size and method of wireless communication make it more difficult to manage than many other hearing aids. However, Sony has improved upon the design as CRE-C20 now uses internal rechargeable batteries, as opposed to disposable ones. It is a unique offering with many pros but be sure to consider this against your needs and abilities.

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.

Sony does not offer great support with their hearing aids. You are limited to phone and email based technical assistance which is a downside to many OTC products.
