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.
Read full reviewThe Signia Silk Charge&Go IX is a groundbreaking, rechargeable completely-in-canal (CIC) hearing aid designed for people with mild to moderate hearing loss.

Read full reviewCearvol Wave achieved a SoundScore of 4.37/5 in HearAdvisor lab testing. The OTC Hearing Aid category average SoundScore was 3.47/5.
Signia Silk Charge&Go IX achieved a SoundScore of 3.70/5 and a SoundGrade of B in HearAdvisor lab testing. It ranked #25 of 35 Prescription Hearing Aid devices tested. The Prescription Hearing Aid category average SoundScore was 3.91/5.
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.
Signia Silk C&G IX have an impressive build quality, featuring a top-of-the-line IP68 ingress rating, which is crucial for nearly invisible hearing aids. They also come with a durable portable charging case.
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.
Silk IX provide up to 20 hours of use per charge which is exceptional given their extremely small size. Recharging takes up to 4 hours, which is longer than some other models, but this isn't a significant drawback given their all-day battery life.
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.
While Silk IX hearing aids are not Bluetooth compatible, they still work with Signia's app using high-frequency coded signals. This is a valuable addition, although the communication is less stable than Bluetooth and the app offers fewer features compared to other Signia models.
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.
I found Silk IX very comfortable for an instant-fit nearly invisible hearing aid. Your hearing care provider should ensure they are fitted for optimal comfort and hearing benefit.
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.
Silk IX is another unique offering from Signia, featuring an instant fit design with silicone ear tips that is nearly invisible. Its extremely small and discreet design may, however, pose challenges for those with limited dexterity and or vision.
Cearvol Wave has a value score of 4.9/5 based on lab performance and public display price.
Signia Silk Charge&Go IX has a value score of 2.4/5 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.
I did not run into any issues while using Silk IX hearing aids. They are very easy to use once setup by your hearing care provider. Silk also have large color indicators making it easy to distinguish the left from the right hearing aids.
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.
You should receive quality hearing care and support from your provider. The Signia App should further enhance your experience with AI help and remote assistance should your provider offer telehealth services.
