Read full reviewThe Sony CRE-C20 is a discreet, over-the-counter hearing aid designed for individuals with mild to moderate hearing loss, featuring a compact size and rechargeable battery for up to 28 hours of use. While it offers a user-friendly setup and an Auto Sound Analyzer for enhanced speech clarity, it lacks Bluetooth streaming capabilities, which may be a consideration for users seeking more advanced connectivity options.
Read full reviewNuance Audio Glasses achieved a SoundScore of 4.13/5 and a SoundGrade of A in HearAdvisor lab testing. It ranked #12 of 61 OTC Hearing Aid devices tested. The OTC Hearing Aid category average SoundScore was 3.47/5.
The Sony CRE-C20 achieved a SoundGrade of B and ranked #21 out of 56 devices in the OTC Hearing Aid category, placing it in the top 36% of OTC devices tested by HearAdvisor. This positions it as an above-average performer within a competitive category.
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.
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.
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.
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.
The Nuance Audio mobile app is user-friendly and available for both iOS and Android devices. It includes useful features such as volume control, microphone directionality, and noise reduction. Nuance hearing glasses are preset-based and use 4 default programs for adjustment, but they are not customizable based on a hearing test.
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.
Nuance Hearing Glasses are comfortable, lightweight, and fit similarly to other broad-rimmed eyeglasses. If you're accustomed to wearing both glasses and hearing aids, you may feel less encumbered since there's no need to fit both glasses and hearing aids on your ear.
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.
Nuance Audio currently offers two frame styles that may appeal to different aesthetic preferences. However, the frames are larger than traditional eyeglasses to accommodate the internal hearing components.
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.
Nuance Audio Glasses has a value score of 3.0/5 based on lab performance and public display price.
The Sony CRE-C20 offers moderate value relative to its $999 price point, with several higher-scoring alternatives available at similar or lower prices.
Nuance Audio Hearing Glasses are easy to use, especially if you're already accustomed to wearing glasses. However, care is required when placing them on the charger, as they must be in a specific orientation to magnetically lock and charge properly.
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.
Nuance Audio Hearing Glasses can be ordered and picked up in-store, where a vision professional will provide basic fitting guidance. Remote technical support is also available online and through the Nuance Audio mobile app. However, remote programming and support from a hearing specialist is not currently offered.
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.
