3.4AVERAGE

The 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.

Build Quality

Hearing Glasses
3.9BELOW AVERAGE

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.

CRE-C20
4.8EXCELLENT

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.

Battery

Hearing Glasses
1.9BELOW AVERAGE

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
4.4ABOVE AVERAGE

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.

App Features

Hearing Glasses
3.5BELOW AVERAGE

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.

CRE-C20
3.0BELOW AVERAGE

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.

Comfort

Hearing Glasses
4.5EXCELLENT

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
4.0AVERAGE

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.

Design

Hearing Glasses
5.0EXCELLENT

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
5.0EXCELLENT

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.

Value

Hearing Glasses
3.0BELOW AVERAGE

Nuance Audio Glasses has a value score of 3.0/5 based on lab performance and public display price.

CRE-C20
3.3BELOW AVERAGE

The Sony CRE-C20 offers moderate value relative to its $999 price point, with several higher-scoring alternatives available at similar or lower prices.

Handling

Hearing Glasses
5.0EXCELLENT

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
4.0AVERAGE

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.

Pro Support

Hearing Glasses
1.0BELOW AVERAGE

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.

CRE-C20
1.0BELOW AVERAGE

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.

Software Features

CRE-C20
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.

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.
