Your OTC hearing aid will arrive preinstalled with size S (small) click sleeves. If these aren’t comfortable, you can switch to one of the other three sizes provided (XS, M, L). Choose a smaller size if the hearing aid is pressing on your ear or a larger size if the hearing aid feels loose or makes a whistling noise. Also, your left and right ear may be slightly different sizes, so feel free to use different size sleeves in each ear. Check the User Guide or watch these instructional videos to learn how to insert, fit, and remove your hearing aids.

When you’re not wearing your CRE-E10 OTC hearing aid—like when you take it out before bed—you should set it in the charger. Once placed in the charger, the power will turn off, and the hearing aid will begin charging.

You will need an Apple® iPhone® device (iOS™ 13 or higher) or an Android™ smartphone (Android OS 10 or higher) with the Sony Hearing Control app² installed to perform hearing aid fitting and volume adjustment. 

The Sony Hearing Control app² version 1.1 is now available and adds support for:

• iPhone 7, iPhone 8, iPhone SE 1st generation, iPhone SE 2nd generation
• iPhone or Android smartphones with a large display setting
  • If you still have an issue after updating the app to the latest version, you may be able to adjust the display settings to a smaller size to complete the setup.

Audio streaming is available with CRE-E10 on Apple® iPhone®, iPad®, and iPod® devices with iOS™ version 13 or higher installed; audio streaming is unavailable on Android smartphones.

The Sony CRE-E10 OTC hearing aids will support Bluetooth audio streaming for iOS only at this time. Audio streaming is available on Apple® iPhone®, iPad®, and iPod® devices with iOS™ version 13 or higher installed; audio streaming is unavailable on Android™ smartphones. However, the self-fitting process, volume adjustment, and fine tuning are still possible using an Android device with OS 10 or higher via the Sony Hearing Control app.^{2, 3}

The Sony CRE-E10 OTC hearing aids are IP68 rated, which means they are not waterproof, but do have a level of dust and water resistance. 

The Sony OTC hearing aids are only able to be purchased and set up as a pair.

No, this OTC hearing aid will not help with tinnitus.

The battery life of the CRE-E10 OTC hearing aids is up to 26* hours with normal usage after a 4-hour charge. If you need more time, you can charge the hearing aids on the go. A fully charged case provides three complete charging cycles for the hearing aids.

Note: A 30 minute charge will provide up to 6 hours with normal usage.

* Actual performance varies based on settings, environmental conditions, streaming, and other usage.

Instructions are available in the Safety Manual Cleaning and maintenance (P23-24) or you can watch these instructional videos.

You can use the app² to fit the OTC hearing aid and tailor it for your hearing needs:

• Adjust the volume and sound balance (tone)
• Adjust the microphone, so it's easier to hear in noisy environments
• Troubleshoot and change hearing settings on demand

You should have a full hearing evaluation if:

• You have a history or are experiencing ear pain or active drainage or balance problems.
• You hear much better in one ear than in the other.
• You suddenly cannot hear out of one or both of your ears.
• You hear ringing or roaring in one or both of your ears.
• You struggle to hear in all listening environments, including quiet environments.

If you are experiencing any of the above, you should consult with a Hearing Care Professional.

You could be an OTC self-fitting hearing aids candidate if:

• You hear well in quiet environments but struggle in noise.
• You own a smartphone and feel comfortable downloading a new app.
• You are a proactive learner with basic knowledge of how to use a smartphone or tablet.
• You feel cost is a main priority when determining your hearing health care.
• You are interested in some hearing support, but not willing to commit to the traditional hearing aid process.

• You need help to set up and manage self-fitting hearing aids.
• You have not experienced hearing improvement from self-fitting hearing aids.
• You would like additional support with maintenance and care of your hearing aids.

If you are experiencing any of the above, you should consult with a Hearing Care Professional.
