Amplifiers boost all sounds, while Cearvol hearing aids selectively amplify specific frequencies based on the user’s hearing profile, enhancing speech clarity and reducing background noise. **Q: How can I assess the degree of my hearing loss?** A: You can assess your hearing loss with Cearvol’s app, which offers an online hearing test in just a few minutes. It generates an audiogram to apply to your hearing aids. We also recommend personalizing settings. **Q: What type of hearing loss do these hearing aids support?** A: The Cearvol OTC hearing aids are medical devices used to improve hearing sense for adults 18 and older with perceived mild to moderate hearing loss in both ears. They are not for individuals with severe to profound hearing loss. **Q: How long will it take to get used to my hearing aids?** A: Audiologists recommend 3 weeks for your brain to adapt to wearing hearing aids. In week 1, wear your hearing aids for 1-2 hours per day. In week 2, 3-4 hours per day. After 3 weeks, you are ready for 6+ hours per day and get used to them. **Q: How can I reduce feedback noises like beeping or whistling?** A: You could try lowering the volume, switching to different ear tips, and upgrading the firmware of hearing aids. Additionally, adjust noise reduction and speech enhancement settings to focus on the sounds you want to hear for an improved experience. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best I have ever used! *by V***L on 1 December 2024* ### ⭐⭐⭐⭐ Decent for the money *by M***Y on 30 July 2024* ### ⭐ Had to reinstall app to log in after recent app changes. *by C***S on 5 November 2025* ## Frequently Bought Together - Cearvol Diamond X1 OTC Hearing Aids Rechargeable with Bluetooth Customizable App for iOS/Android, Noise Reduction, for Mild to Moderate Hearing Loss, FSA HSA Fund Available, Black - Behind The Ear Sound Amplifier - BTE Hearing Ear Amplification Device and Digital Hearing Aids for Seniors PSAD for The Hard of Hearing, Noise Reducing, Black, by MEDca - Hearing Aids for Seniors Severe Hearing Loss, Rechargeable with Noise Cancelling (Pair), 4 Modes - Comfort Design Ear Hearing Aid, PSAP --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/658842216-diamond-x1-otc-hearing-aids-rechargeable-with-bluetooth-customizable-app](https://www.desertcart.sk/products/658842216-diamond-x1-otc-hearing-aids-rechargeable-with-bluetooth-customizable-app) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-23*
