Faults. If a hearing aid or case stops working properly through normal use within two years, we repair or replace it.

Loss, and damage from accidents or water beyond normal daily wear. Ear tips are consumable, which is why 12 come in the box.

Yes. Add the Lifetime Warranty at checkout. Your 2-year warranty never ends: both hearing aids, the batteries and the charging case, for as long as you own them. Any fault is repaired or replaced free, postage both ways included. One-time payment, no registration.

Yes. Certus One, Certus Pro and Certus Max are certified hearing aids for mild to moderate hearing loss. That is a regulated category with real requirements behind it, which is exactly what an unregulated “sound amplifier” does not have.

For Certus One, no: it works completely on its own, with one button. For Certus Pro, yes, once: the five-minute setup and hearing check run from the free Certus app on iPhone or Android. After that, Pro works all day on its own, and you open the app only to change volume or listening mode. Certus Max is made for phone calls and music, so you need a phone with Bluetooth. You can change its volume and mode on the touchscreen case.

Only Certus Max. It pairs with iPhone and Android phones over Bluetooth, like earbuds, and plays calls, video calls, music and audiobooks in both ears. Certus Pro uses Bluetooth for its app only: calls stay on your phone. Certus One has no Bluetooth.

Take the aids out of the case so they switch on, open Bluetooth on your phone and choose Certus Max, the same way you pair earbuds. You only do it once; after that they reconnect by themselves. Stuck? Email us and a person will walk you through it.

Up to 15 hours a day of hearing. Streaming uses more: about 5 hours of calls or 6 hours of music. The touchscreen case refills the aids 4 to 5 times.

Start with the one that feels snug but comfortable. Five sizes come in the box. If the sound is thin or it whistles, go one size up; if it presses or aches, go one size down.

Keep the aids sitting in the open case next to your phone, with Bluetooth switched on, and follow the QR guide from the box. Pairing happens once and takes about a minute. If it does not take, close the case lid, wait ten seconds, open it and try again. Still stuck? Email us and a person will walk you through it.

No, and we would rather say so before you buy. Certus is designed for mild to moderate loss. For severe or profound loss, see an audiologist for fitted hearing aids.

Almost always the tip or dome is not sealing. Try the next size up: 12 tips come with Certus One, 5 dome sizes with Certus Max. A proper seal stops the whistle.

Certus One and Certus Pro: 16 hours per charge, and 60 hours with the case, which is about four more full charges away from a power point. Certus Max: up to 15 hours a day, about 5 hours of calls.

No. There is nothing to pair, download or update. Put them in and they work. Certus Pro and Certus Max use the free app.
