Straight answers

Everything people ask us.

Orders and delivery

How will I know my order has shipped?

You get an email with your tracking number the moment your order leaves us. Delivery times for your country are in our shipping policy.

How long does delivery take?

It depends on where you are. Your delivery window is shown at checkout and set out per country in our shipping policy. Delivery is free on every order, to every country we ship to.

How do I track it?

You get an email with a tracking number and a live link the moment it is dispatched. You can also use our tracking page.

Which countries do you ship to?

Yes. We ship worldwide, with free delivery everywhere and the same 90-day trial and 2-year guarantee.

Returns and refunds

What is the 90-day trial?

Ninety days from delivery to use it in your real life: the dinners, the phone calls, the television. If it does not earn its place, send it back for a full refund. No questions, no restocking fee.

How do I start a return?

Email us with your order number and we send you the instructions. A human reads it and replies. There is no form to defeat.

When do I get my money?

Within 5 to 10 working days of the return arriving, back to the card you paid with.

Guarantee

What does the 2-year guarantee cover?

Faults. If the device or case stops working properly through normal use within two years, we repair or replace it.

What is not covered?

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

Using your device

Is this a real hearing aid?

Yes. Certus One is a certified hearing aid 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.

Will it help with severe hearing loss?

No, and we would rather say so before you buy. Certus One is designed for mild to moderate loss. For profound loss, a prescription aid fitted at a clinic is the right route.

It whistles. What do I do?

Almost always the tip is not sealing. Try the next size up from the 12 in the box. A proper seal is what stops the whistle.

How long does the battery last?

16 hours per charge, and 60 hours with the case, which is about four more full charges away from a plug socket.

Do I need an app?

No. There is nothing to pair, download or update. Put them in and they work.

Still stuck? A person will answer.

Not a bot, not a ticket number. Tell us your order number and what is going on, and you will get a real reply.
