Aisha M.Verified purchase, 🇺🇸 United States
I have never been able to tolerate anything in my ear. Earplugs, earphones, the lot. I gave it eleven days because I wanted it to work and by the end of it I was taking them out at lunchtime every day. That is me, not the product. The return was straightforward and the refund was in my account in under a week, which is why it is two stars and not one.

I wanted calls coming straight into them. They dont. My mistake for not checking properly. Returned.

You're right that we don't stream calls. It's on the spec page but it clearly isn't hard enough to find, and that's on us. Certus One is an amplification device, not a headset.

Not enough for me im afraid.

Didnt suit my ears at all...
Yasmin F.Verified purchase, 🇺🇸 United States
Mines severe in both ears and these didnt cut it. Sent them back and got my money.

Thanks for the straight review. Severe loss in both ears is outside what Certus One is built for — our fitting range goes up to moderate — so this was the right outcome rather than a fault. Worth saying plainly for anyone reading with a similar audiogram.

My loss is too bad for these. Got a refund.

Never could with earplugs either so I should have known. Nothing wrong with them, just not for me. Sent back.

Nothing we can do about that one, but thank you for saying it plainly — it's genuinely useful for anyone else who's never got on with earbuds.
