Theres a knack to putting them in
Norma SimpsonVerified purchase, 🇳🇿 New Zealand
Had them sitting too shallow for three days and thought they were rubbish. They werent, I was.
Dont put them in a pocket with keys
Vince t.Verified purchase, 🇳🇿 New Zealand
Scratched the case. Sound is fine.
Good value
Sanjay S.Verified purchase, 🇳🇿 New Zealand
I live on the front and walk most days. In wind there is a rush of noise that swamps the person next to me, and Ive taken to taking them out for the walk and putting them back in when we get to the cafe. Everywhere else they are excellent.
Pleased overall
Maureen h.Verified purchase, 🇳🇿 New Zealand
Restaurants are still hard work. Home and phone are much better.
Took me longer than most to settle
Patricia M.Verified purchase, 🇳🇿 New Zealand
Ten days before I stopped noticing my own voice. Everyone else seems to manage it in two or three.
Quality
Phil D.Verified purchase, 🇳🇿 New Zealand
I have missed it twice.
Lost one down the sofa in week two
Rosemary R.Verified purchase, 🇳🇿 New Zealand
My own fault. They are very small. Use the case.
Alright
Denise C.Verified purchase, 🇳🇿 New Zealand

Different size in each ear
Ray S.Verified purchase, 🇳🇿 New Zealand
Medium left, small right, apparently thats normal. Nobody told me.
Spare tips arent labelled
Frances J.Verified purchase, 🇳🇿 New Zealand
All loose in one bag and I cant tell small from medium by looking.
Reply from Certus Hearing
You're right, the spare tips should be labelled. We're changing the packaging. In the meantime the three sizes go smallest at the bottom of the bag to largest at the top.
Four stars because of the wind
Patricia K.Verified purchase, 🇳🇿 New Zealand
Blustery days give me a rushing noise. Otherwise no complaints.

Instructions are a bit thin
Trevor ChenVerified purchase, 🇳🇿 New Zealand
Gets you going in five minutes but says NOTHING about what to do if one ear sounds different to the other. Had to ring up.
Very good but the first week is odd
Ann R.Verified purchase, 🇳🇿 New Zealand
Four stars not five only because of the settling in, which I don't reckon gets said loudly enough. Day one and two everything is bright and clattery. About day six my brain sorted itself out and since then they've been excellent, I wear them breakfast to bed. Just don't expect to put them in and be thrilled straight away.

Pleased, small niggles
Colin C.Verified purchase, 🇳🇿 New Zealand
Sound is good and comfort is good. The low battery warning is very quiet and Ive missed it twice and been caught out.
No light on the case
John t.Verified purchase, 🇳🇿 New Zealand
Cant tell how much charge is left in the case. You just have to guess or plug it in every few days. Everything else is good.
Reply from Certus Hearing
Fair point on the charge indicator — the case gives you a full charge from empty in about two hours, so most people just leave it plugged in overnight, but you shouldn't have to work that out yourself. It's on the list for the next revision.
Very good, except in the worst rooms
Irene K.Verified purchase, 🇳🇿 New Zealand
At home, in the car, on the phone, in a normal cafe, they're excellent and I'd give five stars. In a function room with a hundred people and a band I still struggle. I reckon that's true of any hearing aid and probably of anyone's ears, but I'd rather say it than have someone buy expecting different.
Fine for talking, useless for music
Tracey N.Verified purchase, 🇳🇿 New Zealand
Bought them mainly for conversation and they do that well. Tried listening to the radio through them and its not great. Not what theyre for I suppose.
