No adjustment since day one
Bill A.Verified purchase, 🇳🇿 New Zealand
I set them up once, they have stayed where I put them, and Ive not opened the app since that first afternoon.
Quality
Barry g.Verified purchase, 🇳🇿 New Zealand
They are very good at home, very good on the phone, good in the car, and adequate in a busy cafe. They are not magic and I do not think anything at this money is. What I would say is that the gap between adequate and what I had before is enormous. I was missing entire sentences and filling them in with guesswork.
No pressure change on the plane
Lynne F.Verified purchase, 🇳🇿 New Zealand
I kept them in for the descent and it was fine.
Very happy
Sylvia P.Verified purchase, 🇳🇿 New Zealand
Different make, twice the price, half as good.
Good buy
Chris C.Verified purchase, 🇳🇿 New Zealand
you have to look twice in a bright room.
Comfy
Denis P.Verified purchase, 🇳🇿 New Zealand
All three at once, which is quite an achievement
No Bluetooth
Arthur W.Verified purchase, 🇳🇿 New Zealand
I knew that going in and it doesnt claim otherwise. Still would have liked my calls to come through them.
Better than nothing by a mile
Nancy G.Verified purchase, 🇳🇿 New Zealand
Not the same as my daughter's expensive ones, but a quarter of the price.
Dad is happy
Moira D.Verified purchase, 🇳🇿 New Zealand
My son ordered them for me. Mum manages them on her own at 84.
Happy, but the app is basic

Between us my wife and I used two of them.
Very good with a beard
Carol t.Verified purchase, 🇳🇿 New Zealand
No idea why I thought that would matter, but it does not
good sound in the conservatory
Paul W.Verified purchase, 🇳🇿 New Zealand
Glass room with an echo. Manageable now.
Small and light
Bob ThomasVerified purchase, 🇳🇿 New Zealand
Nobody has noticed them at all. Nothing behind the ear, which I wanted.
No complaints
Tracey H.Verified purchase, 🇳🇿 New Zealand
I knew I would hear more. I did not know that following a conversation had been costing me so much. By four in the afternoon I used to be done in and I put that down to being seventy two. Turns out a good part of it was concentrating on people's mouths all day. That has gone and I have more evening than I used to.
Very comfy
HughVerified purchase, 🇳🇿 New Zealand
Now we both have them and neither of us shouts.
Nothing behind the ear
Martin J.Verified purchase, 🇳🇿 New Zealand
That was the whole reason I chose them. My brother has the beige ones that hook over and you can see them across a room.
