Very happy
Sylvia P.Verified purchase, 🇳🇿 New Zealand
Different make, twice the price, half as good.
No pressure change on the plane
Lynne F.Verified purchase, 🇳🇿 New Zealand
I kept them in for the descent and it was fine.
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 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.
Just right
Eileen G.Verified purchase, 🇳🇿 New Zealand
I use drops and there has been no clash.
Very pleased
Wendy c.Verified purchase, 🇳🇿 New Zealand
And I am usually the pessimist.
Better than expected
Gordon H.Verified purchase, 🇳🇿 New Zealand
Best packing decision I made.
Fine with a cold and blocked ears
Gordon J.Verified purchase, 🇳🇿 New Zealand
Slightly muffled for two days, back to normal after.
Really pleased
Don M.Verified purchase, 🇳🇿 New Zealand
Two appointments, a hearing test, and then a man in a nice office talking me through finance options for a number I will not repeat here. I said I would think about it. I never went back. I bought these to see what a tenth of the money buys you and I have been wearing them since April. In the house they are very good. On the phone they are very good. In a restaurant I can hear the person opposite, which is the thing I actually wanted
Guessing is over
Patrick R.Verified purchase, 🇳🇿 New Zealand
I had got very good at answering questions I had not heard properly. That is a horrible way to live and I did it for years.
Six weeks with a hearing dog
Ken PalmerVerified purchase, 🇳🇿 New Zealand
I have a dog for other reasons and I was told these might upset him. They have not. He responds to me talking at a normal volume now, which he was not doing when I was shouting at him without realising I was shouting.
Spot on
Colin c.Verified purchase, 🇳🇿 New Zealand
Not the trial I would have chosen. Stone church, an organ, a lot of quiet talking afterwards in a hall with a hard floor. I heard the eulogy for my friend of forty years, which I would have missed entirely, and I have thought about that a fair bit since.
Small

Very small
Life changer
Pat J.Verified purchase, 🇳🇿 New Zealand
Bending, sweating, sun hat on.
Battery is good
Rosemary P.Verified purchase, 🇳🇿 New Zealand
The case charges them, you just drop them in. In at seven, out at eleven, still charge left.
Works well
Irene HolmesVerified purchase, 🇳🇿 New Zealand
It takes about ten minutes and you tap the screen when you hear a beep. Mine came back showing a lot gone at the top end on both sides, worse on the right. It was not a nice half hour. It also explained the last five years, why I could tell that somebody was talking to me but not what they were saying, and why the television has been at war with my wife.
Grandson's school play

Front row and every word came through.

No sore ears at all.
