Very happy
GillVerified purchase, 🇮🇪 Ireland
Different make, twice the price, half as good.
No pressure change on the plane
Edward K.Verified purchase, 🇮🇪 Ireland
I kept them in for the descent and it was fine.
Quality
Gordon M.Verified purchase, 🇮🇪 Ireland
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
Edward H.Verified purchase, 🇮🇪 Ireland
I set them up once, they have stayed where I put them, and Ive not opened the app since that first afternoon.
Just right
ANNE L.Verified purchase, 🇮🇪 Ireland
I use drops and there has been no clash.
Very pleased
Denise m.Verified purchase, 🇮🇪 Ireland
And I am usually the pessimist.
Better than expected
bob r.Verified purchase, 🇮🇪 Ireland
Best packing decision I made.
Fine with a cold and blocked ears
Hazel W.Verified purchase, 🇮🇪 Ireland
Slightly muffled for two days, back to normal after.
Really pleased
Anita K.Verified purchase, 🇮🇪 Ireland
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
LesVerified purchase, 🇮🇪 Ireland
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
Colin N.Verified purchase, 🇮🇪 Ireland
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
NeilVerified purchase, 🇮🇪 Ireland
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
Stuart S.Verified purchase, 🇮🇪 Ireland
Very small
Life changer
Joyce d.Verified purchase, 🇮🇪 Ireland
Bending, sweating, sun hat on.
Battery is good
Simon g.Verified purchase, 🇮🇪 Ireland
The case charges them, you just drop them in. In at seven, out at eleven, still charge left.
Works well
Brian K.Verified purchase, 🇮🇪 Ireland
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.
