Better than nothing, not the transformation the reviews suggested.
OK
Pauline R.Verified purchase, 🇳🇿 New Zealand
Home is better, the phone is better, and I am glad about both. Anywhere with background noise and I am straight back to watching mouths and guessing. My doctor told me afterwards that my loss is probably past what this kind of device can do, which I wish I had asked before ordering rather than after. Three stars because they have helped, just not enough.

The right one is fine, the left has never sounded as good.
Not what I was expecting
Maureen R.Verified purchase, 🇳🇿 New Zealand
I thought Id hear like I used to. I dont. Speech is clearer than it was and thats something, but its not what I had in my head.

Cant wear them for more than a few hours.
Some help, not enough
Julie K.Verified purchase, 🇳🇿 New Zealand
They have made a difference at home. In any kind of noise I am back where I started. I think my loss is beyond what these can do.
So so

Wind and traffic swamp everything.
So so

Better at home than out. Groups are still hard.
Not bad, not great
Clive T.Verified purchase, 🇳🇿 New Zealand
They do something. Whether it was worth it I am still deciding.
NOT FOR EVERYONE

Took me weeks to get used to them.

Barry S.Verified purchase, 🇳🇿 New Zealand
Fine in a quiet room, not much use in a busy one.
Average
joyce h.Verified purchase, 🇳🇿 New Zealand
They help a bit. That is honestly all I can say.
Turned out it was mostly wax
TonyVerified purchase, 🇳🇿 New Zealand
Had my ears syringed and now I barely use them. Get that checked first is my advice.
Alright
Stuart e.Verified purchase, 🇳🇿 New Zealand
Some of the reviews on here describe a transformation. Mine has been an improvement, which is not the same thing. Television better, phone a bit better, group conversation no better at all. I have kept them because an improvement is still an improvement, but I would want somebody thinking about it to read a middling review as well as the good ones.
Bit of an improvement, not a big one
Bryn A.Verified purchase, 🇳🇿 New Zealand
TV and one to one are better, Groups are only slightly better. Youd want to know that before you spend the money.

Anne p.Verified purchase, 🇳🇿 New Zealand
Better than nothing, nowhere near the transformation some of these reviews describe. I am glad I did not spend more.
OK at home, not much use in a crowd
Jackie J.Verified purchase, 🇳🇿 New Zealand
At home and in the car theyve made a real difference. In a busy pub with the match on Im no better off than I was. Depends what your problem is I suppose.

That's a fair review. Directional microphones help in a crowd but nothing worn in the ear solves a loud room with a match on — anyone telling you otherwise is selling. If you haven't tried the noisy-room setting, it's worth a go.
Needed my son to set them up!!

Couldnt do the hearing test on my own, the writing is small. Fine since he did it.

Sorry the text was small for you. You don't have to use the app: ring us and we'll run the hearing check with you over the phone and set them up from that. Same for anyone else reading this.
