Snug fit.
Sound comes on instantly

No warm up, no delay.
My mother in law
Gary G.Verified purchase, 🇳🇿 New Zealand
She has said thank you twice, which anyone who knows her will tell you isnt a thing that happens.
One ear worse than the other
Phil N.Verified purchase, 🇳🇿 New Zealand
My left is much worse and I expected them to be uneven. They are not. The balance across the two is better than I hoped.
Bought for my mother
Dimitri A.Verified purchase, 🇳🇿 New Zealand
She is 84 and has turned down every bit of help anyone has offered her. She has worn these every day since Easter. I dont question it.

A little rush of noise, nothing that spoiled it.
The left one stopped charging after five weeks
IeuanVerified purchase, 🇳🇿 New Zealand
I want to be fair because up to that point I was going to write a five star review. Comfortable, discreet, and a real difference on the telephone, which was why I bought them. Five weeks in, the left one stopped taking a charge. Sat in the case overnight, no light, nothing. I tried the other slot, I tried a different plug, I cleaned the contacts with the brush like the card says. Rang them and they were perfectly polite and offered a replacement or a refund and I took the refund because by then I had lost confidence in them lasting. To be clear, the refund was quick and nobody argued with me. One star is for the product failing inside six weeks, not for how they dealt with it.

Nice to hear the rain again
Stan HillVerified purchase, 🇳🇿 New Zealand
Sounds silly written down.
six weeks of daily wear
Doreen G.Verified purchase, 🇳🇿 New Zealand
Nothing has gone wrong, nothing has come loose, nothing needs adjusting. I clean them with the brush on a Sunday and that is it.
No pinch, no rub, no ache

I could never use those. These made it irrelevant.
