I worked it out. A line or two would have helped.

Very good with one caveat
Vic o.Verified purchase, 🇳🇿 New Zealand
If you have severe loss these are not going to be enough.
Good but read this first
Tom R.Verified purchase, 🇳🇿 New Zealand
Very good, but they need charging every night without fail.
Good, not a miracle
Rosemary K.Verified purchase, 🇳🇿 New Zealand
Big difference at home, a real difference on the phone, not much difference in a crowded hall. That seems fair for the money.
Have to charge them every night
MARION K.Verified purchase, 🇳🇿 New Zealand
Which is fine if you remember. I have forgotten twice and had a quiet morning both times.
Four stars
David T.Verified purchase, 🇳🇿 New Zealand
Had to try all three tip sizes.
Case is easy to lose
F. OSullivanVerified purchase, 🇳🇿 New Zealand
Small and white and my kitchen is full of small white things. My problem not theirs.
Slow post
Terry H.Verified purchase, 🇳🇿 New Zealand
Good, delivery was slow
Good but read this first
Ian C.Verified purchase, 🇳🇿 New Zealand
Try all three tip sizes before you decide anything. I nearly sent mine back over a whistle that a bigger tip fixed in ten seconds.
VERY IMPRESSED
Halina P.Verified purchase, 🇳🇿 New Zealand
I am writing this partly as a warning against giving up early. Days one to three, everything was sharp and my own voice sounded like it was in a bucket, which I now know is normal and passes. Day four to nine, a whistle every time I put my glasses on, which I was sure meant a fault. It was the tip size. Day ten to sixteen, better, but I was still aware of them all the time. Somewhere in week three it stopped being a thing I thought about. If I had sent them back at day nine, which I very nearly did, I would have posted an angry two star review and I would have been wrong. Four stars rather than five only because none of that was explained anywhere in the box.
Best buy
Kevin k.Verified purchase, 🇳🇿 New Zealand
It would live round my neck if it had one.
Does what it says
George W.Verified purchase, 🇳🇿 New Zealand
I would have liked a spare charging case for travelling.
Works well, took me a week
LYNNE P.Verified purchase, 🇳🇿 New Zealand
Longer to get used to than the box suggests, but I got there.

Four stars, wind
Christine s.Verified purchase, 🇳🇿 New Zealand
On a still day I have no complaints at all. On the seafront there is a rush of noise that drowns out whoever I am with.
Good, one gripe
P. MurphyVerified purchase, 🇳🇿 New Zealand
They do what they say and I am pleased. The instructions could tell you more about cleaning, and the case light is hard to see in daylight.
Nearly returned them on day three
Gary K.Verified purchase, 🇳🇿 New Zealand
So glad I didnt. Somebody should say louder that the first few days are odd.
Does the job with one gripe
Tony m.Verified purchase, 🇳🇿 New Zealand
The tips are fiddly to change with arthritic fingers.

Good, small learning curve
Terry g.Verified purchase, 🇳🇿 New Zealand
Two or three days of everything sounding sharp.
Glad I did
Julie HarrisVerified purchase, 🇳🇿 New Zealand
I want to be honest because I nearly returned them twice. Week one everything was sharp and my own voice sounded like a bucket. Week two the whistle, which turned out to be the wrong tips. Week three it all settled and I have not thought about them since. If I had sent them back on day nine I would have written a very different review.
Only one colour
Hilary H.Verified purchase, 🇳🇿 New Zealand
Beige. My hair is dark. If you look properly you can see it. Nobody has yet but I know its there. Photo so you can see the colour.
