No whistling with a hat
Arthur C.Verified purchase, 🇳🇿 New Zealand
Winter, woolly hat pulled down over my ears, no feedback at all. My old pair could not manage that.

Full day on one charge
NickVerified purchase, 🇳🇿 New Zealand
In at seven, out at eleven at night, still showing charge left. I was expecting to have to top them up in the afternoon.
Worth it
JimVerified purchase, 🇳🇿 New Zealand
Both news to me.
Good in the car
Joe L.Verified purchase, 🇳🇿 New Zealand
Road noise usually swamps everything. I can hear my wife in the passenger seat without turning my head, which is safer as well.

Good value
Julie R.Verified purchase, 🇳🇿 New Zealand
Do the hearing check in a quiet room, not with the television on like I did the first time. Try all three tip sizes before you decide anything is wrong. Give it four days before you judge the sound. Charge the case at the same time as your phone so it becomes one habit instead of two. That is everything I have learned and it took me about a week to learn it.

I stopped nodding along
Alan R.Verified purchase, 🇳🇿 New Zealand
You get into the habit without noticing and it takes a while to break it.

Very good, except in the worst rooms
Irene K.Verified purchase, 🇳🇿 New Zealand
At home, in the car, on the phone, in a normal cafe, they're excellent and I'd give five stars. In a function room with a hundred people and a band I still struggle. I reckon that's true of any hearing aid and probably of anyone's ears, but I'd rather say it than have someone buy expecting different.
Fine for talking, useless for music
Tracey N.Verified purchase, 🇳🇿 New Zealand
Bought them mainly for conversation and they do that well. Tried listening to the radio through them and its not great. Not what theyre for I suppose.
Lasts all day
Simon R.Verified purchase, 🇳🇿 New Zealand
Battery easily lasts all day.

Ordered the week my test came back
Ling R.Verified purchase, 🇳🇿 New Zealand
The follow up appointment was going to be next year and I could not face waiting that long.
Bought on a Friday, wearing them Tuesday
Wendy R.Verified purchase, 🇳🇿 New Zealand
Faster than the appointment letter would have arrived.
Lovely little things
Ali W.Verified purchase, 🇳🇿 New Zealand
And they are little.

Not a toy
Kathleen PalmerVerified purchase, 🇳🇿 New Zealand
Feels properly made. The lid shuts with a click and stays shut.
