Better in the second month

They did not change. I did. Everything that seemed sharp at the start settled into normal somewhere around week three.

Wife reckons I'm back
Siobhan N.Verified purchase, 🇳🇿 New Zealand
I'd gone quiet the last few years. Not deaf exactly, just not joining in, because following a conversation in a group was more effort than it was worth. She said last week I'm back to how I was. Took about a week to feel normal. Wear them all day, no soreness.

Good in the wind on the coast path
Arthur K.Verified purchase, 🇳🇿 New Zealand
Some noise but not the roar I expected.
Good value
MICHAEL O.Verified purchase, 🇳🇿 New Zealand
I have no argument with the sound or the comfort. My complaint is the beeping when the battery is low. It is too quiet to hear, which is a strange thing to get wrong in a device for people who cannot hear well, and I have been caught out twice.

Do the hearing test in a quiet room
W. RangiVerified purchase, 🇳🇿 New Zealand
Did mine with the washing machine on and got a rubbish result. Did it again properly and it was completely different.
I can hear my key in the lock
Yvonne M.Verified purchase, 🇳🇿 New Zealand
Which sounds like nothing but it is the sort of thing you do not notice going until it comes back.
Ok
Howard R.Verified purchase, 🇳🇿 New Zealand
Glad I ordered them.
Discreet

Discreet
sat through a two hour talk
WendyVerified purchase, 🇳🇿 New Zealand
Village hall, terrible acoustics, a speaker who mumbles. I followed it. In January I would have given up after ten minutes

I was ready to help my dad and he did not need me.
