Decent
Hazel ClarkVerified purchase, 🇳🇿 New Zealand
Decent.
Solid and discreet
Bill FosterVerified purchase, 🇳🇿 New Zealand
The sound in a busy café is the only weak spot.
Very impressed
S. NguyenVerified purchase, 🇳🇿 New Zealand
I bought these after a quote that would have taken most of my savings. They are very good value and I want to be clear that I am pleased. What they do not do, and what I do not think anything under a few thousand does, is separate one voice from eighty in a hall. My wife's family are loud and Christmas was still hard work. Everywhere else in my life, which is most of it, they have made a real difference. If you are buying for one noisy event you may be disappointed. If you are buying to hear your family, the television and the telephone, I would order them.
Discreet

Good, took a while

Took a while for my own voice to sound right.
Fine, could do with a carry pouch
Pauline HughesVerified purchase, 🇳🇿 New Zealand
The case goes in my bag loose and rattles about.
Happy, but the app is basic
Raj H.Verified purchase, 🇳🇿 New Zealand
Does the check and not a lot else.
Better than nothing by a mile
Nancy G.Verified purchase, 🇳🇿 New Zealand
Not the same as my daughter's expensive ones, but a quarter of the price.
No Bluetooth
Arthur W.Verified purchase, 🇳🇿 New Zealand
I knew that going in and it doesnt claim otherwise. Still would have liked my calls to come through them.
Top marks
Fred Z.Verified purchase, 🇳🇿 New Zealand
Two minutes to swap. Four stars because nobody says that up front.
Happy after a month
Angela R.Verified purchase, 🇳🇿 New Zealand
Took three weeks to fully settle for me. Worth persevering.
Good sound, small case light
Brenda BaileyVerified purchase, 🇳🇿 New Zealand
Hard to see in daylight.
Took me longer than most
Hugh P.Verified purchase, 🇳🇿 New Zealand
Everyone says three days. It took me nearly three weeks before they felt normal and I nearly gave up twice.
Comfortable, sound could be warmer
HowardVerified purchase, 🇳🇿 New Zealand
Slightly bright on some voices. You get used to it.
Good, one wobble
Angela FaleoloVerified purchase, 🇳🇿 New Zealand
The left one went silent one evening. Put it back in the case, took it out, fine ever since. Not happened again in four months.
Four stars, would buy again
Rosemary HemiVerified purchase, 🇳🇿 New Zealand
Nothing wrong with them, just not flawless.
